Could someone please let me know if test clear powdered urine has a shelf life ? (I mean unmixed, off the shelf of course)

Thanks very much
loudlove Reviewed by loudlove on . Questions about Quickfix... shelf life and practice? Hi everyone :) First off I just want to say thanks for having such a great site full of resourceful information... definitely a big help and adds some peace of mind. My employer does random drug testing and one of my friends who works for the same company got hit with a random test this week. I had not seen anyone get tested in the 3 years I've been with the company so it was sort of a shock even though I knew they did it. It got me thinking and I figured I need to be better prepared Rating: 5
