Readers using the 29 retained price observations as a dated comparison and sourcing current pricing and testing documentation directly.

Watch-out

The audited public markup exposed no detectable third-party testing evidence to evaluate. Catalog pages are now in the public evidence sweep after the researcher-login route migrated to the public catalog, but the retained prices are not a restamped anonymous quote, and price comparability is not evidence of identity or purity. Anyone weighing current pricing or testing should request the relevant documentation directly and judge it on its own terms.

Included for its retained pricing record. PeptideBenchmark previously captured 29 directly comparable rows from Strand Bio’s public price list; those accepted rows remain as a dated comparison because PeptideBenchmark has not restamped them as a new anonymous quote. The September 7 public-markup audit detected no Strand Bio testing evidence on 83 reachable research, compliance, and catalog pages after the researcher-login route migrated to the public catalog, while otherwise unlabelled raster image pixels remain outside that claim.

PeptideBenchmark retains 29 formerly public catalog records, each with one vial size and one accepted price, so the dated range still normalizes to $/mg without a deferral. Catalog HTML is now publicly reachable after the researcher-login route migrated to the public catalog; PeptideBenchmark has not restamped those August 15 rows as a new anonymous quote. On September 7, PeptideBenchmark checked 83 publicly reachable research, compliance, and catalog pages, fourteen exact certificate-route 404s, and 1 exact authentication gate reached from public links: the partner feed returned its reviewed 401 approved-researcher response after the researcher-login route migrated to the public catalog. It found no certificate, purity figure, batch identifier, laboratory name, or verification code in the audited public markup. Otherwise unlabelled image pixels were not inspected.

The bounded September 7 audit found no certificates of analysis, purity results, batch identifiers, laboratory names, or verification codes in Strand Bio’s public research, compliance, and catalog markup. PeptideBenchmark checked 83 reachable pages and fourteen conventional certificate routes; none served a public PDF document. Of 1 exact authentication gate reached from public links, the partner feed returned its reviewed 401 approved-researcher response after the researcher-login route migrated to the public catalog. Otherwise unlabelled image pixels are outside this finding. Detectable testing language on public pages appeared only in reviewed comparison or policy context.

PB Curated Assessment is a PeptideBenchmark-authored rubric built from the trust and transparency review layer. It is separate from the source-derived benchmark score.

Early curated case

Strand Bio is curated because it matters to the coverage set, but the current public evidence layer is still early or incomplete.

Evidence access
Thin or unresolved

The current public trust surface is still thin or unresolved.

Verification structure
Not established yet

We do not yet have enough verification structure to treat this as a strong transparency case.

Evidence depth
Unclear

Current review has not yet established broad product-level evidence depth.

Lab context
Little named-lab context

The current evidence layer is still thin on clearly named outside-lab context.

How to read this benchmark

This profile summarizes public benchmark data synced from Finnrick and, when available, Peptide Critic. Finnrick contributes a 10-point average from its vendor table, while Peptide Critic contributes a 5-star rating that we normalize to a 10-point scale before ranking consensus entries.

A high score can be directionally useful, but it is not a substitute for current COAs, identity testing, chain-of-custody details, or your own due diligence. We are intentionally separating source aggregation from first-party editorial claims.

Scores combine PB trust evidence with external signals from Finnrick, Peptide Critic, Trustpilot, and Pep Review Pro when available.
