PeptideBenchmark has a disclosed affiliate relationship with Peptide Supply Co. This does not change benchmark scores or trust ratings — it only affects outbound links and pricing-board discount modeling where applicable.
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.
Included as a community-known research vendor whose per-product COAs are third-party Freedom Diagnostics reports with public accession verification.
A member-gated storefront whose /lab-results pages sit behind a sign-in, while the underlying public document bucket currently retains 65 product-linked certificate origins. Sixty-four resolve through Freedom Diagnostics, with one additional Vanguard Laboratory document retained as named-lab evidence.
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. Sixty-four certificate origins carry Freedom Diagnostics accession/search codes that resolve at the provider; one additional Vanguard Laboratory report remains named-lab evidence. Identity and HPLC appear throughout the retained set, net content and endotoxin on most reports, heavy metals on seven, and sterility on one. PB shows those panel results certificate by certificate rather than describing the archive as a uniform full-safety panel.
This vendor is one of 113 names currently included in our manual curated research-vendor layer.
Peptide Supply Co remains the clearest example of a gated vendor whose certificate story is genuinely useful after login while still being materially different from public transparency.
- Current authenticated review found certificate coverage on all 69 covered products, but the structure is closer to one lab-results route per product than to a dense multi-certificate archive.
- The current first pass averages 0 certificate route per covered product, which makes it structurally cleaner but less layered than Polaris or Elite.
- That is why we treat Peptide Supply Co as the model gated case for editorial methodology, not as a public-verification leader.
This is the strongest public transparency pattern on the site. The key signal is that readers can leave the vendor domain and inspect reports or verification pages on an outside provider domain without needing to log in.
- Treat the outside provider route as the strongest part of the evidence, not the vendor marketing copy around it.
- Look for repeated product-level behavior across the catalog, not just one showcase example.
- Do not overread it as proof that every current lot is covered or current unless the linked report trail itself supports that.
This vendor makes the most sense when you compare it to other vendors using a similar transparency model, rather than to every vendor on the board at once.
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.
Peptide Supply Co is currently one of the strongest curated cases on the site because readers can inspect a repeatable public evidence trail without logging in.
Readers can leave the vendor marketing layer and inspect verification publicly.
This is the strongest public pattern because the verification step routes into an outside provider layer.
Current review touched 69 products and 131 document/link destinations.
2 named lab signal(s) and 1 certification category signal(s) are currently visible in the reviewed evidence.
Score 8.7 from pb evidence score.
PB Curated Assessment: Strong. This is our own trust/transparency rubric and is kept separate from the PB score.
Observed from public domain records and the vendor's own site on Aug 27, 2026. Identity facts are shown for context and do not affect scores.
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.

PB score is the number you should read first on this page. It starts with trust evidence, pricing coverage, and third-party review signals from Finnrick, Peptide Critic, Trustpilot, and Pep Review Pro when available. Reviewed transparency evidence contributes a bounded amount — shown as a trust lift for source-benchmarked vendors, and folded into the base score for PB-evidence vendors.
This vendor’s score is evidence-first: verifiable testing evidence forms the backbone, and outside review sources are a bounded adjustment that can warn far more than it can boost. The terms below sum to the displayed score (small rounding aside). Full formula on the scoring methodology page.

METHODOLOGY
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.
