for one: look at the section under "passing testing" on this website and others. It will explain alternative ways to pass tests and find ways around the cycles that make testing easy to pass. Also, most NCAA testing is not as often as you would think. Maybe zero to 4 times a year maximum, it is expensive to test so many athletes. There are hundreds of athletes, expecially for colleges the size of UT Austin, which is the largest University in the nation along with being one of the top in academics and athletics. It would be too expensive to constantly test so many athletes on a 6 or 8 week basis.
