C4 Ultimate by Cellucor

It’s a more advanced version of the standard C4 formula, with higher stimulant content and more performance ingredients.

⚡ Key Benefits

🔋 Explosive Energy

• Contains 300 mg caffeine per scoop — a strong dose to increase alertness and power output.

• Some formulations also include Theacrine (TeaCrine®) and stimulant blends to support longer-lasting energy without the crash.

Result: You’ll feel more fired-up and ready to push through tough training.

🏃 Endurance & Fatigue Resistance

• CarnoSyn® beta-alanine (3.2 g) helps buffer muscle fatigue, letting you train harder for longer.

• May cause harmless tingling on the skin (paresthesia) — a common effect of beta-alanine.

💪 Muscle Performance & Pumps

• Citrulline, citrulline malate, and citrulline nitrate (NO3-C™) (total ~6 g) support nitric-oxide production, increasing blood flow and muscle pumps.

• Creatine compounds (creatine HCl and creatine nitrate) help boost strength and power output during short, intense lifts.

🧠 Focus & Cognitive Support

• Includes N-Acetyl L-Tyrosine, Alpha-GPC (A-GPC), and Huperzine A to support mental drive, focus, and mind-muscle connection during workouts.
