Approved medicine
A reviewed product
As of September 2026, semaglutide, tirzepatide, and liraglutide appear in medicines the FDA has approved for specific uses.
Each brand is approved for certain health problems, so ask whether the brand you are offered is the one approved for your reason, such as diabetes or weight.
Compounded medicine
Made by a pharmacy
A compounded medicine is mixed to order by a state-licensed pharmacy, or by a larger outsourcing facility that registers with the FDA.
It has no FDA approval as of September 2026, and nobody at the agency checks it before it goes on sale.
Research-use product
Not a treatment route
A chemical sold with “research use only” wording is not a patient medicine.
Mixing water or an injection guide beside it is a reason to leave.
