Compounded GLP-1 Medications: What Patients Should Know
Compounded GLP-1 drugs were made while shortages allowed it; those shortages are now resolved. Here is what the FDA has said and what it means when you choose a program.

Compounded GLP-1 medications are copies of FDA-approved prescription drugs such as semaglutide and tirzepatide, made by compounding pharmacies during the period those drugs were in shortage. In the United States, the FDA has declared both shortages resolved, and large-scale compounding of these products has wound down. If you are considering a GLP-1 weight loss program, understanding the difference between FDA-approved medication and compounded copies matters for safety, dosing, and quality.
What is a compounded medication?
Compounding is the practice of preparing a customized medication, usually because an approved version is unavailable, is in shortage, or cannot be tolerated by a specific patient. During the GLP-1 demand surge, compounding pharmacies began producing copies of semaglutide and tirzepatide under temporary allowances tied to the shortage. Those allowances were tied to shortage status, and that status has changed.
The shortages are now resolved in the United States
The FDA formally declared the tirzepatide shortage resolved in December 2024 and the semaglutide shortage resolved on February 21, 2025. Transition periods allowed compounding to continue for a limited time, and those periods have passed. Large-scale compounding of semaglutide and tirzepatide copies is generally no longer permitted, and in April 2026 the FDA proposed removing semaglutide, tirzepatide, and liraglutide from the bulk drug substances list used for bulk compounding, a step that would close the remaining industrial-scale pathway.
| Medication | Shortage status | What it means now |
|---|---|---|
| Semaglutide (Ozempic, Wegovy) | Declared resolved February 21, 2025 | Compounding of copies allowed only under limited, patient-specific circumstances |
| Tirzepatide (Mounjaro, Zepbound) | Declared resolved December 2024 | Same limited scope; transition periods have ended |
| Any GLP-1 bulk compounding | FDA proposal in April 2026 to remove these from the bulk list | Industrial-scale compounding would no longer have a legal pathway |
What the FDA has warned about compounded GLP-1s
- Compounded drugs are not FDA-approved and have not been reviewed by the FDA for safety, effectiveness, or quality.
- A July 2024 FDA alert described dosing errors with compounded injectable semaglutide, some requiring hospitalization, driven mainly by confusion between milligrams, milliliters, and units when drawing from multi-dose vials.
- Some compounders use salt forms such as semaglutide sodium or semaglutide acetate, which are different active ingredients from the base semaglutide in approved products, with roughly 15% less active drug per milligram in the sodium form.
- Adverse event reports have risen: 605 for compounded semaglutide and 545 for compounded tirzepatide as of July 31, 2025, plus sterility and contamination-related recalls of some compounded products.
What this means when you choose a program
A program built around compounded GLP-1 copies may not be operating within current rules, and the product you receive may not have been reviewed for quality or accurate dosing. A physician-led weight loss program evaluates your health history first, works with appropriate medication options, and monitors your response over time. That is the difference between buying a vial and being treated as a patient.
