The most extreme but safe device on the market

10935-tension-animation

SizeGenetics™ is the most extreme but safe penis enlargement device on the market today. With a massive 2,800 grams of tension, our team have pushed traction technology to new limits, bringing you the most effective results possible.

Devices with a higher tension give you better results, and our scientists from Denmark and the USA have developed a penis extender that gives you more tension, and bigger and better results than any other product available.

We couldn’t push tension higher even if we wanted, because your safety is our priority. Unlike products manufactured in China, our strict production standards mean our traction devices are safe for you to use, allowing you to enlarge your penis with complete confidence and peace of mind.

Don’t risk damaging your penis with inferior extenders claiming tension over 2,000g imported from sub-standard Chinese manufacturers.

SizeGenetics™ has undergone years of evolution and ongoing research and development to bring you the most extreme but safe device – meaning you can trust the SizeGenetics™ extender to safely and effectively enlarge your penis by inches.
