Ok, this is a bit strange but Ill ask it anyways. I have a bunch of GHRP-6...I have a slin novo nordisk pen with 2 full novolin toronto penfill cartridges but the slin expired 10/2008 (I know...what a waiste). I am thinking just for the convenience of it I will take the slin out...Wash the vial with some BA (Inject it in and draw it out so its still sterial) then put my GHRP-6 in there and shoot it that way. Not that its that hard to draw up in a slin pin everytime. But I have kids and they dont need to see me shoot...With the penfill it will be a little more descrete. Any thoughs on why that may not be a good/bad idea? I know its not ideal but the pen is easy to tuck in the fridge...
