First off, make sure they’re not on a banned list… if you’re in DoD, for instance, DMAA has long been ‘banned’, and sometimes they have provisions that say “no similar compounds” like WADA does (DMHA isn’t specifically banned by WADA as far as I know, but it’s close to DMAA and therefore banned).
On to the test, I think it depends on the test itself. DMAA was causing false positives way back in the day. A more rigorous test would then determine that it was not an amphetamine. I believe most tests have this figured out by now, but the cheaper ones you can buy yourself may still not be up to snuff.
Best idea is to pay for a test yourself. This one cost me $50 at AnyLabTestNow and Lipodrene Elite had me clean:
But that’s a better test they administer than the home use kits.
So basically, @Brawn is right – it’s typically nothing more than a narcotic/pot test.
For the record, PricePlow does not drug test its employees, except when doing supplement reviews Although we may need to spring one on Robert
