The FDA just voted on BPC-157, TB-500 and 5 other peptides. Here's what actually happened.
On July 23–24, 2026, the FDA's Pharmacy Compounding Advisory Committee (PCAC) voted on whether seven peptides should be added to the Section 503A Bulk Drug Substances List. We break down every vote count, what the committee actually recommended, and — just as important — what a "yes" vote does not mean yet.
How the PCAC voted, peptide by peptide
The committee took each nomination separately, voting on the free-base and acetate forms of each substance. FDA staff had recommended against all seven; the committee's final votes broke from that recommendation on six of them.
What actually happens next
Category 2 removal — April 23, 2026
All seven nominated peptides were removed from the FDA's restricted Category 2 list earlier in 2026, which made them eligible for PCAC review. This step did not legalize compounding on its own.
PCAC review and vote — July 23–24, 2026
The committee voted to recommend six of the seven nominated peptides for the 503A Bulks List. These are advisory recommendations to the FDA, not binding decisions.
FDA review of the recommendation
The FDA is not obligated to follow the committee's vote, though it has historically tended to. The agency will decide whether to move forward with formal rulemaking for each recommended substance.
Notice of proposed rulemaking & public comment
If the FDA proceeds, it publishes a proposed rule in the Federal Register and opens a public comment period before any substance can be finalized onto the 503A Bulks List.
Final rule
Only after a final rule is published would licensed 503A pharmacies gain a clear legal pathway to compound these substances against an individual prescription. Analysts following the docket generally expect this to extend into 2027.

A recommendation is not a rule
PCAC recommendations are advisory. The FDA reviews them and decides independently whether to start the formal rulemaking process required to add any substance to the 503A Bulks List. That process includes a proposed rule, a public comment period, and a final rule — a sequence that realistically runs well into 2027 for the peptides recommended on July 23–24.
For 503A and 503B pharmacies, healthcare providers, and researchers, the practical questions are less about the headline vote and more about the regulatory scaffolding underneath it: which specific indications were reviewed, how free-base and acetate forms are treated separately, and what documentation FDA will expect once (and if) a final rule is published.
Common questions about the PCAC vote
The committee voted on whether seven peptides — BPC-157, KPV, TB-500, MOTS-c, Semax, Epitalon, and emideltide (DSIP) — should be recommended for the Section 503A Bulk Drug Substances List, which governs what licensed compounding pharmacies may prepare against an individual prescription.
No. The committee recommended both for the 503A Bulks List, along with KPV, MOTS-c, Semax, and Epitalon. A recommendation is advisory only — neither substance is an FDA-approved drug, and formal rulemaking still has to happen before compounding could become legal.
Not yet. The FDA still needs to complete a rulemaking process — including a proposed rule and public comment period — before any of the recommended substances are formally added to the 503A Bulks List.
Emideltide, also called DSIP (delta sleep-inducing peptide), was the only one of the seven nominations the committee voted against, on a 6–7 count with one abstention.
