GHK-Cu (Copper Peptide): A Comprehensive Research Guide

What Is GHK-Cu?

GHK-Cu, also known as copper peptide GHK-Cu, is a naturally occurring tripeptide consisting of glycine, histidine, and lysine, bound to a copper(II) ion. First identified in human plasma in 1973 by Dr. Loren Pickart, GHK-Cu has become one of the most extensively studied peptides in biomedical research.

The peptide is found naturally in human blood plasma, saliva, and urine, with plasma levels declining significantly with age. At Pept, we provide research-grade GHK-Cu with full certificates of analysis and third-party purity testing.

The Discovery and Structure of GHK-Cu

GHK-Cu was discovered when researchers observed that liver tissue from older individuals behaved differently when exposed to plasma from younger donors. The active component was eventually isolated and identified as GHK-Cu, a small peptide with a strong affinity for copper ions.

The molecular structure consists of just three amino acids, but its copper-binding properties give it unique characteristics that have drawn considerable research attention.

Key Research Areas for GHK-Cu

GHK-Cu has been the focus of hundreds of published research papers across multiple disciplines including dermatological research in skin cell culture models, tissue remodelling studies examining extracellular matrix components, antioxidant research exploring copper-dependent enzyme systems, and hair follicle biology examining effects on follicle cell cultures.

GHK-Cu is sold for research purposes only and is not approved for therapeutic use.

GHK-Cu in Published Literature

Research papers have appeared in journals spanning dermatology, biochemistry, cellular biology, and materials science. Studies have examined the peptide's interactions with various cell types, its effects on gene expression in vitro, and its behaviour in various experimental models. Notably, research has identified that GHK-Cu may influence the expression of a large number of genes in cell culture experiments.

Purity and Quality in GHK-Cu Research

At Pept, our GHK-Cu undergoes comprehensive third-party testing. Every batch ships with a Certificate of Analysis (COA) documenting purity verification via HPLC, molecular weight confirmation via mass spectrometry, amino acid analysis, and endotoxin testing.

Proper Handling and Storage

GHK-Cu should be stored as a lyophilised powder at -20 degrees Celsius for long-term storage. The peptide is sensitive to oxidation due to its copper component, so storage under inert gas is recommended. Once reconstituted, solutions should be stored at 2-8 degrees Celsius and used promptly. Avoid repeated freeze-thaw cycles.
