Every production batch is tested by a named independent laboratory, and its certificate is published here. This is the single record that tells you exactly what is in the vial you hold: which molecule, how pure, and what else the analysis found. No unbacked badges, no headline percentages without a trace behind them.
Look up your batch
Each vial is marked with a lot number, printed on the label and encoded in a QR code. The lot number is the key to that batch’s own Certificate of Analysis (CoA), the test report for that specific production run and no other.
There are two ways to reach a certificate:
- Scan the QR code on the vial. It resolves straight to that batch’s CoA. No manual cross-referencing, no guessing which document applies.
- Search the lot number. Read the lot number from the label and look it up in the batch library below. The certificate that matches is the one that carries the same lot number and analysis date.
A certificate belongs to your vial only when three things line up: the product identity, the lot number, and the appearance all match what you received. If any of those disagree, treat the document as belonging to a different batch and contact us.
The batch library populates as batches ship
Certificates are added per batch, as each production run is tested and released. The searchable library therefore grows over time: a newly listed product may show a small number of live certificates at first, with more added as further batches are manufactured and shipped. If your lot number is not yet visible here, scan the vial QR code or send us the lot number and we will point you to the exact certificate.
Live certificates are indexed by lot number below. This library is additive; it fills as batches ship.
Independent verification you can check yourself
A certificate is only as trustworthy as the ability to confirm it independently. Each batch is characterised by a named third-party laboratory, and each certificate carries a verification key issued by that lab. You can take the key to the testing laboratory’s own website and confirm the result there, directly at source, without relying on anything hosted by us.
In other words: we publish the certificate here for convenience, and the laboratory that ran the test lets you verify the same result on its own system. Two independent places, one matching record. That is the point.
What the certificate shows
Each CoA answers two separate questions with two separate methods, then adds the safety panel a serious research setting expects:
- Identity by mass spectrometry: expected mass against observed mass, with the stated salt form named. This is what proves the vial holds the molecule on the label.
- Purity by HPLC, supplied with the printed chromatogram and integration detail, not a bare number.
- Heavy metals screened by ICP-MS against limits.
- Bacterial endotoxin by the LAL method, against a stated limit.
For a full explanation of each gate and the methods behind it, see how we test. To learn how to read one of these documents line by line, including the salt-form and mass-match traps that catch out weaker certificates, see our guide to reading a CoA.
Testing establishes the identity and quality of a research material. It says nothing about, and implies nothing about, any use in or on the body.
