  • Great Flavors, fast shipping, but needs better protection when being shipped
Flavor Name: Lemonade Size: 16 Fl Oz (Pack of 12)
I absolutely love the Lemonade! Both the Green Apple Jolly Rancher and Lemonade, are easily my 2 favorite flavors (non-Ultimate). As for the Ultimate flavors? The 2 "WWE" partner flavors are great, but the best of the best is the C4 Ultimate Cherry Bomb Frost, followed by the Wounded Warrior Project Freedom Frost in a very close 2nd. *ONE COMPLAINT* Amazon needs to package these better. I understand how annoying and expensive shipping heavier items can be, and that aluminum cans of carbonated drinks are capable of rupturing (rather easily) while in transit. Nonetheless, adding a little cushion to secure the cans could help. Maybe even using a slightly smaller backs could help too. See the photos to see why I am saying this. ... show more

  • Great flavor and great energy!
Flavor Name: Cosmic Rainbow Size: 16 Fl Oz (Pack of 12)
If you're on the lookout for a delicious energy boost, C4's Cosmic Rainbow flavor is definitely worth a try! This zero sugar drink manages to hit the sweet spot without being overly sweet, making it perfect for those who want a tasty pick-me-up without all the sugar guilt. You'd never guess it’s sugar-free! The flavor is a delightful medley of fruity goodness, reminiscent of a fun summer day. Each sip is like a carnival for your taste buds, with a vibrant blend that really showcases all the fruity flavors. It's playful and refreshing, making it a joy to drink whether you’re gearing up for a workout or just need a little extra energy to power through your day. What I love about Cosmic Rainbow is that it’s not just for gym-goers; it’s great anytime you need a burst of energy. The balance of flavors keeps things exciting, and it's definitely a drink you’ll want to keep on hand for those moments when you need an extra kick. Alongside its delicious flavor, C4 Cosmic Rainbow also packs a punch with its impressive ingredient lineup. This energy drink is formulated with key components designed to boost your performance and energy levels without the crash that often comes with sugary alternatives. One of the standout ingredients is **Beta-Alanine**, known for enhancing endurance and reducing fatigue during workouts. Plus, there’s **Caffeine Anhydrous**, providing that much-needed energy boost to help power through your day or gym session. C4 also includes **Citrulline Malate**, which may help improve blood flow and enhance performance, making it a great choice for pre-workout fuel. On top of that, it's fortified with vitamins like B3, B6, and B12, contributing to overall energy metabolism and keeping you feeling vibrant. What’s even better is that all of this comes without sugar, artificial colors, or preservatives often found in energy drinks. So, you can enjoy the fun and fruity taste of Cosmic Rainbow while fueling your body with quality ingredients.

  • Fuel That Hits Just Right!
Flavor Name: Cosmic Rainbow Size: 16 Fl Oz (Pack of 12)
I’ll be honest—pre-workouts can be hit or miss, but this one actually delivers. I’ve been using the Cellucor C4 Performance Energy Drink in Cosmic Rainbow, and wow… this isn’t your typical chalky or overly sweet gym fuel. It’s fizzy, flavorful, and gets the job done without the crash. The flavor? Straight up addicting. Cosmic Rainbow tastes like a burst of fruity candy, but without the sugar overload. It’s clean, crisp, and surprisingly refreshing. Zero sugar, zero carbs, and somehow still tastes like a treat. No weird aftertaste either—just smooth and satisfying. The energy boost is legit. With 200mg of caffeine, it kicks in fast and powers me through even my most sluggish workouts or long content days. I feel more focused, more motivated, and more consistent in my sets. The beta-alanine gives me that little tingle that says, “it’s go time,” and the BetaPower feels like it helps with hydration and lasting endurance. What I love is that it doesn’t weigh me down. Some energy drinks feel bloated or too intense—this one keeps things light, sharp, and steady. And since it doesn’t have artificial dyes, it feels a bit cleaner all around. Only small thing? The tingle might catch some people off guard if they’re new to beta-alanine—but personally, I dig it. It lets me know it’s working. In short, Cosmic Rainbow is my go-to for crushing workouts, staying dialed in, or just flipping that mental switch on tough days. Always stocked in my fridge—and I don’t plan on switching it up anytime soon. ... show more

  • I like Orange.
Flavor Name: Orange Slice Size: 16 Fl Oz (Pack of 12)
This particular flavor is very hard to find in any retail store and/or gas station. It's one of my favorite flavors, and feel pretty good and alert when consuming this drink. This is my go-to pick since the C4 Ultimate is a bit too much for me, and the Starburst Orange flavor is a tad tart to my liking (still a good flavor). Besides Orange, they have other good tasting drinks in Grape and Strawberry. ... show more

  • Fairly cheap, definitely works
Flavor Name: Strawberry Blast Size: 16 Fl Oz (Pack of 12)
Not a fan of the carbonation. But they are cheap and taste pretty good. Definitely will give ypu a energy boost. The beta alanine may or may not make your skin tingly...depending on your tolerances. Its totally normal. Didn't bother me..just a reminder that it was working.
