No, not as a regular clinic service, as we read FDA’s public statements. FDA’s own words are, “[There are currently no FDA-approved exosome products](https://www.fda.gov/vaccines-blood-biologics/safety-availability-biologics/public-safety-notification-exosome-products).” The agency regulates exosomes used on people for a disease or a condition as drugs and biological products. FDA has also said such a product may be given to a person only when an Investigational New Drug application, or IND, is in effect. A state law does not change that. This post shows where each of those statements comes from.

## Are exosomes FDA approved?

When a doctor calls me, the first thing they ask is, are stem cells legal or illegal? This post takes that same kind of question and puts it to one kind of product. So let’s start with the word approved.

FDA answered the approval question in a public notification dated December 6, 2019. The sentence quoted above comes from that page, and it is still there today.

The same notice says what kind of product FDA sees. It reads: “As a general matter, exosomes used to treat diseases and conditions in humans are regulated as drugs and biological products under the Public Health Service Act and the Federal Food Drug and Cosmetic Act and are subject to premarket review and approval requirements.”

Here it is in plain words. FDA sees an exosome product used for a disease or a condition as a drug and as a biological product. A product like that has to go through FDA’s review, and be approved, before it is sold.

FDA made the point again in a [consumer alert on stem cell and exosome products](https://www.fda.gov/vaccines-blood-biologics/consumers-biologics/consumer-alert-regenerative-medicine-products-including-stem-cells-and-exosomes). The page we opened was current as of April 9, 2024, and it says, “Exosome products are also regulated by FDA.”

Is there an approved product now? We looked. FDA keeps a [list of approved cellular and gene therapy products](https://www.fda.gov/vaccines-blood-biologics/cellular-gene-therapy-products/approved-cellular-and-gene-therapy-products), and the page we opened on October 5, 2026 was current as of September 17, 2026. No exosome product appears on it.

That list changes, so open it yourself on the day you need it.

## What is an exosome?

Here is the biology, and only the biology.

An exosome is a tiny particle that a cell releases. Scientists place exosomes inside a wider group called extracellular vesicles, or EVs. The field’s consensus paper, known as [MISEV2023](https://isevjournals.onlinelibrary.wiley.com/doi/10.1002/jev2.12404), defines EVs as “particles that are released from cells, are delimited by a lipid bilayer, and cannot replicate on their own.”

In plain words, picture a very small bubble with a fatty skin. A cell lets it go, and it cannot copy itself. That last part tells you an exosome is not a cell.

An exosome also carries cargo from the cell that made it. So two questions follow about any vesicle: which cell made it, and how was it collected? Those are lab questions, and a later post in this series is about how to ask them.

That is where this post stops on the science. It tells you what an exosome is. It does not tell you what an exosome does in a patient, because FDA has not approved any exosome product for any use.

## What does FDA say is needed before an exosome product is given to a patient?

FDA says the product has to be in research that FDA oversees. Its [patient page on regenerative medicine products](https://www.fda.gov/vaccines-blood-biologics/consumers-biologics/important-patient-and-consumer-information-about-regenerative-medicine-therapies) lists exosomes by name among the unapproved products it covers. Then it says, “Before approval, these products require FDA oversight in a clinical trial.”

The same page says who has been told. FDA writes that it “has repeatedly notified manufacturers, clinics, and health care practitioners of the need for Investigational New Drug applications (INDs) to legally administer these products.” Clinics and practitioners are named right next to the companies that make the products.

FDA was even more direct in an online session it held for practitioners on November 17, 2022, and it posted [the transcript](https://www.fda.gov/media/165501/download). The speaker is an official from the compliance office of FDA’s biologics center. The official says exosome products “may only be distributed to participating investigators and/or administered to humans if a sponsor has an Investigational New Drug application in effect, an IND.”

So what is an IND? FDA’s [IND page](https://www.fda.gov/drugs/types-applications/investigational-new-drug-ind-application) starts from the federal rule that a drug must be approved before it is shipped across state lines. It calls the IND “the means through which the sponsor technically obtains this exemption from the FDA.” In plain words, an IND lets a sponsor test a product in people before it is approved, with FDA watching. It is not an approval, and it is not a license to sell.

Look at two words in the official’s sentence: participating investigators. Under an IND, the product goes to the doctors who are part of the research. A clinic that buys a vial from a rep is not one of them, unless the sponsor has brought that clinic into the research.

So the first thing to ask about any exosome product is short. Is an IND in effect for it, and am I an investigator on that IND? The IND gets its own post later in this series.

## What does it mean when a rep says the product is FDA registered?

It means the company filed a registration, and that is all it means. A rep you like can still be wrong about the law, so each answer in this part of the post ends with FDA’s own words.

FDA has a consumer page called [Is It Really ‘FDA Approved’?](https://www.fda.gov/consumers/consumer-updates/it-really-fda-approved). It says registration of a company, or listing of a drug or device, “does not denote approval of the establishment, the drug or device.” The same sentence ends with these words: “nor does it mean that a product may be legally marketed.”

FDA’s patient page adds a second point, about research listings. It says, “The inclusion of a product in the clinicaltrials.gov database or the fact that a firm has registered with FDA and listed its product does not mean the product is legally marketed.”

So a registration number is not an approval, and a listing on a research website is not an IND in effect. Ask for the IND number, and ask for FDA’s letter about it. We covered the words cleared, approved and registered for devices in our post on [whether PRP is FDA approved](https://regenmedacademy.com/is-prp-fda-approved/).

## Is an exosome product a 361 product?

FDA has said it is not. To see why the claim comes up, you need one piece of background.

The federal tissue rules have a lighter track for some human cell and tissue products, which are called HCT/Ps. The rule is [21 CFR 1271.10(a)](https://www.ecfr.gov/current/title-21/chapter-I/subchapter-L/part-1271/subpart-A/section-1271.10). It opens this way: “An HCT/P is regulated solely under section 361 of the PHS Act and the regulations in this part if it meets all of the following criteria:” Four tests follow. A product on that track does not need FDA’s approval before it is sold, so “it’s a 361” is a way of saying no approval is needed.

FDA took up that claim in the 2022 session for providers. The official said, “We often see Wharton’s jelly products marketed as 361 HCT/Ps, and the same really applies to exosomes.” The next sentence in the transcript is four words long: “That is not correct.” The official then said again that these products are regulated as drugs and biological products.

FDA said much the same thing in 2019. Its notice says clinics may claim their products fall outside the rules for drugs and biological products, and FDA’s reply is “that is simply untrue.”

So when a rep says 361, ask one thing. Which FDA document says this product is a 361 HCT/P, and can I have a copy? We explain the four tests in a later post.

## What does “for research use only” mean on a vial?

Read the label the way it is written, because research use is not patient use.

Federal rules do describe a research label for drugs. [21 CFR 312.160](https://www.ecfr.gov/current/title-21/chapter-I/subchapter-D/part-312/subpart-G/section-312.160) covers drugs shipped for lab tests and for research in animals. It gives the words for the label: “CAUTION: Contains a new drug for investigational use only in laboratory research animals, or for tests in vitro. Not for use in humans.” In vitro means in a dish or a tube, outside a living body.

I can’t tell you which rule a given vendor’s label comes from, so ask the vendor. The label in the federal rule ends with five plain words: “Not for use in humans.”

FDA has also looked at research wording on a vendor’s website. FDA posts its letters in a public [warning letter database](https://www.fda.gov/inspections-compliance-enforcement-and-criminal-investigations/compliance-actions-and-activities/warning-letters), and we opened one dated May 5, 2025. In it, FDA notes that the firm’s site said its products were for “research and investigational purposes and are not approved for general medical use.” FDA’s next words are, “there is no IND in effect for your product.”

The sentence after that one reads, “Nor is there a valid biologics license.” So the research wording did not answer FDA’s question, which was whether an IND or a license was in place.

## Is a topical or cosmetic exosome product different?

The word cosmetic on a label does not decide it. Federal law sorts a product by its intended use, and FDA explains how on a page called [Is It a Cosmetic, a Drug, or Both? (Or Is It Soap?)](https://www.fda.gov/cosmetics/cosmetics-laws-regulations/it-cosmetic-drug-or-both-or-it-soap), and the page we opened was current as of September 11, 2024.

Start with the two definitions. A cosmetic is an article “intended to be rubbed, poured, sprinkled, or sprayed on, introduced into, or otherwise applied to the human body…for cleansing, beautifying, promoting attractiveness, or altering the appearance.” A drug includes “articles intended for use in the diagnosis, cure, mitigation, treatment, or prevention of disease.” It also includes articles “intended to affect the structure or any function of the body.”

Can one product be both? FDA says yes: “Some products meet the definitions of both cosmetics and drugs.” It also says there is no middle category, because “the term ‘cosmeceutical’ has no meaning under the law.”

So how does FDA decide what a product is intended for? The first way on its list is “Claims stated on the product labeling, in advertising, on the Internet, or in other promotional materials.” Then the page adds, “Certain claims may cause a product to be considered a drug, even if the product is marketed as if it were a cosmetic.”

FDA gives examples of claims like that. Two of them are claims that a product will “restore hair growth” or “regenerate cells.”

FDA has applied this thinking to exosome products, and one example is a warning letter dated September 1, 2023. FDA wrote this to a firm: “Although you stated during the inspection that your exosome products are for cosmetic use, you have continued to market your exosome products to treat diseases or conditions, for example, skin damage.” The firm had called its products cosmetic, and FDA looked at the marketing.

There are three limits to state plainly here.

- FDA’s cosmetics page does not mention exosomes at all. Nothing on it says an exosome product is a cosmetic.
- The page says cosmetic products and ingredients, apart from color additives, “do not require FDA approval before they go on the market.” So the word cosmetic never tells you FDA reviewed the product.
- The page says nothing about injecting a product, or about pressing it into the skin with needles. Do not assume the cosmetic definition covers those uses.

What do you do with a product that is sold to you as a cosmetic? Take the label and the brochure to your own attorney before anything else happens. This post cannot tell you that any exosome product is a lawful cosmetic, and a rep cannot tell you that either.

## Is exosome treatment legal in the USA if my state has a stem cell law?

A state law does not change FDA’s answer. State law does not override federal law, and the federal status of exosome products is the one FDA has stated since 2019.

What can a state do? A state can set who may perform a procedure, and under which license. It does not approve a drug or a biological product, because that job belongs to FDA.

So the order to work in is federal law first, then your state, and then your own license. What you may perform is set by your own state license and board. A Certificate of Completion does not extend it.

State law in this field changes, sometimes more than once a year. Our reading of each state, with its sources and the date we checked, is on the [rules by state page](https://regenmedacademy.com/regenerative-medicine-laws-by-state/). It is a starting point, not legal advice.

## What if the rep has an answer for everything?

Let’s say a rep sits down in your office with a box of vials. In ten minutes you hear that the lab is FDA registered, that the product is a 361, and that clinics near you already use it. What do you do?

You ask for three things in writing, and you say you will read them with your attorney.

- The IND number, and FDA’s letter that acknowledges the IND.
- The FDA document that says this product is a 361 HCT/P.
- The full label, and every brochure and web page the company uses to sell the product.

Why those three? Each one maps to something FDA has said about INDs, about the 361 claim, and about how it reads a product’s intended use. Getting all three still does not make the product usable in your clinic.

And the clinics down the road? What another clinic does is not a legal status. FDA wrote its 2019 notice at a time when clinics were already offering these products, and the notice says so.

## What can my clinic do today?

You can learn, you can ask for answers in writing, and you can wait. None of the three needs a vial in your office.

Learn the rules first. Our free FDA legal foundations mini course takes about 45 minutes, it is self-paced, and it has five lessons. Then read the FDA pages linked in this post, because they are short and they are the source.

Keep exosome claims off your own website and out of your social posts. FDA reads intended use from marketing, and a clinic’s own pages are marketing too. Have your attorney read anything you plan to post.

One more caution belongs here. Do not assume your malpractice policy covers a product that FDA has not approved. Coverage is a question for your carrier, and the answer belongs in writing.

Then join the wait list for our online exosome course. Reading the rules before a rep visits takes some work, and it is the part of this that you control.

## What does Regen Med Academy teach about exosomes, and what does it not?

Regen Med Academy is an education company. We sell education and nothing else, which means we do not sell a device or a biologic. We are not tied to any vendor, and we take no commission.

Providers ask us when our courses run. Our exosome course is online, it is education only, and it is wait list only. We do not have a hands-on exosome course, so there is no date to request.

Our science faculty includes [Carla Mazzeo, PhD](https://regenmedacademy.com/dr-carla-mazzeo/). She is a co-author of MISEV2023, the paper quoted above. She has been in exosome and extracellular vesicle science since 2004, and she founded the EV Core Facility at Boston University.

We cannot tell you where your license stands, because the authority on your own scope is your licensing board, not us.

## Frequently asked questions

### Can I use an exosome product off-label?

No. Off-label describes a new use of a product that FDA has already approved. FDA’s own page says, “[Unapproved use of an approved drug is often called ‘off-label’ use](https://www.fda.gov/patients/learn-about-expanded-access-and-other-treatment-options/understanding-unapproved-use-approved-drugs-label).” With no FDA-approved exosome product, there is no label to be off of. The term does not fit, so ask a rep who uses it which approval they mean.

### Does it matter if the exosomes come from the patient’s own cells?

FDA’s patient page does not draw that line. It describes “unapproved products whether recovered from your own body or another person’s body,” and exosomes are on the list that follows. So where the cells came from does not, by itself, move a product out of FDA’s review. Ask the same IND question either way.

### What should I say when a patient asks me for exosomes?

Tell them what FDA says, in FDA’s words. The 2019 notice tells patients to “Ask if the FDA has reviewed the treatment.” It also says they can ask for “the FDA-issued Investigational New Drug Application (IND) number.” Those are fair questions for a patient to put to any clinic, and that includes yours. Do not describe what an exosome product would do for them.

### Is exosome therapy legal if the patient signs a consent form?

No. A consent form does not change what FDA says the product is. FDA’s [2019 notice](https://www.fda.gov/vaccines-blood-biologics/safety-availability-biologics/public-safety-notification-exosome-products) does talk about consent, but only as part of research. It says, “To participate in a clinical trial that requires an IND application, you must sign a consent form that explains the experimental procedure.” A form from your own clinic is not an IND.

### Does Regen Med Academy offer hands-on exosome training?

No. Our exosome course is online, it is education only, and it is open as a wait list. We do not sell exosome products, and we do not recommend one. If you want the course when it opens, you can [join the exosome wait list](https://regenmedacademy.com/contact/?course=exosomes-wait-list).

## Key takeaways

- FDA says there are currently no FDA-approved exosome products. None was on FDA’s approved list when we checked it on October 5, 2026.
- FDA regulates exosomes used for diseases and conditions in people as drugs and biological products.
- FDA has said an exosome product may be given to a person only when an IND is in effect.
- Registered, 361, research use and cosmetic are words a rep may use. None of them is an FDA approval.
- A product’s intended use is read from the claims made for it, so a cosmetic label does not settle what the product is.
- State law does not override federal law. Your own scope is set by your state license and board.
- Today a clinic can learn the rules, ask for answers in writing, and join the wait list for our online course.
