Was yours the same Quest test? The GC/MS? Were you supervised at all? I was getting nervous about using a synthetic and was about to order some frozen from PerfectUrine, but if you passed the same test using QF then I'll save my money. Before I found this board I spent way too much money on some Duz'z It drink that now seems worthless. Then I ordered the QF 'cause I didn't want to mess with refrigerating real stuff but knowing what I know now that seems to be the best way to go. But I'll go with the QF if it worked for you on the same test. I'm not anxious to spend more money on this. I wish I had a clean friend that I could trust to give me some of their pee!
