Whey isolate 1,5 years over date dangerous?

[snowfox]

Hi. I have whey isolate which is about 1,5 years expired. is it still safe to use and does it actually expire when stored in a cool environment? I've already had 8 shakes or so and haven't had any ill effects.

Regarding that (no ill effects), can I assume it's still good to go or does the quality just degrade?

You should be fine... it is certainly NOT dangerous unless you see critters running around in there or moisture got in there

I had a half-empty UN GainFast left in my old home, stayed there two cold winters and three summers, used it one year over expiration, seemed as good as new.
