Ipamorelin is a synthetic research peptide that has gained attention in laboratory and preclinical research due to its selective interaction with specific receptor signaling pathways. It is commonly discussed in experimental research models focused on peptide–receptor binding and signaling specificity.
This page provides an educational overview of Ipamorelin for laboratory research purposes only. NexPept supplies Ipamorelin strictly for non-clinical research applications, with an emphasis on purity, documentation, and consistency. New to the topic?

What Is Ipamorelin?
Ipamorelin is a synthetic pentapeptide, a chain of 5 amino acids, developed for research into receptor-based signaling mechanisms. In laboratory settings, it has been studied for its selective interaction profile and structural characteristics compared to other research peptides in the same class.
Because of its specificity, Ipamorelin has become a point of interest in experimental research environments examining controlled peptide–receptor interactions.
Ipamorelin Chemical Profile: Sequence, CAS Number & Molecular Weight
The core identifiers for Ipamorelin are listed below. Researchers use these values to confirm that the material they receive matches the compound they ordered.
| Compound | Ipamorelin |
| CAS number | 170851-70-4 |
| Classification | Synthetic pentapeptide, selective growth hormone secretagogue (GHS) research compound |
| Length | 5 amino acid residues |
| Sequence | Aib-His-D-2-Nal-D-Phe-Lys-NH2 |
| Molecular formula | C38H49N9O5 |
| Molecular weight | ~711.85 Da |
| Physical form | Lyophilized powder, white to off-white solid |
| Analytical methods | HPLC + mass spectrometry (MS) |
Aib = alpha-aminoisobutyric acid; D-2-Nal = D-2-naphthylalanine; D-Phe = D-phenylalanine. These are non-standard residues, which is part of why Ipamorelin is described separately from a simple string of the 20 common amino acids.
Why Researchers Study Ipamorelin
In laboratory and preclinical research settings, Ipamorelin has been examined in in vitro research involving:
All findings related to Ipamorelin remain within research and experimental contexts, and interpretations should be limited to laboratory data. To explore the published literature, you can search PubMed for Ipamorelin research papers.
Purity & Documentation in Research Peptides
High peptide purity is critical for reproducible research outcomes. Variations in synthesis quality or incomplete documentation can introduce inconsistencies into experimental data. High-quality research peptides should include:
When you review any Ipamorelin COA, check that the lot number matches your vial, that purity is reported from HPLC analysis, and that the identity is confirmed by mass spectrometry with a mass consistent with the expected ~711.85 Da. For a worked example of reading a COA, see our BPC-157 research peptide overview.
Storage & Handling (Research Use)
Proper storage and handling help preserve peptide stability during laboratory research. General laboratory considerations may include:
Always follow your laboratory's established procedures when working with peptide compounds. No preparation, reconstitution, or administration instructions are provided.

What is the CAS number for Ipamorelin?
The CAS registry number for Ipamorelin is 170851-70-4.
What is the sequence and molecular weight of Ipamorelin?
Ipamorelin has the sequence Aib-His-D-2-Nal-D-Phe-Lys-NH2, the molecular formula C38H49N9O5, and a molecular weight of approximately 711.85 Da.
Is Ipamorelin approved by Health Canada?
No. Ipamorelin has not been authorized by Health Canada for human or veterinary use. NexPept supplies it for laboratory research use only.
What is the difference between Ipamorelin and CJC-1295?
They are different compounds studied together in secretagogue research. Ipamorelin is a 5-amino-acid selective growth hormone secretagogue, while CJC-1295 is a longer synthetic analog of growth hormone-releasing hormone (GHRH). NexPept also supplies a CJC-1295 (no DAC) + Ipamorelin blend for research combining both.
How should Ipamorelin be stored for research?
Store sealed lyophilized material under controlled laboratory conditions, protected from light and moisture, and follow your institution's approved handling protocols. Storage parameters should be set by qualified research personnel.
