- Who it's for
- Endurance runners and racers who prioritize stomach-friendly, high-carb fueling on long efforts and ultras. Works well for those following a high-carb nutrition plan who want something easy to consume on the move.
- What people are saying
- Hosts consistently praise the easy-to-swallow consistency, stomach tolerance, and 40g carbs per gel across flavors. Taste is broadly liked, though one host noted an initial Pepto Bismol resemblance before coming around to it.
- Worth noting
- The gel's larger physical size takes up more vest space, which matters on ultras with heavy gel loads. One variant (yellow stripe, Nootropics Beta) contains 200mg caffeine — hosts flag this as easy to confuse with the standard no-caffeine version.

15% off: ROBYNRUNS 40g carb in a small volume. The Neutral flavor has not much/no taste (which I prefer). I empty these into the hydrapac nutrition flasks and the combo makes nutrition SO much easier to get down.

One of my go-to gels for racing. 40g carbs per gel, neutral flavor, thin but not watery consistency that's really easy to get down. No caffeine. I use these in combination with other gels during racing and training. ***WARNING, the Nootropics beta gel has a yellow stripe on the top of the gel and has 200mg of caffeine! (I take 1/2 of one of these late in races)

Goes down so easy. Rotating between orange and strawberry lime.

I take one of these gels every 30-45 minutes depending on the distance I’m running. It keeps me going without stomach issues. I know the presentation is a little big and requires more room in the vest. So if you run ultras, the load could feel a little heavier but totally worth it to carry them.

Did I think it tasted like Pepto Bismol at first? Yes. Is that bad? No! The 40g carbs every 20-40 min during my 100K fueled me to a perfectly executed race. Gentle on the stomach and generally not-based tasting, these are now a tried and true product for me. Thanks, Andrew, for the suggestion!

The GOAT gel. Delicious, 40g carb rocket fuel, with enough sodium to replenish without getting thirsty. I legit look forward to eating these.

SiS gels get mixed into my high carb nutrition plan for the yummy flavors. They're great on my stomach, too, and I feel powered up shortly after taking one. I always get excited when I pull out a SiS gel on my long runs.
