Frequently Asked Questions

Check us the way you would check any supplier. Every lot is tested by an independent third-party lab, and its certificate of analysis is published on the product page, so you can match the lot number on your vial to its report. Customers review us publicly on Trustpilot, and every order ships from Texas with tracking. See how we test.

Every batch is independently tested by a third-party lab. COAs include purity and content by HPLC, identity confirmation by mass spec, and additional screening such as heavy metals, sterility, and endotoxins when applicable.

COAs are published on tested product pages. Open the product page and use the COA section to view the current batch results. Need a specific COA you don't see? Email support@prismlabs.store.

Peptides are short chains of amino acids — smaller than proteins — that are widely studied in laboratory research for their biological activity and structural properties. All Prism Labs peptides are supplied strictly for in-vitro research and laboratory use only. They are not intended for human consumption.

Prism H2O is a research-grade water for laboratory use — a sterile water mix containing 0.9% benzyl alcohol as a preservative, which inhibits bacterial growth. It's supplied as a standard laboratory research material (often searched as bacteriostatic or BAC water), strictly for research use only. View Prism H2O.
