Somatostatin-14 is a natural cyclic peptide hormone derived from the preprohormone, full-length somatostatin.¹ Somatostatin-28, which includes somatostatin-14 plus another fourteen amino acids, is also formed from the parent protein. Both forms have similar biological activities but differ in their potency. Somatostatin-14 inhibits the release of growth hormone, prolactin, thyrotropin, glucagon, and insulin, as well as other signaling molecules.^1,2,3
