What Is Ipamorelin?
A selective ghrelin-receptor agonist studied for clean growth-hormone secretagogue activity.
01Definition
Ipamorelin is a endocrine research compound. A selective ghrelin-receptor agonist studied for clean growth-hormone secretagogue activity. It is also known as NNC 26-0161.
Sequence · Aib-His-D-2-Nal-D-Phe-Lys-NH2
02Research Mechanism
Ipamorelin is a synthetic pentapeptide and selective agonist of the ghrelin receptor (GHS-R1a). In research models it stimulates growth-hormone release from the pituitary with notable selectivity — published work emphasizes minimal effect on prolactin, cortisol, and ACTH compared with earlier secretagogues.
