LL-37 5mg

We partner exclusively with ISO 9001:2015 certified facilities. Every batch is independently third-party tested by a U.S.-based laboratory before it is approved for release. Each batch is verified for identity (LC-MS), purity (HPLC-UV), net content, and endotoxin (LAL assay, USP ). Vials are clearly labeled with the compound and its batch (lot) number, and that number matches the batch-specific Certificate of Analysis published for it. Visit our COA library and COA archive to view our public test results.
