I like the flavors with added caffeine, Espresso Love and Jet Blackberry. Taste is fine and they go down easy. The caffeine is 40mg, just enough for a little lift. I've been getting these on Bike Tires Direct sales so the value is good. I have tried a number of other gels. The GU gels are among the ones I keep going back to.

GU brand gels are easier to open and eat while riding than other brands, making them good for races. I prefer the coffee/chocolate flavors to the fruity flavors. For fruity flavors I prefer Stinger brand.

I enjoy the favor of this gel. I picked the cola, and tasted exactly like soda. Easy on my stomach absorbs pretty quickly as long as you take it with water.

I like to get a verity of brands and flavors for my gels to keep things interesting. My latest purchase was the GU mint chocolate. This flavor has a thinner texture than the other GU's. It was great! For very long rides it gets hard to put down some of the thicker GU's, but I can always put down mint chocolate. I like the easy removal tab on GU gels, though it can be tedious to properly dispose of it. The Clif gels have the leash for the tab, though it usually creates another opening.

Gu energy gels are very effective, good tasting and convenient to store in standard cycling jerseys, where they can be easily used while taking a break. I would suggest flavors with higher caffeine content for those that need the extra zip.

Have had several different flavors, rasberry lemonade is still my favorite and closest to actually tasting like the flavor

Try the Double Espresso, great carbs and double caffeine. It's a boost when you need it. Great help on my endurance riding!

On long rides, GU energy gels help me to maintain energy and prevent after ride cramping
Review by Kevin Daly
never used gels in 50 years of riding, wow they are very efficient and maintaining energy levels and Gu was no different than the others i have tried recently. I do however prefer the flavor of the Hammer Gel espresso but thats me.

I was looking for a energy gels that gives me amino acids, sodium, and caffeine in a little pack whenever I go for biking or running. Gu Energy Gels have what I need. Highly recommended!!

I like gels because they are easy and quick !

GU Energy Gels are a great energy supplement. I do as they suggest 1, 5 min. before the ride and another at 45 min into the ride or 1 hr. Been using them for 20 yrs & have yet to bonk if I stay properly hydrated. Any flavor you like will work equally.

These sweet and taste how they sound. I find on longer activities over (3 hours) the gu becomes a bit too sweet. I generally use these as part of a nutrition plan and not by itself. I have rebought the product

WOW! Not only does Gu taste amazing, it also keeps me feeling extremely strong during my races. I always need a good caffeine boost in the middle of races to get me to the end of a hard race, and this gel does the job. I love the variety of flavors that are offered, and this will be an item I continue to use

Take this with me on bike rides and while playing pickleball or hiking.

It doesn't matter how well I eat or how hydrated I am, I'm exhausted after work and the commute home is sometimes awful. If I use Gu and a little bit of water and/or coffee I'm generally able to power through. It's not a guarantee, but I feel much better climbing hills after being on my feet all day.

It's Gu - convenient, tastes good & effective.
I prefer to mix the flavors and carry it in a flask. Hard to beat.
Review by flbikerider
I use a variety of different flavors. This new Lemon flavor is one of my favorites. I will reorder this one as long as it is offered. If you like a non-tart lemon flavor you should give this one a try.

First tried these at an aid station while riding a century. They've been my favorite gel since then. Why? They digest easily, come in a multitude of tasty flavors, and give amino acids, carbs, and even caffeine if you want or need it. I always start with one prior to riding and use one each hour if riding , when not munching on 'real' food.
Tip: use the GU Roctane gel for harder climbs or longer rides. Easy on the stomach, easy to carry, and easy to use while en route. .
