C4 Pre-Workout Powder Fruit Punch, 30 Servings — NSF Certified, 135mg Caffeine & CarnoSyn

C4 Sport Fruit Punch is a sugar-free, NSF Certified pre-workout powder that delivers 135mg of caffeine and clinically studied CarnoSyn® beta-alanine to support energy, focus, and muscular endurance for training sessions.

C4 Sport is a streamlined pre-workout designed for athletes and fitness enthusiasts who want reliable stimulant-driven energy with performance-focused ingredients. NSF Certified for Sport testing reduces the risk of banned substances, and the formula’s modest 135mg caffeine offers a controlled boost for early-day sessions or stacked programs. The Fruit Punch flavor provides a classic, fruit-forward taste and comes in a 30-serving tub (packaging may vary).

How quickly will I feel the effects of C4 Sport?

Most users notice increased alertness and a lift in energy within 20–30 minutes after mixing one scoop with water, which is the recommended pre-workout timing. The caffeine delivers a fast pick-me-up while beta-alanine works over repeated use to support muscular endurance.

• Suggested timing: take one scoop 20–30 minutes before training.
• Caffeine amount: 135mg per serving for a moderate stimulant effect.
• Beta-alanine: includes CarnoSyn® to support performance with regular use.

What ingredients are in the formula and why do they matter?

C4 Sport blends performance-focused actives without sugar and with testing assurance from NSF Certified for Sport. The two standout ingredients are caffeine for energy and CarnoSyn® beta-alanine for supporting high-rep work and delaying fatigue when used consistently.

• CarnoSyn® beta-alanine: clinically studied form to support muscular endurance.
• 135mg caffeine: moderate stimulant to improve energy and focus pre-workout.
• Sugar-free base: lower calories and no added sugars in each serving.

Is C4 Sport safe for competitive athletes and drug-tested individuals?

Yes—this product is NSF Certified for Sport, which means it has undergone testing to reduce the likelihood of banned substance contamination. That certification is commonly accepted by many competitive programs, but athletes should always confirm eligibility with their own organization.

• NSF Certified for Sport: third-party screening for banned substances.
• Clear labeling: ingredient amounts and stimulant level (135mg) listed per serving.
• Packaging may vary: formula remains the same despite label changes.

Who is this for: C4 Sport Fruit Punch is aimed at gym-goers, recreational athletes, and competitive trainees seeking a straightforward, sugar-free pre-workout with a moderate caffeine dose and clinically studied beta-alanine. It suits people who want tested ingredients, a familiar fruit flavor, and a formula that works well for strength, circuit, or cardio sessions without an excessive stimulant load. If you’re sensitive to higher caffeine amounts, stacking stimulants, or require strict compliance with sport testing, check with a coach or medical professional before use.
