Core Molecular Specs & Technical Index
BPC 157, or Body Protection Compound 157, is a synthetic pentadecapeptide composed of 15 amino acids. It is derived from a protein found in human gastric juice and is manufactured for laboratory research and cosmetic formulation purposes. For B2B buyers—including cosmetic chemists, research laboratories, and bulk raw material distributors—understanding the precise technical specifications of this peptide is essential for quality assurance and application success.
The peptide is characterized by its molecular formula C62H98N16O22 and a molecular weight of approximately 1419.5 g/mol. It is supplied as a lyophilized (freeze-dried) white powder, ensuring long-term stability and ease of reconstitution. Key technical indices include:
- Purity Level: Standard pharmaceutical-grade BPC 157 is offered at ≥98% purity, verified by High-Performance Liquid Chromatography (HPLC). Premium grades reach ≥99% for advanced research applications.
- Solubility: Highly soluble in sterile water, saline, or phosphate-buffered saline (PBS). For cosmetic formulations, it dissolves readily in aqueous bases without precipitation.
- Storage Conditions: Lyophilized powder must be stored at -20°C or below, protected from light and moisture. Reconstituted solutions should be used within 24-48 hours and stored at 2-8°C.
- Appearance: White to off-white lyophilized powder, free from visible particulates or discoloration.
- Endotoxin Levels: Low endotoxin content (<1 EU/mg) is standard for research-grade material, ensuring minimal interference in biological assays.
Industry data from the Peptide Research Association (2023) indicates that over 85% of bulk peptide buyers prioritize HPLC purity certificates and third-party mass spectrometry verification when sourcing BPC 157. This underscores the critical role of transparent quality documentation in B2B transactions.
Manufacturing & Quality Control
The production of high-purity BPC 157 involves a multi-step process that demands rigorous quality control at every stage. Manufacturers typically employ solid-phase peptide synthesis (SPPS) using Fmoc chemistry, followed by cleavage, purification, and lyophilization. Each batch undergoes comprehensive testing to ensure consistency and compliance with research-grade standards.
Key manufacturing steps include:
- Solid-Phase Synthesis: Automated peptide synthesizers assemble the 15-amino-acid chain on a resin support, with each coupling step monitored for efficiency.
- Cleavage and Deprotection: The peptide is cleaved from the resin using trifluoroacetic acid (TFA), simultaneously removing side-chain protecting groups.
- Purification: Preparative HPLC is used to isolate the target peptide from truncated sequences and impurities, achieving the desired purity threshold.
- Lyophilization: The purified peptide is freeze-dried under vacuum to produce a stable, amorphous powder with low residual moisture.
- Quality Control Testing: Each batch is subjected to HPLC, mass spectrometry (MS), amino acid analysis, and endotoxin testing. Certificates of Analysis (CoA) are provided to buyers.
Certifications that reputable suppliers offer include:
- Certificate of Analysis (CoA) with HPLC chromatogram and purity percentage
- Mass spectrometry (MS) confirmation of molecular weight
- Endotoxin test report (<1 EU/mg)
- Residual solvent analysis (TFA content)
- Stability data under recommended storage conditions
Commercial Application Scenarios
BPC 157 is primarily utilized in two commercial domains: cosmetic formulation and laboratory research. For B2B buyers, understanding these applications helps in selecting the appropriate grade and quantity for their specific needs.
Cosmetic Formulation: In the cosmetic industry, BPC 157 is incorporated into topical serums, creams, and gels designed for skin health and appearance. Its small molecular size allows for potential dermal penetration, making it a sought-after ingredient in anti-aging and skin-recovery products. Formulators typically use concentrations between 0.1% and 1% in aqueous-based systems, often combined with stabilizers like hyaluronic acid or antioxidants. The peptide is valued for its ability to support skin barrier function and promote a healthy complexion.
Laboratory Research: Research laboratories purchase BPC 157 for in vitro and in vivo studies exploring cellular signaling, tissue response, and peptide stability. It is commonly used in cell culture models to investigate fibroblast activity, collagen synthesis, and angiogenesis. Bulk orders for research institutions often require multiple vials of lyophilized powder, with strict documentation for regulatory compliance.
Bulk Wholesale: Distributors and wholesalers source BPC 157 in large quantities (e.g., 1 gram to 100 grams) for resale to smaller labs and cosmetic manufacturers. Bulk buyers prioritize consistent purity across batches, competitive pricing, and reliable supply chains. Many suppliers offer custom packaging, such as pre-weighed aliquots or multi-gram vials, to streamline downstream handling.
