I'm 6'4" 200 lbs, I'm a big meat eater and have an average metabolism. I've been a heavy smoker for years, but I cut it off for a week, then smoked twice, cut off it another 8 days, and my test is tomorrow. I have two options: 1. Detoxify XXTRA CLEAN which I bought from my headshop. 2. Dilution according to this forum. I took a home test 2 days ago after following the dilution thread and PASSED. (I actually didn't have the Creatine, but I used the aspirin and Super B Complex vitamins - my pee was noenish yellow). I took a home test today with the first pee of the morning and FAILED. The test that I have to pass for my job is a QUEST DIAGNOSTICS SAP 10-100/300 W/NIT. I understand this is a 10-panel screen, but I don't understand the 100/300 part. From research I believe the w/NIT part means they check for Nitrates. Here are my questions: I bought some Super B Complex vitamins from CVS and one of the ingredients is "Thiamin (Vitamin B-1 as Thiamin Mononitrate)." Is this going to trigger any alarms since they are testing for nitrates? Does that also mean they check for adulterants - like anything that might be in Detoxify XXTRA CLEAN? Should I be worried that this drink may test positive for adulterants or is that just in "Klean?" I don't see anything on here with the word "Nitrate" in it but I'm no chemist so I don't know what breaks down into nitrates or anything else that might trigger an alarm for adulterants. And I want to pass the test, I don't want a dilution. I'm torn. On one hand I've passed the home test already with the dilution thread, but will that mean I just have to test again? On the other hand, my friend used Detoxify XXTRA CLEAN and it worked perfectly for him, and I might just go with it - but I don't know the specifics of the w/NIT part of the test and if they will notice that I used a cleaning drink. What about both? Help would be appreciated, and please cite your sources of some kind so I know if you know what you're talking about - this is a serious job - no 711.
