Anabolics in college track & field

I know that qualifying for a national collegiate sprint event is quite a feat for most college athletes, given the extremely high standards. What percent of elite college track & field sprinters use performance enhancing substances to meet these standards? What is their drug of choice due to NCAA testing? I would love to hear from the T-mag contributors.

Its pretty common. My experience was in DIII, so you only get tested at nationals. DI is harder to get by since you get tested in the fall and also by “random selection” later on.
