What is Epistane?

Originally formulated in Japan by Searle Laboratories, a methyl free version of the compound was developed to fight breast cancer and gynocomastia. Epistane is an estrogen blocking prohormone with the nomenclature 2a 3a-epithio-17a-methyl-5a-androstan-17b-ol . It creates muscle mass by binding to androgen receptors in muscle ll.lstem cells and skeletal muscle cells, changing protein synthesis and muscle cell function. Muscle stem cells will eventually change, fusing with active skeletal muscles and increasing the repair and growth potential of the muscle. Also, androgens cause the production of fat cells to decrease in stem cells, causing a reduction in new fat cells. Stem cells are converted to muscle cells and less fat is produced by existing stem cells. This provides an advantage of those looking to build lean muscle by adding to the productivity of nutritional diet and exercise. 2a 3a-epithio-17a-methyl-5a-androstan-17b-ol is a widely popular alternative to commonly used anabolic steroids.
