I don't. They could be lying.
As for all the examples, like Galizynov, Hounard, etc... I think the biopass, for legal reasons, is more effective at targeting athletes, than actually bringing violation charges against them. targeted athletes tend to panic and stop doping, or get caught. Thats where it is efficacious, not in its actual ability to throw positives.
It's more effective as a deterrent and a limiter. But, this is where we differ, for me, that's still great news. Ive said this before: I don't care if people are doping, I care if it's possible that my team wins clean. If that remains in the realm of possibility, I am happy.
(of course I would be happier if no doping existed at all)
Why am I so non-idealistic here?
Because I lived/raced through a time period that makes this era look like an absolute utopia. Races were not won clean, ever, in WT racing when I started in the pros. So, you have to realize the stark contrast I see. Maybe it makes me more optimistic than you would like. But those are my life experiences.
