01 · Sample pulled

Every production batch has a sample drawn before vials are sealed. The sample never leaves the lyophilisation chamber unblinded.

02 · Independent HPLC

Samples are couriered to a third-party analytical lab that runs reverse-phase HPLC plus mass spectrometry. Their stamp, not ours.

03 · Public certificate

The certificate is published here within 48 hours of receipt. Batch IDs on every vial map 1-to-1 to a downloadable PDF.
