FDA 503B GLP-1 Comment Window Closes in 11 Days (June 29); PCAC Oral-Presentation Requests Close in 12 Days (June 30)

The two near-term peptide regulatory deadlines moved into the single-digit-week window on June 18. The FDA's April 30 proposed rule to permanently exclude semaglutide, tirzepatide, and liraglutide from the 503B bulks list closes its 60-day comment window on June 29, after which the agency will weigh comments and issue final rulemaking; once final, the rule blocks 503B outsourcing facilities from bulk-compounding the molecules even under future shortage designation. Separately, requests to make oral presentations at the July 23-24 PCAC peptide-compounding advisory committee close June 30; the committee will weigh BPC-157, KPV, TB-500, MOTs-c, DSIP (Emideltide), Semax, and Epitalon for 503A bulk-substances-list inclusion. Written PCAC comments remain open through July 9.

FDA 503B GLP-1 Comment Window Two Weeks From Closure: June 29 Deadline Will End Large-Scale Compounding of Semaglutide, Tirzepatide, and Liraglutide

The FDA's April 30 proposed rule to permanently exclude semaglutide, tirzepatide, and liraglutide from the 503B bulks list enters its final two weeks of public comment on June 15. The 60-day comment window closes June 29, after which the agency will weigh comments and issue final rulemaking. Once finalized, the rule will prohibit 503B outsourcing facilities from bulk-compounding these GLP-1 molecules under any circumstance, including future shortage designation. The 503A pathway through licensed pharmacies remains intact ahead of the July 23-24 PCAC peptide-compounding advisory meeting, but the trajectory for large-scale GLP-1 compounding is fixed. Telehealth platforms (Hims & Hers, LifeMD, others) had already migrated to branded supply via Novo and Lilly partnerships since Q1 2026.
