@carlosmurray706: I’ve tried a lot of supplements over the last 25 years. NOW Sports L-Arginine 1000mg is one I still keep in my pre workout stack. I use this L-Arginine nitric oxide supplement to support healthy blood flow, muscle pumps, and workout performance. If you’re looking for an easy pre workout supplement, this is the one I reach for before I train. @NOW #LArginine #NitricOxide #PreWorkout #MusclePump #GymSupplements
