Metabolite Identification
Common NameEthyltestosterone
DescriptionEthyltestosterone is a steroid metabolite; it can be the result of the administration of synthetic steroids used in the past in different anabolic therapies, such as in tuberculosis (i.e.: Dianabon in 1946), or in gynecology (1960's). These abandoned or never commercialized anabolic steroids have been taken up by producers of 'designer steroids' and re-introduced as aids in sports, sometimes with modifications to their structure to avoid being detected in regular screening for doping. These anabolic steroids constitute a threat to the spirit of integrity and fairness in sport and to the health of athletes, since their side effects are unknown. The use of anabolic steroids was banned by the International Olympic Committee for the first time at the Olympic Games in Montreal in 1976. Ethyltestosterone is a common standard used in the screening for human steroids in human urine in sport doping control. (PMID: 15934041 , 15712346 ).
