BPC-157 Real vs Fake: Product Comparison
Third-Party Purity Testing HPLC + mass spec showing >98% purity, batch-matched CoA from ISO 17025 lab Generic CoA with no batch number, or no independent testing documentation Batch-specific third-party verification is non-negotiable. Without it, purity claims
This comparison does not assign a generated winner or score.
- Third-Party Purity Testing
- HPLC + mass spec showing >98% purity, batch-matched CoA from ISO 17025 lab
- Generic CoA with no batch number, or no independent testing documentation
- Batch-specific third-party verification is non-negotiable. Without it, purity claims are unverifiable
- Reconstitution Behavior
- Clear, colorless solution within 60 seconds, remains stable for 28+ days refrigerated
- Slow dissolution (>2 minutes), cloudiness, or color shift within 72 hours
- Reconstitution speed and solution clarity are immediate physical indicators of lyophilization quality
- Synthesis Documentation
- Named facility, synthesis method disclosed, batch production date within 6 months
- 'Proprietary source', no facility named, or synthesis date over 12 months old
- Transparency on synthesis origin is the baseline for research-grade peptides. Opacity signals reseller chains
- Endotoxin Testing
- LAL assay results showing <5 EU/mg on batch-specific CoA
- No endotoxin data, or endotoxin testing omitted entirely from documentation
- Endotoxin contamination compromises in vivo research. Suppliers skipping this test cannot guarantee sterility
- Price Positioning
- $45–$85 per 5mg vial from verified suppliers like Real Peptides
- <$30 per 5mg (below synthesis cost) or >$120 (markup without quality justification)
- Pricing below $35 per 5mg is economically impossible for legitimate synthesis. It signals dilution or counterfeit origin
