Lab testing
We send samples to Janoshik Analytical, an independent testing lab, and publish the reports here unchanged. Each report shows how much compound the lab measured in the vial and how pure it is, and carries a unique key so you can check it with the lab yourself.

How to verify a report

- Enter the verification key printed at the bottom of the certificate (also listed above).
- The lab shows its own copy of the report. It should match the PDF published here.
How to read a report
- Sample: the product and labelled amount that were sent to the lab.
- Measured content: how many milligrams of the compound the lab found in the vial. A result at or slightly above the labelled amount means the vial is not under-filled.
- Purity: the share of the material that is the target compound. Above 99% is a high result for research peptides.
- Client and manufacturer: the names under which the sample was submitted to the lab.
