You got all these cheaters getting off easy with the tainted supplement excuse then you've got Machida. He was on an a supplement that wasn't on the ban list of USADA's brasillian page, listed it to them, they pulled him from his fight and now he's suspended for 18 months (putting an end to his career at that age.) Apparently he didn't even test positive for DHEA and 7-keto does nearly nothing. We also have Lombard who tested positive before USADA, looks exactly the same and hasn't been caught by USADA. Boxing is full of steroids as well, USADA doesn't seem to be helping.
