Can a provider legally say its compounded tirzepatide is 'FDA-approved'?

No. No compounded drug is FDA-approved. A provider that says otherwise is misstating the product's status, and this site records the statement as a red flag.

Does 'made in an FDA-registered facility' mean approved?

No. 503B outsourcing facilities register with FDA and are inspected, but their products are still not approved. Registration describes the facility, not the product.

Are compounded GLP-1 medications FDA-approved? No — here is what that means

Compounded semaglutide and tirzepatide are not FDA-approved. What approval covers, what compounding is permitted to do, what FDA does and does not check, and how to read a provider's disclosure.

What approval is

FDA approval is granted to a specific product: the molecule, the formulation, the strength, the delivery device, the labelling and the manufacturing process, supported by trials submitted by the manufacturer. Zepbound, Mounjaro, Wegovy, Ozempic and Rybelsus are approved products. Approval means FDA has reviewed the evidence that the product is safe and effective for its labelled use and that it is manufactured to consistent quality.

What compounding is

Compounding is the preparation of a drug by a pharmacist or physician for a patient whose needs cannot be met by an approved product, for example a different strength or the removal of an allergen. It is regulated primarily by state boards of pharmacy (503A) or, for outsourcing facilities, by FDA registration and inspection (503B). In both cases the preparation is not approved. FDA states plainly that it does not review compounded drugs for safety, effectiveness or quality before they are marketed.

What that means in practice

No product-level review. Nobody at FDA has evaluated the vial you receive. Quality depends on the pharmacy’s own processes and its state board’s oversight, or on FDA inspection for 503B facilities.
No trial evidence for the preparation. The trial results on the approved product’s label do not transfer to a compounded copy, even when the active ingredient is the same.
Ingredient sourcing matters. The active ingredient must come from a registered supplier; FDA has warned about semaglutide salt forms (semaglutide sodium, semaglutide acetate) that are not the same as the active ingredient in the approved products.
Labelling is the pharmacy’s. There is no FDA-reviewed label; instructions come from the pharmacy and the provider.

How this site handles it

Every compounded plan in the database is marked compounded, and every page that shows one carries the statement that compounded drugs are not FDA-approved. The Compounding Disclosure Index records whether each provider states this itself, names its pharmacy, and states the pharmacy’s type. A provider that describes a compounded product as approved, “FDA-approved compounded”, or “the same as” an approved product is recorded as a red flag on its profile.

What to ask a provider

Which pharmacy compounds the medication, and is it 503A or 503B? Is the active ingredient the base form used in the approved product? What is the concentration and beyond-use date? Does the provider state, in its own words, that the product is not FDA-approved? The verification guide explains how to check the pharmacy’s licence yourself.
