THE SECRET IS THE SOURCE OF PROTEIN!

Casein is a slow-acting protein, which results in a more prolonged absorption rate to extend the delivery of amino acids to muscles. Milk protein naturally contains both whey and casein - to provide slow and fast-digesting properties.

Balanced nutrition is important to anyone looking to create a lean, healthy body. One packet provides an excellent source of important vitamins and minerals with a proper balance of carbohydrates, proteins and fats, plus electrolytes. This combination helps keep you on track in and out of the gym.
