This page separates tirzepatide’s two-target design from the status of a compounded medicine, made to order. Products approved by the U.S. Food and Drug Administration (FDA) exist. Compounded tirzepatide is not FDA-approved. A licensed provider decides whether a medicine is appropriate.

Tirzepatide acts on two receptor types. 01 ## One compound. Two kinds of signal. Tirzepatide is a peptide, a short chain of protein building blocks. It is a dual agonist: a compound that activates two receptor types. A receptor is a part of a cell that receives a signal. Its targets are GIP and GLP-1. Both names refer to hormone signals. Hormones carry messages in the body. These initials help explain tirzepatide's design, but they do not tell a reader whether it is suitable for them. In our generations guide, semaglutide has one target, tirzepatide has two, and investigational retatrutide has three. The count is a description. It is not a personal treatment plan. [Put the targets side by side](/compare/) 02 ## The ingredient name is only part of the story. A licensed pharmacy and an approved product are separate things. A pharmacy's licence does not give FDA approval to the medicine it compounds. The law limits routine copies of medicines already available. A provider must consider the patient's needs and the legal limits. The word compounded does not, by itself, settle those questions. ### FDA-approved product The U.S. Food and Drug Administration has reviewed a specific finished medicine. FDA-approved products containing tirzepatide exist. ### Compounded medicine Compounding means making a medicine to order. Compounded tirzepatide is not FDA-approved. The FDA does not review its safety, quality or effectiveness before it is sold. 03 ## The review is about a person. A provider's review can include medical history, other medicines and pregnancy plans. Tirzepatide's approved product information includes warnings that make those details relevant. A product name cannot replace that review. Questions for that conversation include: Which exact medicine is being considered? What is its approval status? Is it made to order? Which pharmacy would be involved? What follow-up would the provider arrange? This page describes the questions. It does not choose a medicine, give instructions for using one, or decide whether anyone qualifies. 04 ## A research order has a different purpose. An online product marked “not for human use” is not a prescription route. No one reviews your health as part of that research-only purchase. The FDA has warned about unapproved tirzepatide sold under research labels and about unknown product quality. 05 ## The linked U.S. route starts with review. Promise prescribes semaglutide and tirzepatide now through licensed U.S. providers. A provider reviews every request and decides whether to prescribe. Not everyone qualifies. A licensed U.S. provider reviews each request and makes the prescription decision. A product choice does not guarantee a prescription. Medications are prepared by licensed U.S. compounding pharmacies. Compounded medications are not FDA-approved. Promise is for U.S. patients only. Availability varies by state and by treatment. Promise is LegitScript-certified. This is a private check of business standards, not FDA approval or a rating of medical care. 06 ## Reading behind this page. 01 / [Tirzepatide: approved product information](https://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=487cd7e7-434c-4925-99fa-aa80b1cc776b) Records the GIP and GLP-1 targets and the status of a specific approved tirzepatide product. 02 / [FDA: what compounding means](https://www.fda.gov/drugs/human-drug-compounding/compounding-and-fda-questions-and-answers) Explains medicines made to order and how they differ from FDA-approved products. 03 / [FDA: concerns about unapproved GLP-1 drugs](https://www.fda.gov/drugs/drug-alerts-and-statements/fdas-concerns-unapproved-glp-1-drugs-used-weight-loss) Covers unapproved products, including retatrutide, sold with research-only labels. ## Keep the review in the picture.
