Each criterion below is something you can check yourself; evidence lines carry the date we read them.
| Criterion | Evidence |
|---|
| ✔ | Names its testing laboratory
The lab is identified by name on the vendor's site; you can look it up and contact it. | North American Diagnostics named; lab operates nadiagnostics.com with a batch-lookup portal |
| ✔ | Certificates verifiable at the lab, not just the vendor
COAs are hosted on the testing lab's own system or carry a lab-side lookup code. | Certificates carry lab test IDs (e.g. PSP-0028020) checkable via the lab's lookup portal (portal requires JavaScript; PDFs vendor-hosted) |
| ✔ | Batch-specific COAs matched to lots
Certificates carry lot numbers that match shipped vials, not one generic PDF. | Test ID / batch ID on each certificate; buyers told to match vial lot to certificate |
| ✔ | Publishes measured net content vs label
COAs state measured milligrams against the labelled amount, not purity % alone. | Measured mass vs label published (5.03mg measured vs 5mg label on BPC-157 example) |
| ✔ | COAs and pricing viewable without an account
Open the COA library and catalog logged out. | Downloadable PDFs on every product page and public pricing without an account |
| ✔ | Independent review base (50+ on an external platform)
Check the vendor on Trustpilot or an equivalent platform the vendor cannot edit. | 4.1 / 174 on Trustpilot (verified 5 Sep 2026) |
| ✘ | No contradictions among its own claims
Compare testing/lab statements across the vendor's own pages. | Not awarded |
| ✔ | Vial sizes stated with prices
Catalog or product pages show milligrams next to every price. | Sizes stated with prices across the full GLP range |
| ✘ | Publishes a legal entity and street address
The company's registered name (LLC, Inc., s.r.o. …) and a street address appear on the vendor's own Contact, About or Terms pages — not only a brand name, a city, or hidden page markup. | Not awarded |
| ✘ | No misleading trust signals or buyer-protection workarounds
Compare any on-site review score or badge with the independent platform; check whether the vendor only takes, or pushes you toward, payment rails you cannot dispute; check FDA and BBB records. Awarded unless one of these is on record. | Not awarded |
The record, in one place
| Independent rating | 4.1 (174 reviews) |
| Testing laboratory | North American Diagnostics |
| Certificates | Names North American Diagnostics; certificates carry lab test IDs, are downloadable on every product page without an account, and publish measured mass against label (5.03mg vs 5mg on the example). Widest GLP range in this batch with sized pricing. Legal entity disclosed: ProSupply Services LLC. |
| Caveat | Lowest Trustpilot average of the batch (4.1), and the vendor's own blog claims a '5-star Trustpilot rating from thousands of customers' that the live record does not support. No street address — 'New Jersey-based' only. Certificate PDFs are vendor-hosted; the lab's lookup portal needs JavaScript. |

Check it yourself in ten minutes
Open the vendor's certificate library logged out and confirm the lot number on a live product matches a certificate. Look the laboratory up by name and, where a lookup code exists, verify the report on the lab's own site. Read the independent review record on a platform the vendor cannot edit. Find the legal entity and street address on the vendor's own Contact or Terms page. If any of those fail, treat the missing item as unverified — not as disproven.
