GHK-Cu (Copper Tripeptide-1) for research. Sourced directly from China, HPLC verified, purity tested per batch. Longevity and skin research applications.
GHK-Cu is the copper peptide most in demand across both research and cosmetic-formulation channels. For china peptide buyers, GHK-Cu presents a specific sourcing challenge: copper content, peptide content, and appearance are all commonly misreported by intermediaries. We supply GHK-Cu with manufacturer specifications that state what is actually in the vial, because a copper peptide with unverified copper content is not a research tool — it is a liability.

Compound Profile
GHK-Cu (Glycyl-L-Histidyl-L-Lysine copper(II)) is a naturally occurring copper chelating tripeptide first isolated from human plasma by Loren Pickart in 1973. The complex consists of the tripeptide GHK (Gly-His-Lys) coordinated to a copper(II) ion — a configuration that enables cellular uptake via copper chelation and interaction with a broad range of extracellular matrix and intracellular receptors. Plasma concentrations of GHK-Cu decline significantly with age: from approximately 200 ng/mL at age 20 to under 80 ng/mL by age 60, making it a subject of regenerative biology and aging research. Preclinical and in vitro research has examined GHK-Cu’s influence on fibroblast proliferation, collagen and glycosaminoglycan synthesis, matrix metalloproteinase regulation, wound remodeling, and stem cell gene expression. Its small molecular size and copper-chelating structure enable tissue penetration that larger peptides cannot achieve. Peptides of China supplies GHK-Cu as a lyophilized powder, synthesized to 99%+ purity and verified by HPLC and Mass Spectrometry. Every batch is tested by the manufacturer for purity and concentration as part of routine quality control. All products are intended for laboratory research use only and are not for human consumption.

Research Areas
Skin, Collagen and Wound Remodeling The majority of GHK-Cu research involves skin biology and extracellular matrix remodeling. In vitro studies have demonstrated stimulation of collagen, elastin, and glycosaminoglycan synthesis in fibroblast cultures. Animal wound models have shown accelerated wound contraction and dermis regeneration. GHK-Cu’s influence on matrix metalloproteinase regulation and DNA repair mechanisms are particular research foci. Hair Follicle Research GHK-Cu has been studied in the context of hair follicle biology, including follicle enlargement and potential prolongation of the anagen (growth) phase in animal and in vitro models. This has made it a subject of dermatological research on androgenic alopecia and hair follicle cycling at the cellular level. Antioxidant and Anti-inflammatory Activity GHK-Cu demonstrates superoxide dismutase-mimetic antioxidant activity in vitro and has been shown to modulate expression of multiple anti-inflammatory genes. It has been proposed as an endogenous regulator of inflammation through copper-mediated redox signaling and has been investigated for its role in stem cell gene expression modulation. ## Sourcing GHK-Cu From China
GHK-Cu is available through our platform as a china peptide sourced directly from an established Chinese manufacturer. Three points define how we handle it:
- Factory-direct, not trader-sourced. We confirm availability and specification with the manufacturer before the order is confirmed. There is no intermediary resale of unknown-origin vials in this catalog.
- Specification before shipment. The purity and concentration specification shown on this page is the manufacturer’s batch specification. Product-specific quality-control information travels with the order.
- Research-use discipline. Like every listing in our catalog, GHK-Cu is supplied for laboratory research use only, under strict research-use terms.
For buyers comparing chinese peptides suppliers, the practical test is whether the seller can name the manufacturer and show the batch documentation. We work the other way around: the manufacturer and the documentation are the offer. Browse the full catalog or see how sourcing works.
