Point is they will and must have some PED program, even the WWE has one, of course its just a front or there are fighters still beating it, but the US or most worldwide pro leagues have some form of it, they cant just go ahead without one, Boxing for instance does not have USADA afaik, but they do have some and bigger names usually have WADA/VADA (or whatever it is) anti PED programs, the UFC will end up with one of those, its because they have to, also probably cause the AC's enforce it, the same will happen with the UFC, they cant go back to the Pride days of no testing, or fake testing, even if they dont care, of course the promoter doesnt care, specially at this point where the UFC is the stablished MMA brand, the promoter does not care for medicals, the AC does, PED's are in the same boat.
