Methandrostenolone/Methandienone (Dianabol) is used for physique and performance enhancing purposes by competitive athletes, bodybuilders and powerlifters. It is said to be the most widely used ASA for these purposes today and in the past. Methandrostenolone/Methandienone (Dianabol) binds to the androgen receptor and activates it to exert its effects. These include dramatic increases in protein synthesis, glycogenolysis and muscle strength over a short period of time.
