Contact is the load. Recovery is the multiplier.
CO2 therapy triggers the Bohr Effect — releasing oxygen from hemoglobin into the exact tissue that just took the hit. Joint support. Soft-tissue repair. Off-season rebuild.
The paste lives on the field sideline and in the locker. The Flex Kit lives at home or in the team facility. Together, they cover every recovery window the sport creates.

Facility-grade recovery
Built for contact sport
A career's worth of collision doesn't forget.
Football is joint pounding plus contact energy — every single rep.
A lineman absorbs impact loads that stack across hundreds of plays a week. A defensive back redirects force through knees, ankles, and hips at speeds no other sport demands. Even on a "clean" day, tissue is carrying micro-damage that will need to repair before next practice — or it compounds into an injury on Sunday.
The recovery cost doesn't show up on a stat sheet. It shows up in off-season knee surgeries, in the third game of a three-game stretch, in career length.
CO2 therapy works directly on the physiology that determines whether tissue actually heals in the window between reps: microvascular function, tissue oxygenation, and the body's natural repair signaling.
The science.
Your blood already carries the oxygen. CO2 is what makes it land.
Oxygen alone doesn't repair tissue. The Bohr Effect — the physiological mechanism where concentrated CO2 causes hemoglobin to release oxygen into the tissue beneath it — is what moves oxygen out of your bloodstream and into a bruised quad, a torn-up ankle capsule, a hot-spot knee.
AEIR's transdermal CO2 therapy concentrates that signal. The paste does it locally on a target zone. The Flex Kit does it systemically — shoulders to toes in 30 minutes. Same mechanism, different dose.

Field-side and locker-room ready.
Targeted acute relief. Daily ritual. Pre-camp tissue prep. $99 for five 10ml tubes.
Sideline and locker-room application
Paste applied to a bruised quad, a hammered calf, a contact-sore shoulder. Covered with plastic wrap for 20–30 minutes. Localized Bohr Effect right where the hit landed — no equipment, nothing to plug in.
Daily ritual for joints
Knees, ankles, low back — the zones that carry cumulative load. Nightly paste application becomes a low-friction habit; the compounding benefit over a 16-week season is the point.
Pre-camp and pre-practice tissue prep
The morning of camp open. The morning of a heavy install. Apply to known vulnerable zones; enter practice with tissue already warm, vasodilated, and oxygenated.
The AEIR Full-Body Flex Kit
For the nights you owe your body.
30 minutes, systemic recovery, no stress position. $2,799 for the extra-large-zipper suit, filling kit, and hydrogel.
Systemic, not only spot-treatment
Where paste targets a hot zone, the suit surrounds shoulders to toes. Every tissue bed gets CO2 exposure — vasodilation and Bohr-Effect-driven oxygen delivery, head to foot.
30-minute passive session
Zip in. Vacuum. Let the hydrogel activate the CO2. Watch film, eat dinner, talk to your PT. No strain, no effort. Professional-grade recovery while you sit still.
Facility-grade at home
The same kit used inside team training facilities and performance partner sites is available for individual athletes. No equipment rentals, no appointment windows, no downtime.
Athlete feature — Brian Kula, NFL advocate.
When you've hit every recovery tool in the building — and then you find the one that works on the cell.
Brian Kula has spent his career inside elite football performance environments. He's used every recovery modality a professional program can buy. What brought him to AEIR wasn't novelty — it was the mechanism.
Most recovery tools work on sensation. They feel like recovery. The Flex Kit works on whether oxygen is actually getting to tissue that's damaged — the Bohr Effect, delivered transdermally, systemically, in 30 minutes. Kula's story isn't dramatic. It's cumulative: fewer bad mornings, faster turnarounds, better training weeks.
That's the story AEIR cares about. Not a single dramatic recovery, but a tool that quietly shifts the baseline of every week of training.

Partnership spotlight
Integrated into one of the most respected performance training organizations in pro sport.
AEIR partners with Mike Barwis and Barwis Methods — a program that's trained the physical foundation of careers across the NFL and beyond. On the Barwis podcast, AEIR's founder Ross Schilling walked through the mechanism, the clinical work, and why CO2 delivery — not oxygen supply — is the variable that actually moves recovery outcomes.
The conversation is a plain-language entry point to the science for anyone curious about what distinguishes AEIR from every other recovery device on the market.

College football
Adopted at the top of college football.
AEIR CO2 therapy is in use within top NCAA football programs — including partnerships scaling across a premier program. Performance staff integrate the Flex Kit into post-practice and post-game recovery blocks; paste is deployed in individual player care.
No program logos or uniforms are displayed on this page by AEIR policy.
"When I sit across from a head of performance for an elite football program, I don't explain AEIR as a device. I explain it as physiology they already know — the Bohr Effect — finally given a form that can scale across a roster."
Paste as the daily companion. Suit as the elite anchor.
The football recovery protocol.
Every phase has a touchpoint.
Joint rehab
Paste, daily
Knees, shoulders, ankles. Areas carrying offseason surgical history or cumulative wear. Paste nightly. Build the microvascular environment repair actually uses.
Systemic reset
Flex Kit 3× week
Full-body sessions ramp the system — not only the areas you're rebuilding, but the compensation chains upstream and downstream.
Training ramp
Pair with lift days
Suit same day as heavy lift blocks. Paste the following morning on the areas that reported hardest.
Camp countdown
30–60 day window
Shift paste from rehab zones to performance zones. Pre-habilitate the tissue you'll ask most of at camp open.
Two-a-days reality
Paste between sessions
Between morning and afternoon practice, apply paste to whichever zone is loudest. 20–30 minutes under wrap during film or meal.
Suit each night
Full systemic reset
Once per day through the first two weeks of camp. Passive 30-minute session. Your body rebuilds while you sleep.
Pre-practice
Paste on known zones
Fifteen to twenty minutes before warmup. Vasodilation and tissue warmth on day one of camp and every day after.
Fatigue indicators
Listen to the data
If HRV, sleep, or subjective readiness dips — pull in an extra paste session at midday.
Game day prep
Paste morning-of
Target zones — the quads for a running back, shoulders and low back for a lineman, hamstrings for a receiver. Tissue warm and oxygenated at warmup.
Post-game
Flex Kit within 24 hours
Sunday-night or Monday-morning Flex Kit session. Systemic flush. Paste on the single worst zone the following morning.
Travel
Paste on the road
Five 10ml tubes in the bag. Hotel application after travel or after practice. Suit waits for home.
Bye week
Double the reset
Two suit sessions and daily paste through bye. Compound the window. Return to practice with a deeper baseline than you left.
Surgical recovery
Cleared for therapy
Once your surgical team clears therapy, CO2 application supports the microvascular environment tissue repair requires. Research in transcutaneous CO2 and fracture models shows accelerated bone healing with calibrated dosage.
Chronic joint care
Long-term paste ritual
For post-career athletes, paste becomes an anti-wear daily. Hands, knees, ankles, low back. The mechanism is the same as in-season; the timeline stretches.
Quality of life
Suit for systemic support
Full-body Flex Kit one to two times weekly. Sleep quality, joint stiffness, next-day readiness.
Pay it forward
Son, daughter, kid you train
Paste is safe across ages. Many post-career athletes introduce it into their kids' recovery routines — the compounding habit starts early.
