I have to be tested before friday so postponing is out of the question. I did a trial run with water today heated it up in the shower and put it in my junk and at about 1:30 I poured it in a cup and used a digital thermometer to check the temp. It read 93.1 at the highest do you think this will be warm enough to pass? I am planning on wearing two pairs of boxer breifs tomorrow instead of one just to be safe. I read on here that 90-100 degrees is the range, but my cousin said somethin about 94-104 can anyone clarify for me this is just a pre employement drug screening at labcorp if that matters.
