The Science Behind the Size:

  • Product: a serious multi-stage formula that anticipates the body's needs for pre, during and post-race nutrition.

Stage 1 Defense Complex: Fusion of antioxidants combine to protect muscles during exercise.

Stage 2 Endurance Blend: Beta-alanine supports muscular endurance, power and output; a powerhouse carb blend releases energy faster (waxy maize, glucose), sustains it (maltodextrin), and acts as an energy reservoir to help you finish strong (isomaltulose); electrolyte blend aids proper hydration and helps you overcome heat stress.

Stage 3 Recovery Matrix: Time released whey and casein proteins, at a 4:1 carb-to-protein ratio, help prepare muscles for faster recovery even during activity.

  • Result: sustains optimal performance, enhances endurance and speeds recovery.
  • Science: clinical studies indicate that beta-alanine raises the anaerobic threshold in endurance athletes without any weight gain, it also assists power athletes to delay fatigue; combined with a host of clinically-tested nutrients to enable longer performance and greater output.

No artificial colors - zero fat - clinically tested ingredients.
