Fast Energy • No Water Needed • Performance Fuel

The SiS GO Isotonic Energy Gel is designed to deliver rapid, easily digestible energy exactly when you need it most. Each gel provides 22g of carbohydrate from fast-acting maltodextrin, helping to maintain performance and delay fatigue during intense endurance exercise.

Thanks to its isotonic formulation, the gel can be consumed without water, reducing the risk of bloating or stomach discomfort often associated with traditional energy gels. This makes it an ideal fuelling solution during races, long training sessions, or high-intensity efforts where efficiency matters.

Recognised as the world’s first isotonic energy gel and a winner of the Queen’s Award for Enterprise (2015), SiS GO remains a trusted energy source for elite athletes and everyday endurance performers alike.
