You're missing the point with all due respect. He is under NO contractual obligation to do it. Therefore, he does NOT have to do it. He should voluntarily do it, especially given his previous, outspoken stance on PEDs and the fact that his opponent is doing it.
By refusing to take PED tests for whatever reason, e.g. contract or not, it is suspicious. I wouldn't go as far as to say he is taking PEDs because innocent until proven guilty, but again it is suspicious.
