hey guys, thanks for any help you can give me, any at all! sorry that i don't contribute to the forum really at all but tbh i don't know s**t about s**t so i'm probably doing y'all a favour so i've come into possession of a pfizer genotropin cartridge of the stuff, but not the pen that goes with it. it's the cartridge of liquid and powder, not yet mixed up, but not the wholeplastic shell and pen that it slots inside. how can i use it without a pen? is it possible? also, can i get these pens without the cartridge inside it somehow in the real world or is it black-market only?
