About Ipamorelin

Ipamorelin is a synthetic pentapeptide and a potent, selective growth hormone secretagogue. It mimics the action of ghrelin by binding to the ghrelin receptor in the brain, primarily studied for its ability to stimulate the pituitary gland to release growth hormone without affecting other hormones like cortisol or prolactin.

Mechanism of Action

The mechanism involves Ipamorelin acting as an agonist of the Growth Hormone Secretagogue Receptor (GHSR). By binding to these receptors in the pituitary gland, it triggers a pulse of growth hormone release. Unlike other secretagogues, it does not significantly influence the release of other pituitary hormones, making it a subject of interest for highly selective research.
