Peptidetesting
Signals, not verdicts.

Independent labs test what vendors only promise. Find one. Check their certificates.

Trustworthy analytical labs are hard to find, and lab certificates are forged every day. We list independent laboratories openly, and we will check any COA you upload.

Find an independent lab

Compare independent analytical laboratories: methods, scope, how to order a test as a private buyer, and whether their reports can be verified.

Check a certificate

Got a COA from a vendor? Soon you can upload the PDF or a photo here and get a plain traffic-light signal - no account needed. Checks run asynchronously: you get a pickup code and collect your result minutes later.

Built from public sources, confirmed by the labs where possible. Presence and order cannot be purchased.

How we work, and where our limits are

The uncomfortable answer

The only labs that can serve you are the ones with nothing to lose

The labs best equipped to test your peptide are the ones least able to accept it. Accreditation, certification and liability all bite the moment a private person asks for a result. That is not a scandal. It is how this market is built.

Our checks look at the certificate as a document and at the lab behind it:

Document integrityRequired fields, format and internal consistency of the certificate.

Issuer identityDoes the issuing lab exist, and does the document match how it works?

Chemical plausibilityDo the reported values make sense for the stated substance?

Official verification pathsWhere labs offer online verification, we use it - the strongest signal.

Why we don't publish the full checklist: forged certificates would be optimized to pass it. We keep the specifics private for the same reason banks don't publish their fraud detection rules - it protects you and the honest labs. What we never do: issue badges or seals. If a website shows a "peptidetesting.cc verified" badge, it is not from us.

How our results speak

Consistent Not conclusive Contradictory Not enough data

A check returns a signal about the certificate, never a judgment about a product, a vendor, or a lab. Every result says what it does not mean.

Understand testing before you trust it

Labs are used to business customers. You may be the first private buyer they meet. These pieces translate both directions.

For laboratory operators

For laboratories

A new audience is coming to you: private buyers with legitimate testing needs and little idea how labs work. We make the introduction on your terms.

  • Claim your profile and correct or confirm every fact we list. Confirmation is shown with its source, never sold.
  • Dispute channel: if a certificate signal concerns your lab, you can challenge it directly.
  • Verification API (target state): confirm your reports programmatically and make forging your name pointless.

Is your lab listed?

Claiming is free and always will be. Verification runs over your official domain - no documents, no fees.
