I can't remember where I heard the argument, but basically they were talking about PED's being an example of athletes using technology to gain an advantage. A number of these new designer steroids are specifically designed scientific suppliments to improve the preformance but what about some of the other over the counter suppliments that are deemed ok? How do you draw the line? What about guys who get ligament replacement? Isn't that enhancing their performance? There have been high school kids who have ASKED to get Tommy John surgery because they beleived it would make them throw harder (FSU had two pitchers in the late 90's that increased there velocity post surgery). What about Lasik surgery?
