GHK-Cu (copper peptide)

GHK is glycyl-L-histidyl-L-lysine, originally isolated from human plasma. It binds copper(II) through the histidine imidazole nitrogen, the N-terminal amine and a backbone nitrogen, forming a defined square-planar complex — and that complex behaves differently from the uncomplexed peptide. Copper matters here because it's a required cofactor for lysyl oxidase, the enzyme that cross-links collagen and elastin. Plasma GHK has been reported to decline with age, which is much of why the field exists.

GHK-Cu is a copper-bound tripeptide research compound referenced in laboratory studies of matrix-remodeling and copper-dependent signaling. It is used in controlled research models examining collagen and extracellular-matrix pathways, antioxidant-signaling mechanisms, and cellular-remodeling behavior. Within preclinical frameworks, GHK-Cu is investigated for its copper-transport properties and its influence on gene-expression pathways associated with tissue remodeling and repair signaling, all within controlled laboratory environments.

Strictly for in-vitro, cell-based, and preclinical laboratory research applications. No therapeutic, diagnostic, or clinical claims are made or implied.

What is GHK-Cu (copper peptide) used for?
GHK-Cu is supplied for laboratory and preclinical research involving extracellular-matrix signaling, copper-dependent enzymatic pathways, and tissue-remodeling mechanisms. It is not intended for human or veterinary use, therapeutic application, or diagnostic purposes.

Who is eligible to purchase GHK-Cu (copper peptide)?
GHK-Cu (copper peptide) is sold exclusively to qualified researchers and licensed laboratories. By purchasing, buyers confirm they are knowledgeable in handling research-use-only (RUO) materials and will use the product in compliance with applicable regulations.

Is GHK-Cu (copper peptide) approved for human or veterinary use?
No. This product is supplied strictly as a research material and is not approved for human or veterinary use, ingestion, diagnosis, or treatment of any condition.

What purity and quality standards are used?
Each batch is manufactured to high-purity standards and undergoes analytical verification and quality-control review. A batch-specific Certificate of Analysis (COA) is provided to document identity, purity, and applicable testing.

How should GHK-Cu (copper peptide) be stored and handled?
It should be stored under controlled laboratory conditions, protected from heat, moisture, and direct light, and handled following standard laboratory protocols for research materials. Where applicable, avoid repeated freeze-thaw cycles.

Why does the vial appear nearly empty?
Research materials are supplied by analytical mass rather than visible volume. Contents may appear minimal within the container while still meeting the labeled specifications. This is normal for high-purity research materials.

Is documentation provided with each order?
Yes. Each batch is accompanied by a batch-specific Certificate of Analysis (COA) and supporting documentation to support quality assurance, batch traceability, and recordkeeping.

Can GHK-Cu (copper peptide) be used in combination studies?
In laboratory settings, GHK-Cu (copper peptide) may be evaluated alongside other research materials as part of structured experimental study designs. Any combination research should be conducted under controlled laboratory conditions and established analytical research protocols.

For laboratory and research use only. Not for human or veterinary use or consumption. Sold only to qualified researchers.

A Certificate of Analysis is issued for every lot and matched to the lot number printed on your vial. Identity is confirmed by mass spectrometry and purity by HPLC, with third-party ISO-accredited verification available on request. A Safety Data Sheet (SDS) is available for every product.

Orders are processed and shipped promptly via tracked courier. Materials ship lyophilized and remain stable in transit; on arrival, store as indicated on the vial — typically refrigerated or frozen and protected from light — for maximum stability.
