In 23, I got diagnosed with melanoma. It kind of like hit me hard, because I thought I was invincible, I was young, I was successful, and I thought that...

My guest on today's show, I met him in Las Vegas at a longevity conference for doctors, and I've learned a lot about him. I used to be a pharmacist, and then he had a health scare and shifted from reactive care towards prevention and long-term resilience, and made some pretty interesting products along the way.

His name is Mazen Karnaby.

So I was like, you know what? I should make something that is really at the standard that make my body work better. I didn't look at margins, I didn't look at how the label looked. I wanted real results, and that's how I started putting Zenos together. I like to do things that can make me fully understand my body, and that's what I do.

The show notes are pretty easy.

Let's go talk to Mazen.
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 with 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. And 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, I don't remember if you recall when we met, Mazen, but we were in Vegas.

**Mazen Karnaby** (4:10)
At the A4M, yes.

**Ben Greenfield** (4:12)
Yeah, at the A4M, the American Academy of Anti-Aging Medicine. That's a mouthful. And I went to, you know, like this sponsored after party or gathering or dinner or something like that.
And you and I hadn't talked before, but you told me you came out of, I think, like the pharmacy industry. Is that right?

**Mazen Karnaby** (4:30)
Yes. So I'm a pharmacist by trade and I own and operate pharmacies throughout the country. So I was one of those guys that you come in with your prescriptions and would able to like fill your drugs all over. So I was on that pharmaceutical side of things.

**Ben Greenfield** (4:48)
Did you get to wear the white coat and everything?

**Mazen Karnaby** (4:50)
It's actually funny because I was always a rebel. I never really liked to wear those things. I always thought it was like for like, it was like not something that I would want to wear.
And I actually have a funny story. I have an old lady that came to me. When I first graduated, I finished school very young. So I was 21 years old.
