[QUOTE=Leisesturm;14181553]Out of competition? How do they possibly enforce this? My testosterone tests squarely in the normal range, what would an official use as evidence of doping to disqualify me from competing in a race?[QUOTE=Hermes;14181253]

Urine or blood is tested for synthetic testosterone. They look for ratios of testosterone to epitestosterone to help them determine if testosterone levels have been artificially raised. They can also look at subtle differences between exogenous versus endogenous testerone. But, yes, testosterone is on WADA's banned list http://www.wada-ama.org/Documents/Wo...st-2013-EN.pdf. They would not be too concerned about whether a competitors testosterone is in a normal range, but whether it was artificially raised.
