I agree with the biochemist! I have used mas spec lots and know that it is extremely sensitive and the results are what they are. Go ahead with the "contamination" arguments .

Has Floyd never been tested in another race before? If he had high testosterone levels naturally (even if it's just during a race, dehydration, etc.) then the elevated levels would be there during another race. He's a nice guy, he wanted to win, he thought he could possibly flush it out with all that water he was drinking the next day and no one would be the wiser. Got caught. Basically it doesn't matter what any of us think because it is up to the UCI and/or the courts.
