FAQ

What makes the SiS GO Isotonic Gel different from other energy gels?: The GO Isotonic Gel is truly isotonic, meaning it matches your body's natural fluid concentration. It empties from the stomach quickly without needing extra water, unlike standard hypertonic gels which require water alongside them to aid absorption.

How many gels should I take per hour?: Aim for 1 to 3 gels per hour to deliver 22 to 66g of carbohydrates per hour. For sessions over 90 minutes, target 60 to 90g of carbohydrate per hour to maintain blood glucose and delay fatigue.

Do I need water with each gel?: No. The isotonic formula is designed to be consumed directly from the packet without additional water. Continue hydrating separately during exercise using a dedicated hydration product.

Is the SiS GO Isotonic Energy Gel safe for competitive athletes?: All SiS products are Informed Sport certified. Every batch is independently tested against the WADA banned substances list by an accredited laboratory. Suitable for competitive athletes at all levels.
