What is Cellucor C4 Sport Pre Workout Powder?

Cellucor C4 Sport is a caffeinated pre-workout powder described as providing energy, endurance, and hydration support for workouts. It contains creatine and beta-alanine, along with electrolytes, and is offered in a Hawaiian Punch flavor. The product data notes gluten-free labeling and the NSF Certified for Sport designation, positioning it as a sport-focused option for athletes.

Gluten safety and certifications

Gluten-free labeling is indicated in the product data, and the NSF Certified for Sport credential is listed among the certifications. However, the complete ingredient list and explicit cross-contact/allergen warnings are not provided in the supplied data, so strict gluten safety beyond the labeling cannot be confirmed from these sources.

Taste, mixability, and use

The Hawaiian Punch flavor is reported as appealing by some reviewers, while others find the flavor overly sweet or polarizing. The product is noted for good mixability with water and provides a high caffeine level (200 mg per serving), which can contribute to tingling from beta-alanine in some users. Experiences vary, with some people enjoying sustained energy and focus and others reporting jitteriness or overstimulation.
