Protein Powder. Multi-Source Protein Blend. Banned Substance Tested + Gluten Free. Fast and Slow Proteins Engineered to Feed Muscle. Extend the Benefits of Protein. Fast & Slower Acting Proteins: Elite XT delivers the muscle building potency of milk proteins, fast acting whey and slower acting casein, to support the development of muscle strength and size in response to serious training. Strategically formulated to deliver 2.2 grams of leucine and 4.5 grams of total BCAAs, Elite XT promotes muscle response whether you’re a beginner or a pro. BCAAs are the muscle-building amino acids that naturally occur in protein, with leucine being the BCAA directly involved in activating muscle protein synthesis. Whey protein is known worldwide as the fastest digesting and absorbing natural protein. Casein is digested more slowly which supports muscle protein building for hours. Elite XT is formulated at a 4:1 ratio of whey to casein which makes Elite XT ideal after tough workouts or throughout the day.
