FDA Status
The regulatory classification assigned by the U.S. Food and Drug Administration indicating whether a compound is approved, investigational, or unregulated for human use.
FDA status is one of the most important reference points for any research compound. Approved drugs have completed clinical trials demonstrating safety and efficacy for a specific indication; investigational drugs (IND status) are in active clinical trials; most research peptides lack any FDA designation and are categorized as research chemicals not approved for human use.
The FDA’s recent compounding guidance (notably the 2024 actions around semaglutide) illustrates how rapidly regulatory status can shift for peptide-class compounds. Researchers and practitioners should regularly verify current FDA status, as a compound’s classification can affect its legal availability, manufacturing standards, and institutional use.
