Psycho (Fallout: New Vegas)

Psycho, also called "angry juice", is a consumable item in Fallout: New Vegas.

Characteristics
Psycho is a chem that, for all intents and purposes, makes the injected a psychopath. They become more agile and aggressive, increasing the output of damage from any of the user's physical talents or weapons. Overdosing on Psycho numbs the senses and leaves the body physically weaker, and can be lethal in extreme cases.

Psycho is also a primary ingredient in slasher - which increases both damage and damage resistance, but has a much shorter duration.
