It gives me a clean, intense boost that actually feels like it’s doing something without the crash or jitters. I feel more focused, more driven, and I can push harder in the gym. The BetaPower really makes a difference—I can feel it in my endurance and strength, especially during heavy lifts or cardio. And the flavors? Seriously good. Frozen Bombsicle is my favorite—it tastes like nostalgia and motivation in a can.Then there’s C4 Smart Energy, which is a total lifesaver on my work days. I’m a nurse doing night shifts, so staying mentally sharp is non-negotiable. Smart Energy gives me that focus and clarity I need without making me feel wired.

These taste delicious. You can’t beat the caffeine content and how easy this is to drink. I like the drink mix packets too but nothing beats this because all you have to do is open the can. I take one of these with me every day for work and they fit great in my lunch bag and don’t leak. I count on the focus and energy this drink gives me daily. This is a quality caffeine drink.

Taste great but makes me jittery! Price is comparable to most. Strong carbonation but that’s expected. Lower sugar content which I like. Variety of flavors so you don’t get burnt out on them.

Pros: great taste, energy without a crash, no dyesCons: how healthy really are energy drinks?I was looking for a "healthy" energy drink that I could use to replace my water enhancer and didn't have any dyes. This one fit the bill. Its on the pricier side compared to other options but its not the most expensive one out there. It works without the crash typical of energy drinks. They're carbonated and similar to Sprite in terms of texture. I can't comment on caffeine sensitivity since the only time I was sensitive to caffeine was after I had my son and I initially started drinking caffeine again. Overall, I like these enough to subscribe and save so I'll always have some on hand. As a mom who is the primary parent and works full time with a career, I can't live without some form of caffeine.

C4 black cherry previously my very favorite! This flavor is very great tasting as well! Best value in energy drinks! The NO SUGAR option in C4,s is SUPERB!
