From the article:

But most steroids are given in cycles [6-12 weeks] and in context of working out in a gym with weights. It makes no sense to me why an athlete would take testosterone the day of a race when it doesn't work that way. It doesn't make sense in terms of the pharmacology of the drug, and it really doesn't have the attributes that would be attractive to a cyclist -- particularly one running the risk of violating anti-doping regulations.

Maybe there is hope in this. The drug doesn't fit the crime. If he wanted to crush everyone on the stage, he would have asked Amber to bring that bag of blood in the freezer when she arrived from San Diego, and his Hct would have taken a bump. Testosterone would seem to be a marginal benefit for the potential risk.
