Product Overview
Ipamorelin is a synthetic pentapeptide growth hormone secretagogue investigated in controlled laboratory and clinical research for its interaction with the growth hormone secretagogue receptor, also known as the ghrelin receptor (GHSR/GHS-R1a).
Ipamorelin has the sequence Aib-His-D-2-Nal-D-Phe-Lys-NH₂ and was developed as a selective growth hormone secretagogue. Experimental studies have examined its effects on GH release, pituitary signaling, ghrelin-receptor biology, pharmacokinetics, and gastrointestinal motility.
The original pharmacology literature describes Ipamorelin as a selective growth hormone secretagogue with the sequence Aib-His-D-2-Nal-D-Phe-Lys-NH₂.
The National Cancer Institute describes it as a ghrelin mimetic that binds the ghrelin/growth hormone secretagogue receptor and stimulates GH release.
Ipamorelin has also been evaluated in human pharmacokinetic/pharmacodynamic research, where investigators characterized its disposition and the time course of GH stimulation.
These findings describe research observations and do not establish approved therapeutic use of the research product supplied here.
Ipamorelin is relevant to controlled experimental investigations involving ghrelin receptor biology, GH secretion pathways, pituitary signaling, endocrine pharmacology, and peptide-receptor interactions.
Because it acts through GHSR rather than GHRHR, Ipamorelin is mechanistically distinct from GHRH analogs such as CJC-1295. This makes it useful in comparative research examining different receptor pathways involved in GH secretion.

Growth Hormone Secretagogue Receptor (GHSR / GHS-R1a), also known as the ghrelin receptor The NCI describes Ipamorelin as a ghrelin mimetic that binds the ghrelin/GH-secretagogue receptor.
Clinical Research Ipamorelin has been evaluated in controlled human pharmacokinetic/pharmacodynamic studies in addition to substantial preclinical research. This classification refers to the existence of human research, not FDA approval or established therapeutic efficacy.
Ipamorelin is a synthetic pentapeptide growth hormone secretagogue composed of the sequence Aib-His-D-2-Nal-D-Phe-Lys-NH₂. Its structure incorporates non-natural residues, including α-aminoisobutyric acid (Aib), D-2-naphthylalanine, and D-phenylalanine, and it terminates in a lysinamide. The peptide was developed for selective interaction with growth hormone secretagogue receptor signaling.
Aib-His-D-2-Nal-D-Phe-Lys-NH₂ The sequence is reported in the original pharmacology literature describing Ipamorelin.
