About This Compound

Deep technical insights for clinical research

Synthesis & Purity Overview

GHK-Cu is a naturally occurring copper-binding tripeptide (Gly-His-Lys) complexed with a Cu²⁺ ion. First identified in human plasma by Pickart and Thaler in 1973, it is synthesized via SPPS with controlled copper complexation and HPLC purification.
Purity: >99% by HPLC
Form: Lyophilized powder (blue)
Storage: −20°C, desiccated, protect from light
Reconstitution: Sterile water
GHK-Cu is one of the most extensively studied copper peptides in dermatological and wound healing research. It stimulates collagen I and III synthesis, glycosaminoglycan production, and metalloproteinase remodeling — making it a reference compound in extracellular matrix regeneration and skin aging studies.
Batch Consistency

Intra-batch variance below 0.2% across copper content, peptide composition, and complex stability analysis.

Contaminant Profile

Zero detection of free copper ions, heavy metals, endotoxins, residual solvents, and microbial contaminants.
