"Pump" is naturally occurring during resistance training when blood and other fluids are pushed to muscle cells, expanding them. Using ingredients to increase a pump can be a very beneficial way to increase hypertrophy and grow muscle size.
define[pump] increases pump by providing L-Citrulline and Nitrosigine which increase nitric oxide production, allowing for greater vasodilation and bloodflow; Vasodrive-AP which inhibits vasoconstriction; and Glycersize, Betaine, and Sodium which increase intra-cellular hydration (pulling fluid to muscle cells).
define[pump] uses above efficacious doses of all these ingredients at one scoop and the most effective doses at two scoops. These qualities make define[pump] the most ideal supplement to take before a workout for a pump.
