C4 Is Well Worth The Price And Tastes Great!
The C4 is delicious. The price was so good I couldn't pass it up. Will be buying more soon in different flavors as well.

Intense and Effective — But Watch the Timing!
The flavor is really good, especially when it’s nice and cold. It goes down easy and actually tastes great. As for the effect? It hits hard! Tons of energy, focus, and that push you need to power through a workout. It definitely delivers.Just a heads-up: don’t take it too late in the day or on an empty stomach. The energy sticks around and can mess with your sleep if you're not careful.What I liked:• Strong, long-lasting energy• Tastes great (Cherry Bomb Frost)• No sugarHeads-up:• Might be too intense for caffeine-sensitive folks• Not ideal for evening workoutsIf you work out earlier and want a serious boost, this pre-workout gets the job done. Just use it smart and enjoy the ride!

Good, but nothing special
I had high expectations of this flavor, and was slightly disappointed. Ive been a fan of the C4 product line for a long time, and I love anything cherry flavored, EXCEPT cough syrup. This cherry flavor was underwhelming. It didnt taste BAD, but it also didnt impress me with a strong cherry taste I was hoping for. I guess I was assuming that the higher price tag meant it might taste better than others and/ or pack a better energy punch. Usually drinks with 300mg caffeine content have me bouncing off the walls and breezing happily through house chores and workdays and whatnot. Didnt get that effect from this, oddly enough. Just got a mild boost. Whatever "tri stim" is, it might as well just be fancy words they print on the can, I dont think it means anything over the basic product. Overall, I still like it, and will continue to buy C4 drinks, just not this flavor.

Effective, Worst Tasting C4 I have Yet to Try.
It tastes like if you took a glass filled with a 50/50 mix of Hawaiian Punch and Robitussin DM and dissolved a couple caffeine pills in it. Yep it's that awful I bought it on sale so I can't cry too much but it makes my face tingle. Hmm the tingle. I like to drink one when I get to the range and start on drills.
