Endowmax, Xytomax, Xanogen, Natural Gain Plus, and Vimax

Review - Penis Enlargement
Endowmax was the most effective penis enlargement pill of the group. Endowmax effectively increase penis length, girth and firmness. The testers that used Endowmax experienced and average of 28% increase in size translating into on average 2 inches in size. They also experienced a marked improvement in sexual performance. We gave Endowmax a must buy recommendation.
Xytomax penis enlargement pills
Xytomax increased the length and girth for most of our testers. Our testers reported harder, longer-lasting erections, giving them a boost in sexual performance. Users of Xytomax noted a marked increase in libido. We rated Xytomax a must buy.
Xanogen penis enlargement pills
Xanogen turned out to be a great sexual enhancer, producing excellent erections for almost all of our testers and their sexual appetite increased as a result. Xanogen's average 1 inch increase in size was not satisfactory to our testers, so we gave it a tentative buy.
natural gain plus penis enlargement
Natural Gain Plus was one of the more expensive products of the group but it did have some interesting properties. Our testers experienced about a 1/2 inch growth which was respectable but not the kind of significant growth most of our testers desired.
Vimax came in last because some of our testers did not achieve any sexual enhancement results or penis size increases. However, about 50% of the test group did achieve about a 1/2 inch growth in size. So apparently this formula was effective but it was hit or miss depending on the user.

Endowmax was by far the most effective penis enlargement pill of the group. It effectively increase penis length, girth and firmness for all testers. On average, the testers that used Endowmax experienced an average of 28% increase in size -- that's a 2 inch increase on average.

Testers also reported a marked increase in sexual performance. This is by its very nature much more difficult to measure with numbers, so instead we'll directly report the words of one of our testers: "My girlfriend had to beg me to stop. And that's never happened before." All of our testers agreed on this point - erections were harder, bigger, easier to achieve and lasted much longer.

Staff and testers alike were impressed with the effectiveness of the Endowmax formula. Even more surprising, the increase in penis size with Endowmax is permanent. None of our testers reported side effects.

We rated Endowmax a must buy with 96%. Visit www.endowmax.com.


Xytomax contains proven male enhancement ingredients such as Catuaba, Epimedium (Horny Goat Weed), Muira Puama and more. Our testers using Xytomax experienced an average of an inch of penis growth.

Many of our testers reported a definite boost in sexual performance, as well. Their erections were harder and stronger, and lasted longer. Additionally, our testers noted a marked increase in libido. We attribute this to the use of Yohimbe in Xytomax's formula. Yohimbe is only one of four products approved by the FDA for Erectile Dysfunction, the other three being the prescription drugs Viagra, Cialis, and Levitra. We think the addition of Yohimbe can be attributed to the slightly higher cost of Xytomax - but you get what you pay for!

The Xanogen formula is similar to others we tested and produced somewhat successful results.

On average, our testers reported approximately 1 of an inch increase in penis size. Most men reported a mild increase in sexual appetite but not as dramatic a change as those who tried Xytomax or Endowmax.

Xanogen increases the blood flow to the penis erectile tissues and to the two spongy areas (called the corpora cavernosa) on either side of the penis. When you get aroused blood flows to these areas; when you get aroused and you are using Xanogen, much more blood flows to these areas, thus giving you firmer, larger and more vigorous erections.

Considering that Xanogen is priced about the same as its better-performing competitors, we give Xanogen a tentative buy rating. Visit www.xanogen.com

Natural Gain Plus

Natural Gain Plus contains similar ingredients - a combination of herbs, L-Arginine and Zinc Gluconate.

Our testers experienced about a 1 inch growth in penis size, which is definitely worthwhile, but not exceptional. This penis size increase occurred very slowly over the 3-month test period. Testers didn't realize their penis size was increasing until they were measured.

On the upside, almost all testers reported an increase in desire and in sexual performance. Natural Gain Plus seem to be more effective in increasing libido and sexual desire than in increasing penis size. No unpleasant side effects were reported.

According to our trials, Natural Gain Plus does increase penis size (not by very much), and they work slowly. They do perform well as an aphrodisiac. We give Natural Gain Plus a tentative buy rating. Visit Natural Gain Plus website.


Vimax came in last because 55% of our testers reported no increase in penis size or in sexual desire. Among the other 45% of testers, an average of 1/2 inch increase was recorded, and the 45% minority also reported a mild increase in desire.

Vimax has similar ingredients to the other formulas tested. We speculate that some part of the preparation process, or perhaps an interaction between ingredients, is responsible for this unreliability. In addition, differences in body chemistry between men could account for the difference in results.

In any event, Vimax performed the least well of the penis enlargement products tested. Due to its erratic effectiveness, we give Vimax a do not buy recommendation.
