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. 
A 53-year-old woman used a patented Chinese medicine in tablet form called ‘Lidan’ (also contains Gold Coin Grass as the main ingredient) for 3 years. It did relieve her shoulder pain and reduce her gallbladder pain from constant pain to a few attacks a day. When she started using Gold Coin Grass (GCG) in tincture form, her pain was reduced to only one attack every few days within two weeks of using the tincture. After finishing one 250 ml bottle of the tincture, she did liver and gallbladder flushing, and her pain disappeared completely.
