GDF-8 Peptide

Growth and Differentiation Factor-8 (GDF-8) is another name for myostatin, a muscle growth inhibitor. Muscles of all ages and stages of human development express myostatin. As a myokine, myostatin falls within this category. Muscle contractions create and release cytokines and other peptides known as myokines. Myostatin is expressed in skeletal muscle, heart muscle, and adipose tissue.
