I'm leaning toward using the quick fix method; the drinks and even diluting doesn't seem reliable, and I smoked one day recently and heavily a few weeks before that. Does anyone know if labcorp will recognize quick fix 5.7 as synthetic? I'm fairly certain I have a good batch, even called to confirm, and I keep hearing that if you get the temp right you're all good. Pre-emp test and I doubt they'll watch, and I have a way to keep the stash hidden in the undies even if they do. My only concern is the test result will come back non-human urine. I've seen hundreds of posts saying QF works and only 1-2 claiming the lab saw it as synthetic, also heard only Oregon is really testing for that. How sure is Quick Fix?
