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.

Good isotonic fuel, packaging good on the go
Didn't work for me - stomach cramps, low energy, almost didn't finish the marathon race.
Great flavour, easy to use, never ad stomach problems.
Gives you a boost just when you're going to need it
Excellent sport training product
Easy to absorb even in hot weather (25-30C).
Definitely give you that needed boost during a race. The thickness of the gel is such that I dont actually enjoy taking them but it’s benefits outweigh that.
Love the new vanilla flavour, tastes great and the gels go down easy without any stickiness left in the mouth afterwards.
Really useful when out on the bike for a quick pick me up. Taste is always great and had no problems to date.
N/a. I can’t review this when I didn’t get any.
Just spot on always gives you that bit extra
Excellent gel with practical wrapper. Have seen other wrappers that keep the removed top connected so does not litter by accident. Please improve.
I can’t be without these gels.. you gotta use them, so you might as well get the ones that taste best, as well as doing the job.
Have used GO isotonic gels for many years now and have found them to be the best
Use Isotonic gels for Manchester marathon along with half marathon races and I never felt depleted in engery. Great product easy to use whilst running and no need for water
Brilliant! tasty and effective. I spread them on my toast before going pout for a ride. Not really, but they really are good - so I'd heartily recommend.
Bought these for my son as got some at a reduced rate as in great north run and he really liked them and felt gave him a boost. Gels I’ve had in past have always made me feel sick but I tried and no sickness with these.
This is by far the best energy gel I have ever used and the Apple flavour is the most palatable one in my option, goes down easily and definitely gives you boost when needed. Have been a client of SiS for 20 years plus so that must say something.
The finisher! At the end of the ride, when exhausted, and yet, you still have to ride home, the apple gel is truly the best.
Don’t know as never actually got the product and still waiting for my refund.
Great product for a quick energy boost
Apple dapple, great flavour
Perfect for my races
Convenient do a great job but relatively expensive.
Perfect Tasting gels
The energy of summer in a small package. Great taste and excellent performance support
Excellent product and service.
Great product & value
Tasty and great boost mid ride
i didn't received my order
For a quick energy boost on the go, these really do work.
Love these, always gives you that bit extra
When you hit a wall and take this wow so much energy . Could not manage with out it
Quite a decent taste
I take 1 gel when I leave the house and find for a 1.5hr ride it's perfect. I have more energy and can work harder for longer. The longer rides I will take 1 -2 geks with me for added confidence.
Great product - love the cherry 🍒
Best energy gels on the market.
Best flavour gel imo. Like a cheery bake well in gel form! No nasty aftertaste.
As good taste as gels get, easy to consume on the go and not too sweet
Easy to absorb. Will use more.
Very good as always
Very good product
Good product,,good price,,all good,,
Great deal, gets me through my mtb rides 👍🏼
This stuff is great. Good price. When u out on a long ride and need some extra energy these are just the job. Easy to use on the the go. Depending on your preference I like them all apart from orange.. But taken at the right times see Google for the timing of them. They are brilliant
I’ve tried the cheapo Wiggle and wasn’t a big fan so reverted back to using these.
V v v v v v god
Amazing taste a good boost for energy
Great product been using them for years
Easy to consume during training and race day. Taste good and give energy within seconds. Easily consume without drinking water 👍
Seem to do the job very well
Use for training/ races half marathon and above. Easy on the stomach and provide the boost, both physically and mentally that is required.
Not quite as nice as the orange but I liked them.
Just what I need for my biking
More jelly like than other similar products.
I love lemon. Tastes perfect
AS described. Works well for me
Good value for money
Does exactly what you want it to do, pleasant tasting, easily digested, instant energy gel in a one dose package, ideal
It's one best around to used when I out on my bike or running
Very useful when running
As a long distance cyclist I always use sis gels, i find the taste good and they are not loaded with sugar like others.
Top notch 👌🏻
I will not write ten characters! You are chasing my feedback too much. Going forward I will buy another companies product.
Great service at a great price.
Great value pack. Instant energy.
does the job good flavour
Like the consistency of the gels, not overly sweet like normal gels.
Used this product while endurance training in Scottish Mountains. Kept my energy levels constant , and when I felt myself flagging I took a gel sachet which restored my energy levels so I could then think straight whilst training in low light and bad weather so kept alert while navigating through tough terrain.
I prefer Apple or Lemon/Lime flavour. But even this is very good during cycling
Good taste and very effective.
not too bad at all for a gel
All very good
Favourite flavour for me 👍🏻
Gotta have em..
Really nice flavour, refreshing and easy to digest
Nice flavour easily taken
Super quality and great service
Nicest gels I’ve tasted
Tastes amazing, just what is needed on long distance run!
