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. 
Trenbolone Acetate Tren Acetate behaves like many other anabolic steroids. It enhances your body’s ability to synthesize protein and it helps your muscle tissue retain more nitrogen. When your body is able to create proteins more quickly, and when the building blocks for those proteins (namely nitrogen) are available in abundance, you can experience muscle growth on an epic scale. Aside from this, Trenbolone Acetate will also work to promote insulin-like growth factor, which is responsible for repairing and rejuvenating tissues throughout your body. It also increases red blood count significantly; with more red blood cells, you can better oxygenate your muscles and provide them a prime environment for growth.
If LVH from AAS use is nothing to worry about, is there a downside to my low dose TE OR TPP/NPP year round? I know that there are some individuals that have to be on some type of high-dose AAS 24/7 for many years and even decades, examples being Jose Canseco, Hulk Hogan, and Superstar Billy Graham, with each of these individuals not having any type of heart related ailment that I am currently aware of. On the other hand though, the autopsy report of Eddie Guerrero noted that one of his reasons for death was acute heart failure, so I don’t know if this may have been attributed to AAS induced LVH or not.
