Jones has two confirmed PED failures.
UFC 200- Clomiphene and letrozole
UFC 214- Turinabol
It's technically 3 though.
At UFC 232 he continued to fail for Turinabol and they made up the pulsing excuse. The issue with it is the study they used to base his pulsing off was done on clomiphene.
Jones also has a previous failure for clomiphene, but magically only pulses for turinabol.
So he fails for clomiphene and 12 months later he isn't pulsing magically when he fails his next test for turinabol, but 18 months later he can't be guaranteed to pass a drug test after "accidently" ingesting so many steroids, he can never be guaranteed to pass a test again? To add to it multiple members of his team pop for the same drug and his NFL playing brother.
I never said Fedor hasn't used PEDs, he probably did during Pride because it was legal. He has never failed a drug test in a tested MMA org unlike Jones, who has 2 recorded and would have been banned from the sport if they had treated his 3rd failure correctly.
