A member-gated storefront whose /lab-results pages sit behind a sign-in, while the underlying public document bucket currently retains 71 product-linked certificate origins. 65 resolve through Freedom Diagnostics; the rest, including 2 Vanguard Laboratory documents, stay named-lab or vendor-hosted evidence.
Readers who want per-product COAs that verify independently at the testing lab (Freedom Diagnostics), across a broad research-peptide catalog.
The /lab-results pages require a member sign-in to browse, so a casual visitor cannot page through them — but the certificate PDFs themselves are on a public bucket and Freedom-verifiable, so the evidence is real and independently checkable.
Per-product COAs with Freedom Diagnostics provider verification
Peptide Supply Co gates its Squarespace /lab-results pages behind a member sign-in, but each page embeds a certificate from a public storage bucket. 65 certificate origins carry Freedom Diagnostics accession/search codes that resolve at the provider; the rest, including 2 Vanguard Laboratory reports, remain named-lab or vendor-hosted evidence. Identity and HPLC appear throughout the retained set, net content and endotoxin on most reports, heavy metals on a minority, and sterility on a few. PB shows those panel results certificate by certificate rather than describing the archive as a uniform full-safety panel.
Assayed content is not fill accuracy. Laboratories report net peptide content, and peptides ship as salts, so an honestly filled vial commonly assays below its gross label — a figure under 100% is not evidence of a short vial. These numbers are also not comparable between vendors: they exist only where a laboratory reports net content, so they partly reflect which laboratory a vendor uses.
