Every vendor in PeptideClear's scored catalog that publicly lists BPC-157, ranked by their Vendor Transparency Score. VTS measures what a researcher can verify before purchasing - third-party testing practices, COA accessibility, batch traceability, and operational disclosure - from publicly available materials only. It is not a rating of product quality, purity, or safety. If you are sourcing this compound, transparency is the variable within your control.

| Ascension Peptides ascensionpeptides.com | Moderate | 76 | Public COA library with named labs (SafeCert Labs, MZ Biolabs); HPLC and MS per batch; batch numbers match vials. Aggressive affiliate pricing model produces sticker prices well above actual checkout cost. |
| Alpha Omega Peptides alphaomegapeptide.com | Moderate | 64 | GMP-certified US manufacturing; COA documentation stated per batch; public product and policy pages present. Testing lab name not prominently disclosed on product pages at time of scoring. |
| Biotech Peptides biotechpeptides.com | Limited | 59 | US synthesis and lyophilization stated; COAs available but accessibility and consistency vary by product. Custom synthesis offered alongside catalog compounds. |
| PureRawz purerawz.co | Limited | 59 | Broad multi-format catalog with COAs stated per batch; some COAs publicly accessible, others inconsistent across the catalog. Wide product range includes SARMs and research chemicals alongside peptides. |
| Blue Sky Peptide blueskypeptide.com | Limited | 55 | Established US vendor operating since the mid-2010s; COA documentation inconsistent across the catalog - some products publicly linked, others not. Policy pages present but COA accessibility is the primary gap. |
| Apex Peptides apex-peptides.com | Limited | 44 | 60+ compound catalog with full GLP-1 and healing ranges; COAs available on request rather than published per batch. Catalog breadth is high; pre-purchase COA access is the limiting factor. |
