I usually get the huge jug of Protein Powder... much more cost effective. I had just bought my last jug a few weeks ago, and well ... not even half of it is gone. My ds decided he wanted to make me a protein drink (he's seen me make them before (but I use milk, thank goodness he didn't use milk) and dumped a cup full of water in the jug. I hadn't noticed it until awhile later... so to my surprise, when I opened it, it was clumpy looking? Should I toss it out? Or do you think it is ok to still use? Ayi, yi, yi... what to do?
