well, according to puck technologies tap water will work just fine. and the temp issue isnt really a prob because theres no temp strip on the cup. i piss in it, close it and put it in this bag they hand me and then they put it in a box and send it away to a lab.
jfoster Reviewed by jfoster on . synthetic urine i know the synthetic urine works but i had one question. most of the sites directions say to mix before the test. I have random tests but they just leave me alone in the bathroom and i can use the sink with no suspicion at all. could i just carry the powder around with me and just pour it into the cup and mix with warm water?
