Using GU during your regular workouts will keep your mind alert and active, and your muscles going strong. GU gives the most concentrated form of immediate energy with no stomach bulk or distress. It is quickly and efficiently absorbed, and will maintain your blood sugar at the optimal level for a great workout start to finish. This 15-serving pouch is designed for use with GU's Gel Flask to add convenience and reduce waste on long rides.
During a workout or race, no matter what type, you need to quickly absorb carbohydrate-based calories to replace the glucose you are burning at 400 - 600 per hour or you will begin to lose concentration and energy. The fat, fiber and protein found in bars are very slow to absorb and create unwanted bulk in the stomach. GU is created for the body during exercise and, because of its form and ingredients, is absorbed much faster than a bar so you will feel the energy almost immediately.
GU Energy Gel contains maltodextrin, the best complex carbohydrate for delivering energy to working muscles. GU also contains the optimal balance of carbohydrates for the body during exercise: 80% complex/20% simple. It is this balance of maltodextrin and fructose in GU that delivers a quick rise in blood sugar and maintains that glucose level for up to 45 minutes during exercise.
By simply adding GU to your normal workout routine - one serving 15 minutes before starting then another every 45 minutes or so - you will feel strong and energized, be able to maintain your effort throughout the workout, feel better when you finish, and recover quickly for your next workout. If you want to have a good workout you have to supply your body with the right fuel - GU Energy Gel.
Note: Salted Caramel flavor contains 20 mg caffeine per serving.

Vanilla tastes smooth
Im not a gel fan, but this works well when I need a quick sugar hit and can't stomach real food. Vanilla has a light, pleasant flavor with a small dose of caffeine. The resealable package allows small portions (or large ones if you want to fill a flask for long efforts). I just wish Gu offered more flavors in the 15-serving form factor.

Keeps me going!
I have the caramel flavor and I really like it. I carry a squeezable refillable flask with 5 servings and rarely use more than half even on my longest 3+ hour rides. I find eating solid food on a ride will sometimes upset my stomach but this never does. A quick hit every hour or so with a swig of water keeps my energy level steady and prevents me from bonking. The small amount of caffeine in the caramel flavor is nice too. Highly recommended.

flavor lacking in Salted Caramel
The Salted Caramel was tough to get done, I have to mix it with the vanilla that I bought with it. It was a good value on sale but wouldn't buy again in the flavors.

Tasty with a good ratio of fructose to glucose
This large bag size is great for filling a gu flask or an 8 ounce hydropak flask with the gu cap on it for longer rides. Tastes good and keeps the energy up. It is nice to not have a bunch of gel wrappers in your pockets after a ride.

GU Energy Gel keeps me rolling!
Extremely easy to load and carry in a HydraPak, which makes it readily available to use to feed my cycling muscles and keep me rolling through to completing my planned rides. I keep some at my turbo trainer when I'm doing a virtual ride. Love the taste, the ease of use, and general overall quality that directly helps feed my cycling habit

Great for extended rides or runs
This works incredibly well with the hammer gel flask and a ml of coconut water. This makes it easier to eat on the wing. The flavor is nothing to write home about, but it's not bad either. I have purchased it again and again but found it to be fun when you mix in a different flavor when mixing it into the flask, orange, lemon etc.

Keeps you going!!
The Gu flask (and this energy gel) are excellent ways to keep up the calories. Convenient flask can easily be opened and closed on the fly (individual packs can be a pain). The only downside is they can get a bit sticky after a few gulps.

Best value
I'm a fan of GU for providing me everything I need from 2 hour rides to 8 hours. I get these bulk packs and squeeze 4 oz in to a Hammer 6 oz flask, add 2 oz of water, and shake. This gives me a much easier, less messy way to consume on the go. Best value, particularly when these are on sale.

GU Energy Gels are my go-to solution
I prefer GU energy, along with a water bottle. This combo allows me to adjust/respond to my energy level needs without having to commit to a full water bottle consumed. If I need more fluids I can adjust that too, without impacting my energy intake.
And GU makes it easy to dose, every 30 to 45 minutes on longer rides. Flavors are great, get them in single servings or in 15 serving pouches (more affordable), and load it into flask.

Great taste with a little kick!
Love the salted caramel flavor. Has a small amount of caffeine in it, it gives you a pickup without the jitters, so it can be used multiple times for long rides. At the sale price it was less than $1 per serving.

Tastes good, easy to access on bike, prevents a bonk.
Like the taste, used this on a Gran Fondo and it worked. While I used the refuel stops to fill water bottles I didn't need to get food. Spent less time at the restrefuel stops more time on bike, finished faster.

Triathlon training, particularly running, just finished a marathon holding the flask filled with salted caramel. Goes down easy and keeps me from being hungry.

The flavors I have tried all taste good and I still enjoy them at the end of a ride not just at the beginning. Easy to fill the pouch and easy to eat on the go.

Buy only if it's on sale
Stuff works, 'nuff said...but...
At $1serving (the regular price), I don't find particular value in buying bulk. A GU competitor sells their bulk bottles at $0.77serving. The premium GU Roctane is $1.66serving. That MSRP is too steep for me.

love these - quickly able to refill flask for 5 gels worth on each ride
more cost and trash efficient than buying individual gels. I use a hammer flask and refill as I get near the bottom. these always taste great, sweet and salty available. also gives ability to ingest more than 1 serving worth from the flask at once when really needed

The concept is great. The application vessels are NOT, including the Hydroflask...which really isn't good unless you emptyclean it weekly.
