Fusion is a multipurpose supplement designed to boost fat metabolism, increase ATP energy levels, and boost VO2 max, making it the first supplement every endurance athlete should consider after a good source of carbohydrates.

Fusion is based on carefully selected adaptogens and natural stimulants that allow you to burn fat and manage weight in a natural, healthy, and efficient way.

Fusion allows you to burn fat in three ways

  1. It boosts fat metabolism to increase your body's ability to burn fat.
  2. It increases oxygen flow (VO2 max) to further improve your training efficiency.
  3. It increases ATP energy levels, which allows you to train harder and burn more fat.

Natural stimulants

Fusion contains natural stimulants that allow you to boost your fat metabolism, increase fat burn, reduce the sensation of fatigue, and improve your athletic performance.

  • Caffeine
  • Green tea extract
  • Cayenne pepper
  • Ginger


Increase your ATP energy levels, reduce exercise-induced stress, and boost your VO2 max with carefully selected adaptogens!

Reduce water retention

Fusion allows you to reduce water retention with dandelion extract. Combined with fat burn, this is the ultimate way to manage weight for training and races.
