My guess would be Jones was just way more reckless with his use. Seems to fit his personality.Same for his competitors, during that period.
Meanwhile, in UFC, in the same period, if Cormier & Glover & co used PEDs, why weren't they USADAd?
Is USADA corrupt?
Has USADA a problem with Jones and leaves the others alone?
Are the others that smart/afford better doctors to get away with it?
Seriously...
