Growth Hormone-Releasing Hormone · Somatoliberin

GHRH is the endogenous 44-amino-acid hypothalamic peptide that drives the pulsatile secretion of growth hormone from the anterior pituitary. Native GHRH acts through GHRHR, stimulating GH gene transcription and secretion. It has a very short half-life in vivo, making it impractical as a therapeutic — which drove the development of modified analogs like sermorelin, CJC-1295, and tesamorelin. Research into GHRH receptor signaling underpins the entire GH secretagogue drug class.

Egrifta · TH9507

Tesamorelin is a stabilized synthetic GHRH analog FDA-approved for reduction of excess abdominal fat in HIV-infected adults with lipodystrophy. It stimulates pulsatile GH secretion while preserving natural feedback regulation. Research demonstrates significant visceral adipose tissue reduction, improved lipid profiles, and cognitive benefits, making it a key study compound for metabolic dysfunction.
