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. Ideal for tough matches and training sessions. 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 pre-training or match play and at half-time for added physical and mental focus when you want to get an edge.

Key Features

  • 75mg of caffeine per gel (150mg for Double Espresso)
  • 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 30-60 minutes before training or match-play to ensure the body starts with elevated caffeine levels. Consume no more than 4, 75mg 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 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 football match-play where fatigue is high. Mental tiredness as well as physical fatigue plays a large role in determining performance as a game 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 physical performance and delay the onset of fatigue.

When should I use this gel?

Consume 1 gel 30 minutes before an intense training session or 5-a-side and if you want to use during a full 90 minute match consume 1 before and 1 during half-time to ensure you stay on top of your energy levels and fatigue.What is the recommended frequency of consumption?

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



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 SiS 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.


Are they portable?

Yes! SiS GO Energy gels are lightweight and compact, designed to fit in your football shorts, training top or kit bag.

This is my go-to energy gel when I need a real caffeine boost. In my experience SIS isotonic gels help with stomach problems on longer rides. I really like the taste toi!

Martin Dawson

Boosts tired legs in the last quarter of a 100km ride. Tastes great.

Paul Holt

Good product as usual but no label on each gel


Cheaper to buy in bulk, works out to a £1 each ! The gel taste great only draw back is be careful when you put the sachets in your mouth when riding the edges are sharp and if you do remove the sachet from your mouth you can cut the inside of your cheek as I discovered.

Alan Lathbury

Excellent product for the 4 hour rides

Tee Parker

Great texture taste and for me deliver that kick when fatigued


I keep buying these though i don't really like the flavour nor the consistency because they really make you feel good. Hydration is a key point and these Gels kick your hydration up, your energy and your motivation. I recommend them 100%

These are a good alternative in summer to the double espresso gel and they have an excellent citrus taste but the caffeine is a bit on the low side.

Just the same but more expensive than the original version.

William Prewer

Great fuel for the long runs


good service

Nikita Tikhonov

Cola taste is my favorite


Gives al lot of energy


Was surprised at the flavour being as good as it was and how easily it went down. I think an attachment of the rip top opening to the package would be a good idea so it's not getting spat out on the road. Would also get a version of this with more caffeine as the amount in it could easily be increased to double the amount and I'd buy that.

Cool A+++

Roger Ireland

A real boost when you have run out of go after 150 minutes cycling. Returns energy levels to start of ride levels

Mathew stephenson

Great tasting gels if you like your coffee. mid race espresso. . yummy

Caffeine gel is a regular for me especially when I want that quick kick, I find it works fast not lasting as long as some other ISI Gels but for a quick fix fantastic.
