Some people on this board need to get their head out of the sand and do research about PED's and the testing for them. The ONLY, 100% effective test to determine if an athlete is completely clear of all PED's is a MUSCLE BIOPSY. Good luck getting ANY sports body or athlete agreeing to that. At this point...the drugs are WAY ahead of the testing. Many athletes and their "team" (which often consist of doctors on their payroll) know how to cycle off and on drugs and evade getting caught. The fact that Manny refuses even the random blood testing put forth for this fight, makes him look extremely suspicious. Floyd is no angel...and unless this is all some marketing ploy to sell the fight...he has made Pac, his team, and Arum look foolish.
