think I might have messed one up... I accidentally discharged the water before getting it in the cartridge... I didn't think it would be a big deal bc I thought ill just add my own bac water... Well it turns out I don't think that worked... I Can tell it's not working. The only thing I can think is that the humatrope water has a very distinct smell to it... so maybe thereis something else it needs to dissolve correctly? Idk but this sucks lol
