I've been told by a mate in the gym, that instead of making one every time I need it, make a load up and leave them in the blender in the fridge. However, someone else disagreed and said it would go off.

Being able to pour it out clean would be easier, but I don't want to be wasting it. Also... Is it better taken with Milk or Water? I've read it is absorbed better with water. Your opinions?
