Sermorelin is a synthetic 29-amino-acid peptide corresponding to the N-terminal fragment (1–29) of growth-hormone-releasing hormone (GHRH) — the shortest sequence that retains full GHRH biological activity. In research models it has been studied for its effects on pulsatile GH secretion, IGF-1 levels, and GHRH-receptor signaling.

Sermorelin is used in GH/IGF-1 axis research, pituitary somatotroph function models, and preclinical studies of GHRH-receptor pharmacology.
