Methenolone is an anabolic steroid.When entering the cell nucleus it stimulates the genetic apparatus of the cell, which leads to increased synthesis of DNA, RNA and structural proteins, activates tissue respiration chain enzymes and enhancing tissue respiration, oxidative phosphorylation, ATP synthesis and intracellular macroregion aggregation. It stimulates anabolic processes and inhibits the catabolic one caused by glucocorticoids. Methenolone administration leads to increased muscle mass, reduces fat deposits, improves trophic tissues, promotes calcium deposition in bones, retains sodium and water in the body. The hematopoietic action is determined by the increase of erythropoietin synthesis. Androgenic action may contribute to the development of male secondary sexual characteristics type.
