Quality and CoA

Every batch comes with its own certificate of analysis. Not a generic warehouse certificate, but a test per production batch.

What a CoA shows

A certificate of analysis shows the identity and purity of a specific production batch, supported by HPLC and mass spectrometry. Not an assumption, but measured data.

Our process: from source to batch

We work with fixed, vetted sources. Every production batch is tested and documented before release. The result is tied to the batch number on your vial, so certificate and product always belong together.

HPLC and mass spectrometry

HPLC separates the components and measures purity as a percentage. Mass spectrometry confirms identity via the exact molecular weight. Together they show the substance is what it should be, and how pure.

How to read a CoA

You will find the batch number, the identity, the purity and the test date. Check that the batch number matches the one on your vial.

From stock or freshly made

In stock: ordered and paid on a business day before 15:00 (Dutch time), usually shipped the same day. Products we do not stock are made fresh per batch (fresh-batch) and ship within 14 days; we notify you as soon as your batch is ready.

Requesting a CoA

You can request the certificate for your batch via your order, or soon via your account.
