i put some almost boiling water in a balloon to sterilize/warm up the balloon then after emptying it, poured the urine in the balloon. then, on my way to the test, kept the balloon in a thermos with water that was at a slightly higher temp than natural body heat. when i got close to the site, i dried off the balloon and kept it in my bra. i wasnt searched or supervised. im hoping all went well. my friend isnt on any prescription drugs and doesnt do any illegal substances.
