A closer look at weight-care offers
Why do weight-medicine offers sound so different?
Ask for the exact ingredient, product and form. A familiar name in a headline does not explain what would arrive or why it is being proposed.
Distinguish approved drugs from compounded products
What do the medicine names mean?
Your body makes a chemical message, or hormone, called GLP-1. It helps regulate both your appetite and the sugar in your blood. Drugs that mimic that message are often described as GLP-1 medicines. Semaglutide, sold as Ozempic and Wegovy, is one example; another is tirzepatide, sold as Mounjaro and Zepbound.
A generic medicine is an approved version of a branded drug.
Neither semaglutide nor tirzepatide had a generic product approved for United States marketing when checked September 26, 2026.
A version made to order has not been approved as a generic by the Food and Drug Administration (FDA).
Why does a shortage affect compounding?
A place on FDA's national shortage list can allow a medicine to be copied through compounding when the law would otherwise restrict those copies.
Semaglutide injections and tirzepatide were off FDA's national shortage list when checked on September 26, 2026. FDA had also ended the extra time it gave pharmacies and larger facilities to adjust after those shortages ended. That extra time meant FDA would wait before acting against them for breaking some shortage-related rules. A pharmacy can no longer rely on those shortages or that extra time to justify making copies.
A local pharmacy running out does not itself put a medicine on that national list.
A compounded medicine may still count as a copy under FDA's rules even with an added vitamin; that addition does not automatically change its status.
What about a newer research product?
Federal law does not allow either retatrutide or cagrilintide to be compounded, FDA says; this was checked September 26, 2026.
Some products bear research labels: “for research purposes” is one, and “not for human consumption” is another; neither labels the product as medicine for people. FDA's warning checked September 26, 2026, advises against these weight products when they are sold for human use. They may cause harm, and their quality has not been established.
Bring the exact product name to the person treating you. Ask how it differs from an approved option. Similar names do not mean the products are the same.
