PTI drug test

i know this may be the wrong section of the message board, but my bros in this area have never steered me wrong. i wound up in pti (those damn bar just arent worth it) and have to take a piss test every month for a year now....i dont know if they test for AS or clen, or anything like that regarding workout gear...i definitlely have been stuffed heavily with THC, i was wondering what the best recommendation would be to pass a drug test....

the detox drink works (or has worked in the past for me-but that was for random testing for work)...

does anyone know if im de****g with a whole different beast in terms of testing for correctional purposes....my main concern is THC

Thanks for the help guys

P.S.
Im kinda desperate, I have a test in about two weeks
