TestoFEN X is the first product ever designed which can stimulate the body's own production of Androgens to increase muscularity, strength and increased sex drive! By stimulating the Adrenal cortex TestoFEN X causes the release of the body's own muscle building factory, Androgens! The most common of these androgens produced you may have already heard of, Androstenedione! Yes, TestoFEN X causes your body to produce its own Androstenedione! TestoFEN X uses its Anabolic 19-carbon "testosterone-like" structure to produce increases in lean muscle, strength and sex drive by a dual mechanism of action.

First TestoFEN X acts through the Adrenal Cortex by stimulating the secretion of Corticotropin Releasing Hormone (CRH) from the Hypothalamus in the brain. The CRH then causes the production of Adrenocorticotropic Hormone [ ACTH ] from the Anterior Pituitary Gland. ACTH then acts on the cells of the Adrenal Cortex stimulating them to produce Androgens. Androgens are precursors to Testosterone with Testosterone like activity, the common one being Androstenedione. Testosterone and Androstenedione are interconvertible in our body, especially in the peripheral sites of action like muscles where Androstenedione converts more into Testosterone than the reverse.

In addition to stimulating the body's production of Androstenedione, Testofen also seems to have Testosterone-like properties all on its own. It seems to bind to the Testosterone receptor sites in the body and seems to stimulate anabolic and androgenic activity similar to Testosterone. This has been verified by new soon to be published studies. Don't waste time with old fashion Tribulus / Longjack products when you can begin growing the muscle you want now!
