I don't know if y'all remember but there was a Dr. from Canada that had HGH in his vehicle crossing our northern border, he was caught & one of his clients was Tiger Woods, it was all swept under the rug. I would say both Tiger & his woman Lindsey Vonn on both on, but I think PED's should be legal, never going to happen though! I've been told Masteron is very common in crossfit, bjj, & mma.
