Research overview
Ipamorelin is a synthetic pentapeptide and selective growth hormone secretagogue (GHS) that mimics the action of ghrelin.
It stimulates the pituitary gland to release growth hormone (GH) in a pulsatile and natural manner with high specificity. Unlike some other secretagogues, Ipamorelin is researched for producing minimal impact on cortisol, prolactin, or appetite while still promoting GH levels.
