Casein is another protein derived from milk, of a lower quality than whey. Some good quality products use it as a third or fourth source, many lower quality ones use it as the primary protein source.

My favorite ON flavor is Rocky Road, mixed in water it tastes like a milkshake. I've had the Vanilla Shake, Double Chocolate, they're good, Cake Batter wasn't a fave, and I just ordered Chocolate Peanut Butter but haven't gotten it yet.
