ok now I'm reading the canadian version has beads of uric acid to add, meant to fool labs around oregon. I'm nowhere near oregon but still freakin.

As i said my diluted void came up faintly negative twice, so I guess I could add some to the QF for smell and uric acid, but I'd be scared to add much in case I dirty the synthetic...

BurntToast and Killer420, you seem confident. Is my own diluted or QF 5.7 (not from canada) the way to go?
