Natural Male Enhancement, Enlargement & Impotence Products

You May Be Shocked At What We Found in our Review of Advogain & Zenerx!

There are several herbal ED cures on the market that contain ingredients that have been shown to work like Viagra and have long term positive effects on all aspects of a mans sexual health.

The positive benefits natural herbal supplements provide by increasing erection ability, size, and fullness, as well as treating impotence, are many. They can include bigger, stronger erections, greater sexual performance, increased libido, and better overall health.

There are many male enhancement/impotence products on the market, but buyers should beware of formulations that use potentially hazardous ingredients and manufacturers that do not honor product guarantees (see review criteria for details).

In this review, we examined two of the most popular herbal male enhancement/impotence products: Advogain and Zenerx.

Zenerx: Recommended - Click For Zenerx Information

Advogain: No Recommendation (Unable to verify business entity) - The ingredients in Advogain are safe and several demonstrate a positive effect on male performance. However, we were unable to identify the business entity to undertake a business check. They do not provide an address or phone number, and the ownership of the domain advogain.com was concealed. It appears that they have made a mis-leading representation of having 1.5 million customers which we believe is doubtful based on other facts.

Safe, Effective Herbal Ingredients

Our review only included ingredients where we found multiple scientific studies vs. anecdotal evidence to support it's positive effect on functions that are important to producing a strong, full erection, increased libido, and to treat impotence issues. This is not to say that other herbs are not effective, only that we have research backing those listed.

Shilajit (Viagra effect)

The anti-stress and adjuvant effects of Shilajit have been evaluated in numerous Indian studies. Shilajit provides an anti-oxidant defense against several reactive oxygen types. Processed Shilajit provides complete protection to methacrylate against hydroxyl radical-induced polymerization, and acts as a reversible nitric oxide-captodative agent. These findings are consistent with therapeutic uses of Shilajit as an ayurvedic (rejuvenator) against oxidative stress and geriatric complaints of erectile dysfunction.

Horny Goat Weed (Viagra effect)

Horny goat weed has been used for over 2000 years as a sexual and reproductive tonic. It acts to increase erection ability, size, and fullness.

Horny goat weed contains a flavonoid called icariin. Icariin is a cGMP-specific PDE5 inhibitor like Viagra, Cialis and Levitra, as demonstrated in a 1984 University of Peking study.

It also functions as an adaptogen by increasing levels of epinephrine, norepinephrine, serotonin, and dopamine when they are low-promoting energy-but reduces cortisol levels when elevated (an anti-stress effect), which causes fatigue and depresses sex drive.

Finally, horny goat weed can restore low levels of both testosterone and thyroid hormone back to normal, improving sex drive. 

Muira Puama

This South American herb has been used for centuries to treat weak libido and erectile dysfunction. Two recent French studies supported it's effect on impotence.

In one study of men treated with muira puama extract, 62% reported it had a dynamic effect on their libido, while 51% with erectile dysfunction said that it was beneficial to their treatment.

In a second study, muira puama extract was given to 100 men with sexual asthenia. Of these, 85% reported an increased libido, while 90% reported an increased ability to maintain erection.

Allium Sativum - Garlic (Viagra effect)

Yes, good old garlic. In two different 1998 studies-one from the National University of Mexico and another from the Institute of Pharmacology, Toxicology and Pharmacy in Munich, Germany-garlic was shown to "activate nitric oxide synthase", or enhance the nervous system's ability to react to nitric oxide.

Also, there are multiple studies compiled by the Sloan-Kettering Cancer Institute demonstrating garlic’s aid in preventing and having curative effects on several medical conditions which often cause ED. These conditions include high blood pressure, heart disease, hypertension and atherosclerosis.

Mucuna Pruriens

Mucuna pruriens works as a prolactin inhibitor, a growth hormone stimulant, and to increase testosterone.

A US patent was filed in 2002 on the use of mucuna pruriens to stimulate the release of growth hormone in humans. High levels of l-dopa in the mucuna seed are converted to dopamine, which stimulates the release of growth hormone by the pituitary gland. L-dopa and dopamine are effective prolactin inhibitors.

Increased levels of prolactin are considered responsible for 70% of erection failure in men. In one study, ingestion of the seeds in 56 males improved erection, duration of coitus, and post-coital satisfaction after four weeks of treatment. It also promotes spermatogenic effects in men, improving sperm count and motility.

Tribulus Terrestris

Tribulus is a natural testosterone enhancer. It is also said to be an excellent circulatory system tonic, and can help build muscles and strength.

Clinical studies on the sexual activity-enhancing effect of tribulus have shown it to contain protodioscin, a saponin constituent, improving libido in men with impotence due to various causes, libido in women with menopausal symptoms, and sperm motility in infertile and subfertile men.

In another study involving 59 men, ages 22-67 and suffering from a range of sexual dysfunctions, an increase in sexual desire and fantasies, as well as sexual self-confidence, was reported in almost all patients. The subjective experience of pleasure, joy and satisfaction was reported in 80%, erection improved in over 75%, and the duration of intercourse before ejaculation was prolonged in 25%.

Ashwagandha

Here is what the Sloan-Kettering Cancer Center said in their Ashwagandha Clinical Summary:

"It (Ashwagandha) is also used as a general tonic, to increase energy and improve health and longevity...  Ashwagandha has shown...antioxidant effects in the brain and...a tranquilizing effect on the central nervous system in animals...human studies suggest Ashwagandha may promote growth in children and improve hemoglobin concentration, red blood cell count, and sexual performance in adults"

Non-Herbal Ingredients

Zenerx does not contain additives.

Advogain contains the following additives: Dicalcium phosphate, stearic acid, croscarmellose sodium, magnesium stearate, silica and film coat (hypromellose, hydroxypropyl cellulose, polyethylene glycol, titanium dioxide, propylene glycol, and FD&C blue #2 lake).

Herbal Ingredients for Overall Health & Help ED Conditions

There are multiple causes of impotence and low sex drive, ranging from mild (low sex drive, weak erections, lack of energy, slow and weak ejaculation) to severe (total inability to achieve erection and complete lack of sexual desire).

These causes can be:

• Cardiovascular (i.e. restricted blood flow, high blood pressure, heart disease, hypertension, and atherosclerosis)
• Renal or urological
• Nutritional (i.e. malnutrition, vitamin or mineral deficiency)
• Endocrine (i.e. low testosterone or high prolactin)
• Neurological
• Muscular & tissue-related
• Psychological (i.e. stress, anxiety, etc.

Potentially Dangerous Ingredients

We reviewed the ingredients in each supplement and cross-checked the ingredients against ingredients identified by the FDA as "Supplement Ingredients With Concerns".

The one common ingredient on this list is Yohimbe, which is considered dangerous and is an ingredient in a number of male enhancement/impotence products on the market.

Our recommendation is to avoid any product containing Yohimbe. There are many other alternative ingredients that have proven effective and are safe.

Neither Advogain nor Zenerx contain Yohimbe or any other FDA "Supplement Ingredients With Concerns".

While the ingredients contained in both supplements are considered safe,  individuals may have different reactions to the ingredients just like with food.

Other Factors

Product Guarantee

It is important that manufacturers stand behind their product with a money-back guarantee. The fact is each individual is different, and some formulations may work better than others for conditions that may cause impotence, small, or weak erections. That's why a 100% guarantee is a must and the manufacturer must follow through with that guarantee.

Made in The United States

By purchasing from companies that only manufacture in the US, you ensure that ingredients are as labeled. Most supplements with other medicinal or non-herbal substances added (such as sildenafil citrate) have been manufactured outside of the US by questionable companies

Check to make sure that the supplement is manufactured in the US and is not sold by a US company importing from abroad. The Vinarol recall is a recent example of this practice.

Known Better Business Bureau Complaints

We checked to see if there are any known product complaints or recalls registered with the Better Business Bureau for each of the products reviewed.

We where unable to determine if there are any complaints against Advogain. This is because we could not find out who the business entity is. There is no listed street address, business entity name, phone number, or email address. The owner of the domain name advogain.com is concealed. The level of Advogain's secrecy is a concern.

Zenerx had no complaints filed with the Better Business Bureau.

Known FDA Complaints or Recall for the Specific Product

We checked to see if there are any known product complaints or recalls registered with the FDA for each of the products reviewed.

No FDA complaints or recalls were found for either product.

Potentially Misleading Claims

Because we expect companies to shine a positive light on their product, we give them the benefit of the doubt on subjective information. Because every individual is different, results of any herbal supplement or pharmaceutical will vary. That's why our review focuses on proven ingredients. However, if a claim is made that is clearly misleading based on factual evidence, it is considered a potentially misleading statement.

We could not verify that Advogain has "1.5 million customers", and it seems unlikely they do. For example, the domain was registered in July 2003, and we are surprised that a company that goes to such lengths to conceal their identity and provides no customer service phone number or address could have that many customers.

Recommendations

While both products include ingredients shown effective at increasing erection ability, size, firmness and aid impotence, we can not recommend Advogain because they do not honor their guarantee by refunding customers' money.

In this review, we only recommend Zenerx.
