Ipamorelin 5mg – Growth Hormone Secretagogue Peptide
Ipamorelin — Peptide Overview
Ipamorelin is a synthetic peptide composed of five amino acid residues, placing it within the pentapeptide classification. Its structure contains both conventional and non-standard amino acid components arranged in a defined sequence.
Also identified by the development code NNC 26-0161, ipamorelin can be distinguished through its peptide sequence, molecular formula and CAS registry number. These identifiers provide a consistent reference when comparing chemical records and compound specifications.
Structure and Composition
The peptide sequence of ipamorelin is Aib-His-D-2-Nal-D-Phe-Lys-NH₂. This notation describes the five residues and the chemical form of the peptide’s terminal group.
Aib refers to aminoisobutyric acid, while D-2-Nal identifies D-2-naphthylalanine. The D designation in D-2-Nal and D-Phe specifies the stereochemical configuration of those residues. The final NH₂ notation indicates that the peptide’s C-terminus is amidated.
These details form part of ipamorelin’s chemical identity. Recording the modified residues and terminal group provides a more precise description than amino acid count alone.

Understanding Compound Specifications
Ipamorelin’s identity depends on its amino acid sequence, the configuration of individual residues and its terminal chemistry. These structural details distinguish it from other synthetic pentapeptides, even where compounds share a similar name or classification.
The molecular formula and molecular weight above describe ipamorelin in its free-base form. Ipamorelin acetate is a salt form and should be identified separately in the accompanying chemical specifications.
Compound identity and batch quality are separate pieces of information. The sequence and chemical identifiers describe the molecule, while batch-specific analytical records document the characteristics measured in an individual sample.
