  Great stuff for cycling

  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.Ver másVer menos

  Works but expensive

  Product is good, and it does make a difference especially on long rides, however I really don't think it's something you cannot make at home for much cheaper.

  Great taste and product

  Very much enjoy the taste, my husband says it gives off kids cold medicine vibes, but I think the grape is more like Gatorade. In terms of performance, think the product works great for efforts over 1 hour, I supplement with other products to get to 100g of carbs/hour but this hasn't give me gut issues!Ver másVer menos
