Core Molecular Specs & Technical Index
BPC-157 peptide, also known as Body Protection Compound-157, is a synthetic pentadecapeptide composed of 15 amino acids. For B2B buyers in cosmetic formulation and laboratory research, understanding the core molecular specifications is the first step toward reliable sourcing. The peptide sequence is Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val, with a molecular weight of approximately 1419.5 Da. High-purity BPC-157 peptide is defined by a minimum of 98% purity as verified by HPLC analysis, with residual solvents and heavy metals strictly controlled below ICH Q3C and USP <232> limits. Solubility in water exceeds 10 mg/mL at room temperature, and lyophilized powder should be stored at -20°C in airtight, light-resistant vials to maintain stability for up to 24 months. Key technical indices include peptide content (N% based), acetate or TFA counterion content, endotoxin levels below 0.5 EU/mg, and microbial limits compliant with USP <61> and <62>.
- Purity threshold: ≥98% by HPLC area normalization, with single impurity ≤0.5%
- Molecular weight confirmation: Mass spectrometry (ESI-MS or MALDI-TOF) within ±0.5 Da of theoretical value
- Counterion content: Acetate form preferred for cosmetic applications; TFA content ≤1% for lab research
- Solubility profile: ≥10 mg/mL in sterile water for injection; ≥20 mg/mL in PBS (pH 7.4)
- Stability data: Lyophilized powder stable for 24 months at -20°C; reconstituted solution stable for 7 days at 2-8°C
Industry data from the Peptide Therapeutics Foundation indicates that over 85% of peptide-related quality failures in B2B transactions stem from purity below 95% or incorrect counterion profiles. Certified manufacturing with full analytical documentation reduces sourcing risk by 70%.
Manufacturing & Quality Control
The production of high-grade BPC-157 peptide follows a stringent solid-phase peptide synthesis (SPPS) protocol using Fmoc chemistry. Each batch undergoes a multi-step purification process including preparative reverse-phase HPLC with a C18 column and gradient elution using acetonitrile/water with 0.1% TFA. After purification, the peptide is lyophilized under controlled conditions to preserve structural integrity. Quality control includes a comprehensive panel of tests: HPLC for purity, ESI-MS for molecular weight confirmation, amino acid analysis for composition verification, and Karl Fischer titration for residual moisture (target ≤3%). Third-party testing by an ISO 17025 accredited laboratory is mandatory for each batch before release. Certifications commonly required by B2B buyers include Certificate of Analysis (CoA), Certificate of Origin, and Material Safety Data Sheet (MSDS). For cosmetic raw material applications, additional documentation such as INCI name listing and stability study reports are provided.
- Synthesis method: Fmoc SPPS with HBTU/HOBt activation, 0.1-1.0 mmol scale
- Purification: Preparative HPLC, C18 column, 10-40% acetonitrile gradient over 60 minutes
- Analytical testing: HPLC, ESI-MS, amino acid analysis, moisture content, endotoxin, microbial limits
- Documentation: CoA with batch number, retention time, purity percentage, and impurity profile
- Certification: ISO 9001:2015 for manufacturing; ISO 17025 for third-party testing lab
Commercial Application Scenarios
BPC-157 peptide serves as a high-value raw material in multiple commercial channels. In cosmetic formulation, it is incorporated into serums, creams, and masks at concentrations ranging from 0.1% to 1% for its skin-conditioning properties. Formulators value its stability in aqueous systems and compatibility with common preservatives and emulsifiers. In laboratory research, BPC-157 peptide is used as a reference standard for cell culture studies and animal model investigations, requiring consistent batch-to-batch purity and activity. Bulk wholesale buyers, including peptide distributors and contract manufacturing organizations (CMOs), source BPC-157 peptide in quantities from 1 gram to 10 kilograms for downstream processing or repackaging. Each application scenario demands specific documentation: cosmetic formulators require INCI compliance and stability data, researchers need purity certificates and MSDS, while wholesalers expect GMP compliance and chain-of-custody records.
- Cosmetic formulation: 0.1-1% concentration, pH 5.0-7.0, compatible with hyaluronic acid and glycerin
- Lab research: 1-100 mg vials, lyophilized, reconstituted in sterile water or PBS
- Bulk wholesale: 1g, 5g, 10g, 100g, 1kg packaging with tamper-evident seals
- Custom synthesis: Modified sequences, labeled variants (e.g., biotinylated BPC-157)

Bulk Purchase Selection Guide
When sourcing BPC-157 peptide for commercial applications, B2B buyers must navigate common pitfalls to ensure quality and compliance. The first pitfall is relying solely on price as a decision factor; low-cost peptides often have purity below 95% or incorrect counterion profiles that compromise formulation stability. The second pitfall is neglecting third-party testing verification; always request the CoA from an ISO 17025 accredited lab and cross-check the HPLC chromatogram for impurity peaks. The third pitfall is overlooking storage and handling requirements; BPC-157 peptide is hygroscopic and sensitive to light, so packaging must include desiccant and UV-protective vials. A buyer checklist includes: verify supplier GMP certification, request batch-specific CoA, confirm counterion type and content, check endotoxin levels for intended application, and review stability data under recommended storage conditions. For bulk orders exceeding 100 grams, request a sample batch for in-house testing before full commitment.
- Pitfall 1: Price-based selection without purity verification
- Pitfall 2: Ignoring third-party testing documentation
- Pitfall 3: Inadequate storage and handling protocols
- Checklist: GMP certification, batch CoA, counterion profile, endotoxin level, stability data
