Growth Hormone-Releasing Hormone (GHRH)

Somatocrinin, Somatoliberin, Growth Hormone-Releasing Factor (GRF), GHRF

Hypothalamic peptide controlling growth hormone synthesis and release, mainly used diagnostically (GHRH-arginine test) for GH deficiency. Approved analogs like tesamorelin serve specific therapies, while recent research (2020–2025) focuses on GHRH receptor involvement in cancer growth, making GHRH antagonists an oncology target.

Mechanism

Binds GHRH receptors on pituitary somatotrophs, raising cAMP/PKA signaling to open calcium channels and stimulate GH synthesis and secretion; works opposite somatostatin to create pulsatile GH release, modulated by IGF-1 feedback.

Safety file

Fluid retention, joint pain, and muscle aches are common; risks include hyperglycemia, insulin resistance, and theoretical long-term diabetes or malignancy concerns.
