FDA Proposes Permanent 503B Compounding Ban for Semaglutide, Tirzepatide & Liraglutide
Verified May 8, 2026, Updated July 22, 2026: On April 30, FDA proposed permanently removing semaglutide, tirzepatide, and liraglutide from the 503B outsourcing bulk list, forever, not just during shortage enforcement. Public comment period runs to July 30, 2026. Two days before that deadline, the Pharmacy Compounding Advisory Committee votes on seven peptides nominated for the 503A list (July 23-24), including MOTs-C for obesity. Both decisions land in the same week. 503A patient-specific GLP-1 compounding under medical-necessity remains unaffected.
