How to Check an Online Peptide Doctor Is Licensed in Your State

What you are checking	Where to check it	What a good result looks like	Time
The physician's license in your state	Your state medical board's online license lookup	Active, not expired, in your state, name matches	About 2 minutes
A national cross-check	DocInfo.org (Federation of State Medical Boards)	The same physician, with your state among their licenses	About 1 minute
Identity, credential and specialty	NPI Registry at npiregistry.cms.hhs.gov	One matching record, active, credential MD or DO, a listed specialty	About 1 minute
The pharmacy	Your state board of pharmacy license lookup	Licensed, and licensed to ship into your state	About 2 minutes
Pharmacy accreditation	The pharmacy's PCAB accreditation	Accredited (a positive signal on top of licensure)	About 1 minute

All of these are free and need no login. Pepti lists its physicians by name at /providers, so you can run every check on this page against them before you start an intake.

Medical licensure in the United States is a state function. A physician licensed only in one state cannot lawfully treat a patient located in another, and telehealth does not change that. The rule is that the prescriber must be licensed in the state where the patient is located at the time of care. The Federation of State Medical Boards' board-by-board survey records that every state medical board, plus those of the District of Columbia, Puerto Rico and the Virgin Islands, requires physicians practising telemedicine to be licensed in the state where the patient is located, or registered there where a state runs a registry for interstate practice.

Two practical consequences follow:

• A license elsewhere is not enough. "Board-certified and licensed in Florida" tells you nothing if you are in Ohio.
• Where you are sitting counts, not your billing address. If you move, the license in your new state is the one that matters for future prescriptions.

Peptides are not controlled substances, so the federal rules written for remote prescribing of controlled drugs do not apply. That is why state licensure is the main legal check you can run yourself. More on the legal framework is in is peptide telehealth legit and do you need a doctor to get peptides.

Every check depends on a full legal name. A first name, a headshot or "our licensed medical team" is not something you can search.

What you should be able to find	Why it matters
Full name, including surname	The lookups search by name
Credential: MD, DO, NP or PA	Tells you which board to search; physicians (MD, DO) are licensed by the medical board, and in some states DOs have a separate osteopathic board
The states they are licensed in	You need yours on the list
Their role at the company	A medical director, a reviewing physician, or both

If the website does not show this, ask in writing before you pay: "Which physician will review my intake, and in which state are they licensed?" A legitimate provider answers with a name and a state. A non-answer is a decision.

Every state and DC runs a free online license lookup. Search for "[your state] medical board license lookup" and use the board's own website, ending in .gov or the board's official domain, rather than a third-party directory.

Enter the physician's name and check four things:

1. The license exists. A name that returns nothing at all is the strongest red flag on this page. A middle-initial difference is usually nothing.
2. It is active. Not expired, lapsed, inactive, retired, suspended or revoked.
3. It is in your state. You are searching your own state's board, so a result here is the one that counts.
4. Public actions. Most boards show disciplinary history, probation or restrictions on the same record. Read it.

A physician who holds licenses in many states will appear separately in each state's database. You only need to find them in yours.

DocInfo.org is run by the Federation of State Medical Boards, the national organisation that represents the state medical boards. It is a free public search of physician license information drawn from those boards, and it is a quick way to see the states a physician is licensed in from one place.

Use it as a cross-check rather than a replacement. If DocInfo.org and your state board disagree, trust the state board, because the board issues the license.

The National Provider Identifier is a ten-digit number assigned to US healthcare providers. The NPPES NPI Registry at npiregistry.cms.hhs.gov is the free public directory, run by the Centers for Medicare & Medicaid Services. Search by name and state.

Field on an NPI record	What it tells you
NPI number	The provider's unique national identifier
Enumeration type	NPI-1 is an individual clinician, NPI-2 an organisation
Credential	MD, DO, NP, PA and so on
Primary taxonomy	Their specialty, such as Internal Medicine or Family Medicine
State license numbers	The licenses they have recorded against their specialty
Practice address and phone	Whether there is a real location behind the name
Enumeration date and status	How long the record has existed, and whether it is active

The NPI Registry confirms identity and specialty. It does not confirm a license is current and it does not show discipline; that is the state board's job. The three sources should agree: the company's own disclosure, the NPI record and your state board.

How to read what comes back

• Specialty. A surgeon or dermatologist reviewing peptide prescriptions is not disqualified by that, but it is a fair question to ask.
• Enumeration date. A record created last month for someone presented as the medical director of a large service is a question, not an answer.
• Practice address. A real address and phone number is one of the marks the FDA lists for a safe online pharmacy operation, and the same logic applies to a practice.

The physician is responsible for the prescription. The pharmacy is responsible for what is actually in the vial: identity, strength, sterility and beyond-use dating are all pharmacy responsibilities. Checking the prescriber and skipping the pharmacy is half the job.

Check	Where	What you want to see
The pharmacy's name	Your vial label, or ask the provider before you order	A specific pharmacy name and state, not "our partner network"
State license	Your state board of pharmacy's license lookup	Active, and licensed to ship into your state (out-of-state pharmacies usually need a non-resident license from your board)
Home-state license	The board of pharmacy in the state where the pharmacy is located	Active
FDA registration	The FDA's public drug establishment registration search	Listed (registration is not approval)
PCAB accreditation	The Pharmacy Compounding Accreditation Board	Accredited

PCAB is a voluntary accreditation for compounding pharmacies covering quality and safety processes, sterile compounding procedures, ingredient sourcing and documentation, and staff training. It is not a license and does not replace the state board lookup, but it is an independent layer on top of licensure.

FDA guidance is plain on this: a safe online pharmacy is licensed with a state board of pharmacy, and if you cannot find it in your state's database, you should not use it. More on what a 503A pharmacy is and what it may compound is in what is a 503A compounding pharmacy.

Registered is not approved

Compounded medications are not FDA approved. That is true of every compounded medication from every legitimate pharmacy, including the ones Pepti uses. "FDA-registered" is a different, verifiable claim: the facility is known to the FDA and in scope for inspection. A seller that calls a compounded peptide "FDA approved" has told you how it handles every other claim. See are peptides FDA approved.

Some providers fail before you reach a license lookup.

What you see	What it means
No medical intake, or three questions and then a card form	Nobody is practising medicine
No physician named anywhere	There may be no physician
"Research use only", "not for human consumption" or "for laboratory use" in the terms	A research-chemical seller, not a medical practice
"No prescription needed"	Outside the prescription system entirely
Approval promised in advance, or in seconds	The review is decorative; a real review can end in a decline
The pharmacy cannot be named	The party responsible for sterility is hidden from you
"FDA approved" on a compounded peptide	False
Outcome promises, timelines or before-and-after photos tied to a medication	Not something a licensed prescriber does

"Research use only" deserves a sentence of its own. It is a label that lets a product ship without a prescription by stating it is not for people. No sterility, potency or identity standard comes with it, and no pharmacist or physician is accountable for what is in the vial. The detail is in research peptides vs prescription peptides and how to tell if a peptide seller is legitimate.

1. Find the physician's full name and credential on the site, or ask in writing. No name, stop.
2. Search your state medical board. Active license, your state, name matches, read any public actions.
3. Cross-check on DocInfo.org for the list of states.
4. Search the NPI Registry by name and state. Confirm credential, specialty and active status.
5. Ask which pharmacy fills the prescription. Wait for a name.
6. Search your state board of pharmacy, then the pharmacy's home-state board.
7. Check PCAB accreditation and whether lot test results are published.
8. Read the terms for "research use only". Any hit ends it.

Pass all eight and you have established what can be established from outside: identifiable, licensed people are accountable for the prescription and for the vial.

You can run every check above on Pepti before you start.

• The physicians are named. Pepti lists its physicians at /providers, with their credentials, so you can search each one in your state board's lookup, on DocInfo.org and in the NPI Registry.
• Licensed where you are. Every intake is reviewed by a physician licensed in the state where you are, usually within 24 hours. Pepti prescribes in all 50 states and DC.
• The pharmacy. Prescriptions are compounded by PCAB-accredited, FDA-registered US 503A compounding pharmacies, and the pharmacy's name is on your vial label. Lot test results, with the pharmacy and testing laboratory named, are published at /quality/lab-results.
• A real intake. The free assessment asks about your history, medications and goals. A consultation does not guarantee a prescription, and a physician can decline.

A verified license tells you a physician is accountable to a state board for the prescription. It does not tell you whether a given peptide will help you, and it is not a proxy for evidence. Compounded medications are not FDA approved, and for most peptides outside the GLP-1 class the published research is preclinical rather than large human trials. Verification answers one question: is anyone accountable for whether you should be taking this and for what is in the vial. That is worth settling first, and a provider that is honest about the evidence tends to be sound on the licensing too.
