Product description
Product Description
About SiS GO Isotonic Gels The SiS GO Isotonic Gel was the world's first isotonic gel effectively delivering an easily digestible and quick supply of carbohydrate for energy during exercise. SiS GO Isotonic Gels are designed to be consumed without water meaning that you can ensure rapid delivery of carbohydrate to your muscles without the feelings of being bloated that can sometimes occur with over-drinking. Why should I take this gel? Depleting your carbohydrate stores during exercise is one of the major causes of fatigue. In addition to ensuring optimal carbohydrate stores before exercise, delivering additional carbohydrate during exercise is known to improve performance, race times and delay the onset of fatigue. As such, SiS GO Isotonic Gels represent a highly practical solution to your in-training and competition fuelling strategy by providing you with a quick supply of 22 grams of carbohydrate per gel. Gels can easily be carried in your pocket or your race belt without the requirement for bulky bottles. Recommended Usage 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.

The first time I used one was during a half marathon attempt, and consumed it over the course of about half a Km around mile 7-8 - These were the perfect boost, light weight, easy to open, and easy to consume, and felt fine on the stomach - the rehydration and extra energy were just about the right amount i had been missing before (it might have been the gel, it may have been the placebo of having something) either way it worked, and i was able to maintain my pace the remaining 5 miles.
Also before use, cut each side in as far as possible without opening them so you can rip the top off without ripping your teeth out.
I took 3 spaced out during my race. Wow managed to finish 15 minutes faster than my projected time. I honestly believe these helped on the day to replace energy towards the end.
Very good flavours as well for me anyway. 👍
I have only consumed two sachets and found their taste to be mildly like the stated flavour. They are, for me, a little sweet in taste.
I’ll need to use them on more hikes to be able to comment on their effectiveness.
Will update after using them again and will be ordering more for future runs till the next marathon.
