Growth Hormone-Releasing Hormone

Meaning

Growth Hormone-Releasing Hormone (GHRH) is a hypothalamic peptide hormone that serves as the primary physiological stimulator of growth hormone (GH) secretion from the anterior pituitary gland. This neurohormone is released in a pulsatile fashion, directly dictating the rhythmic release pattern of GH into the systemic circulation. GHRH is a critical upstream regulator within the Growth Hormone Axis, essential for the body’s anabolic processes and metabolic regulation. Its proper signaling is fundamental for normal growth, development, and maintenance of lean mass.
