BACKGROUND Effective control of the use of anabolic-androgenic steroids (AASs) in animal sports is essential in order to ensure both animal welfare and integrity. In order to better police their use in Australian and New Zealand greyhound racing, thorough metabolic studies have been carried out on a range of registered human and veterinary AASs available in the region. RESULTS Canine metaboli...

Recently, a sizeable number of urine samples analysed by official laboratories tested positive (>2ngIml) for the nandrolone metabolites 1 9nortestosterone (19-NT), 1 9-norandrosterone (19-NA) and 19noretiocholanolone (19-NE) (1-6). The large number of positive tests in such a short period of time, combined with the fact that some sports involved had not previously been associated with the abuse...

one at the concentration of 7 pg/mg. This result was not challenged by the athlete. Nandrolone has also been identified by this laboratory in the hair of bodybuilders, in concentrations of 1–7 pg/mg (8 ). NA and noretiocholanolone were not detected in any hair. The sensitive, specific, and reproducible method developed appears to be suitable for the detection and quantification of 19-norsteroid...
