Are Peptides Legal in Your State? (2026)
Peptide legality in the US is primarily governed by federal FDA rules — Category 1 (compounding allowed), Category 2 (under review), and FDA-approved status. State pharmacy boards layer additional rules on top. Pick your state for the current regulatory snapshot and the official board reference.
How peptide legality works in the US
Peptide regulation in the US has three primary layers:
- FDA approval — fully approved peptides like semaglutide and tirzepatide can be prescribed in every state.
- FDA bulk-substance categories — Category 1 (compounding allowed under 503A), Category 2 (under review), Category 3 (compounding restricted). Categories are set federally and apply nationwide.
- State pharmacy boards — each state licenses compounding pharmacies, sets sterile-compounding inspection rules, and enforces non-resident pharmacy registration. Some states (Massachusetts, New York, California, Texas, Florida) add stricter inspection and reporting on top of federal rules.
