About Janoshik

An independent analytical lab based in Prague, Czech Republic (Janoshik s.r.o.). Each report carries a task number and a unique verification key.

Accreditation: No accreditation is printed on these reports, and we found no published ISO/IEC 17025 accreditation for the lab (checked Oct 7, 2026).

Tests: On the reports here: HPLC purity and the measured content per vial. Other tests appear only when they're listed under Results.

How to verify: Go to janoshik.com/verify and enter the unique key printed on the report (the report's QR code links there too). Janoshik blocks automated checks, so we haven't matched these records ourselves.
