Certificates of analysis

Every tested lot, independently verified

Each report below is Janoshik's, not ours: HPLC identity and assayed purity for one specific batch, with a key you confirm on the lab's own site. We report identity and purity only — not heavy metals, microbial or endotoxin testing.

For laboratory research use only. Not for human consumption.

Published certificates

Checking one yourself

The key is the point

Every report above carries a twelve-character key. Enter it atjanoshik.com/verify and the laboratory shows you its own copy of that certificate. Nothing on this site has to be trusted for that to work.

Identifiers we have not independently confirmed are left off a product page rather than guessed, and a lot that misses spec is rejected rather than relabelled.
