As of 2026, compounded semaglutide and tirzepatide are no longer broadly permitted in the United States.
Following resolution of nationwide shortages, the FDA ended its temporary enforcement discretion, meaning these medications may now only be compounded under limited, legally defined circumstances.¹–³
On February 21, 2025, the U.S. Food and Drug Administration formally declared the semaglutide injection shortage resolved.¹ In the months that followed, the FDA also confirmed the resolution of tirzepatide injection shortages and clarified post-shortage compounding expectations.²,³
Despite this, online advertisements continue to promote “compounded” GLP-1 medications. Some are legally produced and medically appropriate — others are unsafe, non-compliant, or counterfeit.
This guide explains what patients need to know in 2026 to stay safe.
What Are Compounded Medications?
Compounded medications are custom prescriptions prepared by licensed pharmacies to meet an individual patient’s medical needs when FDA-approved products cannot.
Compounding may be appropriate when⁴–⁶:
A required dose, concentration, or formulation is not commercially available
An FDA-approved drug is in a temporary shortage
A patient has a documented allergy or intolerance to an inactive ingredient
Compounding is intended to address medical necessity, not convenience, mass substitution, or price alone.
Are Compounded Semaglutide or Tirzepatide FDA-Approved in 2026?
No. Compounded semaglutide and tirzepatide are not FDA-approved medications.⁴,⁵
However, they may be legally compounded when all of the following are met:
Prepared by U.S.-licensed 503A pharmacies or FDA-registered 503B outsourcing facilities
Used for patient-specific medical needs
Produced in compliance with USP sterile compounding standards
Prescribed and monitored by a licensed clinician
This distinction — not FDA-approved but still FDA-compliant — is critical.
Why Did the FDA End Broad Compounding of Semaglutide and Tirzepatide?
During shortages of Wegovy®, Ozempic®, Mounjaro®, and Zepbound®, the FDA exercised temporary enforcement discretion, allowing compounding pharmacies to help meet patient demand.¹–³
Once manufacturing stabilized:
Semaglutide injection products were removed from the FDA Drug Shortage List¹
Tirzepatide injection products were formally declared resolved²
Compounding reverted to pre-shortage federal and state limits³–⁶
Broad, shortage-based compounding is no longer allowed in 2026.
Safe Compounding vs High-Risk GLP-1 Sources

Legitimate compounded GLP-1 medications:
Use pharmaceutical-grade active pharmaceutical ingredients (APIs)
Are sterile, potency-tested, and traceable
Require a prescription and clinician oversight
High-risk red flags include⁷–¹¹:
Prices far below typical market cost
No physical address or phone number
“Research chemical” or “not for human use” labeling
Semaglutide or tirzepatide promoted as salts
DIY powder-and-diluent kits
No Certificate of Analysis (COA)
Missing lot number or Beyond-Use Date (BUD)
No prescription requirement
How to Safely Choose Compounded Semaglutide or Tirzepatide (When Medically Necessary)
When compounding is appropriate, patients should verify⁴–⁶,⁸–¹²:
U.S.-licensed pharmacy or FDA-registered outsourcing facility
API sourcing compliant with Import Alert 66-80 (“Green List”)
Certificate of Analysis (COA) verifying identity and purity
Sterile, ready-to-inject medication
Lot number and Beyond-Use Date (BUD)
Transparent pricing consistent with pharmaceutical-grade sourcing
Physician oversight and follow-up care
Frequently Asked Questions
Is compounded semaglutide legal in 2026?
Sometimes. After the shortage ended, routine “copycat” compounding is no longer broadly permitted. Compounding must meet strict 503A/503B and patient-specific requirements.¹–³
Did the FDA ban compounded semaglutide?
No. The FDA ended broad enforcement discretion tied to shortages. Compounding is now limited to legally compliant circumstances.¹,³
Is compounded tirzepatide still allowed?
Only in limited, compliant situations. Tirzepatide injection shortages have been formally resolved, and mass compounding is not permitted.²,³
What is FDA enforcement discretion?
It is a temporary policy where the FDA may defer enforcement during exceptional circumstances such as shortages. Once resolved, standard compounding laws apply.³–⁶
What is the difference between a 503A and 503B pharmacy?
503A pharmacies compound patient-specific prescriptions under state oversight
503B outsourcing facilities compound sterile medications under FDA registration and inspectionBoth are subject to limits once shortages end.⁵,⁶,¹²
Is “semaglutide sodium” the same as semaglutide?
Patients should be cautious. FDA communications emphasize concerns with unapproved GLP-1 products and unclear formulations. Products marketed as salts or research chemicals are a major red flag.⁷–¹¹
Are “research peptide” GLP-1 products safe?
No. Products labeled for research use are not intended for human administration and may pose serious safety risks.⁷–¹¹
Why are counterfeit GLP-1 products a concern?
High demand has led to counterfeit Ozempic® entering the U.S. supply chain, prompting FDA consumer warnings.¹⁰
