My Favorite Biohacking Device

Happy Friday!

I just dropped a brand-new video on the device that has quietly become my favorite recovery and biohacking tool in my entire house.

It’s called the Bimini NanoJet oxygen therapy system.

This isn’t a peptide, it’s not a supplement, and this email is definitely not a paid ad.

It’s a little machine that sits beside my bathtub, turns my tub into an oxygen storm of nanobubbles, and has done more for my recovery, sleep, and skin than almost anything I’ve tried in the last few years.

If you’ve ever wondered, “Okay Hunter, but what’s your actual #1 recovery tool?” this is it.

In the video, I walk through the tech, the data, and my real-world results after months of using it several times per week.

Today I wanted to put that into email form so you can see why I put this thing right up there with medical-grade red light therapy (and honestly, for me, maybe even a little above it).

How I Stumbled Into the “Oxygen Bath”

About a year ago, at A4M in Vegas, I was wandering around the expo floor.

I walked past this booth with a giant photo of Kyrie Irving and a tub on display, and my curiosity kicked in.

I start talking to the team, and they explain that the technology is an oxygen perfusion system.

It pumps ultra-fine oxygen nanobubbles into the water, and you literally absorb oxygen through your skin while you soak.

I thought it was cool, but I didn’t jump immediately.

The system was around $10K at the time, obviously not a casual purchase.

Over the next few months, I kept hearing about it from pro athletes, trainers, and some of the most respected people in the performance world.

Eventually, I bit the bullet, ordered one, and set it up next to my home bathtub.

Now, several months later, I can say without exaggeration that this is the best at-home recovery device I own.

For context, I’m not someone who fills my house with random gadgets.

I’m pretty skeptical about most biohacking toys.

But the Bimini NanoJet has earned its keep.

What it Does

Here’s the simplest way to think about it:

When you sit in that bath, especially if the water is warm enough to open your pores, those nanobubbles penetrate the skin, dissolve, and deliver oxygen directly to your epidermis and the soft tissue beneath.

Your skin basically becomes a giant respiratory membrane.

No mask, no chamber, no pressure changes.

Just you, hot water, and an invisible cloud of oxygen feeding your muscles and skin from the outside in.

Compared to hyperbaric oxygen, which pushes oxygen into your blood via the lungs under pressure, Bimini delivers oxygen through the skin.

For things like sore legs, plantar fasciitis, or beat-up muscles after training, this local oxygen flood is incredibly powerful.

Real-World Results

The first thing I noticed was HRV and sleep.

Before Bimini, I had never seen an HRV over 100 on my Oura.

After a couple of weeks of consistently doing 30-minute sessions at night, I started hitting 90s and low 100s regularly, and my sleep scores were in the 90s as well.

Same training, same diet, same peptides.

Every time I go a few days without using it (travel, craziness, etc.) and then get back in, I see the same pattern.

HRV bumps up, deep sleep goes up, and I wake up feeling more recovered.

On the recovery side, this has been huge for soreness and soft tissue.

I’ll do heavy training and then a Bimini session that night, and the next day, my legs feel like I took 30–40% less damage.

Taylor has been dealing with plantar fasciitis, and every time she gets in the tub, she comes out saying, “My feet feel so much better.”

It’s become part of her lower-body recovery toolkit.

And then there’s skin. I’ve been open about dealing with acne, especially on my back, compounded by training, sweating, sauna, and not always being able to shower immediately.

Since using the Bimini tub consistently, my back skin is the best it’s been in years.

Oxygen is a massive player in collagen production, tissue repair, and skin health, and you can see that show up over weeks and months of use. 

It feels like my entire system is less inflamed, better oxygenated, and more resilient.

What the Science Says

You know I’m not happy with anecdotes.

I want to see what the data says.

Here’s a quick look (links at the bottom).

Bimini muscle oxygenation study – In their white paper, Carfagno and colleagues placed athletes in a NanoJet oxygen bath and measured muscle oxygen saturation (SMO₂) with near-infrared sensors. Within 5–20 minutes, muscle oxygen jumped from ~50% to over 90% – basically doubling the oxygen saturation in the muscles soaked in the tub. 

Rice University performance study – Over six months and 100+ athletes, Rice sports medicine used the NanoJet for injury rehab and post-workout recovery. They saw measurable improvements in motor coordination and reaction time in about 46% of sessions, with benefits lasting 1–2 hours after the bath and no adverse events across hundreds of uses. 

Burn wound healing (UC Irvine) – In a 2019 study on rats with full-thickness burns, wounds treated with oxygen micro/nanobubbles healed significantly faster and more completely than controls. The nanobubble group hit ~85% healing vs ~52% in the control group, with better collagen organization and tissue quality. 

Transdermal delivery study (Nanomaterials, 2023) – Researchers showed that water containing oxygen nanobubbles pushed active ingredients through a skin-mimicking membrane six times faster than a standard formulation (30 minutes vs 3 hours). The nanobubbles gently “loosened” the outer skin layer without irritation, acting as a safe penetration enhancer. 

Oxygen nanobubble hydrogel (ACS, 2023) – A hydrogel dressing loaded with oxygen nanobubbles significantly accelerated wound healing in diabetic mice compared to standard dressings, highlighting how nanobubbles can hold and release O₂ directly into tissue. 

All of these line up with what we feel subjectively in the tub.

More oxygen reaching tissues that are usually slightly starved, clearer healing signals, and less inflammation.

Bimini vs. Hyperbaric

A lot of people ask, “So is this just a poor man’s hyperbaric?”

Not exactly. It’s different, and in some ways more practical for day-to-day life.

Hyperbaric oxygen therapy (HBOT) uses a sealed, pressurized chamber and near-100% oxygen to massively increase dissolved oxygen in your blood via your lungs.

It’s incredible for certain conditions and is the gold standard for things like decompression sickness and specific wound types. But it’s also:

Bimini keeps you at normal atmospheric pressure.

It uses water as the delivery medium and your skin as the interface.

For local soft tissue, skin, and recovery applications, that’s actually a huge advantage.

It’s more like having a hyper-oxygenated spa session three to four times per week in your own bathroom, which is exactly how I use it.

Bimini also makes it very clear that this is a non-medical device and they’re not making disease-treatment claims

It’s a wellness and recovery tool, not a replacement for proper medical care. 

If You’re Thinking About Getting One

Is this for everyone? No.

I’m very aware that a $10K-ish device is not an impulse buy. If you’re still working on dialing in sleep, diet, training, and basic bloodwork, that’s the first step. But if you’re someone who:

…then the Bimini NanoJet is absolutely something I’d put on your radar.

Because I’ve been using it and talking with their team, they gave me a code for my community.

If you decide to pick one up, you can get $500 off your purchase by using the code HUNTERW at checkout on the Bimini site.

You can check out the different models here. I have the Nanojet Eco (Eco for home, Pro/All-In for facilities).

If you watch the video and read through some of the papers below, you’ll see why I’m so bullish on oxygen nanobubble tech as one of the next big frontiers in recovery and regenerative medicine.
