Lol it's not the PED's that give him his cardio.
Cardio is probably more than 50% mental. Who here has done something like run 10k with ease one day, and almost die doing it another day? You can train your mind to control your bodies use of oxygen.
As some of you smarter people above me have said, he has been competing his whole life. He doesn't get nerves, stress, etc like others may which would cause those disastrous adrenaline dumps and mismanagement of his oxygen intake.
