Key Benefits of C4 RTD

Explosive Energy

With 200mg of caffeine from anhydrous and natural sources, C4 RTD provides a powerful but smooth energy kick. It’s designed to elevate performance and alertness without the crash, helping you power through workouts or the busiest parts of your day.

Enhanced Endurance

Featuring Carnosyn® Beta-Alanine, a patented version of beta-alanine, C4 RTD helps buffer lactic acid build-up, allowing you to train longer, harder, and with more intensity. That means more reps, less fatigue, and better results.

Increased Blood Flow & Muscle Pumps

With Citrulline Malate or Nitramax™ (varies by version), C4 RTD supports nitric oxide production to enhance vascularity, muscle pumps, and nutrient delivery. Experience that full, pumped-up feeling with every workout.

Sharp Focus & Motivation

Inclusion of N-Acetyl-L-Tyrosine and other nootropic ingredients helps sharpen mental clarity and motivation, ensuring you stay in the zone mentally while you push your physical limits.

Convenient & Delicious
