Product Information

The GO Energy + Caffeine Gel 75mg builds on the established science of the GO Isotonic Energy gel, the world's first and only truly isotonic energy gel.

This product provides 22g of carbohydrate and 75mg of caffeine per gel (Citrus flavour). Ideal for high intensity races and long, tough days on the road. Caffeine has been repeatedly shown to improve performance by lowering your perception of effort by providing a boost just when you need it.

GO Energy + Caffeine is clean in the mouth and easy to digest. For when you want an energy boost, but want the benefits of caffeine too. Use before or during sport for added physical and mental focus when you want to get an edge.

Key Features

  • • 75mg of caffeine per gel
  • • 22 grams of carbohydrate per gel
  • • Formulation delivering energy fast and effectively
  • • Contents: 6 x 60ml gels per pack

Product Uses
Recommended Usage

Consume 1 gel 1 hour before exercise for high intensity, short duration events to ensure the body starts with elevated caffeine levels. In longer duration events consume no more than 2 double caffeine gels per day. Ensure you keep hydrated. This product is not intended for children, under 16's or pregnant women. Where hydration is important, SiS GO Energy + Caffeine Gel 150mg can also be consumed with SiS GO Hydro or GO Electrolyte to ensure a combination of energy, caffeine and fluid delivery during exercise.

Directions for Use

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


Caffeine acts centrally on the brain to lower the perception of effort, which is particularly noticeable in longer events. In distance events over 90 minutes, mental tiredness as well as physical fatigue plays a large role in determining performance as the event progresses. Caffeine can help to maintain physical performance in this situation.

Depleting your carbohydrate stores during exercise is one of the major causes of fatigue. Delivering the additional carbohydrate provided in SiS Energy + Caffeine Gels during exercise can help improve performance, race times and delay the onset of fatigue.

What is the recommended frequency of consumption?

We don't recommend that you consume more than 4 x GO energy + 75mg gels per day.


When is the best time to consume the GO Energy + caffeine Gel?

Have 1 gel 30 minutes before short, intense exercise to provide mental stimulation for the race ahead. Have 1?2 gels towards the end of long, endurance exercise to improve alertness and concentration.


What are the benefits of caffeine?

Caffeine has been shown to increase endurance performance by providing a mental boost, improving alertness and concentration


Are these gels isotonic?

The GO energy + caffeine gel is not isotonic. The added caffeine increases the concentration of the gel.


Will these upset my stomach?

75mg of caffeine is the equivalent to one cup of coffee or one can of energy drink. However, individuals tolerate caffeine consumption differently to others, so make sure you try it out in training, before use in competition.


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.

Makes the headboard bang for hours 💪

Mark Bouch

Love this combination when I really need a boost. Use carefully!


I find these easy to take as the viscosity means they are not too runny, so don’t spill while I take and run, and not too cumbersome to get through, like more solid options such as blocks. The added caffeine definitely gives the boost to push through on long runs without feeling like it’s too much of a chore - exactly what you need for distance training/events.

Rami Khateeb

amazing ...


Chocolate is divine

José Luis García Herrera

A good product!! To the final part of mtb races.


ottimo prodotto per l'allenamento del mattino! occorre intregrare con sali minerali

Steve B.

Great caffeine kick and nice coffee flavour. I love them at mile 16 of a marathon.

Stuart Caton

I don't like coffee, so I wince while ingesting, but it does the job


Ho utilizzato il gel prima dell'allenamento del mattino per 15 km circa di corsa su strada sterrata con leggere salite e discese, ha un effetto energizzante molto buono nella prima fase. Da integrare per gli ultimi tratti del percorso. Discreto il sapore, buona la digeribilità, consiglio di bere un po' di acqua subito dopo assunzione e molta acqua dopo allenamento.

Richard Williamson

Never fails to have the desired effect!


Ottimo soprattutto per la bici sul finale quando si é stanchi da una bella carica per portare a termine il giro

Will Quinn

Always feels like it improves me everytime I'm flagging plus occasionally before I go out !

Daniel Webb

Brilliant to use on a long ride


veramente buono per un carico di energia


A great help with my cycling and running

John Grinham

Nice caffeine hit before an effort or when feeling that 'bonk' coming on.


Good energy and focus




These gels taste like a coffee desert and I have found them to give me a very effective boots at the start of long tough runs when I don’t feel in the mood but the miles still need to get done. I have found the double expresso version quite strong and a full gel might be a little slickly. I normally take half and keep half. These gels have transformed my tough runs and evening runs.

John S

Texture and thickness is easy to take when running. Good size and price and has helped me in many long runs and races. But the tast is defently the let down. Please improve the taste. (may just be the Berry)

stuart king

Me personally do not like berry. But the was no other choice for bundle


Impossibile fare una gara di endurance senza avere dietro uno di questi prodotti con caffeina. Perfetto!


Does a great job at boosting you that extra bit and tastes nice for a gel.
