Overview

REDCON1 Big Noise is a stimulant-free pump formula designed to be stacked with any caffeinated pre-workout or used standalone for evening training. The formula provides 4g L-citrulline, 1.5g Agmatine sulfate (inhibits arginase to prolong nitric oxide), and Astragalus membranaceus (traditional vasodilator). Agmatine is the key differentiator — it blocks the enzyme that breaks down arginine, extending the duration of nitric oxide-mediated vasodilation. The stimulant-free design means it can be combined with Total War or any other pre-workout without caffeine stacking concerns.
