X-Factor (Arachidonic Acid) - The Original. Patented and Clinically Proven Anabolic.
Brand: Molecular Nutrition

X-FACTOR is an arachidonic acid (ARASYN) supplement for bodybuilders and athletes. An Omega-6 fatty acid, arachidonic acid (ARA) supports the initiation of muscle protein synthesis following exercise. ARA is richly stored in muscle tissues, and these levels may vary. Further, they can be reduced by regular training. This may impair protein anabolism and contribute to training stagnation (plateau). ARA supplementation is recommended to support increases in muscle size, strength, and power, particularly at times when continued progress is slow or has halted. It is the Ultimate Plateau Breaking supplement... and this isn't just hype. It's been proven!

The effectiveness of X-FACTOR 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 X-FACTOR 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.

X-FACTOR is the only supplement ever shown in independent University Studies to break training plateau in experienced weightlifters!
