Extenz Overview

Extenz is a product made especially for men who are dissatisfied with the size of their penis. It claims to have a 97% success rate in enabling men to support their penis size by several inches while also improving the quality of their overall sexual performance. There are a number of websites with information about Extenz, which is manufactured by Innovative Netraceuticals. The official site contains sections with FAQ’s and customer testimonials and a brief explanation of how the product works. Despite the statistics showing how well Extenz works, there are no actual clinical studies published, just a ‘month by month’ description of what the user can expect.

Extenz is slightly less expensive than many products of this type, costing $33.50 when purchased from the site. There is a money back guarantee offered but no further details or terms are shown.

Extenz Product Description


The only active ingredient contained in the Extenz formula is a substance called Siales which was developed by Innovative Netraceuticals. According to the information, this ingredient helps support the blood flow to the penile chambers, resulting in fast and permanent growth. Unfortunately the manufacturer will not say exactly what Siales is comprised of, apart from the fact that it is all-natural. Other ingredients listed include Yohimbe, Horny Goat Weed and Ginkgo Biloba which are also ‘active’ but for which no explanation is made.

Extenz only requires one capsule per day, preferably taken in the morning.

Good About Extenz

  • Customer testimonials are shown for Extenz
  • Results are said to be permanent
  • The ordering process is secure
  • Siales is a natural substance
  • All other ingredients are listed

Bad About Extenz

  • Company contact details are limited
  • The Siales formula is not disclosed
  • The guarantee details are not shown
  • No free samples are offered

Extenz the Bottom Line

Why the manufacturer of Extenz will not be upfront about the key active ingredient Siales is not known, especially if it does work as well as they claim. Additionally, it is doubtful as to whether the results of using Extenz are really permanent – while the support in blood flow will help support the size of the penis while erect, no product really has the ability to cause a long-term growth.

With countless male enhancement supplements available on the market today it seems impossible to find “the right one.” Sexual performance declines naturally as men age, which may contribute to feelings of inadequacy or embarrassment. Male enhancement supplements should be based on four key factors: active ingredients, ability to support sexual stamina, enhance arousal, improved* sexual desire, and backed by clinical studies.

Below you’ll find some of the most effective male enhancement supplements on the market today, in our opinion.
