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 steroid 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. 
Caught: 6/13/07 , following his 38-second knockout loss against Bernard Ackah at Dynamite!! USA .
Tested positive for: Unspecified anabolic steroids. Morton’s pre-fight urine test came back as positive for a very elevated T/E (testosterone) ratio — , when the average for an athlete is 6.
Punishment: $2,500 fine and an indefinite suspension from the California State Athletic Commission. Morton’s $100,000 purse was also withheld after he refused to take a post-fight drug test. He hasn’t competed since.
DHEA is a naturally occurring steroid hormone produced in the adrenal glands by both men and women. Production of it decreases with age. DHEA is not recommended for people under 40 years of age, unless DHEA levels are known to be low (<130 mg/dl in women and <180 mg/dl in men). Therapeutic doses of 10-50mg of DHEA are used by many mature individuals (age 40+) for increase in perceived physical and psychological well-being (improved quality of sleep, more relaxed, increased energy, better ability to handle stress, improved depressive state)1. For men or women who have either adrenal insufficiency or hypopituitarism, although gluco-and mineralocorticosteroid replacement is needed, 50 mg a day of DHEA is sufficient for replacement2. Studies have shown no dangerous side effects from DHEA supplementation when taken in normal recommended therapeutic doses3. With respect to potential increase of the urinary testosterone/epitestosterone ratio (T/E) through DHEA supplementation, studies support DHEA use of 50mg/day or less having only slightly affected levels for a short period of time (2–5 h) without exceeding the 6:1 current acceptable ratio for NANBF and the IPE. DHEA’s effectiveness as an anabolic or energy-producing agent remains unproven.
