You did not specify, but if it is preemployment, just substitute with your friends or either use qf, it will not be observed, and you can do whatever you need to do. I will caution you that temperatures are checked and you must be in the range of mid 90 to upper 90's. Recon the place and what the wait time is going to be. Last time I did it I went in a little hot like 100 deg and had to wait about 15 minutes, and the temp dropped to a perfect 98. Everybodies body is different. You will need to practice and see how well your body and concealment method hold heat and rate this in minutes, so that you can provide the sample at temp. I always check it right before I give the sample to ensure that I'm right on temp.
