Frequently asked questions.
Who tests your products?
Our batches are tested by independent third-party laboratories, currently Janoshik Analytical and ILS Laboratories. We do not test our own products in-house for the published reports.
How can I verify a certificate?
Each Janoshik certificate carries a task number and a unique verification key. Enter the key at janoshik.com/verify to see the original report on the lab's own website. ILS certificates include a QR code that links to the lab's record.
What does "purity" mean on a report?
Purity is measured by HPLC and shows how much of the sample is the target peptide versus impurities. Measured content (in mg) is the actual amount of peptide found in the vial.
