PCAC July 2026 Results — 6 of 7 Peptides Recommended for Compounding

What is the PCAC hearing and why does it matter?

The Pharmacy Compounding Advisory Committee (PCAC) is an independent panel of scientific and medical experts appointed by the FDA. On July 23 and 24, 2026, this committee met at the FDA's White Oak Campus in Silver Spring, Maryland to review seven peptides for potential inclusion on the Section 503A Bulk Drug Substances List. Six were recommended; one was rejected.

Why this matters: The 503A Bulks List is the only legal pathway for compounding pharmacies to prepare these peptides for individual patients with a physician's prescription. If a peptide is not on this list, has no USP monograph, and is not part of an FDA-approved drug — it cannot be legally compounded in the USA.

For peptides like BPC-157 and Semax, the 503A Bulks List is the only route to legal clinical access. A positive PCAC recommendation followed by formal FDA rulemaking would restore the legal prescription pathway for millions of Americans seeking these compounds under physician supervision.

Important

A positive PCAC recommendation is not FDA approval. It begins formal rulemaking that includes a Notice of Proposed Rulemaking, a public comment period, and a final rule. This process takes additional months to complete. Category 1 status means the FDA does not intend to take enforcement action against licensed 503A pharmacies compounding that substance for individual patients with a valid prescription.

The 7 peptides under review — what you need to know

Day 1 — July 23, 2026

Four peptides reviewed on Day 1

BPC-157 (free base and acetate)

FDA use under evaluation: Ulcerative colitis

Recommended ✓

8 Yes, 6 No, 1 Abstain

Committee voted against FDA staff recommendation — a historic outcome. Formal rulemaking still required.

BPC-157 is the most widely researched repair peptide in the compounding world. Derived from a protein in human gastric juice, it has been studied for gut healing, tissue repair, tendon recovery, and neuroprotection. Over 300 published papers document its preclinical profile.

Positive outcome

Licensed 503A compounding pharmacies could legally prepare BPC-157 for patients with a valid physician prescription. Patients could access pharmaceutical-grade BPC-157 with quality controls, endotoxin testing, and accurate dosing.

Negative outcome

BPC-157 would remain outside the compounding framework. Patients seeking it would continue to rely on gray-market RUO sources without quality guarantees.

KPV (free base and acetate)

FDA use under evaluation: Wound healing and inflammatory conditions

Recommended ✓

8 Yes, 6 No, 1 Abstain

Same vote margin as BPC-157. Formal rulemaking required.

KPV is a tripeptide fragment of alpha-MSH with potent anti-inflammatory properties. One of the few peptides with genuine oral bioavailability, making it uniquely valuable for gut-targeted research. Studied for IBD, Crohn's disease, and wound healing.

Positive outcome

Oral and injectable KPV could be legally compounded by licensed pharmacies. Particularly significant for gut inflammatory condition research given its oral bioavailability.

Negative outcome

KPV remains outside compounding framework. Gray-market access only.

TB-500 (free base and acetate)

FDA use under evaluation: Wound healing

Recommended ✓

8 Yes, 6 No, 1 Abstain

All three Day 1 repair peptides received identical vote margins. Formal rulemaking required.

TB-500 is a synthetic fragment of Thymosin Beta-4 that promotes systemic tissue repair through actin regulation and stem cell recruitment. Frequently researched in combination with BPC-157 as the Wolverine Stack for comprehensive injury recovery protocols.

Positive outcome

TB-500 could be legally compounded and prescribed. Opens the most researched injury recovery combination (with BPC-157) to the licensed pharmacy system.

Negative outcome

Remains RUO. Gray-market access only. The Wolverine Stack cannot be legally prescribed.

MOTS-c (free base and acetate)

FDA use under evaluation: Obesity and osteoporosis

Recommended ✓

7 Yes, 5 No, 2 Abstain

Slightly wider margin than the repair peptides. Formal rulemaking required.

MOTS-c is a mitochondria-derived peptide discovered in 2015 that acts as an exercise mimetic — activating metabolic pathways of physical activity. Studied for insulin sensitivity, metabolic health, and bone density. Levels naturally decline with age.

Positive outcome

MOTS-c could be legally compounded for metabolic and bone health applications under physician supervision.

Negative outcome

Remains RUO. Limited to gray-market access with no quality controls.

Day 2 — July 24, 2026

Three peptides reviewed on Day 2

Emideltide (DSIP — Delta Sleep-Inducing Peptide)

FDA use under evaluation: Opioid withdrawal, chronic insomnia, narcolepsy

Not recommended ✗

6 Yes, 7 No

The only compound rejected — by the narrowest possible margin of one vote. DSIP remains outside the compounding framework for now. A future nomination is possible.

Emideltide, commonly known as DSIP, is a nonapeptide originally isolated from rabbit brain during slow-wave sleep in 1977. It specifically promotes the deep restorative delta sleep phase. The FDA evaluation for opioid withdrawal is a particularly significant clinical application.

Positive outcome

Legal prescription access for sleep disorders and potentially opioid withdrawal support — a significant public health application.

Negative outcome

Remains outside compounding framework.

Semax (free base and acetate)

FDA use under evaluation: Cerebral ischemia, migraine, trigeminal neuralgia

Recommended ✓

8 Yes, 5 No

Day 2 cognitive peptides fared well. Formal rulemaking required.

Semax is a synthetic analogue of ACTH(4-7) approved in Russia for stroke recovery and TBI. It stimulates BDNF and NGF production, increases cerebral blood flow, and penetrates the blood-brain barrier via intranasal administration. Among the most clinically studied neuropeptides globally outside the USA.

Positive outcome

Semax could be legally compounded as an intranasal preparation for neurological indications. Would bring a 40-year clinically validated compound into the US licensed pharmacy system.

Negative outcome

Remains outside US compounding framework. Patients continue to access through gray-market channels.

Epitalon (free base and acetate)

FDA use under evaluation: Insomnia

Recommended ✓

7 Yes, 4 No

Strongest relative majority of Day 2. Formal rulemaking required.

Epitalon is a tetrapeptide derived from the pineal gland, studied for telomere lengthening via telomerase activation and circadian rhythm regulation including sleep. Dr. Vladimir Khavinson published 40+ years of Russian research on this compound.

Positive outcome

Epitalon could be legally compounded for insomnia and sleep-related applications. Brings 40 years of international research into the US licensed system.

Negative outcome

Remains outside compounding framework.

What this vote actually means — and what happens next

The PCAC's recommendation is advisory only. The FDA is not legally required to follow it — though historically the agency has generally followed committee recommendations. The path from today's vote to legal compounding involves several additional steps.

The FDA will review the committee's recommendation and decide whether to initiate formal rulemaking. If it does, it publishes a Notice of Proposed Rulemaking in the Federal Register, opens a public comment period, reviews those comments, and publishes a Final Rule adding the substances to the 503A Bulks List. This process typically takes 12 months or more after the committee recommendation.

Compounding pharmacies should not interpret today's vote as immediate permission to compound BPC-157, TB-500, or any of the other recommended compounds. Legal counsel should be consulted before making any operational changes based on this outcome.

For patients and researchers: the compounding pharmacy pathway has not yet opened. The gray market landscape remains unchanged today. What has changed is the regulatory trajectory — a positive committee recommendation significantly increases the probability that a legal compounding pathway will eventually exist for these six compounds.
