How independent testing works
When a production batch arrives at our Marbella facility, a representative sample is drawn under sealed-chain custody and shipped to an accredited third-party laboratory. The lab runs HPLC to quantify purity and mass spectrometry to confirm the molecule's identity against its theoretical molecular weight. The lab returns a signed PDF report; we publish that file unedited and tie it to the batch code printed on every vial label.
Customer-funded testing. If you want to retest a batch at a lab of your choice, message us with the batch code. We'll coordinate sealed sample shipping and publish the result alongside ours.

Frequently asked questions
Who performs the testing?+
Independent analytical laboratories — primarily Janoshik Analytical — perform HPLC purity and mass-spectrometry identity testing on samples drawn from each production batch.
Can customers fund their own independent retest?+
Yes. We support customer-funded retests at any accredited lab of your choice. Send us the batch number and we will coordinate sealed sample shipping.
Are the PDFs the originals?+
Yes. We publish the lab-issued PDFs unedited — including chromatograms, retention times, and the lab's signature block.
What does a passing result mean?+
≥99% HPLC purity with mass-spec confirmation that the molecule matches the labelled compound. Anything below threshold is rejected and never released.
