ACE-31 is a myostatin inhibitor (GDF-8 – a substance which can decelerate and restrain muscle growth). By blocking myostatin, ACE-31 supports faster, greater and more efficient muscle gain.
Moystatin (GDF-8 = Growth differentiation factor 8) is a protein that in humans is encoded by the MSTN gene. Moystatin (GDF-8) belongs to the GDF proteins family that inhibits muscle growth. The moystatin protein is produced primarily in the skeletal muscle cells, circulates in the blood and acts on muscle tissues – it slows down the stem cells differentiation (and inhibits new muscle mass production).
