Muscle Matrix contains 25 grams of pure, complete protein powder derived from two different milk sources that digest and absorb at different rates to ignite muscle protein synthesis and keep amino acid levels in systemic circulation elevated for hours; in turn providing the perfect anabolic state for maximizing muscle growth and repair. The whey isolate in Muscle Matrix is rapidly digested and causes robust hyperaminoacidemia (elevated amino acid levels in the blood) that remains elevated after 1.5 hours and returns to baseline after approximately 3-5 hours. These elevated levels increase protein synthesis and anabolism. In contrast, the micellar casein found in Muscle Matrix coagulates in the gut and is digested slower than whey protein isolate. This leads to a slow release of amino acids into the blood which remain elevated for up to 7 hours, thus extending muscle protein synthesis times. In sum these two proteins found in Muscle Matrix protein work together at the right times to help you gain lean mass. Muscle Matrix is suitable for men and women, especially those who partake in bodybuilding. The low carbohydrate content makes Muscle Matrix keto friendly. For best results, drink Muscle Matrix immediately after exercising. Muscle Matrix is available in Chocolate, Vanilla, Cookies and Cream, and Chocolate Peanut Butter.
