...either use a substitute urine sample or get Quick Fix. The pre-employment test will not monitor you unless you do something ahead of time to make them.

I ordered Quick Fix and will be using their bottle for temp. notification but will be using clean urine instead of the synthetic. Everthing I have read in here and elsewhere on the net shows that Quick Fix works, check out this link and watch the video: Fake Pee Will Beat Any Drug Test!

I have practiced at least 10 times and have learned that any liquid when placed in your crotchal region maintains a temperature between 95-97 degrees. The longest I timed it was an hour and it was something like 95.9' (acceptable range is 90'-100' at most facilities).

I ordered Quick Fix from the linked website on a Saturday night and it arrived on a Tuesday. I also picked some up for considerably cheaper at a head shop.

If you wanna be sure to pass - this is your ticket. There are plenty of threads on this forum -- explore, learn, and practice. Happy smoking!
