I'm asking because I have this huge jug (powder) of it sitting under my desk that I haven't used for about 4 months. Would it still be okay to start using it again, or should I just junk it and get a new jug?
The thing is, I opened it 4 months ago, used it once or twice, and just let it sit there. I actually forgot it was there since I started another supp. It smells okay to me, but...I dunno, will it still be good?
