The C4 Performance Energy Strawberry Watermelon Ice is so good. The flavor is incredibly refreshing and not too sweet, making it perfect for workouts. I felt an instant energy boost from the 200mg of caffeine, and it kept me going throughout the day.

So Convenient
These C4 Performance Energy drink mix packets are great. Not only does the Strawberry Watermelon Ice have a nice flavor, but they are such a convenient and easy source of caffeine. I would recommend these drink mixes to anyone who needs caffeine on the go or just a little extra energy prior to a workout.

What sets this product apart for me is its clean energy boost. With 200mg of caffeine and Beta-Alanine, I feel the energy kick without the crash, and it really helps me power through my workouts and busy days. Plus, the fact that it’s zero sugar and free from synthetic dyes makes me feel good about what I’m putting in my body.

Good for anyone who drinks energy drinks
The flavor is pretty good. It actually does taste like orange. To me it kinda tasted like an orange soda but not as strong. I didn’t get a big burst of energy, more like a slow stream that got me where I needed to go. I definitely didn’t feel jittery like some energy drinks. I also had a headache when I drank this and it went away as I consumed more of it. Probably a combination of the caffeine and the hydration. I’d definitely recommend this as an alternative to anyone who drinks energy drinks regularly. It works just as good if not better, tastes better, and ends up being cheaper.

Convenient and flavorful drink mix
I really like these C4 powder mixes, I mixed it with cold water and it had a pretty good taste. It didn’t have that artificial flavor a lot of powdered drink mixes have and it was still flavorful. I don’t feel much of an energy difference after drinking this, but I enjoy these more as a water enhancer and for the taste and it worked well in that way. If you are a fan of the canned C4 energy drinks these will be enjoyable as well with an added benefit of being more convenient on the go compared to the cans. Definitely recommend.

Great tasting!
I think the main thing that comes to mind is that it tastes good. It’s not gritty or doesn’t taste powdery. The flavor is your normal orange drink flavor. I mix it with really cold bottled water, and it does taste refreshing, and it does have the equivalent of more than 2 cups of coffee worth of caffeine. Definitely a caffeine boost. Basically a small hit of good tasting orange caffeine drink on the go.

convenient and deli drink
I’m absolutely loving this Energy Powder Mix in Strawberry Watermelon Ice flavor! The taste is refreshing and fruity, making it perfect for a pre-workout boost or a mid-day pick-me-up. I’ve noticed a significant increase in my energy levels and mental clarity after consuming it. The fact that it’s sugar-free, calorie-free, and made with natural ingredients is a huge plus. The 8-pack is also super convenient for on-the-go use. Overall, I’m highly impressed with this product and would definitely recommend it to anyone looking for a healthy and effective energy boost.

Great Flavor, Too Much Caffeine
I really enjoyed the flavor of this powder and didn’t feel that it tasted like a traditional “zero sugar” product. I’ve had C4 products in the past in the big cans you can get at the gas station and I had no idea a product like this existed. It tasted just like the cans you buy! My only complaint is the amount of caffeine in this product is almost too much. It makes me feel very jittery.
