I have 2 questions/concerns regards the above:
1) Is it okay to mix 20 days worth (100iu) with bac water and put it in 1 sterile vial in the fridge or will it deteriorate? My concerns are not just the bac water (I believe this is good for 30days), but also the seal weakening from multiple piercings through the same stopper.
2) Will rubbing the surface of the stopper immediately pre-injection with a swab be a problem? I am thinking of a large guage needle (18) taking alcohol into the liquid from the surface of the rubber I have just wiped.
Appreciate taking the time to read this and look forward to your advice.
