Testing
We take purity testing very seriously because your trust is our top priority. All of our peptides undergo rigorous third-party purity testing conducted by Janoshik Analytics, a leading independent lab in the industry.
To ensure the most accurate and up-to-date information, no Certificate of Analysis (COA) is older than three months.

You can independently verify our test results directly through Janoshik’s official verification portal:
