Hi there everyone! I am posting my experience on here for not only other users, but also for reassurance. I just used Magnum Synthetic Urine for a UA at LabCorp in Texas. I know the test is a 10 panel test and I am hearing mixed results on what has happened for people in this situation. The test is done and over with and im just waiting on the results, but I would really like to hear any stories anyone has about their experience with Magnum Synthetic Urine or LabCorp. I am stressing big time, even though i have used Magnum in the past and it worked, I will stress till the results come through. I actually stopped smoking and it has been 44 days, but I can still not pass a home test so I had to result to using Magnum. I followed the directions exactly and the bottle actually read that the temp was 98, but when i placed it in the cup it seemed like the temp dropped. I saw the 90 degrees line light up but she took it from me before i could see if it went up.
