I don’t know much about it except for the fact that it sounds like it has the potential to be a good PE supplement. Apparently, since injecting T reduces the human body’s collagen synthesis by anywhere from 50 - 80 percent, many people take this supplement instead. I have read that it increases the body’s ability to produce collagen, but at the same time weakens the integrity of collagen cross-linking. This would make the tissues stretch/tear more easily. Furthermore, the tears would be filled in with collagen more quickly (being that synthesis is up) and probably with more healthy collagen cells. Has anyone used Winstrol (or a similar supplement) while doing PE? Even if noone has ever used (or heard of) this particular supplement, I am open to opinions as to whether or not it would be good for PE.
