Default Re: Dr. Peterson on how long vials of NPH can be used

well i just started using a new vial the old one i got and started using dec 1st 2011 with no loss of potency that i could tell with 3 pokes a day

the reason i kept it so long is because the numbers were so good and then they started to get a bit wacky got a new bottle still wacky so who knows i could have gone longer i guess .
