How long will my shakes last in the refrigerator?

If I made some shakes out of say...penut butter, whey powder, and dry baby cerial...how long would they be good for if I let them sit in the refrigerator.

They'll last at least 2 weeks if they are in an air tight container, you might have to give it a quick shake up before you down it though.

I wouldnt wait that long if you are using milk... why do you want to keep them for so long?

I just want to make like a gallon of shakes so that I dont have to make them all day.

I would say its ok to make a gallon if your using water in the shake, though you gotta give it a good shake before pouring so nothing settles

Yea i understand. I don't mind making my 4 protein shakes daily because I can use a shaker cup, but when I start bulking I dont want to have to whip out the blender every day and do dishes.
