100% guaranteed penis enlargement! SizeGenetics™ promises you safe, fast gains or your money back with our double money back guarantee!

Guaranteed to work for you or your money back!

SizeGenetics™ removes all the risk from buying a penis enlargement device. It’s been clinically tested and proven to work, so you can purchase with full confidence that SizeGenetics™ will extend your penis safely and effectively.

Our double money back guarantee promises that your SizeGenetics™ will work for you or we’ll refund you your full purchase price. You’ve got nothing to lose, and everything to gain!

SizeGenetics™ guarantees:

  • Your safety – Our penis extenders have been clinically tested and have been certified as a medical type one device. Use SizeGenetics™ as instructed and you should never experience an injury.
  • High quality – Don’t settle for a cheaper, inferior device that can at best, break during use and cost you a small fortune in spare parts, or at worst, seriously injure your penis. SizeGenetics™ is manufactured to the highest standards using the finest quality materials, and every single device must pass our strict quality testing before it is allowed to be sold.
  • Penis Extension – We firmly believe that SizeGenetics™ is the most effective penis extender device available on the market. We are backed by clinical testing, doctor endorsements, years of research and real user testimonials, proving that it can work for everyone, including you!

You’ll find our double money back guarantee really simple, because we believe 100% that SizeGenetics™ will work for you.

Simply use the SizeGenetics™ device for 120 consecutive days (4 months). In the unlikely event that you don’t see any gains, get in touch with us to request your refund and to return your device.

Why do you need to use your device for 4 months? While many of our customers begin to see gains within the very first few weeks, the speed of results vary from person to person. By using the SizeGenetics™ device for 4 months, you’ll be allowing sufficient time for the device to work for you. To qualify we will need to see some documentation – i.e. pictures before/after, while wearing the device, and a log with the number of hours and amount of traction.

Choosing SizeGenetics™ is risk free – we guarantee you will extend your penis length (quickly and safely) or you’ll get double your money back!
