Core Molecular Specs & Technical Index
BPC 157 peptide injection is a synthetic pentadecapeptide composed of 15 amino acids, derived from a protective protein found in human gastric juice. For laboratory sourcing and cosmetic raw material procurement, the molecular formula is C62H98N16O22, with a molecular weight of 1419.5 g/mol. The core value for B2B buyers lies in its high-purity, stable lyophilized form, which ensures consistent results in formulation research and bulk manufacturing.
Key technical specifications for professional sourcing include:
- Purity Level: Minimum 98% verified by HPLC (High-Performance Liquid Chromatography), with premium grades reaching 99.5% for advanced research applications.
- Solubility: Fully soluble in sterile water for injection (WFI) at 1-10 mg/mL, with optimal reconstitution at pH 4.0-5.0 for maximum stability.
- Storage Requirements: Lyophilized powder stable for 24 months at -20°C; reconstituted solution stable for 7 days at 2-8°C.
- Appearance: White to off-white lyophilized powder, free from visible particulates or discoloration.
- Endotoxin Levels: Less than 0.5 EU/mg, meeting USP <85> standards for injectable-grade raw materials.
Industry data from the 2023 Peptide Manufacturing Standards Report indicates that 92% of B2B buyers prioritize HPLC purity above 98% when sourcing bpc 157 peptide injection, with a 15% premium for batches exceeding 99% purity due to reduced batch-to-batch variability in cosmetic formulations.
Manufacturing & Quality Control
The production of bpc 157 peptide injection follows a rigorous multi-step process to ensure batch consistency and compliance with laboratory-grade specifications. Solid-phase peptide synthesis (SPPS) is the standard method, using Fmoc chemistry to assemble the 15-amino-acid chain with high precision. Each cycle includes deprotection, coupling, and washing steps, monitored by real-time UV absorbance to track coupling efficiency.
Post-synthesis, the crude peptide undergoes purification via preparative HPLC, achieving baseline separation of target peptide from truncated sequences and deletion impurities. The purified product is then lyophilized under controlled conditions to maintain structural integrity. Quality control includes:
- Third-Party Testing: Independent labs verify purity, identity (MS/MS), and bioactivity (cell-based assays) for each batch.
- Certification Package: Certificate of Analysis (CoA) with HPLC chromatogram, mass spectrometry data, and endotoxin results.
- Stability Studies: Accelerated stability testing at 40°C/75% RH for 6 months to predict shelf life.
- Heavy Metal Analysis: ICP-MS screening for lead, arsenic, cadmium, and mercury below ICH Q3D limits.
- Residual Solvent Testing: GC-MS to ensure acetonitrile and TFA levels below 50 ppm.
Commercial Application Scenarios
BPC 157 peptide injection serves diverse B2B applications across cosmetic formulation, laboratory research, and bulk wholesale markets. In cosmetic raw material sourcing, it is incorporated into advanced serums and topical formulations at concentrations of 0.1-1.0% for its peptide-based properties. Lab research applications include cell culture studies and biochemical assays where consistent peptide quality is critical for reproducible results.
Bulk wholesale buyers, such as contract manufacturing organizations (CMOs), require large quantities (10g-1kg) with strict documentation for regulatory compliance. Typical usage cases include:
- Cosmetic Formulation: Added to anti-aging creams and injectable-grade skincare products, requiring sterile filtration and aseptic filling.
- Lab Research: Used in in vitro studies for peptide-protein interaction analysis, with purity above 99% for accurate binding assays.
- Bulk Wholesale: Supplied in sealed vials with tamper-evident caps, accompanied by batch-specific CoA and MSDS for international shipping.

Bulk Purchase Selection Guide
When sourcing bpc 157 peptide injection for bulk procurement, B2B buyers must navigate common pitfalls to ensure quality and cost-effectiveness. One frequent issue is mislabeled purity, where suppliers claim 98% but deliver batches with 90-95% purity, leading to formulation failures. To avoid this, always request a pre-shipment sample for independent HPLC testing.
Selection standards include verifying the supplier's manufacturing facility is GMP-certified and audited by third-party organizations. Key checklist items for buyers:
- Request Batch-Specific CoA: Ensure each batch has a unique certificate with HPLC chromatogram and mass spec data.
- Check Solubility Reports: Confirm the peptide dissolves completely in WFI without visible aggregates.
- Verify Storage Conditions: Ask for stability data under recommended storage to avoid degradation during transit.
- Evaluate Lead Time: Standard lead time is 10-15 business days for custom orders; expedited options available for urgent needs.
- Review Payment Terms: Use escrow services for first-time orders to protect against non-delivery or quality issues.
