Plan Z

Plan Z is a short term physical enhancement drug that allows the user to keep on going despite serious injury. However it's a terrible thing to take - your supercharged physical actions are probably going to cause more damage to your body and you become hyper-aware of every injury. You get five minutes of being a juggernaut that doesn’t feel pain, ignores sedatives, and more. Then when it wears off wears off you’re going to be on the floor and in need of medical attention.
Plan Z is sometimes called the Zombie or Beserker drug.
