The Main Active Ingredient Is: Whey Protein (Concentrate Variant)

Whey protein is a top-notch dairy-based protein used to back up normal muscle upkeep and recovery. This version comes from whey concentrate and delivers a healthy load of essential amino acids, including BCAAs. This blend also includes BCAAs and maltodextrin, which help support muscle repair and energy provision.

What Exactly Does Whey Protein Do?

Whey protein helps to support muscle protein synthesis and recovery when paired with resistance training. BCAAs contribute to this process, with research indicating leucine plays a key role in regulating muscle protein synthesis, as shown by Dr. Norton of the University of Illinois.

This supplement is not intended to diagnose, treat, cure, or prevent any disease.
