The I2-LP Syringe (Injury Infection Liquid Pharmacon Syringe) is a consumable item that can be found throughout the Lab environment in resource containers as well as on shelves or desks. Syringes come in two different forms, a yellow one called 'IIx' and a red one called 'I2-LP'.
Red syringes grant 10-12 health upon usage, at the cost of a small amount of infection.
A red syringe can potentially save your life if used when you are about to be downed. It heals a small amount of health at the cost of some infection.
