C4 Smart Energy Drink - Sugar Free Performance Fuel & Nootropic Brain Booster, Coffee Substitute or Alternative | Black Cherry 12 Oz - 12 Pack

This C4 variety pack hits fast in the best way. The flavors are bright and clean, not that syrupy taste some energy drinks have. I usually grab a can when I’m trying to get moving in the morning or when I’m dragging between tasks, and the lift feels sharp without making me jittery. The Cherry Berry Lime and Blood Orange Yuzu are the ones I reach for the most because they taste like a quick splash of something refreshing instead of a heavy drink. What stands out is how clear-headed it feels. I’ll crack one open before answering messages, sorting boxes, or doing anything that needs focus, and it gives just enough push to stay alert without feeling wired. It’s also clutch for long drives or late-night organizing sessions when you need your brain to stay awake but you don’t want coffee sitting heavy on your stomach. Grabbing a can on the go is easy since they chill fast in the fridge. I’ve even tossed a few into my bag when I know I’ll be out running errands all day. The zero sugar thing helps too, especially if you’re someone who doesn’t like sugary drinks slowing you down. No weird aftertaste, no sticky sweetness, just a clean finish that makes you want to grab another flavor and keep moving. With four different tropical mixes in the box, you don’t get bored. Each one has its own vibe, from peachy and smooth to citrusy and sharp. It’s nice having a mix that fits different moods, whether it’s studying, getting steps in, or prepping for a busy day. This pack is one of those things you keep around because it fits into all kinds of routines. A quick boost when you need a lift, something refreshing when you want flavor, and a clean energy feel that doesn’t hit you sideways. It just works.

Very good taste n work pretty good too. Energy level great

decent taste despite being sugar free not too carbonated fairly decent price

Tastes great, gets me going! I will say about half of the time, these drinks come in a box thats already been opened or ripped. Not a deal breaker because everything is as it should. Never had a broken can or a mess to deal with. 200mg of caffeine is just what I need in the middle of a 10 hour shift.

Love this! The flavors are great and the energy is instant and lasts throughout the day.

Love the taste of these drinks! They help me to feel focus and give me energy when I'm dragging in the morning!

These smart energy taste great and as much as I shouldn’t drink that amount of caffeine I really enjoy them. For whatever reason I feel more mental clarity when I drink these.

I find these drinks with the Citicoline-Caffeine combination help me focus. I have ADHD, and my meds motivate me to do something, but don’t typically help me stay on task. C4 Smart Energy really helps me stay on-task and think more clearly about task at-hand. To learn more about the Citicoline-Caffeine benefits, do a web search for "NIH PMID: 25046515", and see the article titled "Improvements in concentration, working memory and sustained attention following consumption of a natural citicoline-caffeine beverage." Really cool stuff.
