Paperwork check

Does the seller show their working?

Most sellers publish something they call a certificate. Paste the site you bought from and we will check whether that document is worth anything — whether it covers your lot, names a lab, and whether that lab confirms it.

Queue a site

Paste the page you bought from. A storefront, a listing, a group-order post — anything with a link.

What the check covers

Five questions, all answerable from documents.

Published at all
Whether any certificate is reachable from the product page, or only promised in the copy.
Matched to your lot
Whether the document names the batch you were sent, or is one generic file served for every order.
Lab named
Whether the issuing lab is identified. An unsigned, unattributed PDF is a design asset, not a result.
Lab reachable
Whether that lab exists, does the assay it is credited with, and confirms the report is theirs.
Scope stated
Which assays the document actually covers. A purity-only COA says nothing about sterility or dose.

What it does not tell you

Nothing about what is in the vial. A seller’s certificate is the document most worth forging in this market, so reading one cannot grade a peptide — it can only tell you whether the seller is showing their working. A site can pass all five checks and still ship a bad batch, and the only way to know is to have the vial assayed.
