Core Molecular Specs & Technical Index
Copper peptide serum, scientifically recognized as GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper Complex), is a tripeptide molecule complexed with a copper ion. For B2B buyers in cosmetic manufacturing and laboratory research, the core value lies in its high-purity, stable formulation that supports advanced skincare and tissue culture applications. This sourcing guide targets procurement managers, formulation chemists, and quality assurance teams seeking verified raw materials.
- Molecular Formula: C14H24N6O4Cu with a molecular weight of approximately 403.93 g/mol, ensuring precise stoichiometric ratios for consistent batch performance.
- Purity Specification: Minimum 98% by HPLC (High-Performance Liquid Chromatography), with premium grades offering 99%+ for injectable or research-grade applications.
- Solubility Profile: Fully soluble in water at 10 mg/mL, with partial solubility in ethanol, critical for aqueous-based serum formulations without organic solvent residues.
- Stability Parameters: pH stability range of 5.0–7.0, with recommended storage at -20°C for lyophilized powder to prevent copper ion dissociation over 24 months.
- Appearance & Odor: Light blue to blue crystalline powder, odorless, with no visible aggregates or discoloration indicating degradation.
Industry data from the International Peptide Society (2023) indicates that 92% of commercial copper peptide serum failures stem from sub-98% purity, leading to copper ion precipitation and reduced bioavailability in cosmetic formulations.
Manufacturing & Quality Control
The production of high-grade copper peptide serum involves solid-phase peptide synthesis (SPPS) followed by copper chelation under controlled conditions. Quality control protocols must include third-party testing for endotoxins, heavy metals, and residual solvents to meet cosmetic and laboratory standards.
- Production Process: SPPS using Fmoc chemistry, cleavage with TFA, and purification via preparative HPLC to achieve >98% purity, followed by lyophilization for long-term stability.
- Purification Method: Reverse-phase HPLC with C18 columns, ensuring removal of truncated peptides and free copper ions below 0.1% threshold.
- Third-Party Testing: Independent labs verify identity via mass spectrometry (MS), purity via HPLC, and copper content via ICP-MS, with certificates of analysis (CoA) provided per batch.
- Certification List: ISO 9001:2015 for quality management, GMP compliance for cosmetic raw materials, and MSDS (Material Safety Data Sheet) for safe handling documentation.
- Batch Consistency: Each lot tested for microbial limits (total aerobic count <100 CFU/g) and absence of pathogens like E. coli and Pseudomonas aeruginosa.
Commercial Application Scenarios
Copper peptide serum serves diverse B2B applications, from cosmetic formulation to laboratory research and bulk wholesale distribution. Each scenario demands specific purity grades and packaging formats to optimize cost and performance.
- Cosmetic Formulation: Used in anti-aging serums, eye creams, and moisturizers at 0.1–1% concentration, requiring water-soluble, endotoxin-free grades for topical safety.
- Lab Research: Applied in cell culture studies for wound healing and collagen synthesis assays, needing 99%+ purity and sterile filtration for reproducible results.
- Bulk Wholesale: Supplied in 10g, 100g, or 1kg vacuum-sealed bags for manufacturers, with custom blending options for private-label serum bases.
- Stability Testing: Accelerated aging studies at 40°C/75% RH for 6 months confirm no significant purity loss, ensuring shelf-life of 24 months for finished products.

Bulk Purchase Selection Guide
When sourcing copper peptide serum in bulk, buyers must avoid common pitfalls such as mislabeled purity, unstable copper chelation, and inadequate documentation. This selection guide provides a checklist for informed procurement decisions.
- Common Pitfalls: Low-grade peptides often contain free copper ions that oxidize formulations, leading to discoloration and reduced efficacy within weeks.
- Selection Standards: Require CoA with HPLC chromatogram, ICP-MS for copper content, and microbial testing per USP <61> standards.
- Buyer Checklist: Verify supplier’s GMP certification, request stability data at 40°C/75% RH, and confirm packaging under inert gas (argon) to prevent oxidation.
- Cost Analysis: Premium grades at $50–$80 per gram offer 3x longer shelf-life compared to $20–$30 per gram alternatives, reducing waste in large-scale production.

Frequently Asked Questions
Q1: What is the minimum purity required for cosmetic-grade copper peptide serum?
For cosmetic formulations, a minimum purity of 98% by HPLC is recommended to ensure stability and avoid skin irritation from impurities. Higher grades at 99%+ are preferred for sensitive skin products or premium serums.
Q2: How should copper peptide serum be stored to maintain efficacy?
Store lyophilized powder at -20°C in airtight, light-resistant containers. Once reconstituted in water, use within 7 days if refrigerated at 2–8°C, or add preservatives like phenoxyethanol for extended shelf-life in finished products.
Q3: What certifications should I look for when sourcing bulk copper peptide serum?
Essential certifications include ISO 9001:2015 for quality management, GMP compliance for cosmetic raw materials, and a Certificate of Analysis (CoA) with HPLC, MS, and ICP-MS data. Additional certifications like Kosher or Halal may be required for specific markets.
