Molecular Nutrition first introduced Arachidonic Acid (ARASYN™) to the supplement world in 2003. This essential fatty acid has since become known as one of the most reliable and effective bodybuilding supplements. It is also the only ingredient clinically proven to break training plateau in experienced lifters, supporting new gains in muscle size, strength, and power. The ability of this EFA to support such gains lies in its fundamental role within the body. Studies show that arachidonic acid is required for the muscles to initiate protein synthesis. Furthermore, regular training can lower levels of this EFA within the muscles. This makes ARA one of the most important supplements for those looking to support optimal muscle growth and athletic performance. X-FACTOR ADVANCED takes arachidonic acid to the next level, with a formula focused on improving the availability, uptake, and versatility of this incredible anabolic nutrient!*


Published in PLOSONE Journal

The effectiveness of arachidonic acid (ARASYN) has been demonstrated in placebo-controlled trials, published in the Public Library of Science (PLOS ONE). Thirty experienced weight-training subjects (age 20.4 ± 2.1 years) were given six capsules of X-Factor per day (1,500mg ARA) or placebo for eight weeks. By the end of the study, the subjects taking arachidonic acid had noticed significant improvements in Lean Body Mass (2.9%; 3.5 lbs), Upper-Body Strength (8.7%), and Peak Power (12.7%). The subjects taking placebo remained stagnant, without significant progress.

Arachidonic Acid is the only supplement ingredient ever shown to break training plateau in experienced lifters like this!



As a dietary supplement, take 4-6 softgels daily for 8 weeks. Follow supplementation program once every 6-12 months, when stuck in a training plateau.
