GHK-Cu Copper Peptide Powder 1g

GHK-Cu Copper Peptide Powder 1g is a cosmetic-grade copper peptide raw material produced by our factory, formed as a 1:1 chelation complex between the tripeptide GHK (glycyl-histidyl-lysine) and copper ions, supplied as blue powder. GHK-Cu, also known as Copper Tripeptide-1, is a small peptide naturally present in human plasma. The histidine imidazole group and lysine amino group in its molecular structure provide a stable coordination environment for copper ions, enabling gentle delivery and release of copper ions under physiological conditions. Our GHK-Cu Copper Peptide Powder 1g uses solid-phase synthesis to prepare the tripeptide backbone, then forms the complex through precisely controlled copper chelation process, purified then dried into powder, finished as blue to blue-violet crystalline powder with good water solubility.

 

In production of GHK-Cu Copper Peptide Powder 1g, we focus on controlling copper chelation ratio and product color stability. The chelation reaction between GHK tripeptide and copper ions requires precisely controlled pH, temperature, and molar ratio conditions. Too few copper ions lead to pale product color and insufficient effective copper content; too many copper ions produce free copper precipitation affecting product purity. We ensure the chelation reaction reaches the optimal endpoint by online monitoring of UV absorption and color changes in the reaction solution. Purified peptide-copper complex solution is desalted, sterile-filtered, quantitatively dispensed, then low-temperature dried to obtain loose powder. Each batch undergoes appearance, copper content, pH, and microbial limit testing with COA report. This product is widely used in anti-aging, repair, and antioxidant cosmetic formulations, and is one of the commonly used active peptide raw materials for global skincare brands.

Our factory has over 20 years of technical accumulation in peptide synthesis and production, covering a total area of 25,000 square meters, with a core production area of a Class 100,000 GMP cleanroom (12,000 sqm), equipped with independent R&D laboratories, quality control testing centers, and raw material storage areas. The factory employs 118 people, including 25 R&D technicians, 35 QC inspectors, and 58 production workers. We have established an integrated fully automated solid-phase peptide synthesis production line using a closed production mode with automatic temperature and pH control, covering the entire process from amino acid charging, solid-phase synthesis, crude cleavage, chromatographic purification, desalting/concentration, sterile filtration, vacuum lyophilization to aseptic filling. The production line supports laboratory-scale R&D, pilot-scale amplification, and large-scale industrial mass production, with a stable monthly capacity of over 30,000 vials, and multiple GMP lines can be scheduled in parallel to ensure on-time delivery of large orders. We have long focused on R&D and production of cosmetic-grade bioactive peptides, with main products covering copper peptide, acetyl hexapeptide, various signal peptides, tripeptides, tetrapeptides and more. Product impurity profile is stable with minimal inter-batch variation, with long-term stable supply to multiple overseas cosmetic raw material traders in Europe, America, Southeast Asia, and North America.

We implement full-process quality control for GHK-Cu Copper Peptide Powder 1g. Raw material stage: incoming inspection of each batch of Fmoc-protected amino acids, resin, and copper salts; production stage: QC points at key processes including solid-phase synthesis, copper chelation, purification, drying, with intermediate product tracking; finished stage: appearance inspection, copper content determination, pH testing, solubility testing, and microbial limit testing. Each batch comes with COA report, 100% appearance inspection before packaging, customer-designated third-party inspection supported. Our 35-person QC team is equipped with HPLC, mass spectrometry, atomic absorption spectrophotometer, and UV spectrophotometer, ensuring copper content and batch consistency of each batch.

GHK-Cu Copper Peptide Powder 1g uses sealed bottle packaging, with outer shock-absorbing material securing, then reinforced cartons, effectively reducing breakage and moisture risk during long-distance transport. We support DDP terms and provide multi-channel logistics covering spot, bulk, and cross-border customized shipments. Each order comes with complete qualification documents including COA report and MSDS safety data sheet. After shipment, tracking numbers are synced and status continuously updated for full traceability. For large orders, outer carton labeling, packing methods, and moisture-proof packaging can be customized.
