When tested the riders are required to give TWO samples. Landis 'A' sample tested positive for high levels of Testosterone.
Landis now can do 1 of two things :
1. Admit to doping
2. Ask that the 'B' Sample be tested in his presence.
If the 'B' sample comes back normal -- everything is over. If the 'B' sample comes back positive, the rider can then request a full physical examination to prove that the level is "natural", etc etc.
These riders are tested all year long.
I think "baseline" is already established for all.
Are the baselines for testosterone an 'average', or are they based on previous testing from each individual rider?
Any idea of how tight is the chain of custody?
