| My first endo was a MD/PhD and he talked to me a bit about his research lab work because I was currently working my way towards a PhD in microbiology. He said that they use expired insulin in his lab well past the expiration date and that it retains it's activity (as long as it is stored properly). Of course the lab is not real life, and the safest thing to do would be to get a new vial. Your doctor may even have a sample vial he could give you. |
