About GO Isotonic Energy Gel

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.


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.


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.

Suitable For: Vegans, Vegetarians, Lactose free, Gluten Free, Wheat Free, Nut Free, Soya Free

Suggested Use

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.

Loving these gels. This is the first gel that is easy to take while doing an activity. You don't have to struggle to make sure you get all of the gel and you don't waste half a bottle trying to wash it down. Much smoother than other gels that are like trying to eat peanut butter. And the taste is spot on.

Chris Uber


Best flavor I've tried so far!



I haven’t found a better energy gel that sits so well in my stomach. I can down the entire thing without hesitation.



The best for long runs, you don’t need add water and the flavor is really good

SINDY Almaraz


Amazing gels, basically instant energy, taste great, easy on tummy.

Eric Hanson


Better than Gu, goes down fast without a sticky mess. Worked well in my last century ride



This is a great product - the benefit is almost instant - right now I’m looking for something that’s more like a power bar - the trouble with bars is that they’re hard to get down - too much chewing and too sweet, so your mouth is full of sugar for an hour - if only there was something in between a gel and a bar that was more substantial, but easier to chow down on....



Great fuel, easy to use and fast results

Mark Ferguson


Excellent flavor what I want to change from my two favorites (vanilla and apple)

Christopher Malenab


Works better than the smaller, "GU" style products.



Great taste and easy to get down. What really makes this gel the best is the packet. It's very easy to open on the bike with no mess.

Chris Fulbright


Used them for a while, great for the bike.

Simon Thomas


Truly works and flavor is subtle.

Riamar Tayam


Good flavor, all product have a good taste, no after taste no water need after raking a gel so overall good product

carlos` barrios


Little weak on the orange taste, but it works!!

craig burleigh


I really like these gels as they are easily digested and do not need to be taken with water; my only negative is that I bought a "bulk" pack and they have an exp. date of 02/19. I wish these would last a little longer.



Great product. Great flavor. I use them for very exercise

Cameron Paterson


These gels are the best on the market. Not only do they taste good, they provide the needed energy without destroying your gut.

Anders Dybdahl


Love the taste! Easy and compact for running packs!



Gels are excellent and work for training easy on the stomach

Daniel Corredor


These do the trick. I’m a big fan of this product.

Chris Hepburn


I have used these several times to prevent from bonking. These gels have always occupied a cycling jersey pocket on all of my rides for a quick energy boost.

Hieu Nguyen


The tropical flavor is great. The gels provided a boost and are easy to carry.

Wayne Tucker


Great and easy to use. These work great along with the electrolyte and caffeine gels.

Nic Faure


Love these gels! The flavor is great and the performance is better.

Bryan Prince


Love this product for the simple reason it goes down easy. It’s not thick and gooey like all other gels I’ve tried and you can take it without water which is nice. I bought the cherry without the caffeine and I love it



All I can say is wow. Great flavors with not aftertaste and from a performance standpoint, all my buddies ask what I am using for energy because the improvement is noticeable.



Goes down easy it’s like drinking water.

ALVARO Fernandez


Bought the Tutti-Frutti flavor to see how it taste. I like it so far.
