Pro JYM’s three types of protein are absorbed in the body at varying rates of speed – whey extremely fast; casein, very slowly; and egg, at a “medium” pace. This is exactly how you want your protein to act to ensure that the muscles get an immediate supply of amino acids (the building blocks of protein) as well as a steady trickle of them in the hours following.*

Research suggests that when you add medium-digesting and slow-digesting proteins to fast-digesting whey, muscle protein synthesis remains elevated for longer than when using whey alone.* And muscle protein retention is higher, as well.* That means that more protein is being built in the muscle, which is what leads to long-term gains in muscle size and strength.*

1. Pro JYM’s exclusive protein blend extends the process of building, repairing and retaining lean muscle well beyond that of Whey Protein Isolate
2. It takes ample protein to build new muscle and gain strength and recover after hard workouts
3. Whey protein isolate (7.5 grams), micellar casein (7 grams), egg albumen (2.5 grams) and milk protein isolate (7 grams)
4. Delicious flavor
