Janoshik: how to verify a report

Sources checked November 8, 2026.

About

Janoshik advertises chemical analysis of peptides, steroids and pharmaceutical compounds. Its listed tests include peptide screening and growth hormone amount, purity and dimer analysis. It describes digital report delivery by email and through customer accounts.

Website: https://janoshik.com/.

A report describes the sample tested, not every vial or every batch sold by a vendor. This page does not rate labs. Our methodology explains the vendor score.

How to verify a report

  1. Start at https://janoshik.com/ and select Verify from the menu, or scan the QR code on the report.
  2. Have the report and its verification details ready. The homepage describes verification through the Verify tab or QR code. We could not inspect the verification form during this review.
  3. Compare the record returned by the lab with the vendor copy, including the sample description and reported results.
  4. Compare the lab name, report date, product name and lot on the report with the vendor listing and the vial label. A mismatch needs clarification from the vendor.
  5. If details are missing or do not match, contact the lab using independently confirmed contact details and provide the report number.
