— The procedure, step by step

Send a vial in 4 steps.

Step 01

Choose the laboratory

Based on your country (Janoshik in the EU, ChemRx / Colmaric in the US), your budget and the analytical panel you want — purity only, or purity + endotoxins, etc.

Step 02

Create the analysis order

On the chosen lab's website, create a research account, select the test, pay online. You receive the shipping address and a task number to write on the package.

Step 03

Prepare and ship

Lyophilized vial in rigid packaging, with an accompanying form, tracked mail. A non-reconstituted vial travels internationally without issue.

Step 04

Receive the CoA

Within 5–15 business days, a signed Certificate of Analysis with HPLC purity, measured mass and a public verification key. The report can be cross-checked directly on the lab's portal.

— RUO reminder

Verifying is science. Not a use validation.

Having a vial tested is part of quality control for research reagents. The resulting CoA does not in any way validate a veterinary, diagnostic or therapeutic use. Peptinium Labs peptides are reserved for in vitro scientific research, in a strictly professional setting.
