GHK-Cu: Compound Overview

GHK-Cu is a tripeptide composed of glycine, L-histidine, and L-lysine, with a high-affinity binding site for copper(II) ions. It occurs endogenously in human plasma, saliva, and urine, with plasma concentrations that appear to decline with age — a pattern that has generated considerable interest in biogerontology research.

In its synthesized form, GHK-Cu is produced as a lyophilized research compound. It has been studied in rodent models, cell culture systems, and gene expression platforms across a range of research areas including skin biology, wound healing, anti-fibrotic signaling, and nervous system function.

Mechanism of Action in Preclinical Models

Pickart and Margolina (2018) conducted a comprehensive review of GHK-Cu's activity, synthesizing data from multiple programs. Their analysis identified GHK-Cu as modulating the expression of over 4,000 genes in human cell lines, with observed effects on pathways governing collagen and glycosaminoglycan synthesis, anti-inflammatory signaling, and antioxidant gene upregulation.

What to Look for in a Research Peptide Supplier

  • HPLC Purity and Identity Testing: Should confirm both the identity of the compound and its purity via UV peak integration.
  • Endotoxin Screening: LAL endotoxin testing should be documented per batch.
  • Batch-Specific Certificate of Analysis: Each lot should carry an independently issued COA.
  • Third-Party Canadian Laboratory Verification: Domestic third-party certification ensures consistent, auditable testing.
