How it works.
Sermorelin is a synthetic peptide corresponding to the first 29 residues of human growth hormone-releasing hormone (GHRH 1–29), the active fragment of the full 44-residue native peptide. It engages the GHRH receptor on anterior pituitary somatotrophs, stimulating endogenous GH release in a pulsatile, physiological pattern. Half-life is short — approximately 10–20 minutes — favoring evening administration in protocols designed to align with circadian GH secretion.
