What this page can say
The names below are facts about certificates we opened. They are not a ranking of laboratories against one another, and they carry no HPLC purity score. Seller certificate tier is still the ranking on every price page.
The purity and dose gate is written and off. We do not invent pass or fail from missing certificates of analysis.
Deferred: HPLC scores, a lab quality letter, and turning the purity gate on. Those need quality data we are entitled to use. They are not shipped.
How to check a certificate from North American Diagnostics
A certificate on a seller's site is a file the seller uploaded. A certificate this lab's own website shows you is something else. Take the codes printed on the file and type them in here yourself. Do not follow a link or a QR code printed on the file. A fake certificate carries a fake link.
- Find these on the certificate: Test ID from the report, in the form PSP-NNNNNNN or the equivalent for another client; or the batch ID printed on the report.
- Type the laboratory's address into your browser: https://nadiagnostics.com/verify/
- What a real one shows you: The lab results published for that batch, issued as a certificate of analysis. The lab says every certificate is published and permanently linkable by batch number. Anything else, even a page that loads but shows no report, means the certificate has not been confirmed.

- Pricing

- Stated. The lab says it does not sell the products it tests and that its only product is the truth about what is in them. No owner is named; an analysis administration lead signs the certificate. nadiagnostics.com
Report numbers look like this: a test ID built from the client prefix and a seven digit number, for example PSP-0029123, with a client supplied batch ID
Our notes
- The certificate reports three numbers and no specification. There is no acceptance criterion, no pass or fail column and no limit printed against purity, mass identification or mass content. The lab's own copy argues for this, saying it gives clear purity percentages and identity confirmation rather than vague pass or fail hand waving. pspeptides.com
- The unannounced buying programme is unusual in this set. Most laboratories here test only what a customer sends, which means every result on their site was paid for by the party it reflects on. nadiagnostics.com
