The SiS GO Isotonic Gel was the world"s first isotonic gel effectively delivering an easily digestible and quick supply of carbohydrate for energy during exercise. SiS GO Gels are designed to be consumed without water meaning that you can ensure rapid delivery of carbohydrate to your muscles without the feelings of being bloated that can sometimes occur with over-drinking. Depleting your carbohydrate stores during exercise is one of the major causes of fatigue. In addition to ensuring optimal carbohydrate stores before exercise, delivering additional carbohydrate during exercise is known to improve performance, race times and delay the onset of fatigue. As such, SiS GO Isotonic Gels represent a highly practical solution to your in-training and competition fuelling strategy by providing you with a quick supply of 20 grams of carbohydrate per gel. Gels can easily be carried in your pocket or your race belt without the requirement for bulky bottles.
