Active Ingredient Breakdown
CarnoSyn® Beta-Alanine
Beta-Alanine is one of the most researched performance ingredients available. The CarnoSyn® form used in C4 Sport is the clinically studied version shown to help combat muscular fatigue and support endurance during high-intensity training. You may experience a harmless tingling sensation (called paresthesia) — this is completely normal and indicates the ingredient is active.
Caffeine Anhydrous (135mg)
C4 Sport delivers 135mg of caffeine anhydrous per scoop — a well-calibrated dose that provides a noticeable energy boost without the excessive jitters associated with stronger pre-workouts. Users consistently report feeling effects kick in within 15–20 minutes of consumption.
Con-Cret® Creatine HCl
Creatine is the gold standard in sports supplementation for supporting ATP production, strength, and power output. C4 Sport uses the Con-Cret® Creatine HCl form, which is known for better solubility compared to standard creatine monohydrate.
L-Arginine
L-Arginine is an amino acid precursor to nitric oxide, which supports improved blood flow and muscular pumps during training. It works synergistically with the other performance ingredients in the C4 Sport blend.
Taurine
Taurine is included in the C4 Sport Energy Blend and works alongside caffeine to support focus, mental clarity, and overall workout performance. It also plays a role in cellular hydration.
Electrolytes (Sodium Citrate, Magnesium Chloride, Dipotassium Phosphate)
C4 Sport includes three key electrolytes to help replenish minerals lost through sweat. This makes it a smart choice for endurance athletes, outdoor training, or high-sweat workout sessions.
Vitamins B6 & B12
At 200% and 2500% of Daily Value respectively, these B-vitamins support energy metabolism at the cellular level, helping your body efficiently convert food into usable fuel during exercise.
Other Ingredients (Inactive)
Citric Acid, Natural & Artificial Flavors, Malic Acid, Silicon Dioxide, Calcium Silicate, Sucralose, Acesulfame Potassium, FD&C Blue #1.
Allergen Note: This product is dairy-free and does not contain common dairy-derived ingredients.
How to Use C4 Sport Pre-Workout
- Mix one scoop (approximately 7.1g) with 8 fl oz (240ml) of cold water
- Consume 20–30 minutes before your training session
- Once tolerance has been assessed, you may take one additional scoop before training
- Do not exceed two scoops in a 24-hour period
- Best consumed on an empty or light stomach for faster absorption⚠️ Not recommended for individuals under 18, pregnant or nursing women, or those sensitive to caffeine.
What Workouts Is C4 Sport Best For?
C4 Sport is a versatile pre-workout that performs well across multiple training styles:
- Weightlifting & Strength Training – Creatine and beta-alanine support power output and rep endurance
- Cardio & HIIT – Caffeine and taurine fuel sustained energy for high-intensity intervals
- Endurance Sports (Running, Cycling, Swimming) – Electrolytes maintain hydration and mineral balance
- Team Sports & Field Training – NSF Certification makes it suitable for NCAA and professional athletes
- General Fitness – Beginner-friendly dose of caffeine and clean formula
NSF® Certified Sport — What Does It Mean?
The NSF Certified for Sport® designation is one of the most rigorous third-party certifications in the sports nutrition industry. It means the product has been independently tested to verify:
- The product contains exactly what’s on the label — no hidden or undisclosed ingredients
- It is free from banned substances on major sports organization lists (NCAA, WADA, etc.)
- The manufacturing facility meets GMP (Good Manufacturing Practice) standards
This makes C4 Sport one of the safest pre-workout choices for competitive athletes who undergo drug testing.
Flavor Profile: Blue Raspberry
The Blue Raspberry flavor is widely praised for being vibrant, refreshing, and not overly sweet. Unlike many artificial pre-workouts that taste medicinal or chalky, users describe this flavor as clean, enjoyable, and easy to drink quickly before training. It also mixes smoothly in water with no clumping.
