Pen losing mcg after pinning.
-
My rat Extropy has been using V2 pens for 3mo now and I'm about to upgrade. When she pinch, pin and pray. Extropy lets it sit in her for 10-20 seconds before pulling out slowly. She still notices a drop of peps on the pin tip. She is now using 33G x 4mm, but also it did the same with a 32G. There is a few MCGs lost in every pin. Lately she has been unscrewing the pen reservoir to not lose any more peps. Yes she did use to remove the pen tip but by the time you cap it and unscrew the mcgs add up. It a decent little drop. I didn't mind it, considering it is clear there isn't a backwash into the cartridge. Time to upgrade, "this is the way"...? Follistatin-344 and tesa are not cheap. Please advise.

@martinmarin That's just part of it. My pens do it too. There's always going to be some loss to be expected. I lose 2 units before every pin priming the pen needle to make sure I get my correct dose.
