Peak Performance and Hydration
Roctane Energy Drink Mix from GU is an all-in-one solution to energy and hydration with key nutrients like electrolytes and branched-chain amino acids to keep you feeling strong and energized. The precise blend of complex and simple carbohydrates will fuel you up, so you run strong and feel good, longer. Drink one serving every hour to stay energized and hydrated while exercising.
Each 250-Calorie Serving Contains:
Carbohydrates (maltodextrin and fructose) that use non-competing pathways which can help maximize absorption, increase carbohydrate utilization, and diminish stomach distress, so you get energy that kicks in quickly and stays with you.
Sodium, the primary electrolyte lost in sweat that aids in hydration by maintaining fluid balance.
Branched-chain amino acids (L-Leucine, L-Valine, and L-Isoleucine) which may reduce mental fatigue and decrease muscle damage while jump-starting recovery
Taurine can help maintain heart contractility and improve cardiac output during long exercise sessions.
Beta-alanine can help promote formation of the intramuscular buffer carnosine, which can help delay the onset of fatigue during high-intensity efforts.
Features:
Contains 24 servings
Mix with 21 oz of water
Available in Tropical, Lemon Berry and Summit Tea caffeinated flavors
Available in Grape and Strawberry Hibiscus non-caffeinated flavors

I swear by this for any extreme duration rides
Expensive, but a game changer for endurance efforts. My go-to fuel. I mix this and use in a concentrate form so I can carry more with me, extending my ride times to 5 - 6 hours (rather than mixing per one water bottle).

GU BEST THING GOING TO KEEP YOU GOING
I have used GU products since 2000. I find that they are excellent for keeping me hydrated and helping me to not bonk when also using GU gels.

It's fine
Used bonus points to purchase, it seems to work fine for short low intensity rides, but something about it with high temps and intense workouts this stuff doesn't sit well and probably won't purchase again.

This stuff works. Lasting performance.
Love the GU line of products. I use Roctane gels and powders for most rides over 3 hours. It has everything I need. All I do is worry about drinking water (as needed), as I go.

Great product- makes all the difference on a long ride
A little spendy, unless you can get it on sale... but its a greatfast fuel for rides over 3 hours, exactly what your muscles need. I use this form (more affordable than the packets), and mix with water into a 6oz Hammer Flask, then carry 2 or 3 flasks with me as needed. Makes it very easy to consume on the go. Just need a shot every 30 minutes along with water. If I have enough, Ive never bonked with it. Im using Tropical Fruit.

Flavor is pretty good and no problems with digesting 750 ml over an hour.
Like that it has caffeine. For this class of product, the taste is better than Skratch, but I like both. Not bad price for what you get. I can drink a bottle per hour plus some chews with no issues.

Excellent nutrition for looong rides.
Has a good blend of maltose and fructose so it isn't overly sweet. Mixes well with water on a ride, just drop it in and shape it up. I have been using both the caffeinated and regular, both are great for long rides when you need calories and electrolyte replacement.
