From Citizen Sleeper Wiki
The Stabilizer is an item players encounter throughout gameplay of Citizen Sleeper.
Description[edit]
The Stabilizer is one of Essen-Arp's corporate pharmaceuticals which can be used to slow the degeneration of a Sleeper host and thus, can be useful in aiding the regeneration of a players condition.
The first Stabilizer will be given to players free from Sabine at the Hab Block in the Bright Market district. However, there is a three cycle window between meeting Sabine and getting the first stabilizer, so players must ensure that their condition can last three cycles without relying on Sabine's gift. Moving forward, each Stabilizer will come at a cost of 100 cryo but can still be bought from the Hab Block
