Ipamorelin (also known as Growth hormone secretagogue) is a selective growth-hormone secretagogue studied for its clean GH-release profile. This page covers what the published research does — and does not — establish about it in relation to muscle growth and recovery.
Ipamorelin is researched for Growth hormone release, Recovery — which is why it appears in discussions of muscle growth and recovery.
Research status: Preclinical and early human pharmacology research.
How Ipamorelin is thought to work
Ipamorelin is a selective growth-hormone secretagogue that mimics ghrelin at its receptor to trigger growth-hormone release. It is valued in research for a relatively "clean" profile, with less effect on appetite, cortisol, and prolactin than some older secretagogues.
What it does not establish

Frequently asked questions
Preclinical and early human pharmacology research. Research relevant to this area covers growth hormone release, recovery. That is a description of where the research points, not evidence that it will work for you — and Selpho does not provide dosing or medical advice.
Preclinical and early human pharmacology research.
Endocrine-active. Not an approved medication for these uses. Always speak to a licensed healthcare professional before considering any peptide.
Stimulating growth-hormone release, with interest in recovery and body composition. It is often paired with a GHRH analog like CJC-1295.
Compared with earlier secretagogues, it tends to raise growth hormone with fewer off-target effects on cortisol, prolactin, and hunger in studies.
