Black Market in Anabolic Steroids—Analysis of Illegally Distributed Products
Anabolic steroids found in the illegal market often do not contain ingredients declared on the label. Forty-two products encountered in the illegal distribution channels were analyzed by gas chromatography/mass spectrometry. Fifteen of the products did not contain the expected ingredients. Mainly, counterfeits of parabolan and primobolan products were found. Instead of trenbolone or metenolone, the cheaper agents nandrolone or testosterone derivatives were identified. In one product the gestagene progesterone was found. In two other cases no steroid was present or tocopherole was substituted.
