i was just put the glass of urine directly under an extendable reading lamp, i duno unless the concentrate breaks down under heat i would be pretty interested to see if the concentrate spoils cause i know pee sitting out goes bad fairly quickly, i've experimented with that quite a bit.
RedFury Reviewed by RedFury on . powdered urine to pass test! hey i read on post from another site that you can pass a EMIT drug test (EMIT being the most standard) by using powdered urine, im not talking about the "real" powdered urine advertised on other sites, im talking about real powdered urine from one's own supply. Supposedly what you do is just pee in a glass cup and let it evaporate completely so that all is left is the urine concentrate, you scrape it then mix with with water and supposedly it mixes to the correct color and will pass a test.
