How am I supposed to know. I'm not a chemist that knows which time a drug works. All I know is that he was jacked up against pac and hurt him like he never has in any fights. a 40 year old career featherweight punching like that and moving up 2 divisions and suddenly able to not only knock down pac but ko him. He never showed that power in his prime division now he can at welterweight.
And the Bradley fight wasnt there testing and regarding vargas u obviously need talent also.
