It may sound crazy but I've passed 4 test note that these are non-monitored test i'm sure there's millions of ways for this but I can't ask anyone I know for their piss they ether smoke or Church going people I use my wife's little Yorkie dogs piss. I put a tarp down and make a dent for a rain catch. Then I use this bottle it holds the right amount I tape it to my groin for about three hours before and it keeps the temp right and I dump. I pass every time no questions asked. I know this sounds fucked up but I get the job...
