Don't you have to heat it up? Unless you get the temperature in the level, it becomes questionable. Especially since some of these testing companies make you wait a long time to prevent successful substitution. They do it on purpose to throw off the temperature of your synthetic urine.

Substitution isn't a bad concept if it's done right, but you gotta have a back-up plan if substitution fails because you got caught up. You can use your real urine that could be clean if it came down to it. Plan A, and Plan B.
thcbongman Reviewed by thcbongman on . QF 4.0...FAILS! Had a pre employment DT yesterday. I've never used this stuff before but my brother recommended it and claimed it worked for him both times (must have been a diff lab). Anyways took it in and turned in the sample of Quick Fix at a recorded 96 degrees. Took the guy about 15 seconds after taking it from me to tell me it was fake piss. Lab is ADC (or American Diagnostics) in Portland, OR. Just a word of warning for anyone in the area! Well I was feeling pretty bummed all yesterday but Rating: 5
