Great Flavor and Plenty of Energy
The Orange Cream flavor is excellent. It tastes like an orange creamsicle without being overly sweet, and it's one of my favorite C4 flavors.The energy boost is strong and long-lasting, making it a great choice before workouts or when I need extra focus during a busy day. Being sugar-free is another big plus, and I like that it doesn't use artificial colors or dyes.Like other C4 Ultimate drinks, you'll likely notice the beta-alanine tingles, especially if you're new to pre-workout drinks, but that's expected.Overall, this is one of the better-tasting performance energy drinks I've tried. Great flavor, reliable energy, and I'd definitely buy it again.

Efficacious but lacking taste
It’s efficacious but the taste is not that great. The energy drink is strong and because it’s strong, it’s got a lackluster taste. I like the drink overall for everything but the taste but you can’t have it all when you need a super strong energy drink for working out. It does get the energy up and the blood flowing to lift heavier weights and give you the juice to push your limits. That’s why I’ll get it again.

Best Energy Drink Available
I absolutely love C4 regular and Ultimate. They are not only delicious, but they give you the kick in the ass to get going. Clear liquid inside, not a bunch of dyes and added chemicals. No harsh crash either. Will always go to C4

DIfferent Formulation 2024
I have been ordering and drinking this rather consistently for the past 8 months, with small breaks in between to curb tolerance (and give the kidneys a breather). This most recent order came with a new can, new formula, different taste. The older one that has BrainBerry is the one I'm used to. This new 3x stem one with teacrine and dynamine does NOT taste the same. It doesn't taste as good. It has a chemically wash over the tongue, with orange cream after taste. If the first one tasted like this I wouldn't have gone for it. Not sure what I'm going to do, but at least I know I can start looking elsewhere.

Yuck.
Didn't even finish the case. The aftertaste is revolting. Other flavors are great but this shouldn't have gone to market . Yuck.
