Super stimpak

Super Stimpak is a chem in Fallout, Fallout 2 and Fallout Tactics: Brotherhood of Steel. A superior version of the regular Stimpak.

An advanced healing chem. Very powerful. Superstims will cause a small amount of damage after a period of time due to the powerful nature of the chemicals used.

Myron can make these for you if you give him the proper ingredients.

Superstims also have a nefarious purpose. They can be used to assassinate friendly NPC's in populated areas. Having the Awareness perk helps, as you can see how much health the target has. Simply divide his or her current health by 9 then round up. The number you reach is how many Super Stims you should use to take your victim out. After juicing them (stick the Stims in one of your weapon slots to make this easier) wait 2 minutes and they should keel over.
