All if used right: I don't know of any whey protein powder that causes "massive weight gain." in general, weight gain comes from excessive starches &/or fats. Pure protein like whey does not cause this. But one will not have muscle gain just by eating whey- only by exercising as well! i strongly advise whey from grass-fed cows not given hormones & antibiotics, even better if processed at a low temperature.
