MAXINE: Testosterone - Where There’s Money, There’s Doping

Floyd Landis gave an interview and defended himself along with his Doctor stating that Testosterone is not a friend ... but an enemy to the bicycle racer's performance.

Further, Landis, through the statements of his lawyer, Luis Sanz, said he fully expected the backup test to come back with the same result, because the testosterone imbalance was produced naturally by his [Landis'] body.

What is at question here is the difference in levels between testosterone and epitestosterone that appear in the body. The blood testing showed an abnormal balance/ratio in the levels of testosterone/epitestosterone.
