Fast-Acting Energy • No Water Required • Endurance Fuel

The SiS GO Isotonic Energy Gel is formulated to rapidly deliver 22g of carbohydrate per gel, providing a fast, efficient source of energy exactly when you need it most. Designed for intense and prolonged exercise, these gels help maintain performance and delay the onset of fatigue.

Thanks to its isotonic formulation, the gel can be consumed without additional water, reducing the risk of bloating or stomach discomfort often associated with traditional energy gels. This makes it ideal for race conditions and high-intensity training where carrying or consuming extra fluids isn’t practical.

Recognised as the world’s first isotonic energy gel and a winner of the Queen’s Award for Enterprise (2015), SiS GO continues to be trusted by elite athletes and endurance performers worldwide.

The 30-pack format is perfect for regular training, race preparation, and event fuelling strategies.
