You can't always look at people and tell if they are doping or not. Some of the UFC guys that were caught doping in the past didn't look like they were doping. Since this victory came up and I knew about the Russian state sponsored doping program, it actually made me look more into it. There is a Netflix documentary on it too called Icarus. The Russian that was the director of the Russian anti-doping lab had to flee Russia and get into the FBI's witness protection program given that the Russian state would try to come after him stateside.
The Russian anti-doping lab was regarded as one of the best in the world, but the rest of the world didn't know it was also used to successfully hide the doping of Russian Olympic athletes and to assist in doping in those athletes. The Russian guy was a huge fan of Orwell's book on 1984 and he said his position at the anti-doping lab reminded him of "doublethink" that Orwell talked about where the public title of his position and lab was anti-doping but his job was really to dope athletes and find ways for it to go undetected.
He said there has never been such thing as a Russian anti-doping lab when it comes to Russian atheletes and it has been existence I believe he said since the 1960s. It was a good documentary and the Russian guy who was the former head of the Russian anti-doping lab is a good guy who was funny as hell and had a great sense of humor. Good fellow.
Here is a link to the Russian director I am referring to: https://en.wikipedia.org/wiki/Grigory_Rodchenkov . His name is Grigory Rodchenkov.
