Not many extenders have a doctor’s guarantee behind them. The SizeGenetics is actually prescribed to patients in Europe to naturally extend the penis. I have seen unreal results with this device and it is hands down the best on the market. It is the first male enhancement device I owned back in 2012 and they have continued to make constant improvements.

***UPDATE 2017***

This review was done after 6 months experience using the SizeGenetics in the latter half of 2011/early part of 2012. Although it has been a while since I have used the SizeGenetics I still stand by the product and what it has done for my penis size and confidence. For those of you with Peyronie’s disease, you can read both my comprehensive guide to Peyronie’s disease, as well read my review on the new Peyronie’s Device.

My Original SizeGenetics Review

I started this blog halfway through my experience using the SizeGenetics extender, about the beginning of January 2012. I primarily wanted to use it as a space to document my progress but it eventually gathered a small audience and it turned into what it is today. So let’s get into the product that started it all in this SizeGenetics review:

What is the SizeGenetics?

The SizeGenetics is a traction device that attaches to the head of your penis and lightly stretches it away from your body for extended periods of time. This over time triggers a process called cell division and forces your penis to grow longer. The SizeGenetics is backed by clinical studies and is prescribed to patients with Peyronie’s disease (curvature of the penis) and to those who want to increase the length of their penis. The SizeGenetics was the first penis extender on the market that was backed by clinical studies, and is constantly being upgraded and refined by a team of medical professionals.

When I did my initial research through extenders, I looked at the SizeGenetics, X4 Labs, and Jes Extender (all which I would eventually test and review), but I settled on the SizeGenetics to help me increase my penis length before I started this website.

How Did I Get My SizeGenetics For Free?

As I was looking through the official sizegenetics website, I came across a promotion that was advertising a free extender. I’ll get right into the terms and conditions. When you buy the SizeGenetics and use it for 6 months while following the instructions, you will see noticeable size gains.

If you take a before and after picture and send it in to the SizeGenetics headquarters they will completely refund your purchase – which makes your extender completely FREE! This is exactly what I ended up doing – I essentially gained 1 inch for free. The best part is, is that there is a 6 month satisfaction guarantee for the SizeGenetics, so even if you aren’t seeing gains (you will) you can send it back and receive a full refund – no questions asked!

Why Choose SizeGenetics Over Another Brand?

First of all, you can get $50 off the SizeGenetics through this link. Not many other extenders offer value like that.

And as I mentioned above, I’ve tested at least 10 different penis extenders, and while some have their merit, SizeGenetics comes out on top for a variety of reasons:

  • SizeGenetics is HANDS DOWN the most comfortale device on the market
  • It has a patented 16 way comfort system
  • It can be worn at many angles, which enables you to wear it under your pants throughout the day
  • Includes other bonuses, such as traction powder (for no-slip grip), lotion, and wipes
  • The entire package comes with a premium Penis Health DVD which features exercises for a bigger penis
  • Has an unreal 180 day money back guarantee
  • FREE SHIPPING throughout the US (1-2 days)
  • It was the first extender to have clinical studies backing the product
  • Great for the treatment of Peyronie’s disease
My Experience Using the SizeGenetics Extender

I used the SizeGenetics for 6 months in total. In that time I gained 1.2 inches in length, and .5 inches in girth. It definitely takes some getting used to when you first start wearing it. If you have had braces I can compare it to that, annoying at first, but then you don’t even notice it is there. It is a big commitment to start wearing this device. It is recommended that you wear it 6-8 hours per day, but I got away with wearing 4-5 hours per day. It all depends on how fast you want to see results, and what kind of results you would like to see. If you notice my numbers, I had minimal girth increases, but an amazing length increase in my flaccid size. You will see girth increases with pumps such as the Penomet or the Bathmate. It was a great experience and the SizeGenetics really delivered.

Make sure to watch the video at the top of this article for my full instructions on how to wear the device, how to extend the device, and my instructions on how to use it.

A quick side note, aside from my testimonial and experience using the SizeGenetics on this website, you can check out a stream of constantly updated user testimonials on the official SizeGenetics website. These are guys who submitted their before and after pictures and received the device completely free! Check it out here:


In my opinion, SizeGenetics is the best extender pick you can make, and is my number one choice based on its durability, effectiveness, and the results that I have seen from using it. There are many other extenders that look like the SizeGenetics but are in fact later renditions that copy the original system. It is a little expensive at around $389.00 dollars for the complete system, but also keep in mind that it is an investment in your self-confidence and you have the opportunity to receive a full refund at the end of your 6 months by taking before and after pictures. Their penis health DVD exercise program is top notch and you will definitely start seeing results around the 2-3 month mark from using the SizeGenetics extender. I would also recommend supplementing alongside this extender, you can look in my top 3 supplement review section for my top picks.
