No it seemed to me that Pianeta had been positive but my memory may play tricks on me. I thought Wilder was the only one to never have been positive.
It's an insinuation that Wilder cycled off and lost mass. Personally I'm of the opinion that everyone is on something, I mean even OTC things at GNC are by and large likely banned substances. I don't think there's alot of items you can take as supplements that aren't. And let's be honest, these athletes (for the most part) aren't scholars, they have no clue what their teams are pumping in them. They probably still think PEDs are things injected (most of the general public still believes this), so why wouldn't they. That being said, people need to do a better job of knowing what goes in their bodies.
Exactly how much mass did he lose? I think against Fury he lost a couple of pounds between the weigh in and actually getting in the ring but that is normal considering he would not have had to cut weight for the weigh-in as there is no limit for heavyweight. What is OTC and GNC?
Sorry bro: OTC simply means purchasing items "over the counter" as in no prescription needed. GNC is a nutritional supplement store "General Nutrition Center", they sell pretty much all kinds of nutritional supplements. It couldn't be much mass that Wilder lost, I think he's lost only 6 pounds between his last 3 fights.
