i have a friend who i know is absolutely clean so im probably gonna have him pee for me right before i go in and slap a hand warmer on the pouch that holds the urine. I think im gonna go to this place called any lab test now(they claim to always take no longer than 15 minutes). my biggest fear is the temperature being too hot because i know how hot those handwarmers can get so idk if it would be wiser to just try and use my body to maintain the temperature or use the hand warmer.
