What Is Ipamorelin? A Guide to Growth Hormone Research
Understanding This Selective Growth Hormone Secretagogue
Short answer: Ipamorelin is a synthetic five-amino-acid peptide classed as a selective growth hormone secretagogue. Researchers study how it binds the GHS-R receptor.
Last updated: 20 October 2026
Introduction
Among growth hormone-related peptides, Ipamorelin has attracted significant attention from researchers. Classified as a growth hormone secretagogue (GHS), Ipamorelin is studied for its potential to stimulate the release of growth hormone through a specific receptor-mediated mechanism.
This article explores Ipamorelin’s structure, potential mechanisms, and its role in contemporary peptide research.
What Is Ipamorelin?
Ipamorelin is a pentapeptide — a chain of just 5 amino acids — that is considered to be a selective growth hormone secretagogue. It is designed to mimic the hormone ghrelin and potentially bind to the growth hormone secretagogue receptor (GHS-R).
Key properties:
- 5 amino acids (Aib-His-D-2-Nal-D-Phe-Lys-NH2)
- Molecular weight: ~711.9 g/mol
- Considered highly selective for GH release
- Studied for minimal impact on other hormones
How Ipamorelin Works
Ipamorelin is posited to bind to the Growth Hormone Secretagogue Receptor (GHS-R), which may trigger the release of stored growth hormone from the pituitary gland. What makes Ipamorelin of particular interest to researchers is its potential selectivity — it is considered to stimulate GH release with potentially less impact on cortisol, prolactin, and other hormones compared to other GHS compounds.
