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.

On top of that, it's fortified with vitamins like B3, B6, and B12, contributing to overall energy metabolism and keeping you feeling vibrant.

I tried the C4 Performance Energy drink in Skittles flavor and was honestly surprised in a good way. The taste is super sweet—like drinking a mix of all the Skittles at once. I liked it, but it could be a bit much if you’re not into very sugary flavors. As for the effects, the 200 mg of caffeine kicks in quickly. I felt energized and focused without feeling jittery, which made it great before my workout. It also contains beta-alanine, so I felt that typical tingling sensation on my skin, but it was mild and didn’t bother me. The best part? No crash afterwards—the energy lasted for hours and wore off smoothly. Overall, it’s a solid option if you want something sugar-free, flavorful, and actually effective.

it's like a party in a can! The taste is spot on seriously tastes like you're drinking Skittles, but without the sugar crash. 🍬 It gives a nice energy boost, perfect for a pre workout or just when you need a pick me up. 💪 The only thing is, it might be a little too sweet for some people, but if you love Skittles, you’ll probably dig it. ⚡️

Why did you pick this product vs others?: I’ve been using C4 Pre-Workout, and it’s become a staple in my fitness routine. Whether I’m doing weight training or cardio, it gives me a noticeable boost in energy, focus, and endurance — without feeling jittery or getting a crash afterward. The flavor I tried (Fruit Punch) tastes surprisingly good — not too sweet or artificial, and it mixes well with water. I usually take it about 20–30 minutes before my workout, and by the time I hit the gym, I feel ready to push harder. The beta-alanine tingles are real, especially if you’re new to pre-workouts, but they wear off quickly and don’t bother me. I also appreciate that it doesn’t overload you with caffeine like some other products do — it’s a clean, focused energy that helps with performance without making you feel wired. Whether you’re just starting your fitness journey or looking for a reliable pre-workout to get more out of your sessions, C4 delivers. Just be sure to follow the serving instructions and stay hydrated!

I like its flavor; it's very refreshing, and the can makes the drink look very cool. I prefer to drink it during my break at work so I can spend the rest of the day relaxed, with a good attitude, and full of energy. Above all, it hydrates me.
