Key Ingredients
A five-amino acid peptide that selectively stimulates growth hormone release via the GHS-R1a receptor. Research highlights its selectivity profile with minimal effects on ACTH, cortisol, and prolactin.
Ipamorelin is a selective growth hormone secretagogue pentapeptide (Aib-His-D-2-Nal-D-Phe-Lys-NH2). It stimulates growth hormone release by acting on the ghrelin/growth hormone secretagogue receptor (GHS-R) without significantly affecting cortisol, prolactin, or ACTH levels.
Research Background
Ipamorelin has been studied for its highly selective growth hormone-releasing properties. Unlike other GH secretagogues, ipamorelin demonstrates minimal effects on other pituitary hormones, making it a preferred research compound for studying isolated GH axis modulation. This product is for research purposes only.

Growth Hormone Secretagogue
Selective GHS receptor agonist for growth hormone research
Ipamorelin is a synthetic pentapeptide growth hormone secretagogue (GHS) that selectively activates the ghrelin/GHS receptor. Unlike other GHS compounds, Ipamorelin does not significantly affect cortisol or prolactin levels in research models.
