The Moment It's For

Five cards. Five moments.

Tight calf at mile 18.

You felt it at 14. By 18 it was locking. Apply at the hotel. Twenty minutes. The fiber that's been starving for oxygen finally gets it.

Swollen knuckle between rounds.

Boxing. Grappling. Tennis elbow that shows up after a doubles weekend. Targeted CO₂ on the joint, passive recovery while you sort your schedule.

Hamstring twinge pre-match.

You have 90 minutes. The warm-up is flagging it. Thin layer on the belly of the muscle. Circulation opens. You get to the kickoff.

Neck flare at 10 PM.

You slept weird two nights in a row. The heating pad is helping but not moving it. CO₂ Renew at the base of the skull. Rinse before bed.

Post-facial / post-peel.

Travel schedules and aesthetic schedules rarely line up. 10mL is one post-procedure soothing session. Shelf-stable in a carry-on.

10mL × 5 tubes

Fits a Dopp kit or jersey pocket

TSA 3-1-1 compliant

No device, no prep, no cooler

The Bohr Effect in 60 Seconds

Your blood already has the oxygen. The paste tells it where to go.

When CO₂ in local tissue rises, hemoglobin lets go of the oxygen it's been carrying. That's the Bohr Effect — the mechanism your body uses every second to send oxygen to working muscle.

CO2 Renew concentrates and externally delivers that signal. Apply it. Wait twenty minutes. Rinse. Tissue oxygenation you can't get from a roller, a massage gun, or another cream.

Questions

On the road — answered.

Yes. Each tube is 10mL — well under the 3.4 oz / 100mL per-container TSA liquid limit. Carry them in your 3-1-1 bag. For international, check your destination's liquid rules.
Room temperature. Shelf-stable. No cooler, no ice pack. A hotel drawer or gym-bag side pocket is fine.
Each 10mL tube delivers 2–3 targeted applications. Don't dip a dirty finger; dispense onto clean skin or a clean applicator. Once opened, use the tube inside 90 days.
Thin, even layer on clean, dry skin over the target area. Wait 20 minutes. Warm water rinse. That's it. No heating pad, no wrap, no device.
Unopened: the printed expiry date (typically 12+ months from production). Opened: 90 days for optimal potency.
Common protocol: apply the night before, rinse, rest. Same-day use is safe — apply, wait 20 minutes, rinse, warm up as usual. Test your own timing in training first.
Bring the fifth home. It doesn't care.
