Lab testing & Certificates of Analysis

We manufacture every compound we sell, and we test every batch we manufacture. Independent HPLC analysis confirms identity and purity before any batch is released — and the certificate for your exact batch is available to download below.

How every batch is verified

Tested before it's released

Testing isn't a marketing line for us — it's a release gate. A batch that doesn't meet specification doesn't ship.

1

In-house production

Compounds are synthesised and finished at our GMP-certified facilities in Gloucester and Berlin.

2

Independent HPLC testing

A sample from every batch goes to an independent laboratory for identity and purity analysis by HPLC.

3

COA issued & released

Only batches meeting specification are released. The COA is filed against the batch ID and made available to you.

What we test for

Every certificate confirms

  • ✓ Identity — confirmation that the compound is what it claims to be, matched against a reference standard.
  • ✓ Purity (HPLC) — the percentage purity of the compound, measured by high-performance liquid chromatography.
  • ✓ Batch traceability — each certificate is tied to a unique batch ID so results map to the exact stock you receive.
  • ✓ Test date & laboratory — when the analysis was run and which independent lab performed it.

Testing FAQs

Common questions on our QA

Is your testing done in-house or independently?
Production is in-house, but purity and identity testing is carried out by an independent third-party laboratory. That separation is what makes the result meaningful — the lab verifying the batch isn't the one that made it.
Does the COA match the exact batch I receive?
Yes. Each certificate is tied to a unique batch ID, and that batch ID appears on your product. The COA describes the specific stock you're sent, not a generic sample.
What method do you use to test purity?
Purity is measured by HPLC (high-performance liquid chromatography), the standard method for quantifying the purity of research compounds. Identity is confirmed against a reference standard.
Can I get a COA before I order?
Yes — use the request form above and we'll send the current batch certificate for any compound. Reviewing a COA first is a normal step for wholesale buyers.
Do white label orders come with their own COA?
Yes. Every white label production run is batch-tested and ships with its own certificate, so your customers get the same verification.
