What Is SiS GO Energy Powder?

SiS GO Energy Powder is a high-carbohydrate powdered drink designed to provide carbohydrate before or during endurance exercise.

A 50g serving provides 47g of carbohydrate and is mixed with 500ml of water. Science in Sport positions the product for both carbohydrate-loading strategies before exercise and carbohydrate intake during longer training sessions or events.

Maltodextrin and Fructose Carbohydrate Blend

GO Energy Powder uses maltodextrin and fructose as its carbohydrate sources.

Science in Sport's current technical guidance states that the formulation contains approximately 93% maltodextrin and 4% fructose, giving a strongly maltodextrin-dominant carbohydrate blend.

This is different from SiS BETA Fuel 80, which uses maltodextrin and fructose in a 1:0.8 ratio and provides 80g carbohydrate per serving.

How to Use SiS GO Energy Powder

1. Add 50g of powder, approximately three full scoops, to 500ml of water.
2. Shake well until dissolved.
3. During exercise, Science in Sport suggests consuming approximately 500ml every 45–60 minutes.
4. Once prepared, consume within 24 hours.

Science in Sport recommends weighing the powder for the most accurate serving.

For carbohydrate loading, Science in Sport states that up to four servings per day may be consumed with or between meals as part of an overall carbohydrate-loading strategy.
