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.
- • Truly isotonic formulation - no need for water
- • 22 grams of rapidly absorbed carbohydrate per gel
- • Convenient easy-to-take format
- • Contents: 6 x 60ml gels per pack
- • Flavoured Maltodextrin gel with added sweetener.
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.Product Uses
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.
Directions for Use
Simply tear off the top of the packaging and consume - there is no need to mix with water.
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.

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.

As above great help when strength is getting low
No after taste
Great gels, easy to digest and not too sweet. Packaging is easy to open on the move too.
It fill like apple pulp. Give me a strong power and I can use 5 or 10 and never fil nauseate
Tastes good and works well
Bloody good stuff
My go-to favourite over an extended training session or event
Energy and helps avoid cramping
Perfect for any sport activity
I gel sono molto digeribili e poco dolci per cui non creano problemi quando si prendono anche se si è sotto sforzo. Il gel risponde bene alle esigenze per cui è stato creato, comodo anche da aprire con una mano sola e strappo.
Not as sweet as some of the others and better for it.
Good flavour and easy to use
Lovely flavour & does the job it says will do.
Gusto gradevole e digeribile
ottimo sapore e gel veramente saporito al palato sembra di mangiare un frappè
Sicuramente il miglior gel energetico. Gusto piacevole e nessun effetto spiacevole gastrointestinale
Perfetto very good prodotto nelle specifiche pratico e molto bello ottimo in tutto Consigliatissimo
All right, very good gel!
Does as advertised and tastes good too!
great product as always when you feel you just need that little bit more on a longer ride....
Used these before and they are perfect for that energy kick to get you through exercise
This energy gel gives the boost to my workout, however the sachet is impractical. The tear strip is too tough and won’t tear so you need both hands to squeeze the gel out. You can’t use this ‘one the move’. Likely I’ll switch to Bloks as more practical and less messy. Shame!
Not nice at all
Really good quality and taste.
Refreshing and a change of flavour.
My favourite flavour
Always great products and quick delivery
Again, works well to keep me hydrated (but still prefer vanilla 😉)
Use then when cycling take about 20 mins to take affect but real good & nice flavour
Really good product and reasonable price
Easy to take product which works for me. Nice flavours and easy to swallow on the run.
Stomach friendly portable fuel.
Think I like these best and probably a little too much. Definitely the ones I'll buy again
taste good not too sweet and no chemical after taste
Love the taste and they’re not too thick and gooey
If you like a sweet flavour then this is the ultimate! I love it after a grapefruit one
Great for those long runs. One of the better tasting ones!
My go to product in a refreshing flavour
Really nice, really like the flavour.
Very very nice flavour. I was unsure if they would be too sour or taste too artificial however they taste similar to a cherry yoghurt flavour. Like Black cherry.
Very tasty flavour and good consistency.
It is too sweet for me to use all the time but mixed with the other flavours it works.
Good range of flavours and no need to drink water with these so a great choice for long stretches between aid stations.
Taste great. easy to swallow. my favourite in the isotonic energy gel range.
A bit sweet for me ,but stilllike them
Tasty energy gels
The isotonic nature it the product means one doesn’t have to use extra water to aid digestion- quicker absorption, saving bottles for hydration alone.
Not the flavour for me. Prefer apple or blackcurrant.
My Go to energy gel, easy to consume without too much water
These are second to grapefruit flavour in terms of sharpness.
Excellent, very easy to take whilst on the move. Quickly absorbed.
Good product really helps
Great stuff thanks
Refreshing and effective.
These work for me and this is my current favourite flavour. Good product, good service.
Does the trick and tastes OK, but I prefer the vanilla flavour 😊
No after taste
Used as part of my training nutrition and for my 100 mile charity ride, which was a total success.
best before dates are less than 6 months , they don't give this information on their web sites . 15 days after purchasing, they have done 60% off. Bad price management and poor customers service.
Good, but not as tasty as pink grapefruit
Great on longer rides. Gives a good boost when you start to tire.
Nice orange flavour
Great product, never had an gi issues with it
I have been enjoying the Go Isotonic for years but the bars are new to me and are very good.
Pretty good gels. I find they keep me going on long runs and I don't drink as much water as I should then.
Easy to open and never had any stomach issues.
Go to gel for those longer rides :)
It fill like pineapple pulp. Give me a strong power and I can use 5 or 10 and never fil nauseate

It reminds me Of custard. Pleasant flavour I like it very much.
Delicious! The SiS GO Isotonic Energy Gel is my favourite energy gel by some margin. You can take it without water which is useful and I really notice the improvement in my running times. My favourite flavour is the limited edition rhubarb and custard (no longer available) but this is my second favourite. Recommended!

Loved it- I preferred Rhubarb and Custard and Vanilla but this is really nice too- a welcome change from the usual orange/berry flavours.
Great flavour. Takes your mind off what it is.
Great before the gym or when out cycling.
This flavour surprised me. It was a lot better than I expected. Up there with one of my favourites.
Avoid cramping late in the match with this ...
Always good avoid the bonk make sure you have yours.
Useful but I find the texture cloying and a bit hard to swallow.
Very easy to take and a decent flavour too.
Best out of all flavours love these
Like the taste , still not sure if the gels work for me though
