The Plateau breaker! 

Not feeling the burn or DOMS anymore? Not gaining muscle mass like you use too? 

X- Factor's Arachidonic Acid (ARASYN™): The only ingredient clinically proven to break training plateau in experienced lifters, supporting new gains in muscle size, strength, and power.

Supports Increased Muscle Mass and Strength. X-Factor Advanced-Taking Arachidonic Acid to the Next Level! X-Factor Advanced has been enhanced with several key ingredients to help amplify arachidonic acid's potency. By making each milligram more effective, a greater level of muscle growth can be supported in a shorter period of time. This task was accomplished by increasing the availability, uptake and active conversion of acachidonic acid. Bioavailability: The stability and bioavailability of arachidonic acid are increased in X-Factor Advanced. This enables more of this important nutrition to survive the first pass through the digestive system and reach the muscle tissue intact. Cellular Uptake: The cellular uptake and membrane stability of arachidonic acid have been enhanced. With more of this fatty acid pulled into and stored in the outer layer of the muscle cells, more will be available to stimulate key anabolic pathways after each training session. Enzyme Support: After intense training, arachidonic acid must be metabolized to active biochemicals before it can support muscle anabolism. By reducing the metabolism of arachidonic acid by unwanted enzyme pathways, more of this nutrition is available for conversion to series 2 prostaglandins, thereby increasing the anabolic response. X-Factor Advanced combines clinically the proven power of arachidonic acid with new deliver y and utilization technology that only the science of William Llewellyn and Molecular Nutrition can bring you. X-Factor Advanced is simply the most powerful muscle building supplement available anywhere! X-Factor Advanced Proprietary Anabolic Formula: Arasyn 40% Arachidonic Acid Oil in a Proprietary Fatty Acid/Oil Blend, Ultra Purified Omega-3 Concentrated Fish Oil, Boswellia Serrata Resin 18%.

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!
