Checked 24 Oct 2026

On July 23-24, 2026 the FDA Pharmacy Compounding Advisory Committee (PCAC) voted on the first seven of the 12 peptides that FDA had removed from Category 2 in April after their nominations were withdrawn. The committee recommended six for inclusion on the Section 503A Bulks List — BPC-157, KPV, TB-500, MOTS-c, Semax, and Epitalon — and voted against one, Emideltide (DSIP). FDA staff scientists had recommended against all seven before the vote. A recommendation is advisory, not a rule: nothing at the pharmacy counter has changed for any of these compounds. FDA says it will host a second PCAC meeting on the remaining five peptides before the end of February 2027 (FDA).

Vote Results

FDA’s questions document lists 14 votes, one on each compound’s free base and one on its acetate, and holds no tally (FDA, questions); FDA’s meeting page posts no vote record (FDA, meeting page). The counts on this page are the ones the news reports gave, one count per compound, each with its source: Reuters for six (July 23; July 24, Semax; July 24, emideltide) and STAT for Epitalon, 7–4 (July 24), which Reuters gave no count for. None of them says whether its count was the vote on the free base, the acetate or both.

Three legal events, not one

"Recommended" is not the same as "legal to compound." Three separate legal events sit between the July 2026 vote and legal 503A compounding — only one of them has happened.

Already done (April 2026): Category 2 removal. FDA posted notice on April 15, 2026 that the 12 peptides would be removed from Category 2 after seven calendar days, and the removal took effect April 22. FDA's stated reason: the nominations were withdrawn by the nominators. The same notice pointed to FDA's announced plan to take each peptide to the PCAC. The removal happened months before the vote and is not itself a change in what pharmacies can compound.

  1. PCAC vote — July 23-24, 2026

    The advisory committee reviewed FDA's scientific briefing, heard from the public, and voted. The vote is advisory. It is not a rule, not a law, and not binding on FDA. Committee members can — and here did — vote against their own agency's staff position on six of the seven compounds.

  2. FDA agency decision — no announced date

    FDA now weighs the committee record, its own scientific review, and public comments received during the docket period, then decides whether to move forward with a rulemaking. Still not a rule. Still not law. FDA has not published a timeline for this decision.

  3. Notice-and-comment rulemaking — no announced date

    If FDA proceeds, it publishes a proposed rule, opens a formal public comment period, considers comments, and publishes a final rule with an effective date. Only when that final rule takes effect does a compound become legally compoundable from bulk drug substance under 503A. This step has not begun for any of the seven July 2026 compounds.

Until the final step completes, nothing at any 503A compounding pharmacy has changed for any of these peptides. FDA is not bound by the committee's recommendation.

What Happens Next

FDA rulemaking on the seven July compounds: no deadline announced. FDA will review the committee record and public comments. If FDA moves forward, expect a proposed rule notice in the Federal Register, followed by a comment period (typically 60–90 days), followed at some later date by a final rule.

Second PCAC meeting — before end of February 2027 (exact date TBD): five additional peptides are on the agenda (FDA).
