Good to know
Who tested these samples?
+
Janoshik Analytical, an independent third-party laboratory. We submitted the samples; the reports are Janoshik's, and each one can be checked on verify.janoshik.com.
Do these reports cover every batch?
+
No. Each report covers the sample it was run on. Every batch still ships with its own batch COA, and you can test any batch yourself: send us the report and we return the test fee as account credit.
How do I verify a report is genuine?
+
Open the report link on this page, or go to verify.janoshik.com/verify and enter the unique key printed at the bottom of the report.
Reports #238816, #238818, #238820 still list the client as “Anonymous”. We have asked Janoshik to change the header to QSC Peptidology (qscpeptidology.com); the report keys verify at verify.janoshik.com either way.
