Puratek now reads as a real public certifications-archive case with a thinner but meaningful public batch-report surface tied to named outside-lab language.
Readers who want a named-lab batch-report archive whose Freedom Diagnostics certificates are independently verifiable, without needing a login.
Coverage is archive/image-based; most reports carry the Freedom attribution while a few are ILS or unlabeled, so confirm the named lab on the specific batch.
Freedom Diagnostics provider verification archive
Puratek’s public `/coa/` and `/certifications/` archive resolves its batch reports to Freedom Diagnostics (accession-searchable at FreedomDiagnosticsTesting.com), with at least one ILS Laboratories report in the set. That is provider-verifiable public evidence, not just vendor-hosted images.

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.
