does protein got bac? or get stale? I opened a tub a few mths ago to try it then set it aside and finished another jug. would that opened jug be stale? taste bad? be worthless?
Only way to find out is to try it out. If it tastes irregular, dont finish it. Hell, if you got it at GNC you can take it back and get a something new with store credit. I do that all the time.
