@carlosmurray706: See this pump? One supplement I keep in my pre workout stack is NOW Sports L-Arginine 1000mg. I use this nitric oxide supplement to support healthy blood flow, muscle pumps, and workout performance. If you’re looking for an easy pre workout amino acid, this is one I use before I train. #LArginine #NitricOxide #MusclePump #dealsforyoudays #GymSupplements
