Povetkin failed Drug Test - Fight Off

[powerpuncher]

Supposedly he tested clean for it two weeks before he tested positive for it so it wasn't in his system from months ago

That is good to know and have seen similar reports but its still not definitive. They said they had not used since Sept 2015. They tested negative 3 times in early April but got a positive late April. Again I am not a bio chemist but is it possible that this agent could show up randomly after use is stopped?

Doesn't seem likely but anything is possible. He got tested clean more than once before getting a positive test. That makes me think it wasn't a coincidence.
