The balance of flavors keeps things exciting, and it's definitely a drink you’ll want to keep on hand for those moments when you need an extra kick.

This energy drink is formulated with key components designed to boost your performance and energy levels without the crash that often comes with sugary alternatives.

Review: Worth the try, worth the purchase - I purchased the Cosmic Rainbow flavor C4 Performance Energy Drink. It has Zero Sugar which was very important for me when searching for the perfect energy drink. There is NO Sodium, and, 200mg of Caffeine. The taste of these is literally Skittles in a can but perfectly made to not be overwhelmingly sweet, I am amazed at how they managed to create such a perfect taste with no sugar. Does it actually give me energy? YES. Can I focus with this? Yes, drinking this helps me lock in. Without a doubt, whenever I am not able to muster up the energy myself these save me and get me going. I am not the type to chug an energy drink so my experience with it has been great, no shakes, no crazy increased heart rate, and NO CRASH. Im not sure if they have this flavor with a resealable lid but for someone like me, that likes to take my time drinking energy drinks, that would be a game changer! When I’m drinking this to workout I will drink it while I workout to keep the energy coming (not that the energy isn’t consistent, it is). I noticed that versus other energy drinks the effect of this one lasted the longest and my energy slowly wore off throughout the day, the way natural energy should/would. Whether you’re working out, running errands, at the office, or, just simply trying to make it through the day this energy drink is the answer for the days you can’t find the energy yourself or even just need an extra kick.

## Questions & Answers

**Q: What does the twisted limade taste like? Any favorite flavors?**
A: I find that the Twisted Limeade tastes like a Mountain Dew that has been left out for an hour and isn't quite as "fizzy". My favorite flavor is Frozen Bombsicle (tastes like one of those 4th of July style popsicles), followed by Tropical Blast (tastes like a carbonated fruit punch with heavy tropical notes). The Strawberry Watermelon isn't bad, and tastes just like the name implies, I'm just not a fan of watermelon so it isn't one of my favorites.

**Q: Will this turn me into Bevis and Butthead? Is it really good, worth the $?**
A: They are good like I said I prefer monster 0 cal but these aren’t over the top when it comes to caffeine. I would say try it worth the money.

**Q: How much citrulline is in it**
A: It has 6g of Citrulline.

**Q: Do you sell Fortify energy drink?**
A: C4 does not make Fortify
