What it means
Compounding has a real place in medicine, for example when a patient needs a dye-free or liquid version of a drug. During official shortages, federal rules also allowed wider compounding of drugs on the FDA shortage list.
Semaglutide and tirzepatide were on that list for a time. Between late 2024 and early 2025, the FDA announced that both shortages were resolved, which narrowed when pharmacies can legally make copies. The rules and enforcement have kept shifting, so check the FDA's current guidance.
The FDA has warned about dosing errors with compounded GLP-1 products, often from confusion between milligrams, milliliters and syringe units. Some products have also used salt forms of the drug that are not in any approved medicine.
Sunny Weigh reports legal status and label facts only. We do not list, rank or recommend compounded sellers.
Why it matters
Compounded products are not the same as the approved drugs our trial-based tools are built on.
