IamN2pot was right on with the urine luck link.

I use quick fix all the time, even at Quest. I've used it where they test the sample right in front of you and also where they send it away for testing, after the initial temperature check.

The bottle has a temperature gauge so you can be certain it will pass, and to heat it up it comes with a mini-heat pad to warm it up. In a press for time I have used warm water at a bathroom near the test site, and I have also put it on the dash while driving to the site. When it's right, then slip it in your shorts nice and close and walk in the door and pass their damn test.
