Augment reality with BUCKED UP RAW L-Arginine for visible vascularity. Largely responsible for blood flow functionality, this powerful vasodilator powerfully promotes your PUMP by relaxing blood vessels. As a result, encouraging oxygenated blood and nutrients to travel to where you need them most -- your muscles -- when you need them most -- during your workout! Because L-Arginine is such a pivotal part of reaching fitness goals, we included it in our RAW line. It is unflavored, so feel free to mix it with your favorite beverage, or mix n’ match it with any one of our other RAW line supplements to create your own pre-workout.
