See the following article (in french only, sorry) published today in La Presse, the most important newspaper in Quebec:
GSP essentially takes a shot at Dana and UFC for their perceived lack of support in his actions to get proper testing vs. doping. "UFC is my employer, I don't want to get on their bad side. There are things I cannot say. But I don't want to take journalists for idiots. I thought they (UFC) would support my actions, but I've been disappointed, very disappointed by how things turned out"
In the article, GSP states that he is currently follows both testing protocols (VADA and athletic commission), although he still hasn't received any follow ups from athletic commission (he has already been tested twice by VADA in the meantime).
He also states that the fight against doping has proven to be tougher than all his previous fights in the octogon.
