COA Library

Tested every batch.

Every batch we ship has an independently-issued Certificate of Analysis confirming identity (HPLC + MS) and purity. PDFs below are downloadable. Batch numbers print on the vial label so you can match them.

STEP 01

Sample pulled at intake.

Every shipment from a supplier is sealed in our intake bin. Before it touches inventory, a sample is pulled and labeled with the batch number.

STEP 02

Independent lab tests it.

Sample ships to Janoshik Analytical in the EU — the lab that everyone in the research-peptide world trusts because it isn’t owned by any seller. HPLC + MS.

STEP 03

Pass = ship. Fail = burn.

Below 99% purity, or any identity question, the entire batch goes to disposal. We have rotated suppliers over a single failed COA.
