Transform your snacking game with the world's best protein shake - Gold Standard Whey. Say goodbye to subpar snacks and hello to a clinically proven formula that helps rebuild muscle tissue, speeds recovery, and limits fat storage. And did we mention the irresistible range of flavours, including Double-rich Chocolate, Strawberry Banana, Cookies & Cream, and French Vanilla Crème? 

  • 24g of protein per serving, powered by Whey Protein Isolate, for muscle growth and repair
  • 5.5g of naturally occurring BCAAs per serving for enhanced endurance and speedy recovery
  • Trusted by athletes worldwide as one of the best-selling and most awarded protein powders
  • Low in fat, sugar, and calories, making it a guilt-free, nutritious choice

Simply blend one serving into 180-240ml of cold water or milk and bask in the indulgent, yet nutritious flavour as your muscle mass skyrockets, recovery times shorten, and excess fat transforms into a source of fuel.
