Description

Whether you're chasing a personal best or enduring a long-distance challenge, GO Energy + Caffeine Energy Gel helps you stay in control and keep pushing when fatigue hits.

With its isotonic formulation, the gel is designed to be taken without water, reducing the risk of gastrointestinal discomfort. The smooth, refreshing taste and compact 60ml sachet make it easy to consume on the go, whether you're on a run, a ride, or mid-race. Each serving provides 85 calories and zero fat, giving you efficient energy without weighing you down.

Caffeine is a proven performance enhancer, known to reduce perceived exertion and increase alertness. When paired with high-quality carbohydrates, it can help extend endurance, sharpen reaction times, and maintain focus. GO Energy + Caffeine Gel taps into this synergy to help you stay sharp and energised, even when the race gets tough.

Convenient and fast-acting, it's a perfect choice for use before or during demanding sessions, and easily fits in pockets or pouches for quick access mid-activity. Whether you're fuelling for a marathon, triathlon, or a tough training block, this gel gives you the edge to perform at your best.

How does it work

GO Energy + Caffeine Gel works by delivering a precise dose of carbohydrates and caffeine to fuel both body and mind. The 22g of carbohydrate helps restore muscle glycogen and keep your energy levels stable, while 75mg of caffeine stimulates the central nervous system to improve mental clarity, reaction time, and reduce perceived effort. Taken during exercise, it helps you maintain pace, stay motivated, and perform consistently when it counts.

Thanks to its isotonic formula, the gel is quickly absorbed without the need for extra water. This reduces the chance of stomach upset and ensures a steady flow of energy and focus-enhancing caffeine exactly when you need it. It’s a simple, efficient way to meet fuelling guidelines and stay sharp during endurance activities.
