X-Factor is the world's first patented hypertrophic catalyst. By enhancing the storage of arachidonic acid in exercised muscles, X-Factor drastically amplifies the body's sensitivity and responsiveness to resistance training. This means faster and more profound increases in muscle size, strength, even the rate of lipolysis (fat loss).

During intense muscular exercise the cells release arachidonic acid causing the muscle cells to be bombarded with prostaglandins, the body's main tissue repair messengers. This causes a shift in post-exercise physiology promoting muscle growth, strength, endurance, pumps and fat loss. The more arachidonic acid released by the muscle cells the greater the anabolic response.

March 31, 2007 Reviewer: A customer in California It did not work for me. I followed every instruction recommended. I completed my 50 days cycle of X – Factor and I have not seen any improvement as claimed in your website. On the contrary I am losing my hair and almost close to being bald in some areas.
