You would have to do some practice drills to see if your body heat alone can keep the sub at proper temp without the handwarmer pack.

3 oz of sample is more than enough. Even 2 oz is. The collector may ask for more, only to discard the excess. Asking does not always mean receiving. Under DHHS regs, if 2 oz is all the donor can submit, the collector has to accept the sample.
