CI-VM-1

CI-VM-1 or VM-1 is a cryoprotectant that the Cryonics Institute uses in vitrification. "CI-VM-1" is a short for the Cryonics Institute vitrification mixture 1. The mixture was developed by the chemist and cryobiologist Yuri Pichugin who was the Director of Research at CI in 2001–2007.

The first person vitrified by CI with CI-VM-1 was CI-69, a 79-year-old female who was cryopreserved in August 2005. Previously, CI had tested CI-VM-1 with two dogs, in August 2004 and February 2005.
