Certificates of analysis

Lab reports, independently verifiable

Here is every certificate we have published. Each one is the lab's own report, not ours. It shows the batch, test date and purity. Use its verify key on the lab's website to check it yourself. We report purity and net content only; no report prints an identity result. We do not test for endotoxin, sterility, heavy metals or microbes.

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.
