Is compounded medication still legal?
Yes, but much more narrowly than in 2024. What changed, and the five questions to ask before you start.

If you are buying a low-cost weekly shot, you are almost certainly buying a compounded product. It is worth understanding what that means, because the rules changed again this year.
Compounded GLP-1s are no longer the freely marketed product they were in 2024. They remain legal in a narrower form, and the rules changed again in 2026.
What happened, and when
| When | What happened |
|---|---|
| December 2024 | FDA declared the tirzepatide shortage resolved. |
| February 2025 | FDA declared the semaglutide shortage resolved, ending the shortage-based pathway that allowed large-scale compounding. |
| 16 September 2025 | FDA issued more than 55 warning letters to online sellers of compounded GLP-1 medications. |
| 1 April 2026 | FDA reminded compounders that specific conditions must be met for compounded drugs to qualify for exemptions under sections 503A and 503B. |
| 30 April 2026 | FDA proposed excluding semaglutide, tirzepatide and liraglutide from the 503B Bulks List, saying there is no clinical need for compounded versions. |
| 30 July 2026 | Comment period on that proposal closed after an extension. |
What it means for you
- A 503A pharmacy may still compound a GLP-1 for an individual patient when there is a documented, patient-specific clinical reason — for example a required dose or formulation that the approved product does not provide.
- Routinely marketed, off-the-shelf compounded GLP-1 sold like a consumer product is not permitted under that framework.
- If the 503B Bulks List proposal is finalised, outsourcing facilities would lose the pathway they have been using to produce these drugs in volume.
- Compounded versions are not FDA-approved. The agency does not review them for safety, effectiveness or manufacturing quality the way it reviews Zepbound or Wegovy.
Worth knowing. Compounded versions are not FDA-approved. The agency has not reviewed them for safety, effectiveness or manufacturing quality the way it reviewed Zepbound and Wegovy. That does not mean they are unsafe — but it is a real difference, and anyone selling to you should be able to explain it without getting defensive.
Five questions to ask before you start
- Which pharmacy fills this, and is it a 503A or 503B facility?
- What is the patient-specific clinical reason for compounding in my case?
- What happens to my prescription — and any prepaid months — if the 503B Bulks List proposal is finalised?
- Can you move me to an FDA-approved product without restarting, and at what price?
- Is the figure I have been quoted the ongoing price or an introductory one?
Providers that answer those plainly are the ones worth your money. Our programme reviews note which ones do.
