Looks like they "all" dope. Their doctors know how to cover it up, with various substances, like taking Epitestostosterone. Someone screwed up his Epi dose, he took too much, thus the 11:1 positive test. Thats one theory anyways. Its not that he took a boost shot that morning, its that his masking agent didnt work.
Now what do you have to back that up? And what making agents do they use?
How would you mask synthetic testosterone? Looks to me like this is the definitive test to put a stop to this nonsense.
The real loser here is the sport of cycling. It puts the clean riders in a category of never being able to win. And it puts the ones who win always in the category of suspected dopers.
How can anyone believe that the winner actually "won" or just cheated his way to victory?
As I have said before here and elsewhere, the first offense is the last offense. If they are caught they are banned for a lifetime.
We now know that Bonds doped. McGuire doped. Sosa doped. And any number of other baseball players doped. God only knows how many NFL players doped.
Ban for a lifetime and any doctor or trainer who is involved lock them up for a lifetime. We have to stamp this cheating out or sports will mean nothing in the future.
