My name is Ben Greenfield, and on this episode of the Boundless Life Podcast.

**Jimmy St. Louis** (0:04)
Nobody had really defined the standard of care in the longevity space, but the consumer journey in my perspective is... F***.

In this show, I interview Agentis founder, Jimmy St. Louis in Nashville, where I traveled to see some of the really cool things that he's rolling out at longevity clinics around the country. He's a great athlete, former NFL football player, cross-country athletes, CrossFit competed pretty heavily in that. Rowing and his story is pretty inspiring.

**Jimmy St. Louis** (0:38)
How do you change health care? How do you help advance healthier, happier lives? But do so by driving the standard of care, like truly defining the standard of care in longevity health care. When people hear that, they think, oh, f***.
Now, tell me how you're doing that. What's the easiest, simplest solutions to help me embark on this journey?

Let's go.
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.
I spent 20 years measuring and optimizing everything about my body. Deep performance metrics, cold stress, heat stress, sleep scores, blood panels, peptide protocols, testosterone, telomeres, VO2 max, you name it. And somewhere in the middle of building what looked like perfect life, I almost lost the life that I was building it for. Boundless, the man who became human was a brand new feature documentary that follows what happened when the optimization framework that I spent two decades constructing ran headlong into the things that metrics could never measure, my marriage, my sons, my faith. The private archive footage in this documentary has never been seen publicly. Some of it I debated even including at all. It shows basically the worst of what happens when longevity becomes the ultimate goal and how you and I can turn that around to become fulfilled by what's truly important in life. Now this is not just another biohacking film. It's an honest look at what it costs to chase the ceiling on human performance told through real footage of one family, my family finding that out. I'm giving you the chance to join me for the brand new live premier tour of this new film in a city near you. Here's what the night looks like. You watch the film, me and my family in a theater, and then you experience a live episode of the Boundless Life podcast on stage with open Q&A, real questions, no filters. My wife, Jessa, and my sons, River and Taryn will be there with us as well. VIP ticket holders get to join for an exclusive after party with upgraded food and drinks. This Boundless Life tour kicks off in LA on July 24th, Austin on August 20th, New York City on August 6th, Miami coming down the pipeline, London coming down the pipeline, more cities to be announced. Tickets are on sale now. Grab them now before they're gone at boundlessdoc.com. That's boundlessdoc.com.
And I hope to see you there. Dude, that was super fun yesterday, geeking out of the clinic, trying all the things.

**Jimmy St. Louis** (3:59)
Yeah, man, there's a lot of new things there. And our goal to just help educate and get people access.

**Ben Greenfield** (4:04)
Yeah, what did we do? We did cryo.
I did cryo. You chickened out. Red lightbed. Thought about the hyperbaric, but ran out of time. Did ozone, exosomes. You did NAD or Niagen.

**Jimmy St. Louis** (4:21)
I did Niagen.

**Ben Greenfield** (4:22)
What's the difference?

**Jimmy St. Louis** (4:23)
Yeah, so Niagen is essentially a precursor to NAD. And I found this for me personally. I love to do end of one experiments.

**Ben Greenfield** (4:31)
Yeah.

**Jimmy St. Louis** (4:32)
I've actually found that energy levels after Niagen increased almost immediately and had been through more, I guess, aggressive NAD protocols, if you will.

**Ben Greenfield** (4:40)
Yeah.

**Jimmy St. Louis** (4:41)
And really didn't notice a ton of difference.

**Ben Greenfield** (4:42)
And you told me yesterday, you like stacked them at one point and you were on fire.

**Jimmy St. Louis** (4:47)
It was like.

**Ben Greenfield** (4:47)
Like in a good way.

**Jimmy St. Louis** (4:48)
I mean, yeah, just like.

**Ben Greenfield** (4:49)
So you do.

**Jimmy St. Louis** (4:50)
Lit up afterwards.

**Ben Greenfield** (4:51)
NAD IV and then you did a Niagen IV.

**Jimmy St. Louis** (4:55)
Yeah, and I was just in there with a friend and was like, I've got time, so we'll try this. And that stack was was pretty cool.
