Watch, read, check.

Every batch goes to Janoshik Analytical, an independent lab, and its report is published on the Verify page with its batch number and a verification key. Enter the key on Janoshik's own site and you see the lab's copy of the report, not ours — then check the batch number on your carton against it. A new batch whose report is still at the lab is listed there as in progress, never with a placeholder figure. The manufacturer also quality-controls every batch before release.

For every batch whose report is back, yes, and that is the point of them. They're published on the Verify page, each with a key you can check at janoshik.com — no account, no order and no need to ask. The newest compounds (MOTS-C, Tesamorelin, CJC-1295 DAC, GHK-Cu and KPV) went on sale with their first batches still at Janoshik; each one's report goes up on its product page as soon as it's back, and until then the page says so plainly.
