Key facts (from the sources below)

  • A recommendation from an FDA advisory committee is not a rule. As of October 25, 2026, we found no FDA final action adding any of the peptides discussed in this post to the 503A bulks list.
  • FDA's briefing document for the July 23–24, 2026 advisory committee meeting says FDA was proposing that none of the seven peptides be included on the 503A bulks list.
  • [S] AJMC reported (July 31, 2026) that the committee recommended six of the seven peptides. This is not confirmed in an FDA document we read.
  • OMB's record shows a received date of 10/14/2026 for an HHS/FDA item titled "Interim Access Policy for Compounding Using Certain Peptides". We have not found its text.
  • FDA's Category 2 page (current as of April 22, 2026) has a section for substances "nominated but withdrawn". That is a list move. It is not a safety clearance or an approval.
  • FDA proposed on April 30, 2026 to exclude semaglutide, tirzepatide and liraglutide from the 503B bulks list. The 503B proposal is not final.
  • FDA's advisory committee page says FDA will host another Pharmacy Compounding Advisory Committee meeting before the end of February 2027, with five substances on the agenda: LL-37, GHK-Cu, dihexa acetate, melanotan II and PEG-MGF. The date is not set.

[S] = reported by a secondary source and not confirmed in a primary document we read.

What this means in plain English

  • A vote is not a rule. FDA's own staff proposed against all seven peptides, and the committee's recommendations are non-binding.
  • Off Category 2 is not "allowed." Leaving Category 2 removes a safety-risk label. It does not add approval.
  • GLP-1 compounding is being narrowed, but the 503B proposal is not final.
  • We have not found the text of the interim policy, so what it would do is unconfirmed.

Updated October 25, 2026. We corrected two items after re-checking primary records. (1) The White House review of the interim peptide policy: the Office of Management and Budget (OMB) record shows it was received on October 14, 2026, not October 15 (October 15 is the date of the AP and CNBC reports). (2) FDA's page for the next advisory committee meeting lists five substances (LL-37, GHK-Cu, dihexa acetate, melanotan II and PEG-MGF), not GHK-Cu alone. We also clarified that Dr. Makary was FDA Commissioner when he made the February statement. See our corrections page.

Peptide rules are changing quickly, and online summaries often mix official actions with rumor. This timeline separates them. For each item we say what an official document shows. Where we only have a news report, we say who reported it and that we could not confirm it in an FDA primary document.

The short version

  • A recommendation from an FDA advisory committee is not a rule. As of October 25, 2026, we found no FDA final action adding any of the peptides discussed below to the 503A bulks list.
  • Two separate FDA tracks are moving in different directions: more openness on some peptides, and tighter limits on compounded GLP-1 drugs.
  • A new FDA peptide policy is under White House review (OMB received it on October 14, 2026). We have not found its text.

Timeline

February 6, 2026: FDA statement on compounded GLP-1s. then-FDA Commissioner Martin Makary (FDA's page lists his term as April 2025 to May 2026) said FDA intends to restrict GLP-1 active ingredients going into non-FDA-approved compounded drugs that are mass-marketed as alternatives to approved drugs. The statement names Hims & Hers and "other compounding pharmacies," and says companies cannot claim compounded products are generic versions of, or the same as, FDA-approved drugs (FDA, Feb. 6, 2026). It states an intent. It is not a final rule.

April 2026: many peptides come off the Category 2 list. FDA's Category 2 page (current as of April 22, 2026) now has a section for substances "nominated but withdrawn," meaning the nominators withdrew them. It includes BPC-157, KPV, TB-500, MOTS-c, CJC-1295 and others (FDA Category 2 page). The law firm Orrick reported that FDA removed 12 peptides from Category 2 and scheduled advisory committee meetings (Orrick). The count of 12 is reported by Orrick, not confirmed in an FDA primary document. The change is a list move. It is not a safety clearance or an approval. Our Category 1 and 2 explainer covers the difference.

April 30, 2026: FDA proposes to exclude three GLP-1 drugs from the 503B list. FDA announced it is proposing to exclude semaglutide, tirzepatide and liraglutide from the 503B bulks list, finding "no clinical need" for outsourcing facilities to compound them from bulk substances (FDA press release). The Federal Register notice (91 FR 23431, published May 1) set a comment deadline of June 30, 2026 (Federal Register). FDA's press release said June 29, so we use the Federal Register date. On June 26, FDA extended comments to July 30, 2026 (91 FR 38719) (Federal Register). FDA said it will consider comments before a final determination. A Federal Register search on October 25 found no final determination.

May 14, 2026: FDA updates its 503A category list. FDA added GHK-Cu (except injectable routes) back to Category 1 after a nominator clarified it withdrew only the injectable route. FDA also said it intends to consult its advisory committee on GHK-Cu before the end of February 2027 (FDA category list, PDF). FDA's page for that meeting now lists five substances on the agenda (see "Next advisory committee" below).

July 23–24, 2026: advisory committee reviews seven peptides. FDA's Pharmacy Compounding Advisory Committee (PCAC) discussed BPC-157, KPV, TB-500, MOTS-c, emideltide, epitalon and semax. FDA's briefing document says FDA was proposing that none of them be included on the 503A bulks list (FDA briefing document). FDA states that advisory committees "make non-binding recommendations" (FDA).

The votes (reported, not confirmed in an FDA document we read). AJMC reported that the committee recommended six of the seven, overriding FDA staff, and rejected emideltide. It reported 8–6 with one abstention for BPC-157, KPV and TB-500, and 7–5 with two abstentions for MOTS-c (AJMC, July 31, 2026). Outlets disagree on the day-two tallies, so we do not repeat them. AJMC also reported that FDA must still decide whether to accept the recommendations and complete proposed and final rulemaking before pharmacies could legally compound the substances.

For Against Abstained (numbers as reported)

  • BPC-157861
  • KPV861
  • TB-500861
  • MOTS-c752

AJMC also reported that the committee rejected emideltide. FDA's briefing document proposed that none of the seven peptides be included on the 503A bulks list.

Outlets disagree on the day-two tallies, so we do not repeat them.

October 14–15, 2026: an "interim access policy" goes to the White House for review. OMB's regulatory review page lists an HHS/FDA item titled "Interim Access Policy for Compounding Using Certain Peptides" (RIN 0910-ZD94, stage: Notice, not economically significant, no legal deadline) with a received date of 10/14/2026 (OMB record). A separate OMB meeting record lists a meeting on this item on October 23, 2026, requested by Hims & Hers Health (OMB meeting record). AP and CNBC reported the plan on October 15 (AP; CNBC). A trade site says its text is not public (Amino Wire). We have not found an FDA or HHS document with the policy text, so what the policy says, and when it might issue, is reported, not confirmed in an FDA primary document.

Next advisory committee (date not set). FDA's advisory committee page says FDA will host a Pharmacy Compounding Advisory Committee meeting before the end of February 2027. The agenda lists five substances being considered for the 503A bulks list: LL-37, GHK-Cu, dihexa acetate, melanotan II and PEG-MGF. The time and location were not yet scheduled, and FDA said a Federal Register notice would follow (FDA, page current as of 04/15/2026). A Federal Register search on October 25 found no such notice.

What it means

What this means in plain words

  1. A vote is not a rule. FDA's own staff proposed against all seven peptides, and the committee's recommendations are non-binding.
  2. Off Category 2 is not "allowed." Category 2 flags significant safety risks. Leaving it removes that label. It does not add approval.
  3. GLP-1 compounding is being narrowed. Both the February statement and the April proposal point that way, but the 503B proposal is not final.
  4. Watch for: the interim policy text, any FDA notice responding to the committee, a final 503B determination, and the date of the next advisory committee meeting, which FDA said it would hold before the end of February 2027 on LL-37, GHK-Cu, dihexa acetate, melanotan II and PEG-MGF.
