Arachidonic Acid!

Faster And More Profound Increases In Muscle Size And Strength!*



Muscle Size, Strength, and Power


supplement for bodybuilders and athletes. An Omega-6 fatty acid, arachidonic acid plays an important role in various aspects of cognitive, immune, and metabolic health.

As a sports supplement, ARA is used to support increases in muscle size, strength, and power, as well as muscle preservation during fat loss. The ability of ARA to support these goals lies in its fundamental role within the body.

ARA is essential for the initiation of muscle protein synthesis following exercise. Furthermore, regular exercise may lower ARA levels in the muscles. This makes X-FACTOR one of the most important supplements for supporting optimal muscle growth and athletic performance.


The effectiveness of X-FACTOR™ has been demonstrated in placebo-controlled trials at the University of Tampa. Thirty weight-training male subjects (age 20.4 ± 2.1 years) with a minimum of 1 year of resistance training experience were given six capsules of X-Factor per day (1,500mg ARA) or placebo for eight weeks. Subjects taking X-Factor noticed significantly greater improvements on all muscle size and performance variables tested, including an 88% greater increase in muscle size (thickness) measures. They also added an average of 21 lbs. to their bench press, 89 lbs. on leg press, gained about 4 lbs. of lean body mass (LBM), and noticed a 5.5 times greater increase in muscle power compared to placebo!

Baylor University also conducted a clinical investigation on X-Factor™ supplementation. Thirty-one weight-training male subjects (22.1 ± 5.0 years) were given four capsules of X-Factor (1,000mg ARA) per day or placebo for 50 days. Subjects taking X-Factor noticed a significant increase in peak muscle power (AA: 1.2 ± 0.5; P: -0.2 ± 0.2 W), along with statistically strong improvements in bench press 1-rep max (ARA: 11.0 ± 6.2; P: 8.0 ± 8.0 kg), average muscle power (ARA: 37.9 ± 10.0; P: 17.0 ± 24.0 W), and muscle endurance (ARA: 1292 ± 1206; P:510 ± 1249 J). X-Factor supplementation was also associated with a reduction in inflammatory marker IL-6.

What People are Saying

Bodyspace member: TheMan_005

“I'm on week 5 with this and I've gained amazing strength on every lift. But have gained almost 2 inches on my chest, 1 inch to the shoulders, 1/2 inch to my neck, 1/4 inch to the arm, and about a 1/4 inch to the legs. Maintained a 32-1/2inch waist and lost 1/2 inch off my hips. Amazing stuff.”

Bodyspace member: jorgemontenegro

“Hands down, one of the best, most effective supplements that I have ever used. Huge strength and muscle gains after 50 days. Recomping effect. Totally worth the money. Best non-hormonal anabolic product on the market.”

Bodyspace member: MultiVitamin

“I finished weighing in @ 162 (+11 lbs), arms are better filled, and am noticeably stronger, overall. Final Words — Great product, and great results, …IMO, XF is the best natural supplement.”

Bodyspace member: Wafaison

“This is the only supplement that I have ever truly thought did exactly as it promised. I felt insane pumps, good strength gains, and very good weight and size gains. …My deadlift soared. In 8 weeks I went from barely, barely eeking up 320, to getting 350 all the way to lockout.
