4:1 Endurance Fuel

Custom-Formulated for Protein-Powered Performance

A classic approach to performance fueling—revived with clean, functional ingredients and INFINIT precision.

This ready-to-go Custom Formula is built with a 4:1 carbohydrate-to-protein ratio, designed to deliver balanced energy, hydration, and muscle support for demanding training sessions and long days in the saddle or on the trail. Originally inspired by a discontinued favorite, this blend brings back a familiar formula powered by clean ingredients and complete INFINIT customization.

Protein Powered Fuel

Combining fast-digesting carbs with a dose of complete protein, this formula offers a well-rounded option for athletes looking to:

  • Fuel sustained endurance efforts
  • Support lean muscle during exercise
  • Rehydrate effectively after long sessions
  • Stack workouts with confidence and reduced fatigue

What’s Inside:

  • Multiple Carb Sources – A blend of glucose polymers, maltodextrin, and natural cane sugar to support quick energy delivery.
  • Whey Protein – A complete protein source rich in BCAAs to help buffer muscle breakdown.
  • Essential Electrolytes – Sodium, potassium, magnesium, and calcium to replenish what you lose in sweat.
  • Light & Drinkable – Smooth flavor designed to go down easy, even in the heat of competition.

Perfect for brick workouts, back-to-back training days, long days on the trail, or when you want a little more muscle support in your bottle—this formula is built for the grind and made to help you bounce back stronger.
