How much energy does this drink provide and how fast will it work?

Each can contains 200 mg of caffeine which typically produces noticeable alertness within 15–45 minutes depending on tolerance and metabolism. Caffeine provides a straightforward stimulant effect; pairing it with B-vitamins helps support normal energy metabolism.

• 200 mg caffeine per 12 fl oz can for solid daytime stimulation
• Niacin and vitamin B12 to support energy conversion
• Fast-acting when consumed on an empty stomach, onset varies by individual

Is this safe for athletes and drug-tested competitors?

C4 Performance Energy® Cereal Killer is NSF Certified for Sport, meaning it has been screened for many banned substances and is tested for ingredient accuracy. Certification reduces risk but does not guarantee approval in every sporting organization; athletes should still confirm with their governing body.

• NSF Certified for Sport testing reduces contamination risk
• Clear labeling of active ingredients and dosages
• Recommended to verify eligibility with specific athletic organizations

What performance ingredients are included and what do they do?

The formula features CarnoSyn® Beta-Alanine to support short-term muscular endurance and delay fatigue sensations, along with B-vitamins to aid metabolic processes. The product focuses on performance-supportive nutrients rather than calories or sugar.

• CarnoSyn Beta-Alanine for performance-oriented endurance support
• Niacin (Vitamin B3) and Vitamin B12 for metabolic support
• Zero sugar and no artificial colors for a cleaner macro profile

How does the flavor and experience compare to other energy drinks?

Cereal Killer is crafted to mimic a fruity, crunchy cereal taste without the sugar; it leans sweet and nostalgic rather than medicinal. Because it’s zero sugar, sweetness is achieved through alternative sweeteners while maintaining a light mouthfeel unlike syrupy, sugar-heavy competitors.

• Fruity cereal flavor profile with no sugar
• Zero artificial colors for a cleaner appearance
• Carbonated, crisp texture that emphasizes flavor without heaviness

Who is this for? C4 Performance Energy® Cereal Killer 12-pack is aimed at active adults, gym-goers, shift workers, and athletes seeking a robust caffeine boost paired with performance-minded ingredients and independent testing. It’s a good choice for anyone who wants the taste of a cereal-inspired energy drink without sugar and who values ingredient transparency.
