GUEnergy Roctane Ultra Endurance Energy Drink Mix, Vegan, Gluten-Free, Kosher, 35mg of Caffeine, and Dairy-Free n-the-Go Energy for Any Workout, 3.44-Pound Jar, Tropical Fruit

Since cytomax was sold to gatoraid and they’re not doing anything with it (thanks Gatorade), I’ve been looking for a suitable replacement. I saw Rocktane and decided to try it.TasteTastes great. Not that sweet. I like sweet in moderation. I typically scrape off buttercream icing off of cakes as it’s too sweet for me. But I’ll eat cream cheese icing with not problem. Grape has a nice subtle taste with just the right amount of flavoring to make it taste light and even refreshing. I cannot stand most energy drinks because they use fake sweeteners or use an ungodly amount of sugar. This has a much lighter taste than cyctomax which I considered very sweet. This seems to have the perfect taste balance for intense or long ridesStomachMy stomach isn’t sensitive. My stomach didn’t feel weird after using this. No gas, no noises…CaffeineWhy are companies adding caffeine? If you’re using this stuff your heart rate is already elevated from your workout. It’s not like you’re going to fall asleep during your workout. Adding caffeine just elevates your heart rate even more. I’m pretty sure I’m alert when I’m working out. This seems to be a bad trend. I’m glad grape has no caffeine.MixThis stuff mixes completely. I use regular tap water, with two scoops in a large cycling water bottle. Shaken, not stirred. Nothing ever settles to the bottom. It remains that way even after 24 hours (left a bottle out). Nice!PerformanceRocktane works although not as great as cytomax. Cytomax had something that made it feel like you were exerting less energy and everything was easier. My legs also burned less during high exertion. Rocktane is much more subtle. It doesn’t feel like I’m breathing easier and while it will never be cytomax, it’s better than hammer (tastes horrible-took one sip and dumped it). It’s also better than c4. C4 endurance seems to pump up your legs more, like you’re weight lifting, so it wasn’t for me. Rocktane does control next day soreness (after a hard workout) but doesn’t eliminate it entirely.All in all, I’m glad I tried this. Ill keep using this until I find something better.

I've been getting back into long distance cycling and wanted to fine tune my salt and calorie intake on long rides. I'm in SoCal so during the summer it's usually 90+ degrees. I usually use Nuun for added sodium and will always drink 22oz of water per hour but I have trouble keeping up with my calories. Regular foods are often hard to handle, carry and digest.This year I wanted to try something different, so I gave GU Energy Roctane Ultra Endurance Energy Drink Mix a try. I just did 60 mile ride with this and it went pretty well. I had a caffeinated flavor and it was a good amount, but maybe I shouldn't have started with a large cup of coffee before the ride. I'm a little sensitive to caffeine now that I've stopped drinking large energy drinks. The taste was fine. I don't know why people complain of the taste, it's on par with the other supplements. It wasn't too sweet either. The calories went down fine and I had no gas or stomach issues. This was a big plus since I'm able to ingest more calories on long rides. Sometimes I don't feel like eating, but drinking this stuff is easy enough.I felt great on the ride and the caffeine was felt for sure. It would have been perfect if not for the cup of coffee I started out with. I never felt weird, I just felt really alert and was not able to take a nap after my ride. Next time I'll skip the fourth drink on the ride.So yeah it's pricey but for long rides it works great.

I used this all the time until my gym started offering a similar option. It's great for endurance, but it is a bit pricey.

I've used this product for runs of up to 50k and it has done the job well. Keeps the energy levels up, no stomach issues, good electrolyte content. As it is maltodextrin-heavy, it is not as flavorful as the caloric content might suggest. One trick which I have employed (do so at your own discretion) is to spike the mix with some grape pre-workout (NO XPLODE in my case) which adds B vitamins, caffeine, aminos, and also enhances the flavor, with the whole mix coming out to roughly the taste of something along the lines of grape Monster.

Bought this to drink for CrossFit it taste so good and helps with my sugar crashes or when I’m doing a competition it keeps me energized and feeling full

I wanted to try Gu roctane but didn't want to buy it the gels. I bought this powder form and I use it before my run. The big box is very good value for money. Honestly I cannot tell the difference between Gu and Gu roctane but maybe there is a difference. The energy levels are usually high 20 minutes after drinking it. Love the Gu brand in general

I feel far less tired after long rides since I’ve been using Roctane. Can’t recommend it too highly. It’s got 250 calories, which is the same as a Cliff Bar, BCAA’s, caffeine, and of course electrolytes. Summit Tea flavor doesn’t have that fruity taste that I don’t care for at all.

GU roctane has been a go to. Great grape flavor. It’s a light flavor too it’s like if you mixed a juice with half water so it was diluted. I use 3 scoops in each bottle. No flavor fatigue and can drink all day.
