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. 
Although Anavar has been wrongfully touted as being a ‘mild steroid’ in the area of anabolic capability, studies have shown otherwise, and as previously mentioned thus far, it is a compound that is 3 – 6 times the anabolic strength of Testosterone. Therefore, in the athletics and bodybuilding world, Anavar dosages for beginners tend to start and stay in the 25 – 50mg per day range and should provide great results whether bulking up or trimming down the fat. Advanced users tend to venture between 50 – 80mg per day, and there is usually no need to exceed this range due to the dramatic results that such an Anavar dosage can provide. Very rarely, however, experienced advanced Anavar dosages venture within the 80 – 100mg per day range.
