Ingredient Breakdown
Let's examine the formula that powers one of the world's most recognizable pre-workouts.
Caffeine Anhydrous (150mg)Caffeine is the primary performance ingredient in C4.
At 150mg per serving, it provides enough stimulation to increase alertness, improve workout motivation, and enhance exercise performance without being overwhelming.
For comparison:
- Strong coffee: 95–120mg
- C4 Original: 150mg
- High-Stim Pre-Workouts: 300–400mg+
This moderate dosage is one reason many users searching for a pre workout c4 review find the product beginner-friendly.
Beta-Alanine (1.6g)
Beta-alanine is included to help support muscular endurance.
Many users notice the familiar tingling sensation shortly after consumption.
This sensation is harmless and is one of the most commonly discussed topics in c4 pre workout review side effects conversations.
While the dosage is lower than some research-backed recommendations, it still contributes to workout performance over time.
Creatine Nitrate
C4 contains creatine nitrate, which combines creatine with nitric oxide support.
Benefits may include:
- Improved blood flow
- Better muscle pumps
- Enhanced performance
- Greater workout endurance
Although not heavily dosed compared to standalone creatine products, it adds value to the formula.
Arginine AKG
Arginine Alpha-Ketoglutarate is included to support nitric oxide production.
This ingredient aims to improve blood flow and training pumps during exercise.
While modern formulas often rely more heavily on citrulline, arginine still contributes to the overall performance profile.
