New Discoveries
Reversing Aging with Hyperbaric Chambers? *Here’s* How Soft and Hard Shell Systems Go Head-to-Head in the Race to Turn Back Time ⏳
If you’ve been following me for a while, you already know I’m a huge fan of hyperbaric oxygen therapy (HBOT) for recovery, brain performance, and longevity.
My friend Dr. Jason Sonners, one of the most knowledgeable guys I know in the HBOT space, recently shared some fascinating research comparing soft shell (1.3 ATA) and hard shell (2.0 ATA) chambers, and the results are worth paying attention to.
According to Jason's research (you can discover more about that here), both types of HBOT helped lower inflammation by modulating cytokines, but in different ways.
Soft-shell chambers had a stronger effect on TNF-α and IL-6—key drivers of autoimmune conditions and chronic inflammation—while hard-shell chambers were more effective at targeting myeloperoxidase, which may make them better suited for heart-related inflammation or post-viral recovery (like long COVID).
What’s even cooler is that participants using either pressure saw notable cognitive improvements, especially in memory recall, though the higher-pressure group gained a slight edge.
Both pressure levels helped turn back the clock on biological aging, but through different mechanisms.
The mild chamber seemed to rejuvenate early DNA aging markers faster, while the higher-pressure setup worked more deeply on the second-generation “clocks” linked to disease prevention and longevity, just taking a little longer to show results.
Personally, for the best results, I like to stack my HBOT sessions with intermittent fasting, nitric oxide boosters, or methylene blue to amplify oxygen utilization. Just avoid high-dose antioxidants (like glutathione) right before your session since they can blunt the beneficial hormetic response.
What type of HBOT do I use at home? A soft-shell model that Jason himself recommended, the Vitaeris320 by HBOT USA. It’s easy to use, incredibly effective, and a powerful way to recharge your body and brain from the inside out.
You can learn more about Dr. Sonners’ work and equipment options here.
And if you're interested in diving into the benefits and mechanisms of HBOT in more depth—including why I chose the Vitaeris320 by HBOT USA and the details about how I set up my own softshell HBOT unit for my home, which I've been climbing into just about every day for reading and napping—you can check out these resources:

Family Time Just Got A Lot More Fun (& Gassier)—Introducing Fart of War, the Hilarious Card Game My Twin Sons Dreamed Up! 💨 🎉
In a world where “family time” too often means everyone staring at their own screen, it’s getting harder to laugh together, talk face-to-face, and make real memories without a device in hand.
Our family game nights became some of our favorite memories, a time to unplug, joke around, and just be together.
Inspired by our game nights, my twin sons came up with Fart of War—a wild, witty card game that turned our living room into a battlefield of laughter (and, well… questionable smells).
What started as a family project to spend more time together quickly became a creative mission to build something fun from scratch, and now my sons have officially launched Fart of War on Kickstarter, which is LIVE here.
If you’re ready to back the most side-splittingly funny card game ever made—and support two young entrepreneurs on a mission to bring families together for hilarious, screen-free fun—this is your moment.
Most Protein Bars Are Junk Food in Disguise… So I Created *This* Delicious Fix ⚡🧠🍫
I’ve been working on something behind the scenes that is about to change the way you fuel your body and brain, and totally transform the protein and energy bar industry.
As you probably already know, most protein bars (and energy bars in general) are full of junk—they spike your blood sugar, wreck your gut, leave you hungry an hour later, and they taste like cardboard.
Sure, you get protein, but a lot of crap along with it, and not really much appetite satiation or noticeable cognitive upticks at all. 👎
So, based on what I know about the intriguing science of fueling with ketones, I decided to build something totally different…
👉 Meet Boundless Bar—the world’s FIRST ketone-powered protein bar.
Unlike sugar, which burns fast and leads to energy crashes, Boundless Bar is built around goBHB®, the gold standard in exogenous ketones, helping you:
- Fuel your workouts with ketone-backed energy that sustains physical and mental performance for hours on end.
- Stay sharp at work with enhanced mental clarity, memory recall, and focus.
- Support recovery and repair with collagen for muscles, joints, skin, and connective tissue.
- Curb cravings with satisfying protein and ketone-driven appetite control.
- Optimize your aging with ingredients that promote cellular resilience and whole-body vitality.
Every Boundless Bar includes:
🍖 18g of hydrolyzed collagen protein to support muscle recovery, joint health, hair, and skin.
🔥 260–270 calories (depending on the flavor) with healthy fats from cashew butter and cocoa butter to keep you fueled.
⚡ goBHB® ketones for rapid, stable energy without stimulants, sugar crashes, or jitters.
🚫 Zero seed oils, gluten, dairy, or soy for guilt-free, gut-friendly nutrition.
🍯 Honey and monk fruit for a naturally balanced, indulgent flavor.
And forget the chalky taste of typical protein bars or the nasty aftertaste of most ketone products—with Boundless, you can choose from two delicious flavors (more to come, including Blueberry Pie and Chocolate Chip!):
- 🍯 Cinnamon Roll Bar (just 270 cal): Blends real cinnamon spice with creamy cashew butter and a touch of honey and monk fruit, delivering the taste of a cinnamon roll with the fuel of a performance product.
- 🍰 Vanilla Cheesecake Bar (just 260 cal): Combines smooth vanilla with a rich, creamy texture, giving you the indulgence of cheesecake in your pocket—without the sugar crash.
Both flavors make it easy to stay on track while enjoying every bite, providing you with clean fuel and a smarter, all-day ally to p
ower your brain, body, and future.
Normally, to achieve ketosis, you have to suck down a bitter drink, fast for days, or engage in strict carb restriction. But now you can quite literally eat your way into ketosis with a delicious low-calorie, high-protein bar that satisfies your appetite and powers your day for hours on end.

Product Of The Week
::: Save 15% on the Sleep-Promoting Mineral That Transforms Recovery 😴 :::
If you’re setting ambitious weight-loss goals, there’s one critical factor you might be overlooking: your sleep quality.
A compelling new study revealed something wild: poor sleep reduced fat loss by 55% in dieters, even when calorie intake was identical. Worse yet, it increased muscle loss by 60%.
Think about that: two people following the exact same diet, but the one sleeping less lost half the fat and more lean muscle.
What's the connection between poor sleep and trouble losing weight?
- Poor sleep spikes hunger hormones (like ghrelin).
- Sleep deprivation crushes fat oxidation (your body's ability to burn and lose fat.
- Inconsistent rest increases cortisol, making your body store more fat.
The missing link? Magnesium.
It’s one of the most underrated minerals for optimizing recovery and deep, restorative sleep—but only if you’re getting the right forms.
That’s why I recommend Magnesium Breakthrough, the only magnesium supplement that combines all 7 essential forms, designed to:
- Support calm and faster sleep onset.
- Improve sleep quality and recovery.
- Support a healthy stress response and muscle function.
Make this the year you finally achieve your goals, both in and out of the gym.
You can receive 15% off Magnesium Breakthrough here with code BEN15.
