Well, lemme think off the top of my head here. I can take ephadrine before playing to open my lungs up for more oxygen flow. I can take beta-blockers to steady my hand for accuracy. I can chemically up my endurance level. I can take steroids to build muscle mass for explosive starts from the box, not to meniton being able to get the strength to carry more paint without more effort. Come to think of it, I can smoke a joint to relax before a game too. This isn't to get into the whole "Blood doping" thing too.
Better living through chemistry, or so I'm told.
