Is this QSC Retatrutide Janoshik report genuine?

Press Verify on Janoshik on this page, or go to verify.janoshik.com/verify and enter the unique key 82D6SQM2GSR2 (task #238816). The page that opens is Janoshik's, not ours, and shows the same numbers.
What purity did Janoshik find for QSC Retatrutide?
+
99.547% by HPLC, with 9.52 mg of Retatrutide found in the vial. The analysis was conducted on 22 October 2026 on sample 1, labelled batch 20261003.
What is the difference between HPLC purity and content?
+
HPLC purity is the share of the main peak in the chromatogram, so it says how much of what is in the vial is the target compound. Content is the mass of the target compound Janoshik found in the vial. Purity does not tell you how much compound there is, and content does not tell you how pure it is, so read both.
Does this report cover every QSC Retatrutide batch?
+
No. It covers the one sample it was run on (sample 1, batch 20261003). We plan to extend Janoshik testing to most of the range and will publish each report here. Batch COAs are listed in the COA library by batch ID, and you can test any batch yourself: send us the report and we return the test fee as account credit.
