In American pro sportsI would say PEDs aren't very common anymore. Too much testing and too much punishment if you get caught. Just look at homerun numbers from the 90's and now. These days players hit a fraction of the homers guys in the 90's did. In the NBA, 90% is height and basketball skill, 10% strength. You also got to remember that the top athletes are the .1% of genetics, and those guys actually can get big and look like that off genetics alone. Look to fringe sports like wrestling for PEDs.
