How We Verify Semaglutide Purity
Because Semaglutide is often sold as a research chemical, it is not subject to FDA manufacturing oversight. This means the market is flooded with under-dosed, impure, or completely fake products. We protect researchers by demanding transparency.
For a vendor to be listed on this page, they must provide a valid Certificate of Analysis (COA) from an independent, US-based analytical laboratory (like MZ Biolabs or Janoshik). This COA must prove that the Semaglutide batch meets or exceeds 98% purity via High-Performance Liquid Chromatography (HPLC).
Learn how to read and verify a COA yourself.
