Most recovery takes place at night while you are sleeping. Yet, during this 6-9 hour period, your body is not typically being supplied building blocks that are necessary for growth.  GRUSCO Nutrition's Micellar Casein is slowly digested, so it provides a consistent supply of amino acids for several hours after you drink it. Used every night before going to bed, Micellar Casein aids in the recuperation process, which leads to better performance at your next workout session in the gym.
