2. Professional Product Introduction

Copper Tripeptide-1 (GHK-Cu, CAS: 89030-95-5) is a highly active natural copper-chelated tripeptide endogenous to the human body and a classic star ingredient for high-end skin repair and anti-aging skincare. Different from copper-free GHK monomers, GHK-Cu forms a stable chelated structure through precise binding of GHK tripeptide and copper ions, delivering dual physiological benefits of peptide bioactivity and trace copper ion regulation with stronger efficacy and higher repair efficiency. It precisely activates the proliferation of skin fibroblasts, significantly promotes the synthesis of collagen, elastin and glycosaminoglycans, fundamentally plumps the skin and fades fine lines and sagging. It also exhibits excellent anti-inflammatory and soothing properties, repairing damaged skin barriers, relieving redness and sensitivity, and accelerating epidermal wound healing. Its powerful antioxidant system efficiently scavenges free radicals, resists photoaging and oxidative damage, and improves dull and rough skin texture. Featuring mild properties and dual effects of repair and anti-aging, GHK-Cu is widely applied in high-end repair and anti-aging skincare products, postoperative repair formulas and sensitive skin care formulations, and serves as a core research tool for skin regeneration, wound healing and skin aging mechanism studies.

3. Product Description

This product is high-purity research and cosmetic-grade GHK-Cu lyophilized powder, fully compliant with the official standard substance structure of CAS 89030-95-5. Adopting mature and rigorous solid-phase peptide synthesis technology, it completes accurate assembly of the full-length GHK sequence, followed by standardized high-precision copper ion chelation to form a complete and stable complex structure with no free copper ions or unchelated monomer residues. No sequence errors or structural defects are detected in the finished product. Multi-stage high-precision preparative HPLC thoroughly removes synthetic residues, free ions, isomeric impurities and process by-products, ensuring stable HPLC purity above 98.0%, uniform batch color tone and consistent complex activity with excellent experimental and formula repeatability. The exclusive copper chelated structure greatly enhances the bioavailability and skin permeability of tripeptides, endowing GHK-Cu with far superior repair, anti-aging and anti-inflammatory activity compared with ordinary copper-free GHK tripeptides. With ultra-low cytotoxicity and excellent biocompatibility, the product is non-irritating and fully suitable for in vitro skin cell regeneration experiments, wound healing models, skin anti-inflammatory and antioxidant mechanism verification, and high-end anti-aging repair cosmetic formula development, meeting the strict quality standards of both high-end scientific research and commercial raw material production.
