SiS GO Isotonic Energy Gels

Best Gels

I’m usually a maple syrup girl, but when it comes to actual gels, SiS is a favorite. They are thin enough that I don’t choke them down. The flavors are pretty good, and they are easy on my stomach.

Easy on stomach!

This was my first time trying SiS gels after trying every brand you can think of. These are by far my favorite and I'm never going back to anything else. Texture is great and flavor isn't too strong, so these go down super quick and easy. I've struggled with GI issues on runs. I was advised by my RD to give these a try and...no emergency bathroom stops!!!

Great Price, Great for Shorter Long Runs

I tried this product as a less expensive alternative to hydrogels. The flavor is mild, and this works great for runs of two hours or less. I find that my sensitive system needs the more sophisticated hydrogels beyond that point. This is a great supplement to pair with my more expensive fueling products.
