Actually, Armstrong did tested. More than once. Can you say EPO? Can you say retroactive testing? 1999. Check it.
Face it. Armstrong is a dirty lying scumbag. Nothing he does will ever be clean. He can't win clean, and he deserves no amount of the money that he is making off of people's sympathies, especially cancer survivors. What a shame and a low-life he is for misleading these people for his own gain.
