I have a valid batch I got today. From what I have read, This will work. I am more worried about pulling off the deed in the pee room for some reason. I got QF 5.7-1 (I think that is what the box said. Mine is the plus version. I am thinking I will tape it inside my underwear upright then when I pull them down to pee I can simply tilt the bottle and pour it in. Am I right about this? Labcorp will not be watching me or anything right? This is my first time.. Hopefully I pop my SUB cherry the right way. Any advice from a pro would be awesome.
