What Is GHK-Cu?
GHK-Cu is a copper peptide supplied by Peptegrity for research and educational purposes. This page provides a factual educational overview of GHK-Cu, including its classification, biological target, research background, terminology and published study context. It is not a product page and does not provide dosing instructions, treatment recommendations or personal-use guidance.
Type of compound
GHK-Cu is classified as a copper-binding tripeptide complex consisting of the amino acid sequence glycyl-L-histidyl-L-lysine (GHK) bound to a copper ion (Cu2+) [7]. It is a naturally occurring peptide found in human blood plasma and other bodily fluids [7].
Biological target and mechanism
The biological activity of GHK-Cu is largely mediated through its interaction with cellular pathways involved in tissue maintenance. Research indicates it can influence fibroblast activity, specifically modulating the synthesis of collagen [2] and regulating the expression of matrix metalloproteinases [3].
Research background
GHK-Cu has been a subject of scientific interest due to its potential role in tissue repair and extracellular matrix remodeling. Early research sought to characterize how this specific copper-peptide complex interacts with cellular cultures to affect structural protein expression [2][3].
Current research and development status
GHK-Cu remains an investigational compound utilized strictly in laboratory, preclinical, and clinical research settings. It is currently the subject of ongoing studies, such as investigations into its effects on wound healing models [6].
Published research context
Published literature investigates the peptide across various models, including fibroblast cultures [2][3], rat ligament reconstruction studies [5], and studies on skin cell behavior [4]. Recent reviews summarize the peptide's history and its broader role in aging research [1].
Relevant terminology
In scientific literature, GHK-Cu is frequently referred to as a copper-peptide or a glycyl-L-histidyl-L-lysine-copper complex. The term 'peptide' refers to a short chain of amino acids, while the 'Cu' denotes the chelated copper ion essential to its chemical structure [7].
Storage and handling terminology
Research-grade peptides are typically stored in lyophilized (freeze-dried) powder form at -20°C or -80°C to maintain chemical stability. Once reconstituted, peptides are sensitive to degradation and are typically kept in buffered solutions at refrigerated temperatures for limited durations.
Testing and Certificate of Analysis (COA)
A Certificate of Analysis (COA) for research peptides provides verification of purity, usually determined via High-Performance Liquid Chromatography (HPLC), and molecular weight confirmation via Mass Spectrometry. These documents confirm that the compound meets standardized laboratory quality specifications before use in experimental protocols.
Regulatory status
GHK-Cu is not approved by the FDA, TGA, or any other global regulatory authority for human therapeutic use. It is categorized strictly for research and laboratory purposes and must not be distributed as a medicine.
