Attest214 tests peptide and small-molecule lots and hosts the resulting record. We draw the sample ourselves. We publish every test performed on the lot, including the ones nobody wants published. The record lives here, on our domain, where the seller cannot reach it.

214 nm — the wavelength at which the peptide bond absorbs, and at which purity is measured.
We have examined certificates whose purity value is passed in the URL. Change the number in the address bar and the page renders a new certificate. Nothing was measured a second time.
When a manufacturer posts its own sample to a laboratory, the manufacturer chooses which unit gets tested. The result is true of that vial and says nothing about the lot you bought.
Laboratories return results to the customer. The customer decides what reaches the public. A page of clean certificates can sit on top of any number of failures you will never see.
A vial can be 99 % pure by HPLC and 65 % peptide by weight. The rest is water, salt and bulking agent. Net peptide content is the number that catches this, and it is the number most often left off.
A purity figure without a wavelength, a column and a gradient cannot be checked or reproduced. Most certificates in this market state none of them.
A result from two years ago is still being used to sell product made last month. Without a lot number binding it, one certificate can cover everything forever.
| Typical market COA | Attest214 record | |
|---|---|---|
| Who chose the sample | The manufacturer, unstated | Stated on every record — witnessed draw, random pull, retail purchase or client-submitted |
| Bound to a production lot | Often "Batch: Unknown" | A record cannot be published without a lot number |
| Incomplete result sets | Rendered as a pass | Rendered as INCOMPLETE, with the missing tests named |
| Selective publication | Invisible | Every record shows tests published of tests performed |
| Method disclosure | Rarely stated | Wavelength, column, gradient and retention time on every chromatographic result |
| Where the record lives | A PDF or image on the seller's site | Served from attest214.com, not editable by the seller |
| Ageing | No expiry | Issue date, age in days and retest date shown |
Peptides. Anything intended for injection additionally requires bacterial endotoxin and sterility.
An officer pulls units at random from your sealed lot, or we buy your product at retail like any customer. You do not choose the vial. That is what makes the record worth something.
Identity, purity, net peptide content, water, counterion, residual solvents, and endotoxin and sterility for injectables. Every method is disclosed on the record.
Print it on the vial or carton. It resolves to a record on our domain that you cannot edit and we will not remove. Customers scan with the product in hand.
