I just wanted to post for anyone out there facing a pre-employment test and is worried about using Quick Fix 6.2 that I’ve passed two consecutive tests with it. I know how nervous you may be! The hardest part is getting the confidence to actually go into a test and use it. I went to two different labs with it stashed in my chonies. Follow the directions that come with it when you buy it. You want to practice how you are going to get the bottle in your underwear and how you are going to actually get it from bottle to a test cup. Sounds silly but you don’t want to be figuring that out at the actual test. While the lab tech is not in bathroom, they will be listening on the other side of the door for anything unusual or if you are taking a lot of time. I’ve gone completely straight because I have to take randoms now but this is for anyone facing the same fears I had go through my head when I took mine.
