I've been a C4 user for a while but used some other version off of Amazon. This one is just as good, even better than my old one. It had a salty watermelon flavor and I love salty watermelon.

C4

I've been using C4 Pre-Workout for a few weeks now, and it's definitely one of the best pre-workout supplements I've tried. The energy boost it provides is noticeable right from the first use. Within minutes of taking it, I feel more focused and ready to tackle my workout with intensity. The formula gives me that extra push I need, whether I'm lifting, running, or doing high-intensity interval training. The taste is great — I've tried the fruit punch flavor, and it's not too overpowering, which makes it easy to drink. I also appreciate that it doesn't cause any jitters or crashes like some other pre-workouts I've used in the past. Another thing I love is how it supports endurance. I've noticed that I can push through my workouts longer and with more stamina, which is a huge plus for me. Overall, C4 is a solid pre-workout that delivers on its promises. If you're looking for something to boost your energy, focus, and performance without the negative side effects, I highly recommend giving it a try!

Excellent!

I have been using this watermelon pre-workout for a while, and it works great. The taste is refreshing, and it mixes easily with water. It provides a clean energy boost without jitters or a crash. I feel more focused and motivated during my workouts. Definitely a solid choice for anyone looking for an effective pre-workout.
