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 Phase III , randomised, 12 month clinical trial (CS21) in prostate cancer  compared androgen deprivation with one of two doses of degarelix or the GnRH agonist, leuprolide . Both degarelix doses were at least as effective as leuprolide at suppressing testosterone to castration levels (≤ ng/mL) from Day 28 to study end (Day 364). Testosterone levels were suppressed significantly faster with degarelix than with leuprolide, with degarelix uniformly achieving castration levels by Day 3 of treatment which was not seen in the leuprolide group. There were no testosterone surges with degarelix compared with surges in 81% of those who received leuprolide. Degarelix resulted in a faster reduction in PSA levels compared with leuprolide indicating faster control of the prostate cancer. Recent results also suggest that degarelix therapy may result in longer control of prostate cancer compared with leuprolide. 
Cardiovascular disease: This medication often affects blood pressure and can contribute to symptoms of heart disease. If you have high blood pressure, heart disease such as heart failure, angina, or a previous heart attack, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. If you are taking blood pressure pills to control blood pressure, it is important to continue taking them regularly while you are on epoetin alfa. Your doctor will monitor your hemoglobin (the protein in red blood cells that carry oxygen) until an appropriate dose of epoetin alfa has been determined.
