Vintage Brawn is an all-natural protein powder made from the Big Three proteins used by the Golden Era bodybuilders - eggs, milk (a mix of whey and casein) and beef. It works to build lean muscle faster, reduce muscle atrophy, and speed up recovery.


  • Synergistic Protein Blend: Vintage Brawn's exclusive three-protein isolate formula surpasses the muscle-building and muscle-preserving properties of whey protein - or any single source. By combining different absorption speeds and amino acid profiles, Vintage Brawn's protein blend is more effective, kicks in fast, and lasts for hours.
  • Pure & Potent: Every dose of Vintage Brawn protein delivers a blend of essential proteins from amino acid-rich eggs produced in the USA, milk protein isolate (MPI) comprised of casein and whey sourced from hormone-free New Zealand cows, and USDA grade beef. Together, the Big Three provide you with a complete protein amino acid profile (including BCAA) for maximum muscle growth.
  • Clean, Advanced Formula: Vintage Brawn protein is made exclusively with natural flavors and sweeteners and contains no banned substances. It is a safe and effective protein powder for men and women looking to improve athletic development, strength and fitness.
