Research
Ipamorelin is a synthetic pentapeptide (Aib-His-D-2-Nal-D-Phe-Lys-NH2) supplied here as a 5 mg lyophilized reference material for in-vitro and preclinical laboratory work. It carries the molecular formula C38H49N9O5 and CAS number 170851-70-4. Structurally it is a short, sequence-defined amidated peptide built partly from non-natural residues — the alpha-aminoisobutyric acid (Aib) cap and the D-configured 2-naphthylalanine and phenylalanine — which distinguish it from a simple linear chain of proteinogenic amino acids. In the research literature Ipamorelin is classified as a growth-hormone secretagogue and is frequently described as one of the more receptor-selective members of that peptide family, which is why it recurs as a comparator compound in mechanistic studies.
Interest in Ipamorelin as a research substance centers on its reported selectivity at the growth-hormone secretagogue receptor (GHSR-1a, the ghrelin receptor) in cell-based systems. It is used on the bench as a tool compound for probing this receptor and associated signaling readouts. The compound has no established consumer application; the surrounding body of work is preliminary and ongoing, and results from receptor assays and rodent-model experiments should not be extrapolated to human or animal outcomes.
Published investigations involving Ipamorelin are predominantly in-vitro and rodent-model in nature. Reported experimental lines of inquiry include GHSR-1a receptor-binding and functional-activation assays, comparisons of secretagogue selectivity against related peptides, and measurement of downstream signaling endpoints in cultured pituitary-derived cells. Researchers have also used the peptide in isolated-tissue and rodent-model preparations to characterize dose-response behavior and receptor pharmacology under controlled laboratory conditions.
These references describe experimental laboratory work only. They are not medical claims, are not evidence of safety or efficacy in humans or animals, and should not be interpreted as guidance for any use outside a controlled research environment.
Each research lot of Ipamorelin is supplied as a lyophilized white powder and characterized before release. Identity and purity are established using orthogonal analytical methods so that the material described on the Certificate of Analysis (COA) matches the sequence and mass expected for this amidated pentapeptide. This dual-method approach separates purity — how much of the sample is the target peptide — from identity, the confirmation that the target is the correct molecule.
The COA accompanying each product is the definitive analytical record for that specific lot. Because purity and mass can vary slightly between synthesis batches, researchers should reference the COA tied to the lot number received rather than generic specifications when documenting experimental inputs. Retaining the COA alongside experimental records supports reproducibility and traceability across studies.
As a lyophilized peptide, Ipamorelin is hygroscopic and sensitive to repeated temperature cycling. Standard laboratory practice is to allow the sealed vial to equilibrate to room temperature before opening to minimize condensation, then reconstitute with an appropriate research-grade solvent under aseptic technique. Aliquoting reconstituted stock into single-use portions limits the freeze-thaw cycles that can degrade peptide integrity. Detailed temperature and stability windows for lyophilized, reconstituted, and working solutions appear in the storage table on this page. This handling guidance applies to laboratory storage only and does not imply any human or animal application.
It is a synthetic pentapeptide (Aib-His-D-2-Nal-D-Phe-Lys-NH2) with the formula C38H49N9O5 and CAS 170851-70-4, supplied as a 5 mg lyophilized reference material. In the research literature it is classified as a growth-hormone secretagogue and is often cited for its reported selectivity at the ghrelin/GHSR-1a receptor, which makes it a common tool compound in receptor-pharmacology studies.
It ships as a lyophilized (freeze-dried) white powder in a sealed vial containing 5 mg of peptide. Lyophilization improves shelf stability for a research peptide and lets the researcher reconstitute with a solvent of their choice under aseptic conditions when preparing in-vitro experiments.
Purity is measured by reversed-phase HPLC and reported as a percentage of total peak area (≥99% for this product), while identity is confirmed by mass spectrometry — ESI-MS or MALDI-TOF — against the theoretical mass for C38H49N9O5. The lot-specific COA documents both values plus appearance and net peptide content, and is the authoritative analytical record for the exact material you receive.
Published work is predominantly in-vitro and rodent-model, spanning GHSR-1a receptor-binding and functional-activation assays, comparative selectivity studies against other secretagogue peptides, and downstream signaling readouts in cultured pituitary-derived cells. This research is preliminary and ongoing, describes laboratory systems only, and does not establish any human or animal outcome.
Allow the sealed vial to reach room temperature before opening to prevent condensation on the hygroscopic powder, reconstitute using aseptic technique with a research-grade solvent, and aliquot the stock to avoid repeated freeze-thaw cycles. Follow the temperature and time windows in the storage table on this page for lyophilized, reconstituted, and working solutions. This is laboratory handling guidance only.
