We provide human cryopreservation, using extremely low temperatures to stop biological processes in the body. Patients are cryopreserved in the expectation that future technology may be able to revive them and treat their underlying cause of death.
We’ve improved all aspects of human cryopreservation, including patient storage, by building a secure long-term facility in Switzerland where patients are stored indefinitely until revival may one day be possible.
Membership includes cost savings on cryopreservation costs and access to our community and resources. Use code BAY10 for 10% off when you’re ready. Start by learning how cryopreservation actually works on our site.
