CURATED VENDOR PROFILE
Simple Peptide
Included because its broad catalog exposes repeatable public COA archive paths across many products.
Same formula for every vendor: verifiable testing evidence forms the backbone; third-party reviews adjust it within a bounded range. How scoring works →

A large, provider-verified COA archive: a public per-batch API surfaces a Freedom Diagnostics search code for nearly every product, and those codes resolve live in Freedom’s public index.
Readers who want provider-verifiable third-party COAs across a broad catalog, confirmable code-by-code against Freedom Diagnostics with no login.
Verification is single-lab (Freedom Diagnostics) and a minority of archive documents remain vendor-hosted without an independent badge.
Freedom Diagnostics provider verification across the archive
Simple Peptide publishes a public COA archive (a WordPress `coa-archive` REST API) that exposes a Freedom Diagnostics search code, purity, net content, and panels for each batch. In the latest audit, 185 of 190 certificate origins across 52 products independently resolved to a real Freedom Diagnostics report in the lab’s public index (a fake code correctly returns not-found), at ~99.5% average purity. The remaining 5 are attributable vendor documents kept without a provider badge.

Representative product pages showing how this catalog exposes report or verification paths. Examples, not proof for every current lot.
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.
4 of this vendor's 103 certificates with indexed embedded images contain reviewed byte-identical chromatograms that also appear in certificate contexts associated with Apex Peptides, Eon Peptides. This is consistent with shared lots, but does not establish a sale or supply-chain direction.
These certificates contain a reviewed byte-identical instrument trace, meaning one analysis was reported in more than one brand context. That supports a shared-lot interpretation, but cannot establish whether either brand sold the lot or who supplied whom. How this is measured →
