What Is Pro Factor X?

Pro Factor X is an energizing, totally natural pre-workout supplement that raises your body’s levels of nitric oxide (NO2) and free (active) testosterone for major bodybuilding and sports performance improvements. This carefully formulated fitness aid enhances your efforts to build more lean muscle mass while strengthening your entire skeletal muscle structure, improving your athletic speed and agility. It supplies your system with lasting energy bursts and stamina that will enable you to finish more strenuous, demanding gym workouts and sports games without suffering from signs of fatigue or exhaustion.

The health-promoting formula of Pro Factor X increases your circulatory activity as well as your metabolic rates, both of which support better sports action and results. With improved blood circulation throughout your body, your skeletal muscles will be well-fueled and empowered to support you during faster-paced, intensive sports action. You will also experience faster, deeper breathing during athletic practice and competitions, finding that you have the endurance to outlast prolonged or difficult workouts and athletic events. You will not be bothered by that depleted, low-energy feeling so common to many athletes who have not found the right pre-workout formula to sustain them during sports training and performance.

In fact, with regular use of Pro Factor X, you will have more energy before, during and after your daily workouts. This unique formula offers comprehensive benefits from nutrient-enriching ingredients that join together to boost your overall energy, endurance and mental concentration. Your post-sports action recovery time will be shorter, smoother and painless as your entire body is revitalized with the aid of this pure, effective supplement. You will leave the gym or sports event arena with plenty of spare energy and body strength to last throughout the remainder of your daily work routine, studies or other activities. In addition, you will sleep soundly and restfully through the night as your sports supplement continues to heal, rejuvenate and strengthen your entire system, getting you prepared for the following day’s sports training or competition.

Their major goal is to help you attain all your athletic desires and dreams as you develop a powerful, ripped body and become a true champ in your favorite types of sports.


How Pro Factor X Works?

This pre-workout formula has a high content of amino acids, which all contribute to vasodilation of your blood vessels and arteries, initiating an increased flow of healthy oxygen via your bloodstream to nurture and strengthen all the muscles of your body as well as other body tissues. Components of this powerful sports enhancing formula also raise the levels of testosterone, growth hormones, insulin and other natural substances in your system. Working together, these nutritional substances can greatly improve your physique as they help you build new lean muscle mass more rapidly than ever before. They also give you a constant supply of higher energy levels, body power, physical stamina and mental determination to excel and become a champ in your favorite area of athletics.

When taken on a regular daily schedule, this fitness supplement will also keep your metabolic rates at a higher level, making it possible for you to drop any excess fat and acquire a slimmer yet more powerful body with impressive muscle definition and density. With higher metabolic rates, your system will also absorb nutrients faster and more thoroughly, using them to support and assist your body in building more lean muscle mass. The combined ingredients of this unique formula will maintain your increased energy and stamina at high levels during and after your intensive gym workouts and sports training sessions. They will also help keep you alert and focused mentally while supporting positive moods and an overall sense of wellbeing throughout your busy days and evenings.


Ingredients of Pro Factor X

This special sports enhancing formula consists of a group of pure, empowering natural substances with properties that will energize, vitalize and strengthen you physically and mentally for better athletic performance. The safe, effective ingredients of this supplement include the following healthy components:

L-Citrulline. – This non-essential amino acid is converted by your kidneys into L-Arginine, which is also an amino acid. Both these natural substances are high in nitric oxide content and stimulate vasodilation of your veins and arteries, promoting the distribution of higher counts of oxygen throughout your body to power-up all your muscles and vital organs for better sports action and results. L-Citrulline also inhibits the onset of feelings of stress and fatigue during intensive gym training and sports events by aiding in the elimination of ammonia build-up in your body, which results from continuous muscle exertion during workouts. The additional nitric oxide (NO2) levels supplied to your system by this ingredient also enhance the activity of your cardiovascular system, enabling you to exercise more strenuously for longer periods of time, making it easier for you to build more dense, strong muscles rapidly.

L-Arginine. – This nutritional formula ingredient promotes the release of testosterone, growth hormones and other healthy substances in the body, all of which will enhance your bodybuilding and athletic strength, stamina and abilities. This valuable amino acid aids your system in building important proteins. Although your body produces L-Arginine naturally, you will need supplementation of this empowering substance if you are seriously pursuing bodybuilding and sports achievement. With its high content of nitric oxide, this ingredient helps dilate the interior walls of your blood vessels and arteries, enabling the delivery of more oxygen throughout your body to fuel your entire skeletal-muscular network for better body strength, endurance and athletic action. This supplement component will also boost the rates of your metabolism, assisting your body with fat shredding for a sleeker physique with improved muscle definition and flexibility.

L-Norvaline. – This formula component helps stop the production of arginase by your body, which makes it possible for your system to produce a steady supply of NO2 during and following your daily workouts. Your muscle pumps will be more powerful and last significantly longer than before. This ingredient also joins with L-Arginine and L-Citrulline to increase regular protein synthesis in your system, improving body strength and sports action. Although L-Norvaline does not assist your body with building new muscle tissue, it supplies large quantities of oxygen and other rich nutrients like additional amino acids to your bodily tissues, giving you longer pumps during workouts and helping to eliminate pain during after-sports recovery periods.
