Is Compounded Semaglutide Still Legal in 2026? What the FDA Has Actually Done
Short answer
Yes, but the ground has shifted and it is narrowing. Compounding semaglutide is no longer permitted simply because the drug is in shortage — the FDA declared that shortage resolved, and the enforcement grace period that followed has expired. What remains is the ordinary route: a 503A pharmacy compounding against an individual prescription where there is a documented clinical reason the approved product will not do.
In April 2026 the FDA went further and proposed excluding semaglutide, tirzepatide and liraglutide from the 503B bulks list, stating it found no clinical need for outsourcing facilities to compound them from bulk substance.1 A final determination is still pending.
This is not medical advice. Tirzeptides is an independent comparison site, not a healthcare provider. Nothing here creates a doctor-patient relationship or replaces a conversation with a licensed clinician. GLP-1 medications are prescription drugs with real risks and contraindications. Talk to a qualified provider before starting, stopping or changing any treatment.
How compounded GLP-1 became widely available in the first place
Compounding is normally a narrow practice: a pharmacy prepares a medicine for a specific patient who cannot use the approved commercial product — an allergy to a dye, a dose that is not manufactured, a person who cannot swallow a tablet. It is not a route to a cheaper copy of a drug you can already buy.
The exception is shortage. When an approved drug is on the FDA's shortage list, compounders may prepare copies of it, because the alternative is patients going without. Semaglutide and tirzepatide were both on that list through the demand surge, and that is the opening that produced the telehealth compounded-GLP-1 market almost overnight.
Once the FDA declared those shortages resolved, that opening closed. The agency published declaratory orders on the resolution and set out how it would apply the transition for compounders.2
What the two kinds of compounder can do now
The distinction matters, and most marketing blurs it.
503A pharmacies compound against an individual, patient-specific prescription. They can still compound semaglutide in principle. The constraint is that federal law bars compounding a drug that is essentially a copy of a commercially available one, regularly or in inordinate amounts. A genuinely individualised preparation for a documented clinical reason is a different thing from filling thousands of identical vials, and the further a provider sits from the former, the more exposed it is.
503B outsourcing facilities compound in bulk without patient-specific prescriptions, and they may generally only use bulk substances that appear on the FDA's 503B bulks list, or that are on the shortage list at the time. Semaglutide and tirzepatide are no longer in shortage, and the FDA has now proposed excluding them from the bulks list entirely.1
That proposal is the significant one. It was opened for public comment through 29 June 2026, and the FDA has said it will consider submissions before making a final determination. If it is finalised as proposed, the bulk-compounding route effectively closes.

The FDA is enforcing, not just proposing
This is not purely a paperwork exercise. The FDA has issued warning letters to compounders and to firms marketing these products, including for claims about compounded semaglutide and tirzepatide that it judged false or misleading under sections 502(a) and 502(bb) of the Federal Food, Drug and Cosmetic Act.3
The practical read for a buyer: a provider still selling compounded semaglutide today is not automatically breaking the law, but the category is under active regulatory pressure, and the range of providers offering it may look different in a year.
What this means if you are buying
Some straightforward questions worth asking before you prepay for a year:
- Who actually compounds it? A named, state-licensed pharmacy is a better answer than silence.
- Is there a clinical reason for compounding in your case, or is the compounded product simply the cheaper option being offered to everyone? The second is the position the FDA has been narrowing.
- What happens to a prepaid plan if supply stops? Refund terms matter more in a category under regulatory pressure than in a stable one. This is the single strongest argument against a twelve-month prepayment right now.
- Does the marketing make claims about equivalence to Wegovy or Zepbound? That is precisely the kind of claim the warning letters have targeted.
Compounded GLP-1 is not FDA-approved. The FDA does not review it for safety, effectiveness or manufacturing quality, whichever route it was made under.
The short version
The shortage justification is gone. Patient-specific compounding under 503A survives, with real limits. Bulk 503B compounding of semaglutide and tirzepatide is the subject of an FDA proposal to shut it down, still awaiting a final decision. Enforcement is live. You can still buy compounded semaglutide today; you should not assume the market looks the same in twelve months, and you should weigh that before prepaying for a year.
