SizeGenetics is made up of various components that are professionally integrated to give you maximum comfort and the best results.

The parts include the base ring, elongation bars, head piece and comfort strap.

How to Use SizeGenetics

Below are the steps to using SizeGenetics effectively:

  1. To begin with, set the device to the correct length using elongation bars. It is advisable to set to 1cm longer than your penis (in its flaccid state). For instance, if your penis is 6cm, set it to 7cm
  2. Put the base ring on your penis
  3. Fix the head piece onto elongation bars and place the head of the penis (glans) into the head piece
  4. Secure the penis in that position using the comfort strap
  5. Adjust the traction on the device using adjustment screws located next to the base ring (recommended traction set for beginners should be between 900 and 1500 grams)
  6. Do not change the traction until 6th week (by then your penis will be used to the device and you will be able to adjust as you wish)

Why Should You Trust SizeGenetics ?

There are hundreds of companies manufacturing and distributing penis enlargement devices but none of them comes close to SizeGenetics official manufacturer in regards to quality and customer satisfaction.

Also keep in mind that there are scammers purporting to sell genuine SizeGenetics extenders only to deliver low-quality equipment.

Thus it is advisable to always buy SizeGenetics from the official manufacturer.

Here are some of the reasons why SizeGenetics is the best penis extender on the market:

  • It is Clinically Proven

Seasoned specialist in general and plastic surgery such as DR. Finn Knudsen recommends SizeGenetics for treating penile curvature and other disorders such as penis shrinkage.

Many other doctors in the field of plastic surgery have tested and approved the device for use by anyone who wishes to increase their penis girth and length.

  • Backed By Authentic Medical Certificate

Permenda LTD is licensed to manufacture and distribute SizeGenetics extenders and they have an authentic medical certificate which gives them a competitive edge. They also adhere to the required manufacturing practices which make them more trusted and loved by customers.

  • It is Backed By Scientific Studies

Studies recommend extenders such as SizeGenetics as the ideal option for lengthening penis size.

In a study published in the National Library of Medicine (NLM) to determine the effects of penis extenders on penile growth and girth, it was shown that wearing the device for at least 6 months results in significant increase in penile shaft length and some mild increment in girth. [1]

Thus, penis extenders are backed by scientific research as the best non-invasive penis enlargement alternative to dietary pills, vacuum pumps, prescription medications and surgery.

Does Really SizeGenetics Work?

Does Sizegenetics work

Scientific research together with the numerous customer testimonials available online and offline proves beyond reasonable doubt that SizeGenetics extender actually works.

However, results are not achievable overnight and you need to exercise patience for you to attain significant gains.

The minimum recommended time is 6+ months meaning you’d be wasting your time and money if you order SizeGentics with the intention of getting quick results.

How it Works        

SizeGenetics works in a similar manner to bodybuilding exercises, meaning that it stretches your penile muscle tissues resulting to cell duplication. [2]

As the body tries to counter the strain caused by traction, new cells grow through cell division, which in turn increase the length and girth of the penis.

The main cells targeted by traction equipment such as SizeGenetics are those located at the corpora cavernosum (the spongy tissue that holds blood during erection) to ensure that your manhood can hold more blood for a harder, sustainable erection.

SizeGenetics Side Effects

For the 17+ years that SizeGenetics has been on the market, no single side effect has ever been reported. However, keep in mind that the stretching process can be moderately uncomfortable at the beginning before you become accustomed to the device.

Where to Buy SizeGenetics

Genuine SizeGenetics device is only available on the official website. As earlier, mentioned, there are thousands of companies out there who sell fake SizeGenetics devices and you should be wary of them.

Some people believe that eBay, Walmart, Amazon and other large scale commercial stores are the best for buying SizeGenetics but this is a huge misconception since counterfeit products also find their way into these commercial stores.

Hence, the only way to avoid getting scammed is to order from the official website.

SizeGenetics Reviews by Customers

There are thousands of customer reviews both online and offline. In our quest to find out what real users have to say, we dug deeper into forums such as reddit, pharmacy forums etc. We also sampled customer reviews on social media in addition to interviewing some users face to face.

Our findings were quite impressive. We noted that most of the reviews were rated between 4.5 and 5 stars. The feedback we received from our interviews also persuaded us into believing that Sizegenetics actually works as advertised.

Another point we also noted is that results can take quite some time for some people (up to 2 years in some cases) hence patience is vital when using sizeGenetics.
