Hey guys I need to know how long does whey protein stay fresh after opening. I'm not talking about the expiry date of course everybody knows you should consume it before that. I had opened my tub of whey protein about six months ago or so, but until now I had no time to hit the gym and there's 80% left so I can't bear to discard it despite some clumping in the powder.
Thanks for your input cos I can't find any info online they're all referring to the expiry date.
