Quality you can verify

Trust in research materials comes from documentation, not claims. Here is what stands behind every vial.

Independent testing

Each batch is analyzed by a third-party lab using HPLC and mass spectrometry to confirm identity and purity.

Published COAs

The Certificate of Analysis for every lot is available on the product page — purity, method, and batch number.

Batch traceability

Every order is tied to a specific batch/lot, so you always know exactly what you received.

Frequently asked

What does “research use only” mean?

All products are supplied strictly for in-vitro laboratory research and development. They are not drugs or supplements and are not for human or animal consumption.

Do you provide a Certificate of Analysis?

Yes. Every product batch is tested by an independent third-party lab, and the COA (purity, method, batch/lot) is available on each product page.

How are the peptides supplied?

As lyophilized (freeze-dried) powder in sealed vials. Storage and handling guidance is provided for laboratory use.

Who can purchase?

You must be at least 21 years old and a qualified researcher, and you must affirm the research-use terms at checkout.
