Just wanted to share my success story since reading stories here for the last week really helped my anxiety. Throwaway for obvious reasons.
I am a medical patient using marijuana daily with a card legally in my state and was offered a great job but had to pass a 10 panel urinalysis at Labcorp. Initially I bought a 3oz pack of QuickFix at my local head shop but after reading here about bad batches I went ahead and ordered directly from QuickFix as well. I did end up taking both bottles as a precaution as I read one is sometimes not enough to test but only ended up using one.
I went into the test the morning of 4/20 with two bottles in my bra and after waiting about 30 minutes I was able to successfully empty my bottle for testing. Passed the temp check and was tagged and bagged and out the door in ten minutes.
I spent a week tripping out, reading posts here and convincing myself I was good. Got the word yesterday I passed and start my new job soon!
My QF was checked on their site, batch was from 11/25 and worked great. I followed the directions on the bag, stored in my bra for the trip there with hand warmers, and had no issues with temp during testing. This stuff is seriously amazing.
