SIS GO Isotonic Energy Gel — The Original Isotonic Fuel Gel
The PEAK4 expert team selected SIS GO Isotonic Energy Gel for being the world's first isotonic energy gel, delivering 22g of easily digestible carbohydrate without the need for extra water.

Because it matches the body's natural osmotic pressure, it empties from the stomach quickly, avoiding the bloated, sloshy feeling associated with thicker, syrupy gels that require a water chaser.

An isotonic solution has the same particle concentration as body fluids, which is why SIS GO Isotonic Energy Gel can be consumed without water while still emptying from the stomach quickly.

How to use

Consume 1-3 gels per hour during exercise, aiming for 60-90g of carbohydrate per hour when combined with other fuelling sources.

Format

Box of 30 gels, 60ml each.
