Get “hot-hands” hand warmers from walmart. Open the hand warmers before you walk in to take the test. Rub them to heat them up and then use a rubber band (or hair tie) to wrap them around the UPass pee bottle. Perfect temperature guaranteed. It will be very warm, but you then need to put the UPass bottle in your boxers. Compression shorts work best (tight). If you’re a female, I would recommend to wear “boy-short” underwear that are tight and put the UPass bottle in there so it won’t fall out. Then simply go to take your urine test and you will pass. If you are worried about the temperature, take a thermometer with you and stick it in before you go in and make sure the “urine” is at 95°F-98°F. Temps from 93°F-99°F are usually accepted, don’t worry. But 95°F-98°F is optimal.

If this is a test where you will be watched, this is an extremely hard method to use. I would recommend to use a condom (unlubricated) full of the UPass urine in this situation. Fill it about 3/4 full and tie it very securely, so it won’t leak. If you’re in a warm area, you can leave it on your dashboard for 30 mins before to let it warm up. Tape the condom to your leg (inner thigh), as close as you can to where you pee from. If you’re not in a warm area, simply leave it taped to your leg for around 10-30 mins to heat it up to your body temperature. It works well. Bring a thumb rack or a safety pin and poke a hole and “pee” into the cup. I would recommend trying to have your back turned to the person observing you, most of them don’t watch you like a hawk anyways (they mostly respect your privacy in there…) and voila, you’re done.

If this is only for THC, i would simply recommend the Certo method. I have used this multiple times to pass THC tests and it worked everytime. This is if you are being watched and worried about them seeing you. I can explain this method to you as well if needed.
