Well, technically you should just drop out of the meet. If they do happen to test you then you are going to get suspended (probably 2 years or something like that) so if you want to compete in USAPL in the future you should just obey the rules. USAPL was threatened with being kicked out of the IPF a few months back due to something with failed drug tests (I don’t know the whole story) so it’s possible that they are getting more serious about their drug testing. Here in Canada the IPF affiliate never used to test anyone except the top couple of lifters at nationals but now there is a drug test fee as part of the cost of registering for a meet and they are testing more people.
Remember, winners don’t use drugs.
For real though, I strongly advise staying the hell away from preworkouts, those are the supplements that are most likely to have banned shit in them. The one that made Jesse Norris test positive, Craze, was taken off the market around that time. A bunch of “natural bodybuilders” at the gym I used to go to were hooked on that stuff, a couple of the told me that nothing else really did it for them, Craze just got them extra hyped up. Turns out it had something similar to crystal meth in it. I tried a bunch of different crap, which was mostly just overpriced caffeine. Superpump Max must have had something else in it though, everyone I knew who took that stuff had significant strength gains from it. After about a month it seems like it stops working, like you develop a tolerance to whatever is actually in it. At the time I thought it was a combination of the stuff that they actually list, but when you look into it there is nothing that would have a significant effect. For an energy boost, anything beyond coffee, energy drinks, or caffeine pills is nonsense unless you want to take actual banned substances.
