Top Questions About SizeGenetics

Not sure if SizeGenetics is right for you?
Check out some of the frequently asked questions we get asked!

  • ?

    Does the SizeGenetics hurt? Is wearing the SizeGenetics uncomfortable? Actually it does not hurt at all, it actually feels a little weird at first but within a day or two you get used to it and it is quite comfortable to wear over a long period of time – by no means does it hurt.

  • ?

    Do you have to wear the SizeGenetics for a long time? The short answer is yes. The included instruction manual recommends that you should wear the device for approximately 6-12 hours every day, however results can be achieved with just 4 to 6 hours usage per day. For optimal gains we recommend you wear SizeGenetics for at least 5 days per week for 4 – 6 months for optimum penis length gains.

  • ?

    When You Use the SizeGenetics for a Long Time, Are the Results Permanent? Absolutely, however the results you achieve in terms of actual length and girth gained will depend entirely on how dedicated you are to the program and how regularly you use your SizeGentics device.

  • ?

    Is it beneficial to supplement with something like TestoZone while you are using the SizeGenetics for length gains? The answer to this is absolutely YES. Think of it like a bodybuilder – when he is done his workouts he uses supplements to help solidify his gains, the same thing applies with the SizeGenetics or other extender devices. The likes of TestoZone aren't essential to your gains however can improve your ability to achieve gains in length, girth and sexual confidence.

  • I started using your traction device in late February. At that time my erections measured at 6”. After the first month I noticed an increase in blood flow. Now 4 months later, I have gained 1” on my erect measurements! I’m completely satisfied with your product and will continue to use to get even more gains!

  • After four months of use, I am amazed by the results. Even my wife is please, as she smiled and hugged me upon seeing my most recent measurements. Starting the program, my measurement were a erect length of 4.4 inches and erect girth of 4.3 inches. My current measurements are now a erect length of 6.5 inches, and erect girth of 5.0 inches.

  • I could not believe my eyes! I am 30 years old and had always felt that my erection size was below average. I tried various devices in the part and none of them really worked until I came across the Size Genetics penis enlarger. After only a couple of weeks I noticed that my erections were a lot harder and stronger. My orgasms were more intense and overall my sex life was more enjoyable.

  • I noticed a shocking ½ inch gain after the first two weeks! I continued using the device and even though my gains did not continue at that pace, I began to see regular gains at the average rate seen by the studies on the SizeGenetics website. By the end of 4 months I have gained a full inch in my erect state and now sit at 6”, I am excited to see how far I can go with this device!
