GHK-Cu 500mg (Copper Peptide) (Topical)

GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper Complex) is a naturally occurring tripeptide-copper complex available at The Peptide Store as a bulk topical-grade raw powder at ≥98% purity. Engineered for advanced dermatological, trichological, and extracellular matrix (ECM) remodeling research, this 500mg configuration provides a broad biochemical platform for large-scale formulation and cellular regeneration studies. For research use only. Not for human or veterinary use. Not for clinical, diagnostic, or consumptive applications.

Product Overview

GHK-Cu is one of the most extensively studied carrier peptides in regenerative science. Its unique capacity to chelate copper(II) ions within a compact tripeptide scaffold makes it a highly selective molecular probe for investigating localized copper bioavailability, wound-healing signaling cascades, and ECM remodeling dynamics. The 500mg topical-grade raw powder format offered by The Peptide Store is specifically configured for laboratories requiring substantial raw material volumes for dose-dependent formulation matrices, vehicle viscosity interaction mapping, and long-term structural gene expression studies.

Peptide Structure & Amino Acid Sequence

GHK-Cu is classified biochemically as Glycyl-L-Histidyl-L-Lysine complexed with a divalent copper ion (Cu²⁺). The linear tripeptide sequence — Gly-His-Lys — contains a histidine residue whose imidazole nitrogen, combined with the free N-terminal amine and the lysine side chain, forms a stable coordination complex with Cu²⁺. This tripartite chelation geometry allows GHK-Cu to function as a precision copper carrier, modulating localized metalloprotein activity without inducing cytotoxic ion overload. The CAS number for GHK-Cu is 49557-75-7. Its molecular formula is C₁₄H₂₄CuN₆O₄, with a molecular weight of approximately 403.92 g/mol.

Purity & Analytical Verification (HPLC & MS)

Every batch of GHK-Cu 500mg powder available at The Peptide Store is independently verified to achieve ≥98% purity via reverse-phase High-Performance Liquid Chromatography (HPLC). Mass Spectrometry (MS) confirmation is performed to validate molecular identity and confirm the absence of truncated sequences, deletion peptides, or residual synthesis by-products. Researchers can rely on this dual-verification methodology as a foundation for reproducible experimental design and formulation consistency across large-scale research protocols.

Quality Control & Lyophilization Integrity

GHK-Cu 500mg is produced under stringent quality control conditions. The lyophilization process is carefully optimized to preserve the structural integrity of the copper-peptide complex, minimize oxidative degradation, and maintain consistent reconstitution behavior across research batches. Each lot undergoes batch-level QC review, and certificates of analysis (CoA) are available upon request. Residual moisture content is controlled to fall within acceptable limits for long-term powder stability, ensuring that researchers receive material suitable for demanding analytical and formulation applications.

Safety, Handling & Laboratory Precautions

GHK-Cu 500mg is supplied exclusively as a research-grade raw material. All handling must be performed by trained laboratory personnel in compliance with applicable institutional safety protocols. Standard personal protective equipment (PPE) — including gloves, lab coat, and eye protection — should be worn during weighing and handling. Avoid inhalation of fine powder particles. As with all copper-containing compounds, appropriate waste disposal procedures must be followed in accordance with local environmental regulations. This material is not intended for any form of human or animal administration.

Reconstitution, Packaging & Storage

GHK-Cu 500mg is supplied as a dry lyophilized powder in sealed, research-grade packaging designed to protect against moisture ingress and oxidative degradation. For laboratory dissolution studies, researchers should consult peer-reviewed literature for appropriate aqueous or buffered vehicle selection relevant to their specific experimental design. Recommended storage conditions are at −20°C in a desiccated, light-protected environment. Avoid repeated freeze-thaw cycling to preserve peptide-copper complex integrity. Shelf life is optimized when material is stored under recommended conditions immediately upon receipt.

Intended Research Use & Market Positioning

GHK-Cu 500mg topical-grade raw powder is positioned for use in advanced research settings including dermatological formulation science, trichological ECM studies, wound-healing pathway analysis, and metalloprotein regulatory research. Its bulk 500mg configuration makes it the preferred choice for laboratories conducting large-scale formulation stability trials, multi-variable dose-response experiments, and extended-duration mechanistic studies. The Peptide Store offers this material at a competitive best price for researchers seeking a reliable, high-purity copper peptide source for sale in bulk research quantities.
