Is Tirzepatide legal? Research-use status
Tirzepatide is sold in the United States as a research chemical for laboratory use only (RUO). It is not approved by the FDA for human use, is not a dietary supplement, and the vendors listed here sell it exclusively for in-vitro research. Buyers are responsible for compliance with the laws of their jurisdiction. PeptideTech does not sell products and does not provide medical advice.
FDA-approved as Mounjaro (2022) and Zepbound (2023). The research vial is not the approved product.
Tirzepatide storage and handling (research context)
