GLP-1 API Manufacturers

Manufacturers producing semaglutide, tirzepatide and other GLP-1 class peptides as active pharmaceutical ingredient, for generic developers, CDMOs and formulators. 33 companies listed, 33 with a US Drug Master File on record for at least one GLP-1 molecule.

How to read this:DMF numbers come from the FDA's quarterly list of Drug Master Files. A filed DMF lets a finished-drug applicant reference the manufacturer's data; it is not FDA approval, and its contents are confidential. Patent status for these molecules differs by country, so confirm freedom to operate for your market before sourcing.

What this list does and does not cover

Only manufacturers listed in this directory are shown, and a company appears only when its GLP-1 API offering is confirmed by a DMF filing, a company announcement or its own product pages. "None found" means no DMF for that molecule appeared in the FDA list under the company's legal name; it may still hold a European CEP or supply non-US markets. Research-grade retail sellers are excluded.
