Introduction
GHK Cu peptide serum, also known as copper tripeptide-1, is a high-purity bioactive peptide widely used in cosmetic formulations and laboratory research. This article serves as a comprehensive sourcing guide for B2B buyers—including cosmetic manufacturers, contract labs, and raw material distributors—seeking bulk supply of GHK Cu peptide serum. The core value lies in understanding purity specifications, manufacturing standards, and quality control to ensure consistent performance in end products.
Core Molecular Specs & Technical Index
GHK Cu peptide serum is a copper-bound tripeptide (glycyl-histidyl-lysine) with a molecular weight of approximately 403.5 g/mol. Its unique structure enables high affinity for copper ions, which is critical for biological activity in cosmetic and research applications. Below are the key technical specifications for bulk procurement.
- Purity: ≥98% by HPLC, with premium grades offering ≥99% for research-grade applications.
- Appearance: White to off-white lyophilized powder, free of visible aggregates or discoloration.
- Solubility: Readily soluble in water at 10 mg/mL, forming a clear blue solution due to copper content.
- Storage: Store at -20°C in airtight, light-protected containers; stable for 24 months under recommended conditions.
- pH Range: Optimal stability at pH 5.0–6.5 for aqueous formulations.
Industry data from the Peptide Research Institute (2023) indicates that GHK Cu peptide serum with ≥98% purity shows 40% higher stability in cosmetic bases compared to lower-grade alternatives, reducing degradation during shelf life.
Manufacturing & Quality Control
Bulk production of GHK Cu peptide serum follows a multi-step process to ensure batch-to-batch consistency. Solid-phase peptide synthesis (SPPS) is the standard method, using Fmoc chemistry to build the tripeptide chain. After cleavage and deprotection, copper chelation is performed under controlled pH to form the stable copper complex.
Purification via preparative HPLC achieves target purity levels, followed by lyophilization to yield a dry powder. Quality control includes HPLC analysis for purity, mass spectrometry for molecular weight confirmation, and ICP-MS for copper content verification. Third-party testing by ISO 17025 accredited labs is recommended for bulk orders.
- Certification: COA (Certificate of Analysis) with HPLC chromatogram and copper assay.
- Heavy Metal Testing: Lead, arsenic, cadmium, and mercury below 1 ppm each.
- Microbiological Limits: Total aerobic count <100 CFU/g, yeast and mold <10 CFU/g.
- Endotoxin Testing: <0.5 EU/mg for injectable-grade applications.
Commercial Application Scenarios
GHK Cu peptide serum is a versatile raw material for multiple B2B sectors. In cosmetic formulation, it is incorporated into anti-aging serums, eye creams, and moisturizers at concentrations of 0.1–1.0% by weight. Labs use it for cell culture studies, particularly in wound healing and dermal fibroblast research. Bulk wholesale buyers often source 10g to 1kg quantities for product development pipelines.
For example, a cosmetic manufacturer may blend GHK Cu peptide serum with hyaluronic acid and vitamin C to create a premium serum. In lab research, it serves as a positive control for copper-dependent enzyme assays. The bulk supply chain typically requires cold chain shipping for long-distance orders to maintain stability.

Bulk Purchase Selection Guide
When sourcing GHK Cu peptide serum in bulk, avoid common pitfalls such as relying solely on price or incomplete documentation. Low-cost suppliers may offer impure batches with copper oxide contamination, which appears as a greenish tint rather than the standard blue solution. Always request a COA and third-party HPLC data before committing to large orders.
Selection standards include verifying the supplier’s manufacturing facility (GMP certification preferred), checking batch consistency through multiple samples, and confirming shipping conditions for cold chain compliance. A buyer checklist should cover purity specs, copper assay, microbiological limits, and storage recommendations.
- Checklist: Request COA with HPLC and mass spec data.
- Checklist: Confirm copper content via ICP-MS report.
- Checklist: Verify endotoxin levels for intended use.
- Checklist: Review supplier’s GMP or ISO 9001 certification.

Frequently Asked Questions
Q1: What is the minimum order quantity for GHK Cu peptide serum bulk supply?
Minimum order quantities typically start at 10 grams for lab-scale research, with bulk discounts available for 100g, 500g, and 1kg orders. Custom quantities can be negotiated for long-term contracts.
Q2: How should GHK Cu peptide serum be stored after opening?
After opening, store the powder at -20°C in a desiccated, light-protected container. For aqueous solutions, use within 24 hours at 2–8°C to prevent degradation. Avoid repeated freeze-thaw cycles.
Q3: Can GHK Cu peptide serum be used in water-based cosmetic formulations?
Yes, it is water-soluble and compatible with most cosmetic bases. However, avoid high pH (>7.0) and strong reducing agents, which can disrupt the copper complex. Recommended use levels are 0.1–1.0% by weight.
