Executive Summary
Testosterone precursor under investigation by the Drug Enforcement Administration for possible regulation under the Anabolic Steroids Control Act. A May 10 letter to DEA from Office of National Drug Control Policy Director Barry McCaffrey cites studies by the Swedish Board of Customs and the Canadian Doping Control Lab that find several "andro" products actually contain pure testosterone. To be regulated as a steroid, a product must be chemically related to testosterone, pharmacologically related to testosterone and promote muscle growth. In a separate May 10 letter to FTC requesting investigation, McCaffrey says if testosterone content in supplements is confirmed, "a number of these products are seriously mislabeled" and "contain controlled substances." McCaffrey notes industry reports that use of andro has jumped "five-fold" in the wake of baseball great Mark McGuire's "disclosure" of his use of the substance
