Pump Addict SF (Pump Addict Stim-Free) is perfect for coffee lovers or those who like to work out late. When you don't need caffeine... but you want an intense muscle pump! SF has two key vasodilators (Citrulline and Agmatine) that increase blood flow, as well as nutrient and oxygen delivery to the muscle, but one of the other key ingredients that make it an incredible pre-workout is the addition of Himalayan sea salt and potassium.
