Corrections

26 Dec 2025: Quenna PMQ
Submitter indicated having swapped vendor identification with sample yauaeu5. This should be Quenna PMQ instead of OUPeptide. Evidence under review, ratings might be updated.
26 Dec 2025: Oupeptide
Submitter indicated having swapped vendor identification with sample u4q3pap. This should be OUPeptide instead of Quenna PMQ. Evidence under review, ratings might be updated.
12 Dec 2025: Diju Peptides Wellness and Co
Two samples of Tirzepatide were erroneously entered as from Diju Peptides Wellness, and have been moved to another vendor.
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 July, 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.
