What brand of adulteration test kit did youve used and where did you order them from(without posting any store links)?

About 5 years ago, Ive ordered a few strips from the craigmedical site. These strips had the panel for oxidant/PCC and had tested a QF 4.0 bottle which showed a dark pale blue (abnormal). Ive tested another 4.0 bottle from an acquaintence which was the same thing. Suspecting that something was fishy, I tested my own urine with another strip and, youve guessed it - dark pale blue for oxi/PCC. Theres no way in hell my body (or anyone else for that matter) can naturally produce oxi/PCC. With 2 strips left, Ive tested the urine of that same acquaintence and got the same dark pale blue result. I was now convinced that these craigmedical strips were garbage, so I trashed the last strip and ordered some Urinecheck 7 adulteration strips (which do not test for PCC), and had no problems at all - then or since.
