Product Information

The GO Energy + Caffeine Gel 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 up to 150mg of caffeine per gel (dependent on 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

  • • Up to 150mg of caffeine per gel (dependent on flavour)
  • • 22 grams of carbohydrate per gel
  • • Formulation delivering energy fast and effectively
  • • Contents: 20 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.

Best product out there


I participate in full & half marathons every year and greatly rely on these gels through my runs. There are many gels out there but the gels by SIS work so well that I swear by them & are always with me when I do my marathons. The gels also taste good with many different flavours & provide the right amount of energy that I need to help me through my runs.
