## Regulatory disclosure

Compounded semaglutide is dispensed via 503A licensed compounding pharmacies (USP <797>) or 503B FDA-registered outsourcing facilities (cGMP). Compounded semaglutide is **not FDA-approved** and is **not the same as Ozempic, Wegovy, or Rybelsus** — these are the only FDA-approved semaglutide products (Novo Nordisk). Legitimate compounded semaglutide must use semaglutide base only — not salt forms. In April 2026 the FDA announced intent to restrict mass-marketed compounded GLP-1 ingredients. The FDA approved Foundayo (orforglipron, Eli Lilly), the first new-molecule oral GLP-1 receptor agonist for chronic weight management. The only FDA-approved oral semaglutide is Rybelsus (3-14 mg daily, type 2 diabetes only).
