Been Using These for Years and Still My Favorite!
I’ve been using these SiS energy gels for years, mainly for cycling, and I really like them. I’ve tried other gels along the way, but I always come back to these.The apple flavor is actually pretty good. It’s not overly sweet or artificial tasting like some of the others I’ve tried. The consistency is another big plus. They’re thinner than most energy gels, so they’re easy to swallow and you don’t feel like you’re trying to choke down a mouthful of toothpaste.Probably the biggest reason I keep buying them is that they’re easy on my stomach. Anyone who spends a few hours on a bike knows how important that is. The last thing you need when you’re 30 miles from home is your stomach deciding it’s had enough!Each gel has 22 grams of carbs, and they’re easy to carry in a jersey pocket. I usually take a few with me on longer rides. They’re convenient, easy to open, and I don’t have to stop riding to use one. I also like that I don’t need to immediately wash them down with a bunch of water.The 30-pack is nice because I go through quite a few of these during cycling season. They’re not necessarily the cheapest gels out there, but I’ve learned that when you find something that tastes good, sits well in your stomach, and works for you, there’s really no reason to mess with it.I’ve probably consumed hundreds of these things over the years, and I’m still not tired of them. That’s saying something!If you’re looking for a good energy gel for cycling, I’d definitely recommend giving these a try. They’ve worked great for me for years, and I’ll keep buying them.

First Time Gel User
Great tasting gels. First time using gels and id heard they tasted terrible, but this one has the taste, consistency, and texture of apple sauce. Great intro to gels. I was amazed at the affect it had on my energy levels during a run. Its just an easy shot and seems to work in about 10-15 mins for me.

One of my go-to gels for long runs.
Work very well for long runs. I also like the fact you don't need additional water to avoid intestinal issues. Flavoring is light, consistency is about the same as hand sanitizer so it's easy to get down.

Excellent taste and quality
My favorite ones, easily digestable, easy to use on the go, very tasty, not super-sweet, which is what you want on those prolonged training sessions.

Easy energy without the usual gel problems
I’ve used SIS Isotonic Energy Gels during long runs, bike rides, and races, and they stand out for one simple reason: they’re easy to take when effort is high.The isotonic formula means no extra water is needed, which makes a real difference during intense or hot sessions. They go down smoothly, aren’t thick or sticky, and don’t leave that heavy feeling in your stomach that many gels do.Energy delivery is fast and noticeable, but not harsh. It’s a clean boost that helps maintain effort rather than causing a spike and crash. I’ve had zero GI issues using these, even late in long workouts.Flavor is light and not overly sweet, which matters when you’re taking multiple gels over time. The packaging is also easy to open while moving.If you rely on gels for endurance training and want something simple, effective, and stomach-friendly, SIS Isotonic gels are a strong option.

Doesn't Taste "Too Anything", Easy to Open
The apple flavor isn't too sweet or candy-like, thankfully. Like you don't feel your teeth are going to instantly rot out when you "drink" this stuff. Seems to work well for recharging on a ride, but if you take in too many of these without something more substantial you're stomach might ache a little. I would prefer that they design the packaging so it's very unlikely the opening will tear off. I had to be super careful not to create two pieces of packaging on my ride (and thus end up littering or risking falling off my gravel bike).

Ok taste felt no difference
I have used many energy gels during my run and used the isotonic one for a half marathon.First off taste is fine and it’s easy to go down but because you don’t really need water to get it down they are bigger then the typical energy gel.So why did i rate it 3. Sadly I found no energy difference after taking them. I followed my plan when to take them so have a burst at the middle and end of the 1/2 marathon and really didn’t feel any difference at all compared to other brands. Yes they have no sugar but still expected some difference like I felt with other brands.Sadly for me didn’t work for me but maybe some they will.

Disappointed returning customer
The box was opened and missing a pack of supplement. I would like missing supplement posted to me. Once received, I will change review.
