GU Energy Roctane Ultra Endurance Energy Gel, Vegan, Gluten-Free, Kosher, and Dairy-Free On-The-Go Sports Nutrition for Running, Biking, Hiking or Skiing, Assorted Flavors,24-Count

i love to take these on long hikes. i'll take 2 to 3 on 8 hr hikes and they're a great pick me up.not sure on the effectiveness of the amino acids. but i feel great eating these on the go. may be the caffeine

I tried GU Roctane during my full marathon, and I was impressed. The taste, consistency, and flavor are pretty much on par with the regular GU, so if you like that, you’ll enjoy this. I felt good throughout the race—better than usual, actually—until the very end, which is saying something! The only difference I noticed compared to regular GU was that the effects seemed a bit delayed. It took a little longer for fatigue to set in throughout the race. Overall, definitely a solid choice for long-distance endurance. No adverse stomach issues throughout. Definitely swallow with water like normal GU.

Great energy booster during a physical activity. All my tennis friends use it during a match. Within 10 minutes you can feel a boost!

Excellent product. Performs as advertised.

Perfect boost during workout. A bit pricey

Gives you a nice boost when your hustling on the court for hors.

I was a dedicated user of Clif Shot gels, but they stopped making them. I was initially hesitant about the different flavors, but tried them. Each flavor was actually pretty good. They are easy on the stomach and the energy shot you get works for me as a road cyclist.

For a gel, it works great. The flavor is good. It’s smooth.
