THE SCIENCE BEHIND PROVEN RESULTS

Formulated by Former Harvard University Rowers

As teammates on the Harvard Championship Crew team ('04-'06), the founders of Force Factor were looking for a healthful product that would increase both their endurance for long workouts and their strength for sprints. They tested many products. Some were loaded with caffeine and unnecessary additives. Others were just ineffective.

Unable to find the right product, they created Force Factor. The natural elements boosted their energy, endurance, and power. The encapsulated formula provided the perfect balance for their lifestyles.

Ever since Force Factor hit the market in 2009, the founders have been on the hunt for an even more powerful nitric oxide booster. They knew just how well Force Factor worked for the tens of thousands of satisfied customers that had signed up for the free sample, but they refused to settle. They hired some of the country's top researchers to look for the next breakthrough in sports nutrition.

In August 2011, they found it. In a "eureka" moment still ingrained in the minds of everyone involved, the team discovered an incredible new pathway for nitric oxide that is 2x more effective than arginine at raising the body's levels of the key compounds necessary for stimulating nitric oxide production.

This revolutionary finding has shocked the fitness community. The formulators at Force Factor packed every last ounce possible of this game-changing ingredient into the all-new Factor 2, which helps deliver mind-blowing workouts with its cutting-edge, multi-targeted pathway to boosting nitric oxide. The result is amplified strength, an insane amount of power, virtually endless stamina, and explosive energy.

HOW DOES FACTOR 2 WORK?

The Substrate Input Regeneration Complex combines with the Dynamic NOx Enzyme Catalysis System to increase the bioavailability of Factor 2's key ingredient, L-citrulline, powerfully stimulating your body's natural NO production as you conquer your toughest workouts.

Along with Factor 2's powerful amino acids, vitamin C and calcium work in tandem to help increase the amount of nitric oxide synthase enzyme in your body, catalyzing the creation of NO for a continuous release.

The nitric oxide reaction naturally relaxes the smooth muscle cells around blood vessels, widening the inner walls of the arteries. This process enhances nutrient and oxygen delivery to the muscles, increasing strength and endurance while decreasing fatigue during your workouts, giving you ultimate results in the most efficient manner.

REAL PEOPLE. REAL RESULTS.

Gregory AllenReal Factor 2 User

"From the beginning, I truly believed that Factor 2 would help deliver major improvements to my physique in a short time. After taking Factor 2 and getting into a training routine, the results speak for themselves. I picked up Factor 2 from GNC and got to work immediately. The two photos of me show the progress. The first is a photo of me before the transformation, and the second is of me taken today while using Factor 2. Currently, I am over 40 years old, active, and in the best shape of my life."

"I have noticed that even when doing light weight, my muscle fullness becomes larger. I can honestly say I have noticed my biceps being larger than they have ever been. I have also noticed more endurance while running - easier breathing."
