Its a giant loophole, and its almost getting to the point now where its time to say **** it and either do some real testing or not even bother..... right now the only ones who get caught are the ones who **** up on the test, and you'd have to be either really uninformed or using a substance like deca unknowningly.
IMHO there is no way Dana White doesn't know either, its the same as McMahon in WWE or Major League Baseball...... Bigger, stronger athletes make for better fights, makes more money...... I wonder what would have happened if Brock has tested positive a year ago? Or why Sonnen wasn't booted?
