- AimsterGreat Taste, Clean Energy and No Sugar Crash!I’m extremely impressed with the Cellucor C4 Performance Energy Drink in the JOLLY RANCHER Green Apple flavor. The taste is spot on sweet, crisp and refreshing without being overpowering or leaving a weird aftertaste. It tastes like the classic Green Apple candy, which is enjoyable to drink before a workout or even during a busy day. I also really appreciate that it is zero sugar, so I don’t feel weighed down or crash after drinking it. With 200mg of caffeine, it provides a strong but clean energy boost that helps me stay focused and motivated through my workouts. The added beta alanine gives the familiar pre-workout tingle, letting me know that it’s working. I love that it is carbonated, giving it a smooth, refreshing feel straight from the can. In a 12-pack it is convenient and a decent value for the quality. I would for sure recommend this to anyone looking for a great-tasting, effective pre-workout energy drink.
- Karthik KalyanPerfect boost and amazing flavorsI bought the 12-pack of C4 Energy Drinks with the four-flavor mix, and I’m honestly so impressed. Every flavor is solid, but the blueberry one completely stole the show for me it’s refreshing, not too sweet, and gives the cleanest kick of energy without any crash. These have been perfect for early mornings, workouts, and those days when I just need that extra push. Great taste, great energy, and definitely worth buying again!
- JamesAmazingC4 is hands-down the best energy drink I’ve tried. The energy boost is fast, clean, and long-lasting without any jitters or crash. The flavors are insanely good — crisp, refreshing, and not overly sweet. I love that it keeps me focused during workouts and gives me that extra push when I need it most. If you want an energy drink that actually delivers, C4 is the real deal!
- Cooper HarronAmazing flavorC4 is amazing. I do absolutely miss the old flavors of twisted limeade and tropical, but this drink is awesome. No aftertaste, and keeps me focused for awhile! There is a slight crash that I experience about 3-4 hrs after finishing. Orange, strawberry watermelon, and cherry are the best flavors to me! But well worth your $$
- NessaGreat pre workoutWhy did you pick this product vs others?:
I’ve been using C4 Pre-Workout, and it’s become a staple in my fitness routine. Whether I’m doing weight training or cardio, it gives me a noticeable boost in energy, focus, and endurance — without feeling jittery or getting a crash afterward.
The flavor I tried (Fruit Punch) tastes surprisingly good — not too sweet or artificial, and it mixes well with water. I usually take it about 20–30 minutes before my workout, and by the time I hit the gym, I feel ready to push harder.
The beta-alanine tingles are real, especially if you’re new to pre-workouts, but they wear off quickly and don’t bother me. I also appreciate that it doesn’t overload you with caffeine like some other products do — it’s a clean, focused energy that helps with performance without making you feel wired.
Whether you’re just starting your fitness journey or looking for a reliable pre-workout to get more out of your sessions, C4 delivers. Just be sure to follow the serving instructions and stay hydrated! - AlesialynetteGreat flavor and great energy!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. It’s the perfect blend of fun flavor and functional energy—ideal for anyone looking to boost their day in a tasty way! - JimBold Flavor and Powerful Energy in One CanMidnight Cherry C4 is hands-down one of the most exciting energy drinks I’ve tried. The flavor hits immediately with a deep, juicy cherry taste that’s bold without being overly sweet. It has that perfect balance of tart and smooth that keeps each sip refreshing and energizing. Within minutes, the C4 energy blend kicks in with a clean, uplifting boost that sharpens focus and powers you through workouts, long days, or late-night projects.
