About this product
GHK-Cu — Copper Peptide Overview
GHK-Cu is a copper–peptide complex formed from the tripeptide glycyl-L-histidyl-L-lysine and copper(II). Commonly known as copper tripeptide-1, it contains three amino acid residues arranged in the sequence glycine–histidine–lysine.
The abbreviation GHK represents the single-letter codes for these amino acids, while Cu is the chemical symbol for copper. The complete name identifies the copper-bound peptide and distinguishes it from GHK without copper.
Structure and Composition
The peptide component of GHK-Cu has the sequence Gly-His-Lys, also written as GHK. Its three amino acid residues are connected by peptide bonds, forming a tripeptide that coordinates with a copper(II) ion.
Coordination describes the chemical association between the peptide and the metal ion. The copper forms part of the complex’s chemical identity, contributing to its molecular composition and molecular weight.
GHK and GHK-Cu therefore have different chemical specifications. Identifying the copper complex explicitly helps avoid confusion when comparing peptide names, reference records and analytical documentation.

Understanding Compound Specifications
“Copper peptide” is a broad description that can refer to different peptide complexes containing copper. GHK-Cu identifies the particular complex associated with the Gly-His-Lys sequence.
Chemical references may describe different salt forms or representations of copper–peptide complexes. The formula and molecular weight above refer to the specified GHK-Cu complex; an acetate salt has additional components and separate specifications.
Compound identity and batch quality are separate pieces of information. The peptide sequence, copper content and chemical identifiers describe the material’s composition, while batch-specific analytical records document the characteristics measured in an individual sample.
