I think your timescale is off there fella, i think the supplement or one of the ingredients in the supplement had been banned for a while, in fact athletes had been banned prior to Whyte for taking it.
Like I said you can't give those excuses anymore, I believe with VADA and possibly UKAD you can speak with someone over the phone and ask about any supplements you are looking to use and they will confirm wether it's safe or not.
Regarding PED's, I'm of the belief either clamp down on it hard or have a free for all. If fighters are willing to fcuk themselves up to win
