The regular MSCs have about a 1% ability to home and go where they're supposed to go. But the mucel has a 15% chance, so it's 15 times higher. And then when they go there, they migrate into damaged tissue. And then when they do, they'll pick up the proteins and they will start to express as if they are one of the cells in those tissues.

Welcome to the Boundless Life with me, your host, Ben Greenfield. I'm a personal trainer, exercise physiologist, and nutritionist, and I'm passionate about helping you discover unparalleled levels of health, fitness, longevity, and beyond.
In this episode, one of my favorite guests, Dr. Matt Cook, you'll learn all about the amazing future of regenerative medicine, the new sexy alternative to stem cells, some of the best peptide stacks, and where you should actually get peptides now, and a whole lot more. All the show notes are gonna be at bengreenfieldlife.com/cook2026. Here we go.

Hey, everybody listening in, you just jumped in on Matt Cook's and my little pre-show banter.
You know, I got Matt a pretty sick Jason Momoa hoodie, because frankly, he's often mistaken for Jason Momoa when he's at his clinic, mostly due to his like cannonball shoulders and his arms that just like keep ripping the sleeves. So I got him a Jason Momoa hoodie, and look at that, I got him a Jason Momoa hoodie, and on the back it had Matt's tagline, which is this is going to be amazing. Amazing. This podcast is going to be amazing. And you know, I texted Matt like an hour ago and told him he should wear his Jason Momoa hoodie, which was apparently stolen, but I'm wearing the Willie Nelson shirt that Matt got me. So there you have it. And we should probably just address the elephant in the room for new listeners, which isn't who Matt Cook is, but the fact that Matt Cook and I recorded a country music album at a studio in LA.

**Ben Greenfield** (2:28)
It's at, where is it, Matt?

**Dr. Matt Cook** (2:31)
rockyroutesmusic.com, I think. There's a lot more where that came from.

**Ben Greenfield** (2:37)
Oh, a lot more.

**Dr. Matt Cook** (2:38)
There's a lot more of where that came from. Yeah. Yeah. I need to retire soon so we can just play country music.

**Ben Greenfield** (2:46)
So, I think, you know, I was talking with my sons this morning, and they said, how many times has Matt been on the podcast?

**Dr. Matt Cook** (2:54)
And I said, I think this might be his eighth appearance, making you possibly at the top, if not near the top, of the most repeated guest on my show. How cool is that?
If you get on seven times, you get a Jason Momoa hoodie. It's like on Saturday, they give you the jacket. That's where you get the hoodie. As long as your guns match the hoodie. So, all the show notes for everything that Matt and I are about to discuss, because Matt is one of the most brilliant voices in all of regenerative medicine, and you're going to want the juicy show notes, are going to be at bengreenfieldlife.com/cook2026, bengreenfieldlife.com/cook2026.
Matt's clinic is Biorecept Medical in San Jose, and people fly in from all over the world to see him. And a lot of the things that we talk about today are also things that you could bring up with your own doctor in terms of the type of stem cells and peptide approaches and things that Matt implements in his practice. So was that an okay introduction, Matt? Are you happy with that? I'm 100% of the time, I'm happy with you, Ben. Okay. All right. Good. So I think I already said twice since this podcast started, the phrase regenerative medicine. How do you actually explain that to people, what that actually is? Basically, there's a set of products that basically came out over the last 20 years, which is stem cells, exosomes, and peptides, which are the products of regenerative medicine. But regenerative medicine is actually practicing medicine using those tools, and they work by different mechanisms and in different ways. But basically using tools, and then there's a big overlap because basically, the other thing that happened over the last 20 years is an explosion in the improvement in precision medicine tests or functional medicine tests. And so I think regenerative medicine is basically doing a deep dive in terms of understanding biological processes happening in the body with basically all of the new tech that includes testing but also fundamentally is going to include wearables and all of these ways to assess the body and then using basically new approaches to regulate and optimize biology so that the body can heal itself and get it self-functioning great. Yeah, related to how this deliver, I was at a clinic about three months ago and they were talking about their use of stem cells and pepsides and exosomes, kind of like, I guess you might define those as the holy trilogy of the biologics, if you want to call them that, used in regenerative medicine. And they weren't really using much like guided imaging for delivery. And I've run into that a few times. That's something that you and I have talked a little bit about in the past. But for you, from what I can tell, the ultrasound kind of fits into the picture pretty heavily, yeah? Yeah, so the ultrasound is everything. And I had five or six times that are like crazy moments in my life. And I was an anesthesiologist. And basically, what I would do is I would do nerve blocks to put a part of the body to sleep so they could do surgery. And the way we used to do it is we would take a needle that was connected to an electrical stimulator. And then you'd go and we would touch the nerve on the neck and then the arm would start twitching like this. And we would turn it down and then we would put numbing medicine around the brachial plexus. So it's super crazy. And then the other way we would do it is if a nerve was next to an artery, we would stick a needle into the artery and then pull back. And then when that stopped having blood, we would inject local anesthetic around those nerves. This was from like for me 1998 to 2001 And so then somebody calls me and they go, you're not going to believe it. I go, what's that? And they go, there's a ultrasound and you just look at a nerve. And then you put a needle right next to it. You don't even need to touch it. And you put a halo of fluid around it.
