GHK-Cu (Copper Tripeptide-1) research compound — wholesale

For research use only · Not for human consumption · Not for veterinary use. This product is supplied for in-vitro research, analytical method development, and laboratory reference standard use only. Not approved for human or veterinary administration. Buyer is responsible for end-use classification in the destination jurisdiction.

Overview

GHK-Cu is the copper-bound tripeptide Gly-His-Lys, also referenced as Copper Tripeptide-1 or the GHK copper complex. The tripeptide is a naturally occurring fragment of the alpha-2 chain of type I collagen, and the copper-complex form is the species that has been the most extensively studied in cell-based research. The compound is supplied as a research-grade lyophilized powder with the characteristic blue colour of the Cu²⁺ complex, intended for in-vitro cell-based assays of extracellular matrix remodelling, copper-dependent enzyme cofactor activity, and analytical reference-standard work. SPK Pharma India supplies GHK-Cu for research and analytical applications only, with the 50 mg and 100 mg vial formats positioned for in-vitro research laboratories, distributors, and contract manufacturers.

Specifications

Research context

GHK-Cu has been studied in cell-based research on extracellular matrix remodelling, the role of copper as a cofactor for lysyl oxidase and related enzymes, and the influence of the tripeptide on cell migration and matrix metalloproteinase activity in defined cell-based systems. The Cu²⁺ complex is the active research species, and the stoichiometry of the complex is confirmed by UV-Vis spectroscopy (the d-d transition around 600 nm is characteristic of the GHK:Cu complex).

The compound is also used as an analytical reference standard for LC-MS and HPLC method development in laboratories that study copper-peptide complexes, matrix metalloproteinase activity, and collagen biosynthesis. SPK Pharma India does not make therapeutic, clinical, diagnostic, or dosing claims for this product. The compound is supplied strictly for in-vitro research, analytical method development, and reference-standard work.

For researchers new to the compound, the standard analytical reference points are CAS 89030-95-5, the three-amino-acid sequence, the stoichiometric Cu²⁺ complex, the calculated molecular weight of 403.93 g/mol, the characteristic blue colour of the lyophilized powder, and the documented purity threshold (≥99% HPLC).

Packaging and supply

• 50 mg research vial — for method development, cell-based assays, and reference-standard qualification. Standard MOQ: 5 vials.
• 100 mg research vial — for ongoing research programmes with higher per-assay demand. Standard MOQ: 2 vials.
• Bulk pack — on application, for annual supply contracts and recurring orders.

Distributor pricing is available on application. Annual supply contracts with scheduled recurring dispatch are available for repeat buyers. Lead time for in-stock SKUs is typically 5 business days from purchase order confirmation; lead time for scheduled production is typically 4 to 6 weeks.

Quality and documentation

Every lot of GHK-Cu ships with a lot-matched Certificate of Analysis documenting identity (mass spectrometry, UV-Vis spectroscopy, and amino acid analysis), purity (HPLC), appearance, lot number, and synthesis batch reference. A representative sample of every lot is independently verified by a third-party analytical laboratory before release. MSDS is supplied with every shipment. The COA template, the lot-traceability workflow, and the third-party verification scope are documented on the Quality page.

Storage and handling

• Store at -20°C in the original sealed container.
• Protect from light and moisture. The Cu²⁺ complex is light-sensitive; prolonged exposure to ambient light may affect the complex.
• Allow the sealed container to reach room temperature before opening, to avoid condensation.
• Reconstitute in sterile, low-endotoxin research-grade water or in a mild buffer at the working concentration required by the assay. Avoid strong chelators (EDTA) in the reconstitution buffer, as they will compete with GHK for Cu²⁺.
• Do not refreeze once reconstituted; aliquot and store at working concentration.

Shipping

GHK-Cu is shipped lyophilized in sealed vials within temperature-validated packaging. International lanes are routed through dedicated life-science logistics partners with cold-chain handling. Standard dispatch is within 5 business days of purchase order confirmation. SPK Pharma India ships to the United States, the European Union, the United Kingdom, Canada, MENA, APAC, and LATAM.
