New Discoveries
Discover How Fast You're Aging with ONE Score (& How to Boost It With the Agentis x Boundless Protocol) 🧬
I recently had Jimmy St. Louis on the podcast: a former NFL player, US Olympic rowing trials competitor, and four-time CrossFit regionals athlete who's now redefining the standard of care in longevity medicine. (You can check out the show and learn more about my trip to Arete Wellness in Nashville here.)
We talked through his path from a three-sport young athlete, through three ACL tears, into a spine surgery business that performed 100,000 procedures, and eventually into Agentis Longevity, the company he built by acquiring some of the best longevity clinics in the country and unifying them under one consistent set of protocols.
We also got into the Longevity Quotient, the five-test battery Agentis uses to score every new patient, and how we built a custom Agentis x Boundless protocol together.
A few of you reached out after the episode asking for more details about the protocol and how to get started, so here's the full breakdown:
- Getting Started: Take the Longevity Quotient (LQ) assessment, a $149 blood panel measuring 60+ biomarkers, and about a week later, get your 0–99 score showing how your body is aging relative to your peers, plus a full biomarker breakdown and a personalized plan from Agentis's clinical team.
- Foundation (Weeks 1–4): Reset inflammation, rebuild sleep architecture, and prime mitochondrial function.
- Optimization (Weeks 5–8): Layer in physician-guided interventions based on your labs, including peptides and targeted supplements where appropriate, to support recovery, cognition, hormones, and metabolism.
- Personalization (Weeks 9–12): Turn those changes into your new baseline, then retest to see exactly how your biomarkers moved.
Along the way, you get educational video modules, ongoing access to clinicians who can adjust your protocol as your data changes, and the option to complete your labs from home through concierge telemedicine or in person at Arete in Nashville.
There is no commitment to start, and the program is HSA/FSA eligible.

🎬 Watch the Official Boundless Trailer + Get Your Tickets for the LIVE Tour
For 20+ years, I've documented everything I've explored on how to optimize the human body to its greatest potential. Naturally, you might think a documentary about my life would be about biohacking, but Boundless: The Man Who Became Human tells a very different story.
This film is about what happens when the optimization framework I spent two decades constructing ran headlong into the things it could never measure. My marriage. My boys. My faith.
Featuring never-before-seen archive footage I debated even including, this film shows what it actually costs to chase the ceiling on human performance.
The official trailer is live now, and tickets for the Boundless Live tour are on sale for LA, Moscow (Idaho), NYC, and Austin, with more tour stops coming soon.
At Boundless Live, you'll join me and my family in the theater for the world premiere of the film, followed by a live recording of the Boundless Life podcast and an open audience Q&A. And if you choose the VIP experience, you'll also join us for the exclusive afterparty at an additional location, featuring upscale food and drinks (be sure to select “Add Event Extras” during checkout).
Tour Dates:
- Los Angeles (The Belasco): July 24
- Moscow, ID (Kenworthy Performing Arts Center): July 31
- New York City (The Bell House): August 6
- Austin (Emo's): August 20

This Week in Health & Performance: What the Latest Research Says
💥🏋️ Massage Gun Or Foam Roller? New research suggests both can improve your warm-up, but percussive massage therapy (your massage gun) appears to have a slight edge. While both improved balance and power, massage guns also enhanced strength, making them a better choice before training or competition. Previous research also suggests massage guns are ideal for pre-workout neuromuscular activation, while foam rolling may be better after exercise to reduce stiffness and speed recovery (full study here).
🏋️📏 Body Fat Percentage Beats BMI For Predicting Long-Term Health: A new study discovered that the most attractive body fat percentage for men is between 12–15%. It also found that body fat percentage is a better predictor of 15-year mortality risk in young adults than BMI. A move to using BF% rather than BMI may change how we measure body composition for risk stratification (read the full study here).
☕⚡ The Caffeine Sweet Spot May Be Lower Than You Think: How much caffeine do you actually need to boost performance without sabotaging your sleep or increasing anxiety? A new meta-analysis of 38 studies suggests that up to 3 mg/kg of body weight appears to deliver most of caffeine's performance-enhancing benefits while minimizing unwanted side effects like sleep disturbances, jitters, headaches, and anxiety (read the study).
🏃♂️🌅 Afternoon & Evening Workouts May Have A Slight Edge: The best time to exercise is the time you'll do it consistently. That said, a new meta-analysis suggests that regularly exercising in the afternoon or evening might provide modestly greater improvements in blood pressure and blood glucose compared to morning workouts. The differences weren't dramatic, but if you're looking to optimize cardiovascular and metabolic health, timing could provide a small additional advantage (full study here).
Key Takeaway: The biggest gains often come from optimizing the details. Choose the right recovery tool for the job, pay more attention to body composition than BMI alone, don't assume more caffeine equals better performance, and remember that small adjustments—like training later in the day—can provide an extra edge for long-term health and performance.

Product Of The Week
::: 🐶🌙 Help Your Pet Sleep Deeper (& Save $50) :::
Just like you, your pet benefits from a proper evening wind-down routine, especially after a high-output day, or during travel, in new environments, or even when there's a disruption to their normal routine.
That's one reason I've been trying the Hapbee Pets Pad. It's the same frequency-based technology I use in my HarmonIQ Neckband, only adapted specifically for pets.
Instead of relying on treats, oils, or supplements that have to be digested and metabolized, the Hapbee Pets Pad uses ultra-low-frequency signals designed to support a calmer, more relaxed state.
I run a dual digital protocol for my dogs right on their sleep pad.
Early in the evening, I use the app's Drift setting, which delivers the digital adenosine signal to help their bodies begin relaxing for the night. Then, at lights out, I switch it to Sleep, which delivers the digital melatonin frequency to help them sleep longer and recover more deeply.
Because it's frequency-based (and not a pill), there's no gut disruption or morning grogginess. In testing, it's been shown to help animals get up to twice as much deep sleep.
Give it a try with your own pets, and use my link to save $50.
