Corrections
- 29 Aug 2025: Peptide Sciences
- Peptide Sciences have notified Finnrick that they do not distribute 60mg Tirzepatide. The sample submitted in this quantity, tested 17 Jully, was therefore removed from the site and is no longer part of the Finnrick Rating.
- 17 Apr 2025: NextechLabs
- Lab A test 27 Feb 2025, lab C test 28 Feb 2025, lab B test 30 Mar 2025: updated batch claim quantity, label claim was clear, erroneously listed 10mg.
