Our peptides maintain a research-grade purity level of >99%. Each batch is rigorously verified using High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS) to ensure precise chemical composition and identity.

A CoA is a document providing the specific test results of a batch. It includes the HPLC chromatogram (purity), Mass Spec (molecular weight confirmation), and appearance. It ensures that the product you receive meets all stated specifications. Every batch CoA is publicly available on our COA library before purchase.

Yes. Every single batch is tested by an independent third-party laboratory before it is made available for purchase. We never self-certify. If a batch does not pass independent testing, it does not get listed — period.

Lyophilized (freeze-dried) peptides should be stored in a cool, dry place away from light. For long-term storage, a refrigerator (2–8°C) or freezer (-20°C) is recommended to maintain maximum stability for up to 24 months.

Yes. All peptides ship in lyophilized (freeze-dried) form for maximum stability and shelf life. They must be reconstituted with bacteriostatic water before use in research applications.

Lyophilized peptides stored refrigerated (2–8°C) or in a freezer (-20°C) have a shelf life of 24+ months. Once reconstituted with bacteriostatic water, the solution should typically be used within 28 days and kept refrigerated.

The volume of BAC water depends on the desired concentration for your research protocol. As a general starting point, 1–2mL of BAC water per vial is common, but this varies by compound and application. We offer BAC water in 3mL and 10mL sizes.
