Ipamorelin is a synthetic peptide that stimulates the release of growth hormone (GH) by selectively binding to the ghrelin receptor (GHS-R1a). Known for its mild and targeted action, it boosts GH and IGF-1 levels with minimal side effects, such as reduced cortisol and prolactin release compared to other GH secretagogues.

It is commonly studied for its potential benefits in muscle growth, fat loss, anti-aging, and recovery. Ipamorelin is widely used in research and hormone optimization therapies, though it is not FDA-approved for general medical use.
