I switched to a different insulin not long ago and I have 24 pens (4 boxes and 4 pens) of 100u/ml Glargine. I’m not going to say where I got them from (I will tell you in person). I just don’t want that info out there but you can probably guess. I don’t need to turn them in so they will just go to waste. Figured I’d try to help a fellow diabetic out.
