When taking Mesterolone, given are some of increases in muscle, even if minimal, more or less it's about muscle hardness and density. It is known that androgen receptors are found in the muscle and in fat cells and therefore, the use of Mesterolone together with testosterone promotes muscle growth but also a loss of fat.
It is only slightly hepatotoxic to liver and kidney, because it is not a C17-alpha-alkylated substance. Mesterolone does not affect the formation of testosterone. This substance stimulates the body to produce testosterone, used only as a substance that is used to compensate the lack of the natural male androgen.
