I have a large container of Whey Protein Powder that has a March 2022 expiration date but has been open for over a year. How long will whey protein powder typically last once the seal is broken?
Edit: I just mixed up a spoon full in some water and it still taste as nasty as when I first opened it so it should be good to go.
