Ipamorelin is a synthetic peptide classified as a growth hormone secretagogue.
What it does
It stimulates the pituitary gland to release growth hormone (GH) by mimicking the action of ghrelin (the “hunger hormone”) and binding to the ghrelin (GHS-R1a) receptor.
Key characteristics
Selectively increases growth hormone with minimal effect on cortisol or prolactin (compared to some older GH secretagogues).
Has a relatively short half-life.
