So a fighter should just buy 1 of every supplement out there on the market, pay out of their own pocket to have all of them tested, and hope he comes across one that doesnt have an ingredient on the label where that ingredient is banned(oh, and it has to be the ingredient for which he would be getting busted for, and not some random other one)? Seems like a whole lot of work and money. Not to mention the fact that if it was uncovered that you were independently testing substances, and still got busted like this, that defense goes out the window too.
