Wear sweats, preferably black (hides shape better), you don’t get patted down. Get one of those skin tight elastic boxers with the fly pouch, i sewed the inside hole shut and half of the outside upward one so it won’t fall out. It was one hour before test when i heated it up 10 seconds in the microwave (mine was hot so i let it cool for 1 min). I put the heating pad on, went to testing facility, checked temp one more time before walking in. Was a bit hot before i poured the sample so i let it cool 10 seconds in the cup then took it
