from what i know post workout shake are suppose to be drinked as soon as you finish workout when protein absoption is at it's best beside to avoid catabolic state, but i wanted to add 1 cup oat to it but idk since this is a compelx carb which is not absorbed that quick if this willl slow down the whole digestion of the whey protein and the simpler carbs on it or so? making me go catabolic anyways or not absorbing the nutritient fast enough?
