C4 Ultimate is a high-stim pre-workout powder designed to deliver maximum energy, muscular endurance, strong pumps, and enhanced focus for more intense training sessions compared to the standard C4 formulas. It belongs to Cellucor’s Project Clear Evolution lineup — meaning cleaner label, no artificial dyes or flavors, and fully disclosed ingredients.

💥 Key Benefits

• Contains ~300 mg caffeine per serving — a solid dose for pre-training energy and alertness.

💪 Muscle Endurance & Strength
• CarnoSyn® Beta-Alanine helps delay fatigue and supports muscular endurance (may cause harmless tingling).
• Some versions include creatine or creatine nitrate for strength and power support.

💉 Pumps & Blood Flow
• L-Citrulline or Citrulline Nitrate (e.g., NitraMax®) boosts nitric oxide for stronger muscle pumps.

🧠 Focus & Mental Drive
• Ingredients like L-tyrosine, TeaCrine®, and other focus-supporting compounds help with concentration and mind-muscle connection.

🔋 Vitamins & Electrolytes
• B vitamins (B6, B12) and electrolytes (potassium, magnesium) support metabolism and muscle function.
