Prolonged-Release Premium Casein Protein
For decades MuscleTech has been a leading protein brand. Built on a foundation of human research and cutting-edge science, it's earned the trust of countless consumers worldwide. Now the same research and development team has pioneered a new slow-release protein formula based on superior protein sources for longer absorption and better taste.
8-Hour, Sustained Amino Acid Delivery
Enhance your recovery with sustained nutrient release. Casein and milk protein are some of the slowest digesting proteins available. Nitro-Tech Casein Gold delivers 24 g of high-quality protein taken from multiple premium casein sources, including primarily micellar casein. In fact, the protein source used in Nitro-Tech Casein Gold has been shown in research published in The America Journal of Clinical Nutrition to release amino acids into your bloodstream for up to 8 hours after taking it.¹ Because of this sustained-release property, its highly anabolic and anti-catabolic formula promotes a musclebuilding environment for longer periods of time. What's more, each enhanced serving of Nitro-Tech Casein Gold contains 10 g of naturally occurring BCAAs, glutamine and precursor, and only 1 g of sugar. Combined with an award-winning flavor profile, Nitro-Tech Casein Gold is as good for your taste buds as it is for your muscles.
