Research Status

Overview

Ipamorelin is a selective growth hormone secretagogue and ghrelin mimetic. It is widely regarded as one of the cleanest GH-releasing peptides available due to its high selectivity — it stimulates GH release without significantly increasing cortisol or prolactin.

Mechanism of Action

Ipamorelin mimics ghrelin and binds to the GHS-R1a receptor in the pituitary and hypothalamus, selectively stimulating GH release. Its selectivity means it does not trigger the cortisol or prolactin spikes seen with other GH secretagogues.
