Whey, Casein, Milk

Whey - Increased protein synthesis, enhanced immune function and antioxidant activity, and fast absorption. This is excellent to consume around workout time due to its fast absorption rate. Consume it pre-, during, or immediately post-workout.

Casein - It's slow to digest, clots in the stomach, and appears to be anti-catabolic due to this effect. It contains dairy calcium (which is important for bone health and body comp effects). It should be used at meals (can be combined with other proteins) and at bedtime. It should not be used when trying to accelerate amino acid absorption.
