Size Genetics

4.5/5

SizeGenetics Review:

One of its main advantages is that it is discreet and it comes with the whole package that you need to start your male enhancement journey.

SizeGenetics is an extender that applies tension to the penis. It works in the same way as the Phallosan Forte but instead of a vacuum mechanism, it uses a strap at the head of the penis and two parallel adjustable bars that run parallel to the shaft of the penis.
