    About GO Isotonic Energy Gel Bundle

    The GO Isotonic Energy Gel was the world's first isotonic gel effectively delivering an easily digestible and quick supply of carbohydrate for energy during exercise.

    They are designed to be consumed without water, minimising the risk of being bloated that can sometimes occur with over-drinking.

    Provides you with 22 grams of carbohydrate per gel.


    Winner of the Queens award for enterprise, this innovative product continues to be seen at the forefront by endurance athletes. Use during endurance sessions and events to help avoid flagging.

    Suggested Use

    Depleting your carbohydrate stores during exercise is one of the major causes of fatigue. Delivering additional carbohydrate during exercise is known to improve performance, race times and delay the onset of fatigue.

    The Isotonic formula allows the gel to empty from the stomach quickly as no fluid needs to be drawn into your stomach to dilute the gel, providing fast energy. SiS GO Isotonic Energy Gels are highly practical and can easily be carried without the requirement for bulky bottles.

    Informed Sport Registered

    Suitable For: Vegans, Vegetarians, Lactose free, Gluten Free, Wheat Free, Nut Free, Soya Free

    Directions For Use

    Consume 1-3 gels per hour to deliver approximately 60 grams of carbohydrate and maximize carbohydrate utilization rates. Where hydration is also important, SiS GO Isotonic Gels can also be consumed with SiS GO Hydro or with SiS GO Electrolyte to ensure a combination of both energy and fluid delivery during exercise.

    Simply tear off the top of the packaging and consume - there is no need to mix with water.

    When should I consume these?

    Consume 1-3 gels per hour during endurance exercise to maximise carbohydrate utilisation rates. Alternatively, take one halfway through repeated high intensity exercise (such as football or rugby) to rapidly replenish glycogen stores.


    When should I have these versus Electrolyte, Caffeine or Immune?

    These should be consumed when you need a fast, convenient energy boost. During endurance exercise lasting over 90 minutes, these should be the main gels that are used throughout a race. Use in combination with other Energy products e.g 1 x GO Isotonic Energy Gel and 1 x 500ml GO Electrolyte to hit 58 grams of carbohydrate (per hour).


    Is this gel Isotonic?

    Yes, this gel was the first truly isotonic energy gel.


    Are these 'natural'?

    GO Isotonic gels contain natural flavourings.


    Why are these better than regular foods, for example a banana?

    GO Isotonic Energy Gels are designed to be absorbed fast into your gut, providing fast energy. Some solid foods can take a while to digest as there's more fat and fibre in whole foods, which during exercise can cause feelings of bloating and discomfort.


    Do these contain aspartame?

    No, Gels do not contain aspartame.


    Will they fit in my cycle jersey pocket?

    Yes! All GO Gels are lightweight, compact and designed to fit in jersey pockets, cycle bags and waist packs. They are pressure tested, so don't worry about the packaging tearing or bursting during exercise.

    Had SiS remove my customer details due to poor service. Switching to another brand in response to their inflexible order handling and customer care.

    I like the taste of these and I can use them for longer runs without upsetting my stomach

    Patrick Wadsworth


    Other gels which I have used appear to be just liquid sugar and are quite hard to push/suck out of the container whilst still riding. These you can almost just suck out and finish off with a bit of a squeeze, so much easier to have while on the go.

    Does the job. Tastes pretty good.
