SIS GO Plus Caffeine Gel combines rapidly available carbohydrate with 150 mg of caffeine to support physical energy, alertness and focus during hard efforts. Each 60 ml gel provides 22 g of carbohydrate in a convenient, easy-to-carry format, making it a practical choice for racing, long rides and demanding training sessions.
For shorter, high-intensity events, take one gel around one hour before exercise so caffeine levels have time to rise. During longer events, use no more than two gels per day, keep drinking fluids and consider pairing the gel with GO Hydro or GO Electrolyte when hydration is important. Caffeine can take approximately 30–60 minutes to peak in the blood, so timing matters.
The Double Espresso flavour is vegan, gluten-free, wheat-free, dairy-free and nut-free. Store the gels in a cool, dry place. This product is not intended for children under 16 or pregnant women; if you are sensitive to caffeine, account for your total daily caffeine intake when planning your fuelling.
Ideal for cyclists and endurance athletes who want a concentrated carbohydrate hit with a strong caffeine dose for race starts, late-event fatigue or long, demanding days on the road.
