i used synthetic piss once. i was at the lab and put the piss in the cup and came out of the bathroom and gave it to the nurse and she said that it doesnt seem right and she will need another sample and then dumped it into the toilet right in front of me, I was so fucking pissed cause i just spent $50 on that shit. it was body temp and everything. I ended up not getting the job because i told them i cant piss again right away and i tried to leave and they said if i leave i cant take the test again. well i went to a gas station and looked for the smallest bottle i could find which turned out to be a bottle of "bug juice" and i dumped it out, went to a buddies house and made him piss in it, i went back to the lab real fast and they told me i could go ahead wih the test but i had to be watched and i just said fuck you and left.
