Patients ask your team about the difference between PRP and exosomes, and most staff were never taught what to say. I explain it by source and by status, never by outcome. PRP is prepared in the office, that day, from the patient’s own blood. Exosomes are a manufactured product that starts with someone else’s cells, and no exosome product is FDA approved.
TLDR: The honest way to explain the difference between PRP and exosomes is source and status. PRP comes from the patient’s own blood and is prepared in the office that day. Exosomes are a manufactured product that starts with a donor’s cells, and the FDA says there are currently no FDA-approved exosome products. Nobody on your team compares results. Keep reading for the script your front desk can use and the lines to pull.

“What’s the difference between PRP and exosomes?” Your front desk is going to get that question. So is your provider. Who taught them what to say?
Here’s what I see. Most practices never got trained on doing it right when they added a regenerative service line. And where the training did happen, the practice still doesn’t know how to market the service, or how to teach its own team to answer questions about it.
So I’m going to give you the answer I’d use. Then a short script the front desk and the provider can both hold, and the sentences nobody on your team should say.
The Difference Between PRP and Exosomes: Source and Status
Your staff makes PRP in the office, that day, from the patient’s own blood. Exosomes are a manufactured product that starts with someone else’s cells, and no exosome product is FDA approved. That’s the whole honest explanation.
Source and status. PRP has a status line too, and it’s in the next section: the way a practice uses it is off-label.
Now look at what’s missing. Nothing in there says what either one does in the body. Nothing says which one is stronger. The moment the answer turns into what one of them does, your front desk is making a claim.
Why start with the source? Because the fork comes first. Is it the patient’s own tissue, or a donor’s? Everything else follows from that.
Let’s say it’s the patient’s own blood. Then it’s prepared in the room. Now let’s say it starts with a donor’s cells. Then it’s a product somebody else made, and the next question is what the FDA has said about it.
It’s the same order I use for stem cells, where the answer depends on the product’s FDA pathway first, and then on state law. So define the terms before anyone answers anything.
What PRP Is, in Plain Words
PRP stands for platelet-rich plasma. It’s platelets and plasma concentrated from the patient’s own blood, and it contains no stem cells.
I’ve worked with PRP since 2016. So what is it under the rules? You’ll hear two labels in this industry, 361 and 351. They’re shorthand for how the FDA regulates human cell and tissue products, called HCT/Ps.
But is either one the right label for PRP? No. The federal tissue rules also list what is not an HCT/P.
The definitions in 21 CFR 1271.3 put blood components on that list, and PRP is made from the patient’s own blood. So 361 and 351 are the wrong labels for PRP. For any one preparation, your counsel confirms how that rule applies.
Then there’s the equipment. The systems that prepare PRP are medical devices. They’re cleared through 510(k), the FDA’s path for moderate-risk devices, and each one is cleared for a stated use.
The FDA’s platelet and plasma separator classification gives the use for that class. It’s preparing PRP “for mixing with bone graft to improve handling characteristics.”
So the device is cleared for that use. That does not make PRP itself approved or cleared for joints, hair, skin or anything else. Those other uses are off-label practice of medicine.
What Exosomes Are, and What the FDA Has Said
Exosomes are extracellular vesicles, which are tiny particles that cells release. They are not cells. And the FDA says there are currently no FDA-approved exosome products.
Source first. Exosomes are a manufactured product. They start with someone else’s cells, and a company makes them somewhere else.
Then the status, and I’d have your team learn this part word for word. It comes from the FDA, in writing, twice.
The first is the FDA’s public safety notification on exosome products, dated December 6, 2019. It says that, as a general matter, exosomes used to treat diseases and conditions in humans are regulated as drugs and biological products. It says they are “subject to premarket review and approval requirements.”
The second is the FDA’s consumer alert on regenerative medicine products, current as of April 9, 2024. It says it in one line: “There are currently no FDA-approved exosome products.” The 2019 notification has the same sentence.
And the industry is asking too. Look at what gets searched on the way to our site, and the questions line up in a fixed order. Whether exosome products are FDA approved comes first.
Hair loss is one place to slow down. Exosome hair loss pages draw FDA attention, and where PRP differs matters there too.
The Difference Between PRP and Exosomes, Side by Side
Put side by side, the two differ on whose tissue it is, where it’s made, what it is, and what the FDA has said. Four rows your whole team can learn. I’d print the chart and keep it by the phone.
| Question | PRP | Exosomes |
|---|---|---|
| Whose tissue is it? | The patient’s own blood | Starts with a donor’s cells |
| Where is it made? | In the office, that day | By a manufacturer, somewhere else |
| What is it? | Platelets and plasma, no stem cells | Vesicles, not cells |
| What has the FDA said? | The device is cleared for mixing PRP with bone graft. Other uses are off-label | No FDA-approved exosome product exists |
What this means for your practice: Read the rows again. Not one of them says what either product does.
Why a chart, and not just a talk at the staff meeting? Because the provider and the front desk have to say the same thing. If the doctor says one thing in the room and the desk says another on the phone, which one does the patient believe?
The PRP column is yours. Your staff draws the blood and prepares it.
The exosome column is somebody else’s product. All your team can say about it is where it comes from and what the FDA has said. A supplier’s brochure doesn’t change that.
The Script: What the Front Desk Says, and Where It Hands Off
The front desk says what each one is and what its status is. Then it stops. Anything about the patient’s own case goes to the physician, and that hand-off should sound the same every time.
Here’s the staff script I’d hand a clinic’s front desk for when someone asks about the difference between PRP and exosomes. It is sample copy for your team to adapt. It is not Regen Portal copy:
- “PRP is made from your own blood. We prepare it here, the same day.”
- “The way we use PRP is an off-label use. Our physician can explain what that means.”
- “Exosomes are a manufactured product. They start with a donor’s cells.”
- “The FDA says there are currently no FDA-approved exosome products.”
- “Anything about your own case is a medical question, and our physician answers those.”
Five lines. The provider holds the same five, word for word, and then has the medical conversation the front desk can’t have. Before anyone says the exosome lines, check them against the paperwork for the product in question.
Then come the next questions. “Which one is better?” “Which one do you recommend?” “How much is PRP?”
The first two belong to the physician. The front desk doesn’t rank them and doesn’t guess. And the hand-off is not an offer. Stating the status is education, and so the desk doesn’t book a visit for exosomes off that question. And the cost question needs its own script, because price is a trust signal for someone spending their own money. I’d practice how the team handles the price question the same way.
Don’t wait for a supplier to write this for you. Clinics show us what came from their supplier, and often the gap isn’t a document. There’s nothing on how to explain the product to patients. The front desk is its own step when you launch a regenerative service line, and it comes before the marketing.
What Should Your Staff Never Say?
Your staff should never compare results or rank one over the other. And they should never say registered as if it meant approved. Each of those is a claim, and the person saying it can’t back it up.
So where do those lines come from? A rep will tell a clinic owner things that aren’t FDA compliant. It happens routinely, and it’s normal in this industry. What the rep said in the pitch turns up later in the clinic’s ads and its marketing materials, and I’ve watched it happen. The superlatives too, the “best thing since sliced bread” kind, repeated to the clinic’s patients.
Here are the ones I’d pull first.
| Do Not Use | The Problem | Say This |
|---|---|---|
| “Exosomes are stronger than PRP.” | A comparison claim with no approved product behind it | “They’re two different things.” |
| “Exosomes are the next generation of PRP.” | It ranks one over the other | What each one is made from |
| “You’ll see faster results with this one.” | A results claim nobody at the desk can back up | “That’s a medical question for our physician.” |
| “These exosomes are FDA registered.” | Registered is not approved | “No exosome product is FDA approved.” |
The bottom line: If a sentence says what one of them does, or which one is ahead, it comes out.
Softer words don’t fix any of them. The FTC’s health products guidance says vague terms like may or helps are not enough.
And registered? The FDA’s own page on what “FDA approved” means says registration “does not denote approval” of an establishment or of its drugs or devices. It’s why registered versus approved is on the list of rules I’d hold a rep to.
Think of a Practice Where Three People Give Three Answers
Think of a practice with one physician, two medical assistants, and an office manager who covers the phones and the social messages. It has done PRP for nearly ten years. Now patients are asking about exosomes, because they keep reading about them online. This scenario is illustrative and does not describe any Regen Portal client.
The Challenge: In one week, three patients ask about the difference between PRP and exosomes. The office manager says one thing on the phone. A medical assistant says another, and it’s a line from a rep’s handout. The physician gives a third answer in the room.
The Approach: The physician owns the practice and writes the answer down. Source and status, five lines, with the chart by the phone. The team says it out loud at one staff meeting.
The Compliance Check: The owner reads every line against the documents. The lines about results come out, and so does the word registered. Anything medical goes to the physician, and counsel reviews the final wording.
What Changed: The practice had one answer in place of three. The front desk knew where to stop. And the physician stopped hearing the rep’s lines repeated back in the room.
Frequently Asked Questions
Are Exosomes Stronger Than PRP?
Nobody can say that in marketing. Stronger is a comparison claim, and there is no FDA-approved exosome product behind it. If a patient asks your team this, the honest reply is that they’re two different things, and the medical part belongs to the physician.
Is PRP a Stem Cell Treatment?
No. PRP is platelets and plasma concentrated from the patient’s own blood, and it contains no stem cells. If your website or your staff call it a stem cell treatment, that’s the wrong label. I’d check the website and the phone script, and I’d fix it today.
Are Exosomes Stem Cells?
No. Exosomes are extracellular vesicles, which are tiny particles that cells release. They come from cells, and they are not cells. So your team says vesicles or particles, never stem cells, and it still says no exosome product is FDA approved.
What If a Rep Told Us Exosomes Are FDA Registered?
Then ask what is registered, and ask for the document. Registered is not approved, and the FDA says there are currently no FDA-approved exosome products. A rep’s line shouldn’t reach your patients until you’ve read what’s behind it. Counsel decides what it means for your practice.
Can I Put the Difference Between PRP and Exosomes on My Website?
As education, yes, and only as education. You can explain what each one is and state the status, and that’s where it stops: no results, no ranking, nothing that reads like an offer. The same goes for what you post on social. Counsel reads the wording before any of it goes live.
Key Takeaways
- Explain the difference between PRP and exosomes by source and status, never by outcome.
- The source of PRP is the patient’s own blood, and the office prepares it that day.
- Exosomes are a manufactured product that starts with a donor’s cells.
- The FDA says there are currently no FDA-approved exosome products.
- The front desk and the provider hold the same script, and medical questions go to the physician.
- Stronger, next generation and FDA registered come out of every answer.
Want Us to Handle This?
So it all goes back to source and status. Once your whole team says those two things the same way, the difference between PRP and exosomes is a short conversation.
This is part of what I do. I’d treat marketing compliance for your front desk the same way as the website: one sentence at a time, with the documents open. If a rep’s handout is what your team has been reading from, start there.
PS: Call your own front desk and ask the question, then write down what you hear. Reach out when you need help.
