C4 Original is a pre-workout supplement designed to support workout energy, muscular endurance and pumps, with 150 mg of caffeine and 60 servings in Icy Blue Razz.
Pre-workout supplements are made for people who want a prepared option before a training session. C4 Original combines caffeine with ingredients formulated to support endurance, strength, performance and pumps. Its directions make it suitable for pre-training use, whether you are beginning a fitness routine or working toward a new performance goal.
C4 Original is formulated to support energy, muscular endurance, strength and performance during workouts. Each serving supplies 150 mg of caffeine, while CarnoSyn® Beta-Alanine is included to help combat muscular fatigue and support endurance. Studies have linked benefits from CarnoSyn® Beta-Alanine with cumulative use, so this ingredient is associated with ongoing use rather than a guaranteed immediate result. Beta-alanine may cause a harmless tingling sensation.
The formula also combines creatine and nitrates in a patented blend designed to enhance pumps. A super creatine compound is included to support strength and performance. A separate patented, clinically studied compound may help the body prolong its buildup of caffeine tolerance. These ingredients give C4 Original several training-focused functions in one pre-workout formula.
Mix one serving of C4 Original with 6 fl oz (177 mL) of water and take it 20–30 minutes before training. The formula is sugar-free and is intended to be prepared as a drink before your workout. Follow the serving amount and timing given for this product.
Caffeine provides the formula’s stated energy support, with 150 mg in each serving. The other ingredients are included for complementary training goals: CarnoSyn® Beta-Alanine for muscular endurance and a creatine-and-nitrates combination for pump support.
