There is honestly no need for such a vast argument on this topic. Forget psyhcological wise aspect, the main side is the medical side. And from a medical aspect, there's a clear reason to why aas is harsher on "MEN" under the age of 25.
Firstly we need to understand what test really is. Tetosterone is the hormone that is "MOST" important in the development of testis, prostate, muscle growth, bone mass, and the growth of body hair. All these growing organisms need NOT to be altered for a normal growth. Now understand, that the testosterone level is at its peak from ages 18-23. It becomes average as the growth stops which in most men is around the age of 25. While the testosterone is at its peak, the last thing you want to do is alter with it and permanently affect your growing tissues. You may regain your test level back in later years, but by using aas early, you will lose that peak stage which will, medically proven, affect your overall growth by 8%.
And for the guy saying he used aas at 17 lol, remember, every body type is different and aas is honestly like Russian roulette. 3 may survive with minimal effects, but the 4th one will regret it for a lifetime.
