Bundle Information

SiS Energy Gels

The SiS GO Isotonic Energy Gel was the world's first isotonic gel effectively delivering an easily digestible (to help avoid stomach trouble suffered with many other gels) and quick supply of carbohydrate for energy during exercise.

SiS energy gels provide a fast energy boost with no need for water, in easy to open packaging.

SiS REGO Rapid Recovery

SiS REGO Rapid Recovery is a complete recovery product to be consumed immediately after exercise. It contains a blend of carbohydrate (23g), protein (20g) and electrolytes with vitamins and minerals.

Rapid replenishment of your glycogen stores and the provision of protein helps you to get the most from your training and prepare you for your next session.

Benefits of SiS REGO Rapid Recovery

Carbohydrate is your body's main fuel for moderate to high intensity exercise. During training and competition, our bodies can absorb around 60g of carbohydrate per hour, meaning that demand will outstrip the supply of energy. This shortfall is met by using your glycogen stores, which must be replenished post exercise so you are able to perform well in your next session.

SiS REGO Rapid Recovery contains soy protein, which has a complete amino acid profile to which we have added 2g of leucine to support muscle protein synthesis and rebuild. Leucine is an amino acid which is known to switch on the signalling for muscle protein synthesis, amplifying the affect.
