As far as the Specific Gravity tests, an unexpired, untampered synthetic batch that had been stored properly will register a satisfactory S/G. You can run your own S/G test on the synthetic with a validity test strip. These inexpensive kits are found by doing a Google search for "drug adulteration test kits".
Thank you for the reply. I just got off the phone with a quick fix rep who said my batch #, which is P4GGG-13C) is new and no issues as of yet. She said wv, oregon, california, another state i forgot, washington and hawaii test for uric acid only. Minnesota does not. So that is good.

She did say that SOME labs can flag it for not foaming and test further, but did not mention that they can tell if it's not real pee. I'm 50/50 on whether I should use quick fix or my relative's pee, since she has been clean for over 30 years.
