PeptideBenchmark has a disclosed affiliate relationship with Silverstone Labs 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 branded GLP labels mapped on the pricing board plus third-party certificates with report-specific ILS references and lab pages reopened at Kovera or Freedom, alongside deep safety panels — heavy-metals, endotoxin, and sterility — across the core catalog.
Coverage now reaches 30 of 34 catalog products, but 13 gallery certificates cannot currently be checked beyond Silverstone's own site. The 19 ILS report links were read from the certificates but were not freshly reopened during this review; confirm the exact certificate and batch for the SKU you are evaluating.
Included because Silverstone Labs Co has a public storefront with openly visible pricing, branded GLP labels (SLP-2, SLP-3), and product-gallery certificates from three third-party labs — ILS Laboratories, Kovera Labs, and Freedom Diagnostics — that include report-specific references to the issuing labs.
A compact public catalog with branded GLP naming (SLP-2, SLP-3) and core peptide coverage. The current product galleries expose 55 certificate images across 30 of 34 products. Of those, 42 certificates can be checked on issuing-lab pages: 19 ILS certificates print report-specific links that were read from the certificates but not freshly reopened during this review, 7 Kovera codes were reopened successfully at koveralabs.com, and 16 Freedom certificates open at Freedom Diagnostics. Averaged purity runs ~99.7% with unusually broad safety panels — HPLC, identity, heavy-metals, endotoxin, and sterility.
Silverstone publishes 55 distinct certificate images across 30 products. Of those, 42 certificates can be checked on issuing-lab pages: 19 ILS certificates print report-specific links, 7 Kovera certificates were reopened successfully at koveralabs.com, and 16 Freedom certificates open at Freedom Diagnostics. The ILS links were read from the certificates but were not freshly reopened during this review. Thirteen certificates remain available only in Silverstone's galleries, including one Freedom-labeled certificate that could not be corroborated on Freedom Diagnostics' site.
This vendor is one of 113 names currently included in our manual curated research-vendor layer.
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.
Silverstone Labs 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 36 products and 60 document/link destinations.
3 named lab signal(s) and 1 certification category signal(s) are currently visible in the reviewed evidence.
Score 9.2 from pb evidence score.
PB Curated Assessment: Strong. This is our own trust/transparency rubric and is kept separate from the PB score.
Under the formula retired on Aug 28, 2026 this vendor scores 9.20 — the live evidence-first score is 8.19 (-1.01). What changed and why: scoring methodology.

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.

CURRENT LIMITS
- Not an original lab test or editorial review
- Source scales and methodologies differ across sites
- Depends on source site freshness and formatting
These are representative public examples from the vendor testing review queue. They show how product pages in the catalog expose public report or verification paths, but they should still be read as examples rather than proof for every current lot.
In other words: the relationship registry above captures the vendor-to-provider link itself, while the examples below show what that link looks like across real product pages.
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.
