Standard Preservation (VM-1)
Our standard protocol using VM-1 cryoprotectant. Balances quality and cost for most families.
Give your pet the chance
they deserve with cryosleep.
What is cryosleep
Cryosleep is an ambulance ride to the future for your pet.
- 01
Stabilize
After clinical death, we take action. Medications, initial cooling, and cryoprotectant perfusion.
- 02
Transport
Following field surgery and initial cooling, we bring your pet to our long-term care facility.
- 03
Cooldown
At the facility, slow cooling gradually lowers temperature toward −196 °C to limit damage.
- 04
Cryosleep
Pets are secured in cryogenic dewars under liquid nitrogen until future treatment is possible.
- 05
Revival
When medicine advances far enough, the goal is to restore your pet and reunite you.
The alternatives are burial or cremation.
We offer a chance at life again.
Cryosleep procedure
We offer three procedure options.
Advanced Preservation (M22)
Our most advanced protocol using M22 cryoprotectant. Designed for the best possible preservation.
Basic Preservation
Traditional freezing without cryoprotectants. Most commonly used when vitrification is not possible. A lower-cost entry option.
Procedure pricing can be paid over time up until the preservation.

Cryoprotective agent quality
VM-1: proven vitrification protocol; widely used in cryobiology to minimize ice damage and support tissue viability; more affordable than M22.
M22: research-grade formulation; whole mammalian organs have been recovered from cryopreservation using M22-based protocols; best possible quality.
No cryoprotective agent - ice forms during freezing, with greater risk of cellular damage; lower quality preservation.
