Zyrexin – With their exclusive right to the wonder compound Butea Superba, it is no wonder this five year old product is still so popular. Go into any Wal-Mart and chances are you’ll see someone buying a bottle of this dynamite product. It has been the number one selling Viagra alternative at retail stores for three years in a row. Not quite as powerful as Activator Rx, but still a great product. No other product sold at retail stores comes close to being as effective as Zyrexin. Was the king of the hill in 2009, but has recently been surpassed only by Activator Rx. Available at Wal-Mart, CVS, Rite Aide, GNC and over the Internet at www.zyrexin.com

What is Zyrexin?
Zyrexin is all-natural male enhancement supplement that utilizes the only ingredient awarded a United States patent, called butea superba. According to Zyrexin, the supplements begin working in less than an hour, making it easier to maintain an erection without needing additional assistance. That's not all, though: it also make your erection bigger, harder and more rigid, making sexual intercourse more pleasurable.

Ingredients: Zyrexin contains xanthoparmelia scabrosa, cnidium monnier, and butea superba.

Does it Work?: Absolutely. Not only is butea superba rich in prostate-boosting sterols, such as beta-sitosterol and stigmasterol, there is also plenty of evidence supporting its ability to improve erectile function. According to a study reported on PubMed.gov, the National Institutes of Health's medical study database, over 82% of men who took butea superba for three months experienced significantly better erectile function, which helped improve erection strength and rigidity. The study also concluded butea superba was not toxic, with no side effects noted by any participants.

Xanthoparmelia scabrosa and cnidium monnier are also both identified as potent libido boosters in Chinese medicine, backed up by plenty of anecdotal evidence. It's not clear how it works, but men who took both ingredients noticed a significant increase in libido, improving their performance in the bedroom. An increase in libido also improves sexual stamina, reducing the symptoms of premature ejaculation.

Is it Safe?: Yes. No known side effects or contraindications are associated with any of Zyrexin's ingredients, including butea superba. It also does not cause any dangerous reactions with other drugs or supplements.

Grade: A. Not only is Zyrexin effective, it's virtually free of any side effects—something you won't hear from Viagra or Cialis. It's also one of the fastest working supplements—it literally goes to work in less than an hour to improve erectile function. Zyrexin earns an A for using high quality ingredients that are proven to reduce erectile dysfunction (ED) and premature ejaculation, something over-the-counter enhancement supplements can't do.

Grade: A

What is Vitrix?
Vitrix is a male performance aid that claims to elevate testosterone, the male hormone responsible for promoting mass muscle gain, hardness and libido.  Unlike other bodybuilding supplements, Vitrix doesn't need to be cycled in order to maintain its effectiveness.  They credit this natural enhancement to tribulus terrestris, an all-natural plant extract rich in saponin and protodioscin.

Ingredients: Vitrix contains German tribulus terrestris and a liquid proprietary phyto-nutrient blend of vitex agnus castus, avena sativa, eqidmedium and eurycomo longfolia jack.

Does it Work?: It's unclear.  Tribulus terrestris hasn't been proven to facilitate muscle or testosterone growth--many studies returned varying, unstable results.  Numerous studies also failed to raise testosterone levels in men.  The verdict right now is that tribuls terrestris is not an effective supplement for increasing testosterone levels.

But tribulus terrestris isn't completely ineffective.  One study, conducted by National University Hospital, suggests it contains aphrodisiac properties--including an increase in ejaculation, sexual desire and libido.  Although researchers observed these results in animals, not humans, it strongly suggests it may be a viable sex aid for several sexual dysfunctions, including erectile dysfunction.  

Is it Safe?: Almost--except for one major problem.  Tribulus terrestris can cause a condition called gynecomastia, or male breast enlargement.  This condition is not reversible.  Drugs and surgery can correct some of the breast growth, but it isn't guaranteed.

Grade: C.  Just because it's all-natural doesn't always mean it's safe or effective--Vitrix being a perfect example of this.  Tribulus terrestris can also increase male breast growth, which can be emotionally difficult to deal with.  There is definitely some evidence it can improve the libido, but this only targets one part of sexual dysfunction—erectile function and sexual desire are more important factors.

Grade: A

What is Orexis?
Orexis is a non-prescription male enhancement supplement that works by boosting the libido shortly before intercourse to prevent erectile dysfunction (ED), or an inability to maintain an erection.  Like other supplements, Orexis provides erectile support by increasing blood flow to the penis, which helps it stay fuller and more rigid when stimulated.  This also causes an indirect benefit--increased stamina during sexual intercourse.  To enable it to work, Orexis recommend using their supplement 45 minutes before beginning sexual stimulation to promote penis rigidity and fullness.

Ingredients: Orexis contains a proprietary blend of horny goat weed, yohimbe extract, tribulus and other ingredients, which they aren't willing to reveal on their website.

Does it Work?: There is some evidence it may work.  According to a report in the Journal of Urology, horny goat weed was shown to induce erections in rats, improving their copulatory performance.  Other evidence also suggests it contains a compound chemically similar to sildenafil, the active ingredient in Viagra.  Some researchers suggest it may be a viable alternative to Viagra, although it hasn't been approved for this use by the United States Food and Drug Administration (FDA).

Yohimbe has also been shown to improve erectile function, although its reported effects are derived from anecdotal, not scientific, evidence.  There is scientific evidence that it helps improve the libido, especially when combined with ginseng or l-arginine.  But this comes at a huge risk--yohimbe is know to worsen anxiety conditions, and can trigger panic attacks and hallucinations.

Is it Safe?: No.  Yohimbe extract can worsen anxiety conditions, such as generalized anxiety disorder (GAD) or social anxiety disorder (SAD).  It can also cause hallucinations, panic attacks, flushing of the skin, dizziness, an increase in heart rate, high blood pressure and insomnia.  People with heart, blood or psychiatric problems should avoid taking supplements containing yohimbe extract.

Grade: C.  Orexis may reduce ED by improving erectile function, but this comes at an increased risk—some of its ingredients worsen anxiety and heart-related problems, such as rapid heart rate and panic attacks.  If you have a history of heart, blood or psychiatric disorders, this is not an ideal supplement for you.

Grade: A

BETTERMAN –Excellent product that made it into the Top 15. The Chinese formula is over 50 years old and was brought to the U.S. by Peipei Wu Wishnow, Ph.D., a founder of Massachusetts based Interceuticals. A research scientist, Wu Wishnow was born in China where she perfected the art of preparing remedies. The formula consists of 18 pure Chinese herbs. The two active ingredients in the formula are Wu Wei Zi, a dried fruit, and Yin Yang Huo, a dried plant, both of which are non-toxic. The recommended dosage is to follow two 20-day cycles – one capsule twice a day for 20 days, followed by a three-day break followed by another 20-day cycle. Reports have been positive. Best results usually require three twenty days cycles. Results and reports have been positive. GRADE B+

What is Betterman?
Betterman is a male enhancement supplement that helps reduce urinary frequency and erectile dysfunction (ED), two common problems that affect American men over age 40. Using a variety of Chinese herbs and extracts, it naturally improves blood circulation, sexual function, and the strength of blood vessels, making erections easier to maintain. Betterman is taken in cycles to ensure the body is constantly stimulated by its ingredients, with results seen within weeks of use.

Ingredients: Betterman contains ginseng root, yam rhizomes, white peony root, epimedium, deer antler, astragalus root, poria fungus, morinda root, cornus fruit, wood cotton bark, dong quai root, wolfberry fruit, rehmannia root, Szechuan Lovage root, schisandra fruit, Siberian ginseng, cynomorium and cinnamon bark.

Does it Work?: Probably. Ginseng is a very popular—and effective—herb for the treatment of erectile dysfunction, which currently affects nearly 30 million men in the United States. According to one study conducted by Yonsei University in 1995, 60% of men who took ginseng regularly significantly reduced erectile difficulty, making it easier to maintain an erection without additional support.

Yam rhizomes also contain vitamin C, which helps strengthen veins leading to the penis, increasing penile rigidity. Strong veins also make it easier to get an erection, eliminating the symptoms of erectile dysfunction.

Is it Safe?: Yes. It may cause negative interactions with other drugs, however, including phenelzine and coumadin. It may also worsen the effects of digoxin for people suffering from congestive heart failure. If you suffer from congestive heart failure, seek medical advice before taking Betterman.

Grade: B. Betterman contains several key ingredients that help reduce erectile dysfunction, increasing penis rigidity and hardness without the use of harsh chemicals. Over time, Betterman may reduce your symptoms of erectile dysfunction. This is an excellent product for improving your sexual stamina and power.

Grade: A

What is Vialipro?
Vialipro is a fast-acting male enhancement supplement that claims to improve erectile rigidity, orgasm control and sexual stamina right before intercourse, improving the quality of your sex life.  Vialipro isn't intended for daily use--instead, they recommend using it 30 minutes before intercourse to temporarily heighten your arousal.  According to a study reported on their website, it's extremely effective--over 80 percent of men reported having firmer, longer-lasting erections after taking the supplement.

Ingredients: Vialipro contains l-arginine, safed musli extract, shilajit, velvet deer, ashwagandha root, smilax extract, maca extract, saffron and catauba extract.

Does it Work?: Studies suggests it's not.  Velvet deer has been indicated as a treatment for impotence in traditional Chiense medicine, but clinical studies show it doesn't have any efficacy against any sexual disorders.  Drugs.com says there is little evidence of its efficacy against any health problem, aside from arthritis (it may contain a compound that treat arthritis pain).

L-arginine was shown to reduce symptoms of ED in one study, but further studies haven't replicated these benefits.  According to Cathy Wong, About.com's Alternative Medicine guide, some health practitioners claim it treats ED because it increases nitric oxide, which also occurs in sildenafil (Viagra).  But with few studies proving its efficacy, it's not clear if it can improve any ED symptoms.

To make matters worse, ashwaganda root, smilax and maca extract have not been shown to improve sexual function.  No studies have indicated it as effective treatments for ED, premature ejaculation or other types of sexual dysfunction.

There is also some evidence the study reported on their website may be biased, and could have been used to mislead customers.

Is it Safe?: No.  L-arginine may cause indigestion, headache, nausea, an increase in stomach acid and changes in potassium levels.  Men with diabetes, digestive problems, heartburn or kidney disease need medical approval before using supplements containing l-arginine.  It can also make the symptoms of genital herpes worse.

Grade: C.  Overwhelming evidence shows Vialipro contains ineffective, and potentially dangerous, ingredients, which don't improve erectile or sexual function in any way.  Although l-arginine has been indicated as a possible treatment for ED, it also causes several significant side effects, which can be dangerous for men with diabetes, kidney disease, digestive problems or genital herpes.

Lightning Rod –One pill can put a little lightning in your rod – but now as much as you might be looking for at $11.00 a pill. While it does work (remember there are plenty of products out there that promise to make you rock hard in less than an hour and they never, ever, ever, do a thing), it’s just not as strong as the elite products. Sold mostly around Las Vegas and Phoenix, it relies too much on the clever named and logo appeal of putting lightening into your rod. Two capsules would work great but then you are spending $22 for one does – too high. Good not great.

Grade: A

LEVITROL - The ads make it look like it is Levitra in my opinion. There is just a 2-letter difference in the names. Produced by a company called In Q Marketing based in the State of Maine, "In the Q" is a telemarketing phrase that refers to how many people are on hold or in the "Q." I think this name indicates this company is a marketing company and nothing more. They have no website and are just a marketing outfit that happens to be selling sexual supplements. They do not make the false and sleazy claims like some of the bad guys in the industry about adding inches to your penis, and for that they are to be commended. But the formula, delivered in tablet form, has L-Arginine in the less-desired HCL form. The independent lab analysis showed that it contained over 600mg per tablet, which is not bad, and is even sensational when you compare it to Procyclon which is also advertised heavily in the newspapers. The yohimbe is not an extract, but is in powdered form, which is significantly weaker. Once again though, the levels were not bad. GRADE B

Grade: A

S Stamina - A Stamina Rx imitator that is nowhere near as good as the original Stamina Rx. Another one pill, high priced product that works – but not as good as you would wish, especially for the high price it commands. Too many ingredients in the formula to leave enough room for a few strong ingredients. Needs to eliminate a few compounds and up the amount of yohimbe and L-Arginine, and then this could be a Top 10 product. Still better than average. Sold in some GNC stores and at a many independent health food stores nationwide.

Grade: A

What is Orviax?
Orviax is a natural male enhancement supplement that claims to promote longer, harder erections, boost the libido and increase stamina, reducing sexual dysfunction.  It supposedly works within 20 to 30 minutes to prepare the body for intercourse, working even faster than Cialis, an FDA-approved sexual dysfunction drug.  Orviax credits its success to its proprietary blend of 11 herbal ingredients, including damiana, epimedium and gingko biloba, which they claim are completely free of any side effects.

Ingredients: Orviax contains damiana, horny goat weed, ashwagandha root, avena sativa, ginkgo biloba, Korean ginseng, maca root, muira puama, saw palmetto, tribulus terrestris and l-arginine.

Does it Work?: It might.  Orviax contains horny goat weed, an herb shown to contain pro-erectile properties in several studies.  It was shown to reduce sexual dysfunction by stimulating the penile tissues during sexual stimulation, resulting in harder, longer lasting erections.  Some researchers even believe it's as effective as sildenafil, better known by its trade name Viagra.

Ginseng also reportedly increases sexual stamina and libido because of its effect on these same tissues.  Ginsenoside, a chemical found in Ginseng, improves erection strength by stimulating the erectile tissues, making it easier to maintain an erection.  It is considered a somewhat effective treatment for erectile dysfunction (ED).

But many of Orviax's ingredients are also proven not to work, including maca root, muira puama and avena sativa.  Although it was used in traditional Chinese and Indian medicine to treat various sexual dysfunctions, it's been proven ineffective by various national studies.  Some of these ingredients are also unsafe to take.

Is it Safe?: No.  Ginseng can cause nausea, diarrhea, headaches, nosebleeds, sudden changes in blood pressure and breast pain.  Men on antidepressants should take extreme caution--ginseng can also cause mania if used with certain antidepressants.  Ginkgo biloba also worsens bleeding, and should not be taken by people on anticoagulants.

Grade: C.  Orviax claims to make you bigger and thicker down there, but the evidence doesn't add up--in fact, only a few of its ingredients promote sexual stamina.  Orviax comes up short when it comes to efficacy, but goes long when it comes to side effects, something this supplement isn't short of.

Grade: A

What is P Boost?
P Boost is a fast-acting male enhancement supplement that claims to make erections harder, firmer, and easier to maintain, reducing the complications of erectile dysfunction (ED), a common sexual disorder.  Unlike other ED treatments, P Boost is completely all-natural, and only utilizes herbs, vitamins and extracts to promote erectile health.  But research complied on its ingredients tells a different story about this supposed "immediate-acting male enhancement" supplement.

Ingredients: P Boost contains ginseng, wolfberry fruit, glangal fruit, epimedium sagittatum, rehmannia root, cassia bark, yam, and vitamins B1, B12 and E.

Does it Work?: It might--but it's probably not very effective.  The only ingredient that was proven to improve erectile strength is ginseng--some studies suggest it strengthens the penile tissue, enabling harder, thicker erections.  It's important to note these effects were only observed in animals, not humans, and its efficacy may not be the same for humans.  Other evidence suggests it improves the libido, although researchers believe this is a placebo effect.

Wolfberry fruit, better known as the goji berry, has been rumored to promote erectile strength, but studies are lacking on its efficacy.  The same applies to rehmannia root, a common ingredient used in traditional Chinese medicine.  Overall, P Boost contains only one ingredient shown to improve erectile strength, and even its effects on humans is questionable--its sexual benefits were only observed in animals, not humans.

Is it Safe?: No.  Ginseng can cause insomnia, gastrointestinal problems, an increased risk for bleeding and headaches.  Wolfberry is also a potentially toxic fruit, and can increase bleeding in some people.

Grade: C.  P Boost may claim to promote harder erections, but there is little evidence that supports this.  Ginseng may increase the frequency of erections, but the rest of its ingredients do not, which may limit its efficacy against ED.  P Boost may not be able to promote harder erections--all-natural isn't an indicator of efficacy in this case.

Grade: A

Desire – This three pill blister pack sold at Vitamin Shoppe and gas stations, is more marketing gimmick over formula. While it does work better than most, its’ still not the elite product it claims to be. The formula has a few innovative twists, but the results are only slightly better than average. This is a new company and to produce a product like this with their first try is impressive. I think after they get more consumer feedback, they will be able to tweak their formula and look for Desire to get better over time. Hard to find on the Internet, best bet if you are interested in trying Desire is a Vitamin Shoppe retail store.

Grade: A

What is Vimax?

Vimax claims to be a completely natural--and safe--supplement for improving pleasure and the strength of erections during intercourse, without the unwanted side effects of some prescription drugs.  Vimax can be used daily or as a quick pick-me-up 30 minutes before intercourse, acting similarly to the prescription drug Cialis.  They claim you'll need to use three to four bottles of Vimax to see its full results, however.

Ingredients: Vimax contains muira puama, velvet, ginkgo biloba, damiana, cayenne, oats, avena sativa, ginseng, panax ginseng, caltrop and tribulus terrestris.

Does it Work?: It can improve erectile function.  According to a story reported by About.com, 60 percent of men who took ginseng regularly noticed an improvement in symptoms caused by erectile dysfunction (ED), or an inability to maintain an erection.  Other clinical studies show it improves copulatory performance, although it isn't clear what it specifically promotes.

It hasn't received an official approval from the FDA for this use, though--there are some side effects associated with regular use.

But don't expect more benefits like these from muira puama, damiana and caltrop.  None of these ingredients have been shown to improve erectile function, rigidity or the libido.  Some researchers believe any reported benefits are more likely caused by a placebo effect, not from the actual ingredient.

Is it Safe?: No.  Ginseng can cause rapid changes in blood pressure, gastrointestinal problems and insomnia.  If you take antidepressants, you cannot take supplements containing ginseng--it can trigger dangerous mania-like symptoms.

Grade: C.  There's no doubt Vimax contains important benefits for men suffering from erectile problems, but it isn't the cure-all for all sexual problems.  It's also not safe, despite claims it is safe.  With a slew of ineffective ingredients and problems with its safety, Vimax probably isn't the best male enhancement aid for men battling erectile dysfunction.

Grade: A

What is Lexaryn?
Lexaryn is an all-natural male enhancement supplement that claims to treat erectile dysfunction (ED), a common male dysfunction disorder.  It even claims it is more effective than Cialis, an FDA-approved drug.  But Lexaryn claims you'll get more than a decrease in ED symptoms: it also says it can increase penis length permanently, make erections harder, and safely boost the sex drive.

Ingredients: Lexaryn contains yohimbe bark extract, epimedium, ashwagandha root, maca root, l-arginine, dimethylglycine (DMG), l-tyrosine, choline, nicotinamide adenine dinucleotide (NADH), tribulus terrestris and bioperine.

Does it Work?: It may work.  Yohimbe bark has been shown to reverse symptoms of ED and other sexual dysfunctions, including orgasmic dysfunction and ejaculation dysfunction.  Several clinical trials suggest it may be a viable alternative treatment for ED, although many health organizations don't currently recommend it--regular use can cause serious side effects, such as panic attacks and hallucinations.

Epimedium, more commonly know as horny goat weed, may also decrease symptoms of ED.  According to a study reported in the Journal of Urology, rats who received epimedium injections displayed an increase in penile blood pressure, which improved their ability to have an erection.  Researchers believe icariin, epimedium's active ingredient, increases nitric oxide levels, which improves erectile function.

Not all of Lexaryn's ingredients are proven to work, however.  Ashwagandha root, maca root, choline and bioperine have not been shown to improve ED symptoms in any clinical trials.

Is it Safe?: No.  Yohimbe bark can cause panic attacks, hallucinations, dizziness or changes in blood pressure.  Physicians do not recommend taking any supplements containing yohimbe bark if you have a history of heart, blood, or psychiatric problems.

Grade: C.  Lexaryn is definitely effective, but it also contains numerous side effects, including an increase in anxiety-like symptoms, such as panic attacks.  If you have any pre-existing heart, blood or psychiatric problems, Lexaryn will aggravate these conditions.  Speak with your physician before using this supplement to avoid additional side effects or contraindications.

Grade: A

What is Viswiss?
Viswiss is a herbal dietary supplement that claims to cure erectile dysfunction--a common sexual disorder that typically affects men over 50.  Viswiss incorporates a blend of ingredients designed to mimic the effects of Viagra and Cialis, but without its undesirable side effects.  Regular use supposedly makes it easier to have an erection by increasing testosterone and blood flow, key areas that typically decrease due to increased sexual dysfunction.  They also promise it works within 10 minutes to facilitate the erection process, making it one of the fastest working ED treatments on the market.

Ingredients: Viswiss contains yohimbe bark extract, epimedium, ashwagandha root, avena sativa, ginkgo biloba, Korean ginseng, maca, muira puama, saw palmetto, tribulus terrestris and l-arginine.

Does it Work?: It might.  Both yohimbine and l-arginine have been identified as potential treatments for ED in the medical community, due to overwhelming evidence showing it improves penile function.  The National Institutes of Health (NIH) gave

yohimbine a C for effectiveness, claiming it was shown to reduce symptoms of ED in numerous human trials.  Other studies suggest it also increases semen volume and may treat orgasmic dysfunction, or an inability to achieve an orgasm within a reasonable amount of time.

L-arginine has also been shown to reduce ED by increase nitric oxide production, one of the main components of achieving an erection.  There is also evidence l-arginine allows the body to release more hormones, which can heighten arousal and the sex drive.  Together, yohimbe bark and l-arginine may contain the right components to effectively treat ED.

But there is one problem with Viswiss, and it's a big one--both yohimbe and l-arginine are potentially dangerous.  There are numerous side effects associated with both ingredients, and may not be safe for a number of individuals.  Many physicians are hesitant to recommend it because of the increased risk for these side effects.

Is it Safe?: No.  Yohimbe bark can cause serious anxiety reactions, especially for men with pre-existing anxiety disorders.  Yohimbe also increases a man's risk for high blood pressure, increased heart rate, insomnia, panic attacks, hallucinations and dizziness.  Some physicians also report an increase in seizures and kidney failure.  

With L-arginine, some common symptoms include lung inflammation, which can worsen asthma symptoms.  There is also evidence it can disrupt blood pressure readings, and may worsen symptoms of genital herpes.  Both ingredients carry serious blood, heart and psychiatric risks, and should not be used by men with a psychiatric disorder, heart problems, blood pressure disorders, genital herpes or breathing difficulties.

Grade: C.  Although Viswiss may be an effective treatment for erectile dysfunction, it contains numerous side effects--some of which can be potentially life threatening.  Buy wisely: speak with your doctor before taking this supplement to avoid serious complications.

Grade: A

COBRA – One of the original natural male performance products. It is a product that must be taken for months before any real difference can be experienced. It has a nice base of top quality herbs that are good for overall male health, but it’s a formula that is outdated. Much new advancement has taken place since this product was created years ago.The Formula includes 11 herbs including Kola Nut, Oat Straw, Nettles, Muira Pauma, and Damiana. It can give someone with a slight energy or circulation problem a boost, but don’t expect dramatic results with this product. Some have said it’s like a wooden golf club, they were once the best around, but those days are long gone. GRADE C

What is Cobra?
Cobra is a all-natural male enhancement supplement containing muira puama, better known as Brazilian "potency wood", which improves sexual performance. Other ingredients, such as ginseng, also supposedly improve energy and endurance during lovemaking, reducing common sexual problems such as erectile dysfunction (ED) or premature ejaculation. Positive reviews from Amazon.com and GNC have made it one of the most popular male enhancement supplements available today.

Ingredients: Cobra contains kola nut, yohimbe bark extract, oatstraw, nettles leaf extract, eleuthero, horny goat weed, catuaba, muira puama, Korean ginseng, damiana leaf and saw palmetto.

Does it Work?: Yes—and it's effective. PDRHealth.com, a leading resource for physicians in the United States, lists muira puama as an effective treatment for erectile dysfunction (ED) and low libido, improving erection quality with regular use. It also contains anxiogenic properties, which increases energy levels quickly without causing any significant side effects.

Korean ginseng was also identified as an effective aid for ED in a study conducted by Sao Paulo University's Urological Division in Sao Paulo, Brazil. Taking Korean ginseng before intercourse improved erection quality, increasing the length of intercourse.

Don't leave out yohimbe bark extract either—it also contains an alkaloid called yohimbine, which helps reduce ED and a condition called orgasmic dysfunction, or an inability to orgasm while being sexually stimulated.

Is it Safe?: Not entirely. Yohimbe bark may cause high blood pressure, insomnia or skin flushing, making it potentially unsafe for people with heart or blood pressure conditions. It also increases a person's risk for panic attacks. There are few side effects associated with the rest of Cobra's ingredients.

Grade: B. Although it isn't as effective as Zyrexin, its ingredients are proven to attack ED at its core, making it easier to maintain an erection without additional physical stimulation. If you're looking for a great alternative to Zyrexin or Actra-RX, consider giving Cobra a try.

Grade: A

MAX AROUSE – On the bottle it reads “MaxArouse is an all natural blend created to enhance endurance, increase the body’s natural testosterone levels, and acts as a neuro-stimulator to increase sensitivity.” Sounds great, but it’s not the case. The main ingredient

ROPEX - This simple formula of flower pollen is trying to capitalize on the heavy marketing done for the product Ogoplex which talks about the alleged "Swedish Ropes" tall-tale that claims to provide a man with multiple orgasms. My European contacts have found zero evidence of any such "Ropes" legend in Sweden. It appears to be as real as Big Foot and the Loch Ness Monster. At the end of the day this is really a knock-off of something that is not too special to begin with. However, these guys did put 930mg of flower pollen in each serving while Ogoplex has only 400mg per serving. GRADE

Grade: A

V 4-MEN –This 14 ingredient formula from Georgia based Vitalabs has strong components along with a few that offset some of the benefits they provide.  Unfortunately it contains the hormone Androstenedione which was once thought to provide a boost in testosterone. But recent studies at Harvard commissioned by Major League Baseball have shown that this substance can actually increase estrogen in men. Estrogen is a female hormone and when men are exposed to high levels of estrogen they can develop fleshy breast tissue. Needless to say this androstenedione is not recommended. The product does contain 250mg of Yohimbe in extract form along with Tribulus Terrestris which have both been shown to make erections harder and last longer. Also present is the vasodilator L-Arginine at the very low level of 100mg per serving. L-Arginine is an excellent ingredient but at a dosage too low to provide any significant short term benefit for men taking this supplement. Survey responses have been a mixed bag with some men reporting an improvement in sexual performance and pleasure with some saying the tablets did nothing for them. None of the surveys have noted any increase in erection size at all. It has very little effect on erection size which is not too surprising given the formula. The company advertising slogan states “formulated for men to help them put the “howl” back into your sex drive.” Can it increase sex drive, - yes. Can it increase erection size, - no. This is just an average product. GRADE C

Grade: A

VirMax DS – This product with virtually zero advertising has managed to make its way onto the shelves at such drug store super powers as Walgreen’s and CVS. It’s almost like a private label product. Has all the standard herbs thought to improve sexual health, but the level are low. Lab results were extremely poor. Not an expensive product, but if it doesn’t work, who cares?

Grade: A

Natural Sex – This relic from the early 1990’s is still around. They were on the market 5 years before anyone ever even heard of Viagra. Back in the early 1990’s it was the only game in town and was very popular. Still sold by MLM companies, this formula is in desperate need of an update. So many advancements and discoveries have taken place, that now make this product obsolete. While marketers may says its sold millions of bottles, which it has, it sold them back when there was no competition. It can’t hold a candle to today’s cutting-edge products

AVOCET XL From the direct marketing wizards who call themselves Dixon Baird Urological Healthcare Sciences comes this bottle of smoke and mirrors. If you bought this, don't feel bad, the brochure was so slick and convincing that many people I know in the industry thought this was the Second Coming. It isn't. Very little scientific data behind the ingredients in the formula, which include cnidium monnieri and xanthoparmelia scabrosa.

Vital Erotic – Along with Horny Goat Weed and Stamina Rx, this product is one of the top three most widely distributed sexual supplements at convenience stores nationwide. Keep your money in your pocket on this one. Sell for under $2, but it doesn’t do much of anything. The lab report was not good, and therefore it’s impossible for it tow work well. Think of Papa John’s Pizza slogan – Better Ingredients, Better Pizza. Well here Poor Ingredients, Poor Product. Not very good.

SUPER MACHO – How is this for something sounding macho, the main ingredient
in this product is ground up bull testicles? Sounds like something Iron Mike Ditka must snack on. The bull testicles, better known as Bovine Orchic, has been reported to give men a jolt of testosterone, which theoretically can increase sexual performance. Orchic is best used as a complementary ingredient, as it is in some top products, but not as the star of the show. Best component of this product is that it does have 133% of the daily-recommended amount of vitamin E. However, there are better sources of vitamin E than Super Macho. GRADE D

HORNY TOAD - This product has to be someone's idea of a joke. I can't think of any other explanation, or maybe it is supposed to be sold to frogs or something? The ingredients make no sense. Maybe buy it as a funny gift to give somebody, but if you are looking to improve your sexual performance and pleasure, I wouldn't head out to the ballgame with this equipment. This would be like showing up at the first tee at Pebble Beach with a bag full of plastic clubs. GRADE S for silly

DAMIANA – Touted as a male intimacy formula is this product from Naturalife. Proprietary blend of herbs contains Foti, Ginseng, Sarsa-parilla, Licorice, Saw Palmetto, and Guto Cola in addition to Damiana. This is a group of run-of the-mill herbs if ever there was one. Long-term use will still leave most men feeling short changed. Damiana, along with maca, are two of the most over-rated and over-hyped sexual compounds. They may have been all the rage 25 years ago, but the benefits are so miniscule, you will be very disappointed. Responses on this product can be summed up in one word - disappointing.

MACA MAN – Remember all the hype surrounding the release of the movie The Godfather III? Everyone loved Godfather I & Godfather II, and expectations for the third in the series were high. All the build-up, all the anticipation, and the end result was a bad movie. The same is true of maca-based products. Manufacturers are touting maca like it’s the Babe Ruth of herbs and yet it’s a bust. To a tee every survey sheet we have received about maca products have been negative.

Grade: A

MACA MAGIC – Essentially pure Maca extract coupled with small amounts of Miura Puama, Catuaba and a few other herbs know to assist sexual performance. However Maca is the most over-hyped natural sexual herb other than Horny Goat Weed. You can look online and see all kinds of studies and antidotal stories praising the legendary benefits of Maca. Well these stories are incredibly exaggerated. I you look closely at the maca studies you’ll see they are very mis-leading. Small studies, no sophisticated testing, poor protocol, etc. Even at a super high extract maca doesn’t do much. At best, maca is a complimentary ingredient that can improve the effects of another ingredient if mixed in the proper ratios. But maca by itself is a dud.

T-Rx- From the same bozos that that lied to us about Magna Rx and Dr. Aguilar/Diaz (if you havne’t seen or scams exposed expose on Magna RX make sure you do. We sent our staff deep into Mexico to find the doctor used to perputrate that scam) . Touted as a testosterone booster, this product performed poorly in the lab – jut like Magna Rx. Their ads promise “earth shatter results” and “monsterous performance” but it simply isn’t the case. At the end of the day this is just a low-grade powdered formula that won’t do much of anything for you but take a few dollars out of your

What is Actra-RX?
Actra-RX is a sex supplement recently banned by the U.S. Food and Drug Administration (FDA) because it secretly contained sildenafil, the active ingredient in Viagra. Its website claims to treat erectile dysfunction naturally with Chinese herbs, extracts and stamina-inducing plant derivatives, improving sexual endurance and arousal. Its "results" supposedly appear in less than 30 minutes, lasting for up to 10 hours.

Ingredients: Actra-RX contains amino acids, Chinese herbs, Lycium fruit, Epimedium and cistanche.

Does it Work?: Yes—but only for men diagnosed with erectile dysfunction. Sildenafil increases cyclic guanosine monophosphate (cGMP) levels in the corpus cavernosum, the spongy matter inside the penis that causes an erection. This reduces the time between physical arousal and erection fullness, allowing men to engage in sexual intercourse at a faster rate.

Sildenafil does not improve arousal time in men not diagnosed with erectile dysfunction, however. According to a 2003 study reported in the International Journal of Impotence Research, sildenafil did not improve sexual function in sexually healthy men, including the speed of enabling an erection, sexual performance or the length of the penis. It was only shown to reduce the refractory time after intercourse.

Is it Safe?: No. In 2004, the FDA discovered Actra-RX contained 55mg of sildenafil, the main ingredient in Viagra, a erectile dysfunction drug. They advise consumers to stop taking or purchasing Actra-RX because of an increased risk of serious side effects, including a sudden drop in blood pressure.

They also warn it may cause significant—and sometimes deadly—contraindications with other prescription drugs, such as nitrates. People with diabetes, problems with blood pressure, heart disease or high cholesterol are also advised to avoid taking Actra-RX or any drugs containing sildenafil.

Grade: F. Actra-RX contains a powerful but potentially dangerous drug called sildenafil, which can cause life-threatening reactions. Actra-RX does not disclose this and continues to deny it contains this drug, despite being pulled from store shelves in 2004 by the FDA. It's not really all-natural or safe to take—in fact, it could harm your health. Actra-RX earns an F for its potentially dangerous side effects.

Boom – This chocolate powered mix was yanked from the market by the FDA because it is secretly laced with Viagra. Of course it worked, but we could tell something wasn’t right because after you take it you got a “medicine feel” in your body. It didn’t feel natural and many men reported getting dizzy and getting spots in their vision. It is still out on the market in some stores despite the FDA ban, so buyer beware, it can be very dangerous because it is not known exactly how much Viagra is in each pouch.

Grade: A

Nasutra – Also pulled off the market in both Canada and the United States for being laced with a Viagra analogue. Classic example of a Chinese supplier sending over a cheap synthetic chemical rather than an herbal extract. Remember, chemicals are much cheaper to manufacture than natural herbs. Nasutra, is no longer being sold, however there have been reports of some stores still selling out their inventory. Of course it worked, but it is potentially deadly since the amount of chemicals and other ingredients in the product is unknown. If you are an older man and taking an MAO inhibitor, or if you are supposed to avoid PDE 5 inhibitors like Viagra and you take a couple of Nasutra thinking it’s all-natural, you could end up dead. There have been many reports from hospital emergency rooms across the country of men being rushed in with heart attaches and seizures from taking herbal sexual supplements that secretly contain a drug like Viagra, Cialias or Levitra. Some Nasutra is still out there so watch out if you are at risk.

Vigor 25 – The guy behind this product go tossed in prison by the FDA for lacing it not just once, but two times with Viagra. His name is Michael Pang and he joins the list of about half a dozen people that have been sentenced to prison for selling sexual supplements. Pang, a Chinese national, saw his distribution of Vigor 25 explode mainly because og George Gordon his chief distributor, and the the guy behind Rize2The occasion – which was pulled of fthe market in 2008 by the FDA for being laced with Viagra. Check out our scam section for more on Gordon and the Rize2 scam. Vigor 25 is still occasionally found on EBay and in some stores, so beware if you have any kind of health issues – it is not a natural product, but is laced with a crude version of the same chemical used in Viagra.

Grade: A

VINAROL - One of the supplements that "turned up hot" for prescription drugs in laboratory testing conducted by the FDA. Like Super X, Vigor 25, and Male Power Plus and others, this product was discovered by the FDA to be secretly laced with the prescription drug Viagra. The FDA recalled 750,000 pills. The company claims it must have been an accident. Maybe. Anyway, if you still have any or you run across it, just know that it contains Viagra. I guess I'll give this one a V. GRADE V for Viagra
