How much caffeine is in a C4 Extreme?
For those looking for a significant energy boost to power through intense workouts, C4 Extreme delivers with a robust 200mg of caffeine anhydrous per serving. This is a higher concentration than the standard C4 Original, targeting users who have a built-up tolerance to stimulants or require a more potent kick. Caffeine anhydrous is a common ingredient in pre-workout supplements, known for its ability to rapidly increase alertness, focus, and energy levels, helping you to feel more motivated and capable of performing challenging sets.
Key ingredients and performance effects
While caffeine is the primary energy driver, C4 Extreme's formula contains a blend of other active ingredients that work synergistically to enhance your workout. The transparent label ensures you know exactly what you are consuming.
- CarnoSyn® Beta-Alanine: A clinically studied ingredient included at a 2g dose to help increase muscular endurance and combat fatigue during your training session. It is also responsible for the harmless tingling sensation known as paresthesia that many users experience.
- Creatine Nitrate (NO3-T®): This ingredient, bonded to nitrate, supports powerful muscle pumps and overall performance. Creatine is well-known for increasing strength and muscle mass.
- N-Acetyl-L-Tyrosine: Included to support enhanced mental focus, helping you stay sharp from the first rep to the last.
- Citrulline Nitrate [as NitraMax (NO3-C)™]: Aids in supporting powerful pumps and performance by increasing nitric oxide production, which in turn improves blood flow to working muscles.
Comparison: C4 Extreme vs. Other C4 Pre-Workouts

| Product Name | Caffeine per Serving | Target User Profile | 
|---|---|---|
| C4 Extreme | 200mg | Intermediate to advanced users seeking explosive energy and enhanced performance. |

Usage and safety considerations
To use C4 Extreme, mix one level scoop with 6 fluid ounces of water and consume it 20–30 minutes before your workout. It is important to assess your tolerance, as the 200mg of caffeine is substantial for those not accustomed to high-stimulant products. The manufacturer advises against combining C4 Extreme with other caffeine sources, such as coffee, tea, or soda.
It is also recommended to cycle off the product after 8 weeks of continuous use to prevent dependency and allow your body to reset its stimulant tolerance.
Potential side effects of pre-workout supplements can include:
- Jitteriness or anxiety
- Increased heart rate
- Headaches
- Digestive issues
- The aforementioned tingling sensation from beta-alanine
Always consult a healthcare professional before starting any new supplement, especially if you have pre-existing medical conditions, are taking other medications, or are pregnant or nursing.
