They also complain that as substances are added to the banned list, athletes who have taken a previously legitimate food supplement are left open to a dope charge. That’s especially true of the anabolic steroid nandrolone. Until 31 January this year, when the International Olympic Committee (IOC) extended its banned list to close a perceived loophole, athletes were allowed to consume food supplements that contained norandrostenedione or norandrostenediol. These substances can be converted by the body into 19-norandrosterone, the main metabolite measured in the nandrolone test. And while the anti-doping scientists say that innocently taken food supplements won’t cause a positive result (see “Dope tests on trial”), athletes are not reassured—particularly because estimates of how long the substance remains in the body range from two weeks to one year. Patrick Schamasch, medical director of the IOC, agrees that more athletes are testing positive for nandrolone. But he explains it differently. Schamasch argues that since accredited labs started to use improved high-resolution mass spectrometry equipment in 1995,
