  • • 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.

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.

Giorgio Colombi

Veramente efficiente

Ian Hutchinson

Reliable for a boost at the end of a long ride or before a race.


high level product to use before or during a workout.

Lynda Chase

These are the best pick me up when you are racing hard in a long event and you start losing it. Best for long running or cycling events but I even have one on a 10 kay where it may only be a psychological benefit.

Great service, good produt


Non poteva mancare

Francesco Cassano

Taste is excellent, and very fluid. I didn't have the chance to try it in the race


Great product to have for those Race events

Peter Steel

Great taste


Seemed to make a difference to my energy levels on a long(ish) training run. The taste was better than I expected too. Not really used gels before, so was pleasantly surprised by the taste, texture and apparent increase in energy levels.

Carl Taylor

Excellent product

Elena/Ezio Marcadella

Great quality!

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.
