We publish the criteria, not just the names

A vendor directory whose standards are hidden is an advertisement. These are the eight checks every listed vendor passes, what evidence satisfies each one, and where our own commercial interests lie.

  • Batch-matched COAs
  • Independent testing
  • Listing cannot be bought
Verification is about the material, not the use. Confirming that a vial contains what its label says tells you nothing about whether the compound is safe, effective or legal to use — and most compounds in this category are not approved for human use in any jurisdiction we track. A perfect COA on an unapproved peptide answers the easy question only.

1 verified vendor

Deliberately short. We would rather list one vendor we have actually checked than twenty we have not.

Conflict of interest

Related party. 18PEPS is Biolivon's own marketplace. This listing is subject to the same criteria as any other vendor and to the same re-verification schedule, and the relationship is disclosed in full on our disclosures page.

Checks

  • Batch-matched COA
    Verified

    COA resolves to the batch identifier printed on the vial.

    Evidence: Sampled three purchased batches; certificate identifiers matched in all three.

  • Independent third-party testing
    Verified

    Laboratory named and not owned or controlled by the vendor.

    Evidence: Laboratory named on the certificate; ownership checked against company records.

  • Mass-spec identity confirmation
    Verified

    Molecular weight confirmation alongside purity.

    Evidence: Mass spectra supplied with each sampled batch.

  • Full chromatograms published
    Verified

    Complete run times and visible baselines.

    Evidence: Uncropped HPLC traces reviewed for the sampled batches.

  • Chain of custody
    Verified

    Documented path from synthesis to dispatch.

    Evidence: Custody documentation supplied and reviewed.

  • Retained samples
    Verified

    Retention samples held for independent re-testing.

    Evidence: Retention policy documented; sample storage confirmed.

  • Accreditation scope
    Verified

    ISO/IEC 17025 scope covering the tests performed.

    Evidence: Accreditation certificate and scope schedule reviewed.

  • No health claims
    Verified

    No therapeutic claims for unapproved compounds.

    Evidence: Full site review at verification date; re-checked at each cycle.

Criteria

The eight checks, and what satisfies each

Identical for every vendor. A vendor's own statement is never evidence — each check has to be satisfied by a document we hold or an action we took.

  1. 01

    Certificate of analysis, per batch

    A COA that names the batch on the vial in front of you — not a specimen document, not a COA for a different lot. We check that the batch identifier on the certificate resolves to a real, purchasable batch.

  2. 02

    Independent third-party testing

    Testing commissioned from a laboratory the vendor does not own or control, with the laboratory named. Manufacturer-run testing is not disqualifying, but it is a weaker form of evidence and we label it as such.

  3. 03

    Identity confirmed by mass spectrometry

    Purity alone answers the easier question. We require mass-spec confirmation that the molecule is what the label says, not merely that the sample is 99% of something.

  4. 04

    Methods and chromatograms published, not just numbers

    Full HPLC chromatograms with visible baselines and complete run times. A cropped trace or a bare purity figure with no method fails this check.

  5. 05

    Chain of custody

    A documented path from synthesis through storage and shipping, including who held the material, under what conditions, and how the sample sent for testing was selected. Vendor-selected samples are noted.

  6. 06

    Retained samples

    The vendor keeps retention samples so an independent party could re-test a disputed batch later. Without retention, no claim about a past batch can ever be checked.

  7. 07

    Named laboratory with a stated accreditation scope

    ISO/IEC 17025 accreditation covering the specific tests performed. 'Accredited laboratory' with no scope named tells you nothing and does not pass.

  8. 08

    Honest labelling and no health claims

    No therapeutic or benefit claims for unapproved compounds anywhere on the vendor's site, and no bundling that implies human use. This is where most vendors in this category fail.

Rules

How a listing works

  • A listing cannot be bought. No vendor pays for placement, ranking or a badge.
  • Every check is evidenced by a document we hold. A vendor's own claim is not evidence.
  • Re-verification runs on a fixed cycle. A vendor that misses it is delisted, not grandfathered.
  • Failed checks are shown, not hidden. A partial or failed check appears on the listing.
  • Our own marketplace is listed as a related party and gets no leniency.
  • Verification covers the material only. It is never a claim that a compound is safe, effective or legal to use.

What this is not

The limits, stated plainly

Not an endorsement of any compound

We verify that a vendor's documentation holds up. Several compounds sold by listed vendors are graded Preclinical or Insufficient in our library, and that grading does not change because a vendor passed.

Not a guarantee of any future batch

Verification samples batches at a point in time. It cannot guarantee the batch you receive next month. Ask for the COA that matches your vial.

Not legal advice about import

Whether you may lawfully import a compound depends on your country. In India a first-time synthetic peptide falls under the new-drug pathway. Check before you order.

Are you a vendor who can pass these?

We are interested in vendors who already publish full chromatograms, name their laboratory, and retain samples. If that is not you yet, the Quality Lab explains what each check is asking for and why.
