Casein Protein

Build Muscle

Casein is a savvy veteran and an enduring winner. Unlike whey, which is quickly absorbed, casein protein takes longer to digest, feeding your muscles over an extended period of time. It’s also considered anti-catabolic as it supplies a steady and prolonged release of amino acids.

Formula

Supplement with casein

When you supplement with casein, the level of amino acids in your blood and the protein synthesis in your body peak within three to four hours. Because of casein’s slow digestion rate, it is usually recommended for overnight use. This way, you’re putting in the work and chasing your dreams—even when you’re asleep.

BCAAS

SUPPORT RECOVERY

BCAAs are natural born catalysts, those players on your roster who inspire everyone to be stronger. Their job is to boost muscle protein synthesis, to rebuild and grow your lean muscle tissue more effectively. They support rapid muscle recovery from intense training to grow back larger and stronger. Every serving of Casein Protein Plus delivers 5g, to help keep your recovery strong.
