I think track and field is the sport that is affected by juice the most. by juicing you can change your whole performance and become a different person. but say in football its gonna help but its not gonna change your whole game like it does in track. i dont really consider body-building a real sport. theres not much athletic about it. yea you lift weights and flex. but its all vanity, saying bodybuilding competitors are top noch athletes is like saying britney spears is a top notch athlete. both of these are obsessed with vanity, their tan, their abs, and trying too look good for the camera. mabye if the competitions held a sprint and lift competition it would be. but smiling and flexing for a crowd is like beauty competition. all the tanning and fake tanning products, bleach blonde hair makes me sick.
