PeptideBenchmark has a disclosed affiliate relationship with Midwest Peptide. This does not change benchmark scores or trust ratings — it only affects outbound links and pricing-board discount modeling where applicable.
Readers who want a single vendor whose entire injectable catalog is covered by independent, portal-verifiable third-party COAs at competitive per-vial pricing.
The GLP products are branded — GLP-3 RT is retatrutide, GLP-2 TZ is tirzepatide — and the KLOW / GLOW recovery blends are mapped to their components for $/mg comparison. Oral capsule products (BPC-157, GHK-Cu, SLU-PP-332, tesofensine) are sold but sit off the injectable-vial board. Unrelated to Midwest Compounds (midwestcompounds.com), which also prints Freedom search codes that start with Midw; the client line on the certificate is the discriminator.
Included because Midwest Peptide pairs an openly priced catalog with product-level ILS Laboratories and Freedom Diagnostics certificates that can be checked independently at the issuing laboratory.
Midwest Peptide publishes product-level certificates from ILS Laboratories and Freedom Diagnostics. The current review covers every in-scope catalog product, with exact provider verification and separate reporting of purity, identity, net content, and any safety panels present on each certificate.
The current review retains 34 distinct certificates across all 30 in-scope catalog products: 21 Freedom Diagnostics reports and 13 ILS Laboratories reports. Each has an exact laboratory verification route. Results and safety panels remain specific to the individual certificate; a reported endotoxin value is not labeled a pass unless the report states that conclusion.
This vendor is one of 131 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.
Midwest Peptide 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 30 products and 34 document/link destinations.
2 named lab signal(s) and 1 certification category signal(s) are currently visible in the reviewed evidence.
Score 10.0 from 10-point benchmark blend.
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 9.39 — the live evidence-first score is 8.18 (-1.21). What changed and why: scoring methodology.
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.
WHAT THIS PAGE IS
- Board-ranked vendor profile with source-linked benchmark inputs
- No Finnrick score currently linked
- Includes Peptide Critic score coverage
- Includes Trustpilot review coverage
- No Pep Review Pro profile currently linked
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.
