Why VADA is more trustworthy than USADA
VADA automatically notifies the commission when a fighter tests positive for PEDs, that's the reason why Golden Boy stopped using them and went with USADA who have done some shady things. They didn't notify the commission when Morales tested positive, instead they kept taking samples from him until he tested negative. They tested Quillin and Winky but then two days later abandoned the testing at Golden Boy's request and destroyed the samples when they're supposed to keep them for 6 years.
VADA caught Peterson and Berto who works with Conte (there goes the conspiracy theory).
All in all, VADA is a much more trustworthy organization than USADA.
