I definitely admire the hard work you put into cleansing and self-testing! I usually don't have the time and can't handle the stress of uncertainty. I have always purchased a bottle of QF within a couple weeks of using it but I have read it will be fine stored in a cool place out of the sun. I have on occasion been asked to empty my pockets but not usually. I keep the bottle/heat pad package right up against my jewels under some briefs with another pair of boxers over those for extra warmth lol. I always get stressed going in there but its the easiest thing in the world and it always works. And you could smoke before you went in if you wanted to :rastasmoke:
