Structure of the compound on this page.
Ipamorelin from Cleared Peptides is a research-grade compound supplied for laboratory and analytical investigation. Every lot is third-party tested, and the batch Certificate of Analysis is published before sale. Specifications, CAS number and molecular formula are listed below.
Research use only. Ipamorelin is supplied for laboratory research. It is not a drug, food, cosmetic, or dietary supplement. It is not FDA-approved. It is not for human or veterinary administration. This page does not give a dose or a method of administration. A study cited on this page describes that study’s own test article. It does not make this lot an approved medicine. To check a fact, open the PubMed or DOI link, confirm the authors and year, and match the paper’s compound name, CAS number, or sequence to the specification table. The full method is on the research desk page. Identity and purity for a lot are only what that lot’s certificate of analysis reports. An HPLC percentage is not a sterility result and not an endotoxin result unless the certificate prints those tests.

Ipamorelin is a synthetic pentapeptide (Aib-His-D-2-Nal-D-Phe-Lys-NH2) characterized as a selective agonist of the growth-hormone secretagogue receptor (GHSR-1a, the ghrelin receptor).
It is a reference ligand in GHSR receptor-binding and signaling studies, and is frequently compared with GHRH analogs such as tesamorelin.
This summary describes published laboratory research only and makes no claim about effects in humans or animals.
Each lot of Ipamorelin is analyzed by an independent laboratory, with identity and purity (or composition, for multi-component preparations) reported on a lot-specific Certificate of Analysis. View current results on our COA page.

Research use only. This ipamorelin material is for laboratory research, code NNC 26-0161, CAS 170851-70-4. It is not for human or veterinary administration. The cell-assay numbers below are the paper’s numbers. They are not a dose.
Raun, Hansen, Johansen, and colleagues (European Journal of Endocrinology, 1998) describe ipamorelin as the pentapeptide Aib-His-D-2-Nal-D-Phe-Lys-NH2, selected from a series that removed the central Ala-Trp dipeptide of GHRP-1. In primary rat pituitary cells they report growth-hormone release with EC50 1.3 ± 0.4 nmol/L and Emax 85 ± 5 percent, close to GHRP-6 in that assay (2.2 ± 0.3 nmol/L, Emax 100 percent). Antagonist experiments in the paper place the activity on a GHRP-like receptor, which is the ghrelin-receptor pathway, not the GHRH receptor. The title’s word “selective” is their claim from a hormone panel in the models they ran. A reader should look at that panel in the paper rather than treat the adjective as a new measurement. They also report growth-hormone release in pentobarbital-anaesthetized rats. That is an animal pharmacology result. PubMed 9849822, DOI 10.1530/eje.0.1390552.
The catalog table matches the sequence, formula C38H49N9O5, mass about 711.9 g/mol. Aib and D-2-naphthylalanine are not proteinogenic. An identity method that assumes twenty standard amino acids will mis-assign the mass. Stereochemistry at the D residues is part of the specification.
Tesamorelin is a 44-residue analogue of growth hormone-releasing hormone. Falutz’s trial studied that analogue as a drug. Ipamorelin is five residues and, in Raun’s antagonist experiments, uses the GHRP receptor. Both conversations are about growth hormone. The receptors are different, the masses are different (about 711.9 versus about 5135.9), and the papers are not interchangeable. There is also no basis on this site for mixing ipamorelin with MOTS-c or tesamorelin and citing either paper for the mixture.
