GDF-8 (Growth Differentiation Factor 8) also known as Myostatin, this is a natural protein that is produced in the muscles of humans and animals. The nature of myostatin has an opposite impact regarding muscle growth and regulates it. In other words, it is responsible for differentiation of muscle tissues and can block or completely stop muscle growth. This protein of myostatin is encoded in the MSTN gene. On the basis of this protein was created the GDF-8 that has all of its original properties (and peptide and protein myostatin belong to the category of substances TGF-beta). Its effects start gradually after it contacts with blood it binds to the receptor ACVR2B and only then it starts to block the dramatic growth of muscles. The myostatin or GDF-8 protects from overgrowth of muscle mass, as well as from undue or disproportionate growth of muscle mass. If the protein isn’t enough in the quantity, there may be anomalies or mutations and might lead to negative consequences.
