Typically, any athlete who tests positive for banned substances after having served a previous ban receives a lifetime ban from the sport of athletics. Many high-profile sportspeople to receive doping bans have come from the sport of athletics, with significant past cases concerning Ben Johnson , Marion Jones and Tim Montgomery . Furthermore, a number of athletes who underwent state-sponsored doping programmes in East Germany between the 1960s and 1980s were competitors in athletics, but the quality of the international anti-doping work was so poor that only one East German athlete ever tested positive.  Following allegations of state-sponsored doping in Russia , the IAAF suspended the country's athletes from competition, including the 2016 Summer Olympics.

All steroids can elevate liver enzymes but levels usually return to normal once the cycle is stopped.

This steroid tends to be used because large gains in muscle mass are seen in very short periods. Methandrostenolone ( Dianabol ) shares this side-effect profile in both its oral and injectable forms. Testosterone enanthate and testosterone propionate are also toxic.
