GHK-Cu 100mg

Compound Overview

GHK-Cu 100mg is a lyophilized copper-peptide complex supplied by Amino Apex for qualified laboratory research. This 100mg preparation contains GHK-Cu, a coordination complex formed when the naturally occurring tripeptide glycyl-L-histidyl-L-lysine (GHK) binds a copper ion. GHK has been identified in human biological fluids and investigated for its involvement in copper transport, extracellular-matrix regulation, fibroblast activity, cellular signaling, and tissue-remodeling processes.

Research involving GHK-Cu has examined its influence on collagen and glycosaminoglycan synthesis, endothelial responses, angiogenesis-associated signaling, fibroblast function, antioxidant pathways, and gene-expression patterns. These properties have made the complex a subject of biochemical, cellular, dermatological, and regenerative-biology research.

Published scientific literature has investigated GHK-Cu in relation to copper coordination, cellular signaling, gene-expression patterns, and extracellular-matrix regulation. A comprehensive overview of these research areas is presented in the 2018 peer-reviewed GHK-Cu scientific review published in the International Journal of Molecular Sciences. The review discusses experimental findings and proposed biological mechanisms. Additional laboratory research has examined the influence of GHK-Cu on collagen synthesis in cultured fibroblasts. These findings are documented in the 1988 GHK-Cu fibroblast and collagen synthesis study published in FEBS Letters. The findings concern laboratory cell cultures and do not establish therapeutic effectiveness in humans.

Molecular & Structural Research

GHK is composed of three amino-acid residues:

Glycine – Histidine – Lysine (Gly-His-Lys)

The histidine-containing tripeptide has a strong affinity for copper(II) ions, producing the coordination complex commonly referred to as GHK-Cu or copper tripeptide. Copper coordination is considered an important component of the peptide's biochemical behavior and has been investigated in relation to copper homeostasis, peptide-metal interactions, and cellular signaling.

Experimental studies have also examined GHK-Cu in relation to matrix metalloproteinases, tissue inhibitors of metalloproteinases, collagen production, glycosaminoglycan synthesis, VEGF-associated signaling, and fibroblast growth-factor pathways.

Research Applications

GHK-Cu may be studied in appropriately designed laboratory research involving:

• Copper-peptide coordination
• Peptide-metal interaction studies
• Fibroblast-response research
• Collagen-associated cellular processes
• Extracellular-matrix regulation
• Glycosaminoglycan research
• Cell migration studies
• Endothelial cell-response research
• Angiogenesis-associated signaling
• VEGF and FGF-associated pathways
• Oxidative-stress research
• Gene-expression studies
• Cellular remodeling investigations
• Analytical peptide characterization

These categories reflect areas examined in the scientific literature and do not constitute therapeutic or clinical-use recommendations.

Preclinical Research Context

Research involving GHK and GHK-Cu spans in-vitro cellular systems, animal models, biochemical investigations, and limited human topical skin studies. Experimental work has examined effects on fibroblast behavior, extracellular-matrix components, endothelial signaling, angiogenesis, oxidative-stress pathways, and gene expression.

A substantial portion of the mechanistic evidence remains preclinical, particularly for biological effects outside topical skin research. Results from cellular and animal models should therefore not be assumed to establish clinical safety, efficacy, or therapeutic effects in humans.

Analytical Documentation

Amino Apex provides batch-specific analytical documentation for tested lots. Individual lot documentation may include chromatographic purity analysis and other analytical information associated with the tested sample.

Because analytical characteristics may differ by production lot, the Certificate of Analysis for the applicable batch should be used as the source of measured purity and quality-control results.

Refer to the COA panel on this page or the Amino Apex COA Library for available batch documentation.
