I understand where you guys are coming from, I just don't agree that they should overturn anything on account of Petersons admission alone. As I said, it's quite possible that he didn't have an abnormal test for the first fight because his levels of testosterone weren't abnormal. I would imagine that synthetic testosterone in itself can't be detected or differentiated from the natural hormone, the only give away would be having a very high level in the blood. Furthermore, who is to say with certainty that Khan didn't use something banned himself? If the fighters both passed whatever tests they had to take then it should be done with imo, this incident merely highlights how inadequate the standard tests are in the first place. Shane Mosley didn't have his win over De La hoya overturned even though he has admitted to using designer anabolic steroids along with EPO, much more serious than synthetic testosterone.
