Supplier Verification

Audit Your Supplier

Check whether your current peptide or hormone supplier is registered with FDA as a 503B outsourcing facility — the specific authorization required to legally sell non-patient-specific “office use” compounded product. Results pull directly from FDA’s public registrant records.

Informational only, not legal advice. This tool reports what public FDA records and the supplier’s own website show — it does not determine legality on Sereno GPO’s behalf. Always confirm directly with FDA before making a purchasing decision. We'll ask for your name and email below so we can send you a copy of the report.
