I really appreciate all of this information, but I'm not taking this for the DOT (Department of Transportation), I'm taking this for DOC (Department of Corrections).

Just to let you know, Probation testing (Mine) is not as in depth as other testing. I have never been watched and the bottle never has a temperature strip. I also don't think they ever test for specific gravity because I've given them diluted urine at least 3 or 4 times and have never been told it was too diluted.

The real question at hand (since I've never been observed) is whether or not QF 4.2 can or ever has been detected as synthetic.
