Ok, so I went a little too far with the whole getting kicked off the team. But I did find this on the NCAA website about "Dietary Supplements".
"Many nutritional/dietary supplements contain NCAA banned substances. In addition, the U.S. Food and Drug Administration (FDA) does not strictly regulate the supplement industry; therefore purity and safety of nutritional/dietary supplements cannot be guaranteed. Impure supplements may lead to a positive NCAA drug test. The use of supplements is at the student-athlete's own risk."
As you can see I'm not very fond of people using Creatine.
