He had hundreds (at minimum) of tests in his entire career and never failed one? Yeh what a cheat. The last time I chekced hearsay was not enough to convict anyone.
There are so many things that aren't or weren't detectable by normal doping tests to make this statement meaningless. (the bio-passport is better, but only provides indirect evidence, which you would call "hearsay" if it relates to an athlete you like).
Also: 500 tests? Bullshit.
And keep this in mind:
“I was tested 200 times during my career, and 100 times I had drugs in my body,” he said, according to the New York Times. “I was caught, but 99 other times, I wasn’t. Riders think they can get away with doping because most of the time they do. Even if there is a new test for blood doping, I’m not even sure it will scare riders into stopping. The problem is just that bad.”
