lg,
well, I used NPH for 12 years before my pump days, and I must say, I never had a vial go bad on me. And I'd leave them out at room temp in my Innovo pen for weeks without it ever being affected. If I were you, I'd maybe start questioning your supplier as to how they store or transport it. And like Heather said, return it!!
Hmmm, I even have 3 vials left in my fridge that've been in there for 4 months now and still look good. Should I send 'em to you maybe lol?!
