DETECTION OF STANOZOLOL METABOLITES IN BOVINE URINE AFTER INTRAMUSCULAR INJECTION

Stanozolol is an anabolic steroid which is often found in injection si tes sampled from cattle at the slaughterhouse but has never been detec ted in tissues and excreta of animals during regulatory control. Most probably the difference in structure of stanazolol and the other stero ids is the cause of this phenomenon. In sports doping (man and horsera cing) stanozolol was subject for abuse too and became the subject of s everal research groups. In this investigation veal carves were treated with intramuscular doses of stanozolol. In the urine of these carves the stanozolol metabolites 3'-hydroxystanozolol, and 16 beta-hydroxyst anozolol were detected. These are two of the known urinary metabolites of stanozolol in man, which were obtained from the doping laboratory of the ''Deutsche Sporthochschule Koln'', Cologne, Germany.
