Somatostatin-14 (SST-14)

Native somatostatin, a cyclic tetradecapeptide. Widely distributed in central and peripheral tissues, it inhibits the secretion of multiple hormones (GH, TSH, insulin, glucagon, gastrin, etc.). It has a very short half-life (2–3 minutes). Research grade, for studies of somatostatin physiological function, receptor subtypes, and endocrine regulation.
