Corrections
- 25 Mar 2026
- Sample ef8mddf (Tirzepatide) and ryusy8h (Semaglutide) were reported by the submitter as mixed up, resulting in the incorrect test being run. However, Finnrick believes that such a mistake could have happened at the time of actually using the samples, because the vials are unlabeled, and therefore will not re-run the tests or retract the results, beyond the present note.
Launch with Finnrick
Some of the samples listed on this page were submitted by their vendor, as part of the Launch with Finnrick vendor support program.
The program is designed to help vendors get listed on the Finnrick web site while protecting the integrity of our rating system.
The vendor submitted four samples per product, two of which were tested by Finnrick for identity, purity and quantity according to our usual process. The vials were anonymized before being sent to the testing lab.
