A reader guide to Purity Research’s public COA Library: the visible certificate count, product and lot fields, release dates, method labels, and document links. It explains what those records can support and what they cannot establish on their own.
What the public COA Library currently shows
Purity Research’s COA Library displayed 63 certificates across 48 compounds when Peptide Index reviewed it on October 29, 2026. Individual entries can show a product name, lot where stated, reported purity, release date, method label, and one or more linked documents. The count and fields are a dated snapshot of the vendor’s live library, not a promise that every product, strength, or future batch will have the same documentation.
Match the document to the exact record
A useful documentation check begins by matching the product name, strength, lot, and date that the source actually shows. The Purity Library makes some of these fields visible for entries such as BPC-157, G3-R, and TB-500. If a field is absent, a reader should preserve it as not stated rather than borrow an identifier from a different document or product page.
Read method labels within their scope
The library displays method labels including HPLC, MS, Endotoxin, UPLC-UV, and HPLC-UV/VIS on different entries. A method label identifies the analytical context the vendor presents for that document. It should not be rewritten as a universal statement that every attribute, batch, or item in current inventory was tested in the same way.
Document format matters
The library contains linked PDFs and some image-based documentation. A file link is useful for traceability, but a reader should still check the document’s own identifiers, date, and stated method. Peptide Index does not authenticate every document, certify a laboratory, or infer a result for a batch that is not displayed.
How this guide fits the Purity Research record
This guide helps readers navigate the vendor-published documentation that underpins the Purity Research source context. Current VIP15 status, pricing, inventory, shipping, and the Peptide Index score are maintained in their separate records so an older documentation entry is not mistaken for a current commercial or verification claim.
