Available at The Peptide Store, this high-mass configuration is engineered for laboratories conducting large-scale formulation studies, copper-mediated cellular pathway analysis, and transdermal vehicle stability investigations. For research use only. Not for human or veterinary use. Not for clinical, diagnostic, or consumptive applications.

Product Overview

GHK-Cu is among the most extensively studied carrier peptides in contemporary regenerative science, recognized for its role as a molecular probe in neuroprotective, anti-aging, and dermatological research contexts. The Peptide Store supplies this topical-grade peptide in a 200mg raw powder format, offering researchers a robust biochemical platform for high-throughput experimental design. Its copper-complexed tripeptide architecture enables precise investigation of localized copper bioavailability, genetic upregulation cascades, and ECM structural remodeling without inducing cytotoxic effects at physiologically relevant concentrations studied in vitro.

Peptide Structure & Amino Acid Sequence

GHK-Cu is composed of a tripeptide sequence — Glycine – L-Histidine – L-Lysine — complexed with a divalent copper ion (Cu²⁺). This configuration confers the molecule with a distinctive square-planar coordination geometry, facilitating stable copper chelation. The imidazole nitrogen of histidine and the terminal amine groups of glycine and lysine serve as primary coordination sites, enabling selective and reversible copper binding. The molecular formula is C₁₄H₂₄CuN₆O₄, with a molecular weight of approximately 403.92 g/mol. The CAS number associated with GHK-Cu is 49557-75-7.

Purity & Analytical Verification (HPLC & MS)

Every batch of GHK-Cu supplied by The Peptide Store undergoes rigorous analytical testing to confirm a minimum purity of ≥98%. High-Performance Liquid Chromatography (HPLC) is employed to quantify peptide content and detect trace impurities, while Mass Spectrometry (MS) confirms molecular identity and verifies the copper coordination complex integrity. These dual-method verification protocols ensure that researchers receive a consistent, analytically characterized product suitable for reproducible experimental outcomes across multi-batch studies.

Quality Control & Lyophilization Integrity

GHK-Cu is produced under controlled manufacturing conditions with strict quality control checkpoints at each stage of synthesis, purification, and lyophilization. The lyophilization process removes residual moisture while preserving the structural integrity of the copper-peptide complex, resulting in a stable, free-flowing powder with extended shelf stability. Batch-specific Certificates of Analysis (CoA) are available upon request, documenting HPLC purity data, MS confirmation, and physical appearance specifications.

Safety, Handling & Laboratory Precautions

GHK-Cu should be handled exclusively by trained laboratory personnel in compliance with institutional biosafety protocols. Standard laboratory personal protective equipment (PPE) — including nitrile gloves, safety glasses, and a lab coat — should be worn during handling. As a copper-containing compound, appropriate containment and disposal procedures must be followed in accordance with local environmental and laboratory safety regulations. This product is strictly a research reagent and must not be used outside of a controlled laboratory environment.

Reconstitution, Packaging & Storage

GHK-Cu 200mg is packaged in a sealed, inert container appropriate for long-term raw powder preservation. For in vitro research applications, this peptide is compatible with standard aqueous reconstitution buffers and topical vehicle systems. Researchers should consult peer-reviewed literature for formulation guidance appropriate to their specific experimental design. Store at −20°C in a dry, light-protected environment. Once reconstituted for in vitro use, aliquot promptly and avoid repeated freeze-thaw cycles to maintain analytical integrity.

Intended Research Use & Market Positioning
