Peptide COA testing and verification
A certificate of analysis is the document the whole peptide market runs on, and it is the most forgeable artefact in it. Hand a competent forger a PDF and they can change the laboratory name and the purity figure while keeping an accredited lab's letterhead intact.
Which makes verification the part that matters. Not reading the certificate more carefully, but confirming with the laboratory that issued it that the report exists and says what your copy says.
Who is in this table. Only the laboratories running a public certificate lookup that a stranger can use. Roughly half this directory has none, and those are discussed below rather than listed here: a table of places to verify a certificate should not contain places you cannot.

Every figure is read from the laboratory's own published information and links through to the full record. Prices are quoted in the currency each laboratory uses and are never converted.
The identifying fields come before the numbers
A certificate must name the laboratory, carry a laboratory-issued report identifier, name the product, state the batch or lot it describes, and give the date of analysis and the method used. Read those first.
A document reporting 99% purity that names no laboratory, no report number and no lot has established nothing at all. There is no number on it worth reading, because there is no way to tie any of it to anything.
Four things no certificate can tell you
That the vial in your hand belongs to the batch described. That link is an administrative claim, not an analytical result, and nothing on the document can establish it.
Anything the method could not detect. A purity-by-HPLC figure is silent on water content, residual solvents, salt counter-ions and endotoxin unless those tests are separately named.
Whether the lot is uniform. One tested vial says nothing about the rest, which is what variance testing exists to answer.
Its own authenticity. A certificate is a document, and documents are forgeable. Only the issuing laboratory can confirm it.
Half these labs have no public lookup, and some links go nowhere
Fewer than half the laboratories in this directory run a portal that lets a stranger confirm a certificate. When we requested every verification link we had recorded, in September 2026, five of fourteen failed: two were outright 404s, one pointed at a bare homepage when a real form existed elsewhere on the site, one pointed at the laboratory's catalogue, and one pointed at an ordering portal.
That last one is worth dwelling on. Every path on that host returns the same empty page, so the wrong link answered with an HTTP 200 and looked perfectly healthy. Nothing short of opening it would have caught it.
The ones that were repairable were repaired and the rest were removed, because a verify button that verifies nothing is worse than no button at all. The table above is the result.
Common questions
How do I verify a peptide COA is real?
Use the issuing laboratory's own lookup portal with the report identifier printed on the certificate. If the laboratory runs no public lookup, contact it directly with the report number and the laboratory name. Never verify a certificate through the vendor who gave it to you.
What should a peptide certificate of analysis contain?
The laboratory's name, a laboratory-issued report identifier, the product name, the batch or lot it describes, the date of analysis, the method used, and the result. Missing any of the identifying fields makes the result unverifiable regardless of what it says.
Can a certificate of analysis be faked?
Easily. It is a PDF. Batch numbers are also recycled across shipments, so even a genuine certificate can be attached to a vial it never described. A public lookup at the issuing laboratory is the only defence that does not require trusting the seller.
