FWIW - while I don't know exactly what they are/aren't testing for. I know the B1G does drug testing randomly at B1G competitions; by which I mean random competitions not randomly at all competitions. Of the B1G championships I was involved in from an event/facility management side of things, two had drug testing. One was a team sport and 3 athletes from each competing team were randomly picked for the piss test. The other was an individual sport (think wrestling, swimming, track, etc) and in that one the winner of each weight/discipline and one other random entrant were drug tested for all weights/disciplines. There were more B1G championships that I oversaw that had no drug testing but every B1G championship I was involved in had a line in the packet that said all competitors may be subject to drug testing.
