If I get the piss right before the test will it still be warm enough once I have to do the test?
Depends on ambient temperatures outside and inside the facility. If the facility has their A/C jacked up way high, you may have to step up on insulating the sub container and/or use handwarmer packs.

You should conduct practice drills with heating, stashing, and pouring - using warmed water in place of urine. As the "sticky" points out, practice is the key to a successful sub...practice, practice, practice.
Burnt Toast Reviewed by Burnt Toast on . U/A in 72 hours I have a UA coming up in 3 days, I was a frequent toker but have been clean for a little over 2 weeks. I am 6'2, 185 pounds and need to know if I will be clean or not for my UA. I have been drinking 2-3 liters of water everyday for the last 2 weeks and sweat on a regular basis. I plan on buying an at home test Sunday to see what it has to say but I was going to check in with the experts for their opinion first. Any advice or suggestions would be appreciated. Rating: 5
