What we think

When these gels first burst onto the scene...we knew they were on to something.  We also knew some of the top teams in the world were using it and swore by it's functionality.  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, minimizing the risk of the "full feeling" that can sometimes occur with consuming to much hydration.

How We Use It

We take SIS Energy Gels when we're on the verge of bonking!  Great to stash away in the jersey pocket or in your gear bag for that extra boost when you need it.  Try the caffeinated flavors if you are looking for that extra kick!  Giddy up!

I've tried a few different kinds of gels now including the Gu and Clif brands but the SIS gels are far and away my favorite. I know the texture of these can be a point of contention to some but they're perfect for me. I really love the apple flavor but I even when I bought the variety pack there weren't any flavors that I didn't enjoy. I personally like that they kind of have a gogurt texture that you can easily swallow quickly without any water and I feel like consuming one every hour or so that I'm riding provides sufficient energy. On long rides I usually do also have some Clif Bloks but part of that is I just love the flavor of those as well.

Easy to eat - more like drink. Having a few of these actually act like a drink and therefore you won't need to carry the third bottle with you on long races, grand fondos or rides.

I've used SIS for about a year now. Not loving the taste, but I feel it's an effective product. Hard to describe the texture other than to compare it a bit to Thicket for people with special dietary needs for thin liquids. On a long ride I can feel the caffeine kick in within about 10-15 minutes after consuming. Not as thick or sugary tasting like other gels and I don't need to wash it down with a lot of water like most other gels advise.
