Under the published rule that the newest certificate per product counts (A6), tirzepatide is now scored from it, and because PuriLab's site names no operating company or street address it is not an established laboratory in our directory, so the certificate earns the minimum score.

The company posted three certificates dated 30 October 2026 from Amino Metrics, a laboratory whose independence we could not establish, for tirzepatide, KPV and MOTS-c; all three were confirmed at that laboratory. Where a product has several certificates the newest is scored, so MOTS-c now rests on the Amino Metrics certificate, which scores a flat 2.0, instead of an earlier Freedom Diagnostics certificate.
