Well let us know what happened. I'm not 100% sure what will happen but i hope your buddy wasn't drinking a ton of water before peeing for you.
sawtoothwave Reviewed by sawtoothwave on . Substitution method, please help!!! Hello all, I have recently been tested twice now with LabCorp testing. I used the substitution method both times with the same persons pee. The first time I did it, I got the pee the day of and substituted within 5 hours of receiving the sample, I used a wizzinator with a hand warmer and it went off without a hitch, almost. I had my buddy pee in a bottle the next day just in case I had to retake the test for any reason (Thank god I did that) The test came back too diluted and my boss told Rating: 5
