Corrections

29 Jul 2026: ZePeptide

During data capture from photographs of sample **9gsfxvk**, the crimp color was incorrectly recorded as **Golden** instead of **Silver**. Verification against the corresponding Certificate of Analysis (COA) confirmed that the correct crimp color is **Silver**. The record has been updated to reflect the information provided in the COA.

26 Jul 2026: Xingtai Jiachuang Technology

The reported value of 15 mg was inadvertently carried over from a previous Certificate of Analysis (COA) associated with a different sample. This value did not correspond to sample 7f5fe47 and was included in error. The incorrect information has been removed, and the system has been updated to correctly reference the original label claim of 60 mg for this sample.

26 Jul 2026: Bfflink

A data capture error was identified and corrected. The recorded potency was **59.5 mg**, whereas **COA 207430** reports a potency of **95.7 mg**. This discrepancy resulted in an incorrect dosage deviation of **-1%** being recorded instead of the correct value of **+59.5%**. The reported value has been updated to **95.7 mg** in accordance with the COA. As a result of this correction, the calculated score was revised from **10.0** to **6.5**.

20 Apr 2026: Coffee and Peppers

Sample c8x5syc was submitted as 30mg, but physical evidence shipped by the submitter was actually 10mg. This was originally captured as 30mg, which was incorrect. Records corrected on 20 Apr to reflect the correct label claim, which modified the test score from the original 4.2 to 6.0.

26 Mar 2026: Nantong Guangyuan Chemical GYC

Following community reports, we have identified clear signals of large-scale fraud in the name of Nantong Guangyuan Chemical GYC and are retracting all of their tests. The presence on the site ggpeps.net of an obviously fraudulent copy of the Finnrick web site (PeptideMeter.com) shows intent to deceive. Community reports include products not shipped after payment is taken. Finnrick strongly advises against purchasing from this vendor.

25 Mar 2026: Zenith Jove Peptide ZJ

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.

9 Mar 2026: Orbitrex Peptides

Sample nwwrwhu: original COA reported purity of 92.83%. Upon vendor objection, lab investigated and found the automated integration routine picked up noise as peaks and erroneously integrated it. Manual revision led to updated calculations for purity and quantity. The lab issued an updated COA. This sample's test score changed from 5.9 to 9.0, and the Finnrick Rating for Orbitrex Tirzepatide changed from B to A.

6 Feb 2026: Skye Peptides

Two samples of Tirzepatide (4t7h769 and 9872swd) were erroneously attributed to Skye Peptides and removed from the database pending an investigation.

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.
