Built for scientists.

Ziri Labs is a US-based research peptide supplier founded on a simple idea: laboratories deserve compounds they can trust, from a partner who publishes their standards.

Every peptide in our catalog is synthesized in the United States, purified to greater than 99%, and independently verified by mass spectrometry and HPLC before it leaves the facility.

Our catalog is intentionally focused. We stock the compounds that serious research programs actually use, and we support them with certificates of analysis, responsive technical support, and bulk pricing for institutional buyers.

Trusted quality. Advanced research. Laboratory excellence.
