Pharmacological properties

Anabolic steroid methenolone is. Getting Inside the cell nucleus, stimulates the genetic apparatus of the cell, leading to increased synthesis of DNA, RNA and structural proteins, active enzymes chain breathing tissue and enhancing breathing tissue oxidative phosphorylation, ATP synthesis and assembly of intracellular macroergic . Stimulates anabolic processes and inhibits their catabolic those caused by glucocorticoids. Leads to increased muscle mass, reducing fat deposits, improves trophic tissues, promote calcium deposition in bones, retain sodium and water in the body.
