Hey all, I passed my dot dt at concentra this week and I owe a special shout out and huge Thanks to my man at 420green-you are awesome man!! That special hint you gave out about rubbing your thumb on your pants and place it on the urine sample cup to heat up the synthetic urine-worked perfect!! I was able to get my sample right at 96 degrees and never would of thought to do that if it wasn't for your tip and Im forever thankful and I'm here to tell all readers that Quick Fix works and is the only way to test my friends!!
