The PEPTIDE-L Wave Reaches HHS: Enforcement Discretion … Not the Finish Line
Well, readers, we finally have an answer. Or at least an interim answer. And, yes, it comes with “guardrails.” After the July 23-24, 2026, Pharmacy Compounding Advisory Committee (PCAC) meeting left compounders asking whether (and when) FDA enforcement discretion would follow the favorable peptide votes, HHS has announced a limited Interim Policy. See our previous posts covering the PCAC meetings (here and here). But keep the champagne on ice: This is conditional enforcement discretion while rulemaking proceeds, not final placement on the Section 503A bulks list. That final rulemaking could take quite a while, if FDA’s 503A bulk substance rulemaking process is any indicator of the Agency’s timeliness to action. After 15 years of waiting and since nomination, only six bulk substances have been moved from FDA’s interim 503A list via the required notice-and-comment rulemaking.
HHS Announces Enforcement Discretion
HHS does not intend to take action against a state-licensed pharmacy, federal facility, or licensed physician compounding with a “covered” peptide bulk drug substance (BDS) when all of the Policy’s specified requirements are met. Appendix A lists the six substances that received the July PCAC’s nod of approval and thus are on FDA’s “Interim Access List”: BPC-157, Epitalon, KPV, MOTS-c, Semax, and TB-500.
The Policy’s Appendix A alone, however, does not tell the whole story. Appendix B specifies peptide identities, including amino acid sequence, chemical structure, molecular weight, and molecular formula, and limits routes of administration:
- BPC-157 acetate: subcutaneous, intramuscular, oral, and topical dosage forms
- TB-500 acetate and MOTS-c acetate: subcutaneous or intramuscular injectable dosage forms
- Epitalon acetate: subcutaneous or intramuscular injectable dosage forms dispensed in intermittent courses
- Semax free base: intranasal use
- KPV acetate: topical and oral dosage forms
Furthermore, the Policy requires that the only drug delivery device that can be co-packaged or contain the compounded drug is an FDA 510(k)-cleared syringe because “[m]ore complex drug delivery devices introduce additional patient risk.”
And the sourcing requirements also matter. The original BDS manufacturer must be FDA-registered (as an FDCA section 510 drug establishment) and comply with FDA’s current good manufacturing practice (CGMP) regulations and other FDCA requirements. In addition, the identity of its physical location must appear on the certificate of analysis (COA) that accompanies the product.
Further, the COA must characterize and identify the substance and include testing consistent with Appendix B, which is more onerous than what compounders currently rely on. And, if the peptide BDS is obtained “through an FDA-registered repacker, relabeler, or reseller,” that entity must have performed and documented appropriate vendor validation of the BDS manufacturer and validation of the manufacturer’s COA.
The Policy also calls for reporting “compounded products, serious adverse events, and product quality issues” to FDA and to states where the products are compounded and sent (if different). It is unclear whether FDA wants a report of “products compounded” generally given a straight reading of the Policy. But serious adverse events and product quality issues are clearly reportable regardless of whether they are considered drug-related; adverse event and quality reports must be reported to FDA’s MedWatch program. Product reporting includes:
- Active ingredient and strength of active ingredient per unit;
- Original manufacturer of the active ingredient, including unique facility identifier
for the manufacturing facility; and
- Dosage form and route of administration, ingredient and strength, original manufacturer and facility identifier, dosage form, and route.
Labeling must explain reporting procedures and state: “This is a compounded drug product. Not for resale.” Products must contain only a single API listed in Appendix A—no peptide cocktails here.
Access Moves Ahead—yet the Evidence Debate Remains
The Policy follows the favorable PCAC votes despite FDA scientists’ concerns about limited clinical safety and efficacy data, against a backdrop of growing experimental peptide demand and a thriving “research use only” (RUO) gray market.
HHS expressly targets that problem: It expects limited compounding under the enumerated safeguards to discourage widespread use of certain RUO peptides supplied by foreign manufacturers and to provide a “more controlled alternative,” advancing “patient choice and freedom while appropriately protecting patient safety.” It also anticipates that public comments may supply additional evidence for the forthcoming rulemaking. None of this makes compounded drugs FDA approved, however.
Interim Means Interim
The Policy lasts until a peptide BDS is addressed in a final rule as included or not included on the 503A bulks list. HHS may revisit the Interim Policy, in whole or in part, if, among other things, a safety signal or product-quality issue arises involving a covered product. A big unknown is whether states will follow HHS’s Interim Policy or make their own path.
The takeaway? This Interim Policy creates a conditional interim pathway, substance by substance and route by route, not a blanket green light for these six drugs. One last question: Where is FDA on this Interim Policy? The Policy makes no mention of FDA’s position or perspective at all and is wholly framed as authored by HHS.
