It means that on the day of the feat, he would be able to show that his liver is not about to fail, his prostate is probably functioning and his testicles might actually be working. A very different proposition to the lifter who shows up in an untested forum with yellow eyeballs, LFT's in the thousands, no nuts and bleeding from every orifice. The loaded up guy with the elevated liver function has a very significant advantage compared with the dude who shows clean levels on the day of the lifting, no matter what anyone believes about the efficacy of OCT.
