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.
