• Appearance Clarification: The visible colour of a formulated lyophilised material is influenced by peptide concentration, copper concentration, complexation status, mannitol content, moisture and batch presentation. Colour alone does not establish chemical identity or purity.
• Complexation Status: The applicable Certificate of Analysis should state whether the supplied material contains a preformed GHK-Cu complex or a formulation of GHK with a copper(II) sulphate source
• Copper Stoichiometry: The molar peptide-to-copper ratio and total copper content should be confirmed using appropriate batch-specific analytical data
• Purity Interpretation: High-performance liquid chromatography purity of the GHK peptide component does not, by itself, establish copper content, copper complexation, mannitol content or total formulated material content
• Analytical Interpretation: Peptide identity, chromatographic purity, copper content, copper oxidation state, complexation status, water content, residual solvent content, sulphate content and mannitol content are separate quality attributes and should be interpreted together

GHK-CU Product Overview

Our GHK-CU research-grade copper tripeptide formulation is supplied for controlled scientific laboratory investigation, analytical method development, peptide characterisation, high-performance liquid chromatography assessment, mass-spectrometry workflows, copper-content analysis and formulation research. The peptide component comprises the defined tripeptide sequence glycyl-L-histidyl-L-lysine, commonly abbreviated as GHK.

The finished lyophilised material is formulated with a copper(II) sulphate source and a mannitol-containing laboratory matrix. No cosmetic or food dyes are intentionally added. The white to off-white appearance of the dry presentation reflects the formulated matrix and must not be interpreted independently as evidence of copper concentration, peptide purity or complex formation.

Product identity, chromatographic purity, net peptide content, copper content, peptide-to-copper ratio, complexation status, sulphate content, mannitol content, water content, residual solvents, bacterial endotoxin results and other analytical specifications should be confirmed using the applicable batch Certificate of Analysis. Chromatographic peptide purity should not automatically be interpreted as equivalent to total GHK-Cu complex content or total formulated material content.

For the majority of routine analytical, investigative and general laboratory work, the Regular GHK-CU specification remains highly suitable. The premium black-and-gold ULTIMATE GHK-CU option uses a GHK peptide component subjected to an additional preparative high-performance liquid chromatography purification stage and applies a more stringent bacterial endotoxin and lipopolysaccharide testing specification for scientific projects requiring enhanced quality-control parameters.
