Cellucor C4 Ultimate Pre-Workout (20 Servings)
by Cellucor
"6g citrulline + 3.2g beta-alanine + 300mg caffeine + Cognizin — Cellucor's top-tier pre-workout with nootropic focus and 8,200+ reviews"
Overview
Cellucor C4 Ultimate is the premium tier of the C4 line, providing 6g L-citrulline, 3.2g beta-alanine, 3.2g betaine anhydrous, 300mg caffeine, 250mg Cognizin (citicoline for focus), and 50mg Theacrine for sustained energy without the crash. The Cognizin citicoline is a patented form of CDP-choline that increases brain phosphatidylcholine synthesis, enhancing focus and mind-muscle connection during training. Theacrine (TeaCrine) provides caffeine-like energy without tolerance buildup — studies show no habituation even after 8 weeks of daily use. The 6g citrulline dose is at the clinical threshold (6-8g), and the 3.2g beta-alanine matches the clinical dose for carnosine loading.
