Vendor Verification Standard

Required: all three, checked by us

• RequiredCOAs verifiable at the lab’s own source. Batch-specific certificates whose copy can be retrieved from the testing lab’s own server or verification portal (a lab-hosted file, or a lookup code the lab resolves), with a lot number that matches the product. Reports that exist only as files on the vendor’s own site or storage do not meet this criterion. On our vendors page the “Lab verified at source” field records the first half of this check: whether a lab-hosted copy exists. Matching lot numbers to products is checked when a vendor applies.
• RequiredA payment method with a dispute path. Checkout offers at least one way to pay that lets the buyer dispute the charge if an order never arrives. Checkout limited to crypto, Zelle, CashApp or similar does not meet this criterion.
• RequiredA real legal entity and operating address. The site names the legal entity that sells the products and a physical operating address. A registered-agent address or virtual mailbox on its own does not meet this criterion.

Assessed: the criteria on our vendors page

• AssessedPurity Testing: We prioritize vendors who provide third-party Certificates of Analysis (COAs) with HPLC and mass spectrometry results.
• AssessedReputation: Community feedback from Reddit, forums, and verified purchase reviews.
• AssessedShipping: Speed, discretion, and tracking availability.
• AssessedCustomer Service: Response times and issue resolution.
• AssessedSelection: Range of peptides available and stock consistency.

Every listing also shows, as published facts rather than pass/fail tests, the result of our search of the FDA warning-letter database and the vendor’s public record on Finnrick, an independent lab-testing database, each with the date we checked.

What a passing vendor gets

No vendor has passed yet. This standard is new (version 1, October 27, 2026). The vendors on our vendors page today were listed before it existed and have not been assessed against all three required criteria; each one shows only the checks we have run, with dates.

A “verified” listing on our vendors page and a badge it may show on its own site. The badge links to the vendor’s listing on HighPeptides, so anyone who clicks it sees our current, dated findings rather than a static claim.

How to apply

Email us. There is no form and no fee. Include:

1. Your store URL and the URL of your COA page.
2. Two or three example reports as links on the testing lab’s own server or portal (or lab lookup codes), with the matching product and lot.
3. The name of each lab you test with.
4. The legal entity that sells the products, where it is registered, and your operating address.
5. The payment methods available at checkout.
6. Where you ship, typical delivery times, and how customers reach support.

We check every item ourselves from public pages before replying. Each listing carries the date of our last check; if a later check finds a vendor no longer meets a required criterion, the listing says so, and the badge link leads to that updated finding.

Why these three

A COA is only as good as the lab behind it. A copy on the lab’s own server ties the report to the lab; a file on the seller’s site does not. A payment method you can dispute protects the buyer when an order never arrives. A named entity and operating address mean there is someone accountable for the order. All three can be confirmed by anyone from public pages, which is why we use them. For reading the report itself, see how to read a peptide COA line by line.
