Reviews
Michael Thompson
“I’ve tried almost every energy drink out there, but C4 Energy stands apart. The Original Arctic Snow Cone flavor became my daily pre-gym ritual—no sugar, no crash, just clean focus. The tingling from the beta-alanine actually makes me feel like I’m ready to take on the weights. My endurance and alertness have improved noticeably, even during long cardio sessions.”
Sarah Lopez
“As someone who works long shifts and trains afterward, C4 Smart Energy has been a game changer. It gives me steady mental clarity without jitters or that wired feeling I used to get from other brands. The natural caffeine feels smoother, and the taste—especially Peach Mango Nectar—is surprisingly refreshing. It’s like productivity in a can.”
Brandon Miller
“C4 Ultimate Energy is my secret weapon before tough workouts. The 300 mg caffeine hit is intense, but in a focused way, not overwhelming. I can power through heavy lifts and still feel sharp afterward. The Starburst collab flavor is a bonus—it tastes amazing for something with zero sugar. C4 is easily the most reliable performance drink I’ve found.”
