i have my UA this week and i got the same Dr. Greens agent X and im nervous all hell. I hear a lot of good thing about quick fix but none of my local head shops carried it. I have been clean for about14 days now and have been testing myself with home "first check" thc tests. I have been passing them but with a faint red line, so i assume i will pass if the cutoff is at 50ml's but still scared to use my own pee if the lab cutoff's are lower like at 15ml's. I would rather sub but like i said i got this Dr. green stuff and noone seems to know that much about it. Any feed back would be helpful, im still freaking out and just looking for any pointers.
