True enough statement but, it raises eyebrows when a fighter has any amount of a banned substance in his system! One can argue that the amount found was inconsequential but, that only applies if that was the amount taken! He could have taken the substance in much larger amounts and what was found, was the leftovers from the depleted source drug! which would mean, Pov had already reaped the benefits of the drug!
Povetkin wasn't eager at all to get VADA testing for a reason. They had something to hide and got caught. There's a small but loud contingent of folks trying to make believe he isn't at fault.
