How to Verify a Compounding Pharmacy Before You Enroll

Step-by-step with official links

Start with the name

The first question is the most informative: which pharmacy or outsourcing facility prepares my medication? A provider that answers plainly has given you something checkable. A provider that will not name it has also given you an answer.

Then establish the registration class

There are two, and they are regulated differently.

A 503A pharmacy compounds pursuant to a prescription for an identified individual patient. It is licensed and overseen primarily by its state board of pharmacy. It is not required to meet current good manufacturing practice requirements, and it is not required to register with the FDA as an outsourcing facility.

A 503B outsourcing facility registers with the FDA, may compound without patient-specific prescriptions, must comply with CGMP, is inspected by the FDA on a risk-based schedule, and must report adverse events to the agency.

Neither route produces an FDA-approved medicine. This is the single most misunderstood fact in the category, and the misunderstanding is actively marketed.

Verify with the issuing body, never with the claimant

The verification principle is simple: a claim checked against the page that made it has not been checked.

• Pharmacy licence — the state board of pharmacy's public lookup, in the state the pharmacy operates from and, where relevant, the state it ships to. Confirm the licence is current, not merely that a record exists.
• Outsourcing facility registration — the FDA publishes a registered outsourcing facility list. If a provider claims 503B, the facility should appear on it.
• Accreditation — if PCAB, NABP or similar accreditation is claimed, check the accrediting body's own directory. Accreditation is voluntary, it expires, and it is not approval of any product.
• Prescriber — the state board of medicine licence lookup, by name. An NPI number establishes identity in a national registry; it is not evidence of a current licence, and the two are frequently conflated.

Ask about testing, precisely

"Third-party tested" is a phrase, not a fact. The useful questions are: who performed the testing, what was tested for, was it batch-level or periodic, and can I see a certificate of analysis for the batch I receive?

Potency, sterility and endotoxin are the tests that matter for a sterile injectable. A provider that can answer these specifically is running a real quality programme. One that repeats the phrase is not necessarily hiding anything, but has not yet told you anything either.

Red flags that are actually checkable

• Any use of "FDA-approved" for a compounded medication or a compounding pharmacy. No such category exists.
• Describing a compounded preparation as a generic version of Zepbound, Mounjaro, Wegovy or Ozempic. There is no generic tirzepatide or semaglutide, and compounded preparations are not therapeutically equivalent as a matter of law.
• Refusal to name the pharmacy.
• Trial results quoted for a compounded product. The trials studied the approved products.
• Prices that require an account before they are visible.

What this checklist cannot tell you

It cannot tell you whether a specific vial is safe. Verification establishes that a facility is licensed and subject to oversight; it does not inspect your medicine. It is a floor, not a guarantee, and the honest framing is that you are reducing risk rather than eliminating it.
