Does Jes Extender Work? Full-Review

We tested Jes Extender and the results will surprise you!

Like SizeGenetics, Jes is a non-surgical penis enlargement device that uses the principle of traction to promote growth. This is one of the first devices introduced to the market.

SizeGenetics works by exploiting the ability of the body’s cells to grow and other tissues to expand and reproduce when they’re under tension.

Frequently Asked Questions

What is it, and how does it work?

It is a medical penis enlargement device. It uses the bodies’ natural response to traction, by creating new tissue cells. Used as your personal training device it increases your length AS WELL as your girth.

Does this work for all men, having all sizes to begin with?

Yes. The device will fit sizes from 1.5-8.5 inches in the stretched flaccid state.

Can SizeGenetics be worn at work and while you sleep?

If you have a non-physical job, the penis extender can be worn under boxer shorts and loose fitting trousers – helping you to achieve a bigger penis all day long. It can perhaps prove difficult to keep on during sleep if you twist and turn a lot. The only way to determine this is by trying.

How long can it get, and are the results permanent?

In theory you will continue getting results from continued use. We are not aware of any maximum, but some very patient users have more than doubled their size. Your results will stay the same after stopping the use, since the new cells created will stay around in any event.

Do you guarantee that it works for me?

Yes, if you after diligent, documented use haven’t achieved any results, we offer a money back guarantee.

Is billing and shipping discreet?

We take our customer’s privacy very seriously. That’s why every Jes Extender product is shipped in an anonymous package by a major shipping courier. We guarantee that we will ship your Jes Extender product in a completely unmarked and plain box with nothing but your address printed on the outside. We know that penis enlargement is a personal topic and we’ll make sure you can keep it that way.


The Jes Extender is one of the best selling penis stretchers on the market and is highly recommended if you are considering a penis stretching device. The Jes Extender system is crafted from quality materials. Considerable thought has been taken with everything from the design of the device to the packaging of the product itself.

Overall, Jes Extender is a high quality system that provides the results it claims. However, after fully testing the various components of the Size Genetics systems, we recommend that you purchase the Gold Edition in order to receive the best value for your money.
