Core Molecular Specs & Technical Index

BPC-157 peptide, also known as Body Protection Compound-157, is a synthetic pentadecapeptide composed of 15 amino acids. It is primarily sourced by laboratories, cosmetic formulators, and research institutions for its stability and bioactivity in controlled environments. The core value of BPC-157 lies in its high-purity formulation, which ensures consistent results in experimental and cosmetic applications. For B2B buyers, understanding the technical specifications is critical to verifying product integrity and avoiding contamination risks.

Basic Properties and Purity Standards

High-grade BPC-157 peptide typically exhibits a molecular weight of 1419.55 g/mol and a chemical formula of C62H98N16O22. The purity level, measured by High-Performance Liquid Chromatography (HPLC), should exceed 98% for lab-grade material and 99% for cosmetic-grade applications. Impurities such as truncated sequences or residual solvents can compromise experimental outcomes, making purity a non-negotiable factor in sourcing decisions.

Solubility and Storage Requirements

BPC-157 peptide is highly soluble in water and sterile saline, with a solubility of approximately 10 mg/mL at room temperature. For long-term storage, lyophilized powder should be kept at -20°C in airtight, light-resistant containers. Reconstituted solutions must be used within 30 days when refrigerated at 2-8°C. These parameters are essential for maintaining peptide stability and preventing degradation during transport or storage.

Key Technical Specifications

Industry data from the Peptide Research Council indicates that over 85% of peptide sourcing failures in 2023 were linked to purity below 95%, emphasizing the need for rigorous HPLC certification in B2B transactions.

Manufacturing & Quality Control

The production of BPC-157 peptide involves solid-phase peptide synthesis (SPPS), a method that ensures precise amino acid sequencing and high yield. Quality control protocols are implemented at every stage, from raw material verification to final product release, to meet the stringent demands of lab and cosmetic sourcing.

Production Process

SPPS begins with the attachment of the C-terminal amino acid to a resin support, followed by sequential coupling of protected amino acids. After synthesis, the peptide is cleaved from the resin and deprotected using trifluoroacetic acid (TFA). Crude peptides undergo purification via preparative HPLC, achieving target purity levels. This process minimizes side reactions and ensures batch-to-batch consistency.

Purification and Testing

Post-synthesis, BPC-157 peptide is purified using reverse-phase HPLC, which separates the target peptide from impurities based on hydrophobicity. Each batch is tested for purity, identity, and content using HPLC, MS, and amino acid analysis. Third-party laboratories verify these results, providing certificates of analysis (CoA) that detail purity percentages, residual solvent levels, and endotoxin limits.

Certification and Compliance

• Certificate of Analysis (CoA): Includes HPLC purity, MS confirmation, and peptide content
• Endotoxin Testing: ≤1 EU/mg for cosmetic-grade; ≤0.5 EU/mg for lab-grade
• Residual Solvent Analysis: Meets ICH Q3C guidelines for Class 2 solvents

• Batch Traceability: Unique lot numbers for full supply chain transparency

Commercial Application Scenarios

BPC-157 peptide is utilized across multiple B2B sectors, including cosmetic formulation, laboratory research, and bulk wholesale distribution. Each application requires specific purity grades and handling protocols to achieve desired outcomes.

Cosmetic Formulation

In cosmetic products, BPC-157 peptide is incorporated into serums, creams, and masks at concentrations of 0.1% to 1%. Its high solubility allows for easy integration into water-based formulations. Cosmetic manufacturers prioritize purity ≥99% to avoid skin irritation and ensure product stability. The peptide is often combined with hyaluronic acid or antioxidants to enhance formulation efficacy.

Lab Research

Research laboratories use BPC-157 peptide in cell culture studies and animal models to investigate cellular mechanisms. Purity ≥98% is standard for in vitro experiments, while in vivo studies may require endotoxin-free grades. Researchers rely on CoA documentation to validate peptide identity and avoid experimental variability.

Bulk Wholesale Usage

Bulk buyers, such as peptide distributors and contract manufacturers, source BPC-157 peptide in quantities ranging from 10 grams to 1 kilogram. They require consistent batch quality, competitive pricing, and reliable supply chains. Wholesale agreements often include custom packaging, such as vacuum-sealed vials or bulk drums, to preserve peptide integrity during shipping.
