Build more muscle and strength each two-scoop serving of six star casein protein delivers 50 gram of protein, including slow-digesting casein, which helps feed your muscles with a continued flow of amino acids (the building blocks of muscle). Plus, it's enhanced with an added ingredient that's clinically shown to build more muscle and strength. Powered by 100 percent sustained-release casein protein 100 percent of the casein component in new six star casein protein is high-quality casein protein, which is a slow-release form of protein and is rich in amino acids. This makes it perfect to take between meals and before bed. Prolonged amino acid delivery before bed research has shown that casein protein has a slow absorption rate into the bloodstream, which results in sustained amino acid delivery. The slower digestion and delivery helps feed your muscles with a continued flow of powerful amino acids. Take six star casein protein between meals and before bed. Build more lean muscle plus, it features another powerful, university-studied key compound shown to help build more lean muscle. It's perfect for anyone trying to build a better body.
