Nitric Oxide (N.O.) is a cellular gas that causes blood vessels to dilate, engorging the muscles with blood, increasing oxygen & nutrient delivery, and facilitating the removal of metabolic waste products that lead to fatigue. This cascade of events is what’s known as "The Pump."

Consumed in sufficient amounts, Arginine is one of the best, if not the best, precursors of N.O. synthesis in the body. That’s why it’s the cornerstone of Optimum Nutrition's Vassive N.O. Formula-X and why you’ll find a hefty 3-gram dose in every serving. For added effectiveness, Opttimum have also included Citrulline Malate, Histidine, Norvaline, Ginseng, and other pump-potentiating compounds and packed them all into a sustained-release matrix for results that last throughout your toughest training sessions. Other benefits of supplemeting with Optimum Nutrition's Vassive NO Formula X include:

• Sustained Release Delivery System Promotes All-Day N.O. Activation

• Convenient 3-Tablet Serving Size

• No Caffeine

• Part of the Vassive Size & Strength Stack
