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.
