It acts by binding to GHRH receptors on pituitary somatotroph cells, thereby modulating the endogenous secretion of growth hormone through physiological regulatory pathways. This mechanism supports the maintenance of normal growth hormone dynamics within the hypothalamic-pituitary axis. Pulsatile GH SecretionSermorelin is associated with stimulating the synthesis and pulsatile secretion of growth hormone from pituitary somatotrophs. Hypothalamic-Pituitary FeedbackSermorelin preserves hypothalamic-pituitary feedback regulation, with growth hormone release modulated by somatostatin inhibition to maintain physiological levels. GH Secretory Pattern RestorationSermorelin has been evaluated for its role in supporting restoration of normal growth hormone secretory patterns, including nocturnal surges linked to sleep architecture. IGF-1 Production SupportSermorelin may support downstream production of insulin-like growth factor 1 (IGF-1) within physiological ranges. Pituitary Trophic EffectsSermorelin demonstrates trophic effects on the pituitary gland in preclinical models, potentially contributing to sustained pituitary responsiveness over time.
