I want Floyd Landis to remain a great champion and his final week in the Tour de France to remain legendary. I also think that there is some reasons to believe that he did not dope. 

I agree with Dr. Gary Walder that testosterone “doesn’t really compute.” First, it is a drug that “would have no effect on performance”. Though Austin Murphy quotes a Dr. Moosburger that it could help. Second, if he was a user, earlier tests during the Tour and other races would have shown the usage. Third, because Landis had previous won a stage, he knew that he would be tested at the end of the stage in question. Fourth, because of the risk of even accidental contamination, I would think that there would not be any testosterone within a mile of the team or Landis. Fifth, this is a very complicated test says the Donald Catlin who runs the Olympic drug testing lab at UCLA, so it is no slam dunk. Sixth, unlike the media reports of high testosterone, the level was actually normal and the epitestosterone was low. So I would think that scientific studies on the interaction of alcohol and drugs with epitestosteron and the ratio would be examined (see Washington Post comment by jjouet). Seventh, given his thyroid disease and the approved cortisone shots for his failing hip, there is a slime possibility of someendocrine weirdness. Eighth given the fact that several riders were kicked out at the beginning of the race, doping had to be on everyone’s mind. So why risk it?
