Bellator doesn't test with USADA, they test with the state commissions. The commissions are usually less stringent when it comes to testing. Bellator can also just book him on an Indian reservation or book him on an overseas show so they wouldn't need to test him.
They can just put the cage on a boat and drive to international waters
Ryan Reeves (Ryback) did an interview with Sports Illustrated, and gave some clues as how he was able to keep his physique in a drug tested environment. For years, several in WWE would bring up to me how guys weren’t happy because he was allowed to keep his physique, so to speak. I always thought that meant he just had access to stuff that you couldn’t catch,
but in actuality he was given a testosterone use exemption because he had burned out his own system by taking steroids. He said that he had low testosterone, saying he used steroids when he was younger, his natural production was shut down and it never came back. He said he was given an allowance for TRT. WWE had banned usage of TRT for its talent in 2007 except for those who they had already given approval to before that time. In theory, that makes sense, because if you allow people usage of TRT, the theory is the body becomes dependent on it and won’t function well without it. The theory isn’t the case because, as we’ve seen with MMA fighters given that approval, that when it was banned, somehow they functioned just fine, although many couldn’t fight as well and went from being Vitor Belfort 2013 to Vitor Belfort 2015. And Ryback was Vitor 2013.
One of the great misconceptions of testosterone replacement therapy is that it is not an enhancer in sports but simply gets someone whose body is damaged “back to normal.” In theory that’s the case and it’s been sold as being the case. But studies of athletes have shown that those with high testosterone, average or even a little low, does not really affect performance. In testing of MMA fighters, who are some of the hardest training athletes around, most of the fighters at the top tier had average or even lower than average testosterone levels, yet they had quality physiques and could perform at a world class level in a very intense sport. That’s the case with those who haven’t used steroids as well as those who have. If you’re serum testosterone natural level is 350, which is kind of low, that doesn’t mean you won’t do as well in sports or function as well as a guy who is at 800. However, if you boost yours to 800, still in the normal range, you are going to be enhanced as hell while your opponent, also at 800, will be normal and greatly disadvantaged head-to-head. That was the con of TRT in MMA and in wrestling and why the guys on it were able (and in some cases, you combined that with undetectable GH) to develop far more impressive physiques than everyone clean could, even though their reads were “normal.
