I may or may not have a test the 29th

Im on probation and am "randomly" tested. I was clean the first 6 months of my probation but i finally said wtf im a good kid and fvck the gov for making someone like me even have to deal with this nonsense.

k well my next visit is the 29th. ive only gotten tested once so far and i was in the bathroom alone. Odds are i wont even get tested. i plan on cleanin a condom and havin my buddy piss in it for me and take it with me.. My concern is the temp. ive read so many conflicting things before coming here so i figured id just ask the pros

He will be able to meet me outside my probation place in the parking lot. I should see my PO within 30-45 minutes of obtaining his piss. If i tape it under my nuts should i be fine? I was also thinkin maybe just insulating the condom with a sock or something and putting in my pocket. or putting handwarmers around the condom. But i feel like the temp should be fine if i can get the urine in the cup with in an hour am i right?

Additionally i have stopped smoking but my usuage up to now has been pretty heavy for the last two weeks. I am exercising drinking cranberry juice/water im pretty skinny and i dont feel its completely impossible to be clean in 11 days for me and i will take my own test to see beforehand but anyways any suggestions are appreciated. i basically just want to kno if the temp should be ok
