USAPL/IPF? If you compete IPF or are eligible for out of meet testing, they use the WADA test, which is more sensitive than the typical in-meet USAPL test (while USAPL follows the WADA list, there are actually two different drug tests...yes, this is confusing). So if you are tested using the WADA test, I would probably specifically stick to coffee or possibly supps that are NSF Certified for Sport. If you compete USAPL and are not eligible for out of meet testing or compete at the IPF level, then you're probably okay with double-checking the banned list with the ingredients on whatever you're using, though if you want to be extra safe, NSF Certified for Sport is still probably the way to go.
