If I pre-mixed a gallon of protein shake and kept it in the fridge, will it lose it's potency? Or do I have to make it right before it's consumed?
Also, how do you take the lumps out? I use a portable mixer, but there are still lumps in the drink..
try a shaker bottle. thats what i use and mine is smooth as silk (if silk was chocolate mint flavored, with 23g of protein and made by optimum nutrition)
