This PEScience High Volume product is designed to support aspects of exercise performance, particularly focusing on promoting a "pump" sensation during workouts. It features a notable 4000mg of L-Citrulline, an ingredient often used to support nitric oxide production and blood flow, which can contribute to a fuller feeling in muscles during resistance training.
Beyond L-Citrulline, it includes 2000mg of NO3-T (Arginine Nitrate) and 1000mg of Agmatine Sulfate, both ingredients commonly found in supplements aiming to enhance blood flow. The addition of 250mg of Vitamin C offers general antioxidant support, though its primary role here seems secondary to the pump-focused compounds.
A significant portion of the formula is an undisclosed "Performance Pump Matrix" at 3750mg. While the product clearly states its main pump ingredients, the use of a proprietary blend means consumers cannot see the exact amounts of other components within that matrix, which reduces overall ingredient transparency.
