EF13's All-Natural formula deliver nutrients the body craves. These ingredients have been known to work to elevate natural growth hormone levels, improve muscle mass, increase circulation, and enhance sexual function to support a healthy libido.

Citrulline Malate – known to boost nitric oxide production in the body. Nitric oxide helps increase artery relaxation, which improves blood flow throughout the body during workout. It aids in the promotion, treatment and prevention of many diseases.

L-Norvaline – known to be a powerful antioxidant, but has also been linked to increases in vasodilation which result in dilation of blood vessels, improved circulation and delivery of oxygen to your muscles during intense workouts.

L-Arginine – causes blood vessels to open wider for improved blood flow. L-arginine also stimulates the release of growth hormone, insulin, and other substances in the body.

Whether you are in the gym training, or at the beach hanging, your intense pumps and extreme vascularity will also be there for everyone to notice! The benefit of using Nitric power is a great muscle pump after an intense workout.

The result is a pump that will be more pronounced and will last longer.
