Heavy consumption of the essential amino acid lysine (as indicated in the treatment of cold sores) has allegedly shown false positives in some and was cited by American shotputter C. J. Hunter as the reason for his positive test, though in 2004 he admitted to a federal grand jury that he had injected nandrolone.  A possible cause of incorrect urine test results is the presence of metabolites from other AAS, though modern urinalysis can usually determine the exact AAS used by analyzing the ratio of the two remaining nandrolone metabolites. As a result of the numerous overturned verdicts, the testing procedure was reviewed by UK Sport . On October 5, 2007, three-time Olympic gold medalist for track and field Marion Jones admitted to use of the drug, and was sentenced to six months in jail for lying to a federal grand jury in 2000. 
In 2005, Superdrol was rereleased as an over the counter designer steroid. It was sold in many supplement stores without restriction. This was pulled off thanks to a “grey area” in the 1990 Anabolic Steroid Control Act and 2004 revision. The law is, in part, drug-specific and Superdrol was not declared a Schedule III class anabolic steroid in that act because it was not commercially available at the time the act, and its subsequent revision, were signed into law. Superdrol was therefore being sold as an over-the-counter dietary supplement.
