very good protein, and taste FAR FAR better than anything else on the market....BUT....it has quite a few carbs and quite a bit of fat...although they advertise it as good fats, its still got a LOT of calories in it. BUT again its SUCH A GOOD TASTING protein its like having a milk shake when on a diet, it definitely has a place in everyones diet....i wouldn't use it as my main source of protein, but man its fucking delicious
