Great idea, that’s a number one priority for me and reason to buy without any hesitations unless it’s extremely overpriced.

Hi all, Im new to peptide reconstitution, so after my very first time reconstituting and then moving peptide into 3ml cartridge vial for insulin pen, I notice that every time i add new needle for injection i have a lot of liquid coming out without pressing on the pen. Can anyone suggest what I did wrong?
