Remember when Vitor and Hendo were on that shit? And they were doing things they otherwise wouldn't have been doing? And we were all hyped AF over it?
I think fighters should play within the rules of where they're fighting. Fight in Japan or Russia? Use PEDs all you want, they're not against the rules. Fighting in the West, under unified rules? Don't cheat, don't use. Use your skills. Use technique.
That said, I agree with Andy. When TRT was legal we got some awesome moments that we otherwise wouldn't have ever received. They should bring it back. Fuck it.
