Default Re: Insulin and Expiration Dates ?

My opened vial of Humalog is now at it's 70th day and still doing as it should. It sat for about 3 weeks without being used.

I believe clear insulins such as R, Novolog and Humalog have the potential of lasting much longer opened than others where mixing is required.
