Is Compounded Semaglutide FDA-Approved? What Changed in 2025

No. Compounded semaglutide is not FDA-approved, while brand semaglutide products such as Wegovy and Ozempic are. Since the FDA declared the semaglutide shortage resolved in February 2025, compounding of semaglutide is much more limited, and a state-licensed 503A pharmacy may generally prepare it only for an individual patient whose prescriber documents a clinical need that the commercial product does not meet. The safest path is a licensed provider, a real prescription and a licensed US pharmacy.

What "compounded" means

Compounding is when a licensed pharmacist or an FDA-registered outsourcing facility combines, mixes or adjusts ingredients to create a medication for a patient. It has a long history and a real purpose. A patient may need a different strength, a version without a certain ingredient, or a different form than what is sold commercially.

Federal law sets out two main types of compounders:

• 503A pharmacies. State-licensed pharmacies that compound for individual patients based on a prescription.
• 503B outsourcing facilities. Facilities registered with the FDA that can compound larger batches and follow federal manufacturing quality standards.

Compounded drugs can play an important role in care, but they are not FDA-approved. The FDA explains that it does not verify their safety, effectiveness or quality before they reach patients. Brand drugs, by contrast, go through clinical trials and an FDA review of manufacturing and labeling.

Why the shortage ending matters

Semaglutide and tirzepatide were on the FDA drug shortage list for a period when demand outran supply. During a shortage, federal law gives compounders more room to prepare versions of the drug. The FDA also used temporary enforcement discretion while it confirmed supply had recovered.

That window has closed. The FDA's timeline:

• Tirzepatide: shortage declared resolved on December 19, 2024. The enforcement period ended for 503A pharmacies in March 2025 and for 503B outsourcing facilities on March 19, 2025.
• Semaglutide: shortage declared resolved on February 21, 2025. The enforcement period ended for 503A pharmacies in April 2025 and for 503B outsourcing facilities on May 22, 2025.

Today, the key concept is what the FDA calls an "essentially copy." Under section 503A, a pharmacy generally may not regularly or in large amounts compound a drug that is essentially a copy of a commercially available product. A compounded drug can fall outside that definition when the prescriber determines, for a specific patient, that a change from the commercial product produces a significant difference for that patient, and documents it on the prescription. In an April 2026 update, the FDA also explained that a product combining semaglutide with another ingredient, such as vitamin B12, can still be considered an essentially copy when it is given the same way and in similar strengths as commercially available products.

In plain terms: compounded semaglutide is still possible for an individual patient with a documented clinical need, prepared by a licensed 503A pharmacy. It is not meant to be a mass-market substitute for the brand drug.

Watch for these red flags

The FDA has warned about unapproved and counterfeit GLP-1 products sold online. It has also flagged versions made with salt forms, such as semaglutide sodium or semaglutide acetate, which are different active ingredients from the approved drug. Signs to walk away include:

• No prescription or no real review by a licensed provider.
• Prices that look far lower than everyone else.
• Products labeled "for research use only" or "not for human consumption."
• Spelling errors on labels, or a product that looks different from your last shipment.
• Injectable medication that arrives warm or without proper cold packaging.
• A seller that will not name its pharmacy.

How to check that a pharmacy is licensed

You can check a pharmacy yourself in a few minutes:

1. Ask for the pharmacy name. A legitimate program will tell you which pharmacy fills your prescription.
2. Look it up with the state. For Florida, use the Florida Department of Health License Check through the Medical Quality Assurance site. For other states, the FDA BeSafeRx page links to each state board of pharmacy database.
3. Confirm the basics. According to the FDA, a safe online pharmacy requires a prescription, lists a physical US address and phone number, and has a licensed pharmacist available to answer questions.
4. Read the label. Your vial should name the pharmacy, the medication, the strength, a lot number and a beyond-use date.

How RULE handles it

Every RULE weight prescription starts with a secure online visit reviewed by a licensed provider. If the provider decides a compounded medication is appropriate for you, it is prepared by a licensed US pharmacy for you as an individual patient. We say it clearly on every program page: compounded semaglutide and compounded tirzepatide are not FDA-approved. Your provider sets the dose, and you can ask about brand options at any time.

Frequently asked questions

Is compounded semaglutide the same as Wegovy?

No. They share the same active ingredient name, but Wegovy is an FDA-approved product made by its manufacturer under FDA oversight. A compounded version is prepared by a pharmacy, has not gone through FDA review, and may include an added ingredient such as B12 or glycine.

Is compounded semaglutide legal after the shortage ended?

It can be, within limits. A state-licensed 503A pharmacy may compound for an individual patient when the prescriber documents a significant clinical difference for that patient. The broad compounding allowed during the shortage has ended.

Why do some compounded products include B12 or glycine?

Some pharmacies combine semaglutide with another ingredient based on a prescriber's order. The FDA has explained that adding an ingredient such as B12 does not on its own take a product outside the essentially copy rules, so the decision still rests on a prescriber documenting a significant difference for that patient.

How can I tell if my medication is counterfeit?

Buy only through a licensed provider and a state-licensed pharmacy, check the pharmacy license, and inspect the label and packaging. If anything looks off, do not use it, contact the pharmacy, and report problems to the FDA MedWatch program.

Talk to a licensed provider

If you want to understand your options, including brand and compounded medications, start a secure online visit. A licensed provider will review your health history and decide whether a prescription is appropriate. If it is, a licensed US pharmacy ships it to you, and you will always know which pharmacy filled it.
