Androstanolone is identical to the body's own dihydrotestosterone which, as we know, is formed by the peripheral conversion of testosterone. Some therefore call Androstanolone a synthetic d1hydrotestosterone. This steroid has a predominantly androgenic effect and, due to its structure, cannot be converted into estrogen. For a fast buildup of power and muscle mass Androstanolone is of little value.
It used to be the athlete's favorite competition steroid since it helped to obtain a harder muscle through a lower fat content by increasing the androgen level without aro-matizing. Numerous athletes used Androstanolone during work-outs for dopingtested championships since the substance remains in the body for only a short time and the testosterone/epitestosterone value is not influenced.
Another positive characteristic is that the injectable version is not liver-toxic. Today, however, Androstanolone is rarely used by athletes. One reason for this is that almost all European and American compounds are no longer commercially available. The other reason is that most athletes use the still readily available Masteron which has similar effects. Neither the original nor a fake of Androstanolone is available on the black market.
