Summary

Peptides are everywhere right now, but most people don't actually understand how they work or how to use them intelligently. That's why I wanted to sit down with Kyal Van Der Leest, founder of LVLUP Health, to cut through the noise and talk about what really matters if you care about performance, longevity, and staying sharp.

In this episode, we get into oral peptides and why some work while others never will, the truth about SLU-PP-332 and exercise mimetics, and how gut health quietly drives hormones, inflammation, and recovery. We also talk about fat loss without stimulants, brain performance without frying your nervous system, and how to mitigate real life stress like travel, alcohol, and poor sleep without blowing up your progress.

Kyal shares his background in nutrition and naturopathy, how peptides changed his approach to health, and why nuance always beats hype. If you want tools that actually move the needle, this episode will help you think more clearly about what you're using and why.

0:00.0	Welcome to the Chris Getten podcast where we dive deep into the science of building a stronger physique,
0:11.9	unlocking the secrets of anti-aging and optimizing your health through cutting edge biohacks,
0:17.6	fitness strategies and mental resilience. I've been a personal trainer for nearly 30 years now and voted the number one transformation
0:25.2	trainer by governing bodies such as PT Academy, bodybuilding.com, and trainerize.
0:31.9	I am the co-founder of unmatched supplements, co-founder of the Chris Kethyn Jims franchise, and co-founder of my
0:39.6	online coaching platform, Chris Kethin Coaching, and author of several books. I'm a hybrid athlete,
0:46.2	a natural pro bodybuilder, and I've competed in events such as Iron Man Triathlon, Ultramarathon,
0:52.0	Spartan, and many more. My goal with this podcast is to cut through
0:56.7	the noise of fitness myth, misconceptions, and deliver clear protocols, actual tips, and real
1:04.1	resilience and science to help you optimize your physique, elevate your physical and mental
1:10.4	health span, and, of course, enhance your

1:21.4	podcast. Today, we have a guest. We've been doing so many solo episodes as of recent, but I thought it's about time that we had a guest here.
1:29.7	And I've known this person probably about a year and a half, met him first at Hack Your Health,
1:35.0	but I'd known of Karl. We'd known of each other for quite a while before that. And he is the
1:41.2	owner of a peptide company that you've heard me talk about and recommend for quite a time here now. And that's called Level Up. So this is Kyle van der Least. Hopefully I've got that right. Now, you probably recognize him because he's been on like everybody's podcast. So there's a lot of pressure on me here and a lot of pressure on Kyle because he's going to have to deliver more than
2:01.3	what he's done in the past. And he's been on people's or a lot of friends' podcasts like
2:06.1	Ben Greenfield, Angela Foster, Nat Niddem, Luke Story, Dr. Tina Lucasown, you know, those are just
2:13.8	people off the top of my head. You know, I know all of these people and of course I listen to
2:17.3	their podcast. So this gentleman first came across peptides and correct me if I'm wrong,
2:23.1	Kyle. You know, you're a qualified nutritionist, naturopath, and I believe it was your mother's
2:28.7	diagnosis of cancer, correct, that got you going down a rabbit hole, and then later your father
