Report on the banned substance nandrolone, 2000.

Photograph taken for the 'Sydney 2000: Drugs Olympics?' exhibition held in the Antenna Gallery, Science Museum, London from June 2000 to February 2001, which investigated drug use in sport. Drug use to boost athletic performance continues to blight many sports. Substances used are increasingly sophisticated and hard to detect, a problem exacerbated by 'masking agents', other drugs designed to hide the presence of the performance-enhancing substance itself. Nandrolone, an anabolic steroid, has been particularly controversial, as it is made naturally by the body and has been found in supposedly 'clean' food supplements taken by athletes who have tested positive for the banned substance.
