Whey Protein

With fast digestion, Whey Protein is the type of protein most commonly used by athletes. Although Whey Protein shakes can be used throughout the day, the "30 Minute Window" post exercise is the ideal time as your lifted metabolism transports the protein to the muscles faster than usual. We have 4 flavours of Whey Protein (Chocolate, Vanilla, Pineapple & Coconut & Strawberry) and 3 flavours of Advanced Isolate + (Mint Chocolate, Chocolate Orange & Strawberry) - a more purified version of whey protein - all available in 1kg tubs.
