@carlosmurray706: I use NOW Sports L-Arginine 1000mg in my pre-workout routine to support nitric oxide production, healthy blood flow, muscle pumps, and workout performance. After years of training, L-Arginine is still one of my go-to workout supplements. @NOW #tiktokshopstockup #LArginine #NitricOxide #PreWorkout #MusclePump
