Stimpak

Stimpak, or Stimulation Delivery Package, is a type of hand-held medication used for healing the body. This item consists of a syringe for containing and delivering the medication and a gauge for measuring the status of the stimpak's contents. When the medicine is injected, it provides immediate healing of the body's minor wounds. Superior versions are super stimpak and ultra stimpak.

Health dispensers in the Operation: Anchorage add-on, manufactured by Lee Rapid Pharmaceuticals, have an identical delivery method, which hints that stimpaks are also a product of the company.

Fallout, Fallout 2 and Fallout Tactics
In Fallout, Fallout 2 and Fallout Tactics, stimpaks only restore hit points, crippled limbs have to be restored with use of the doctor skill. They are plentiful and easy to come by in more civilized areas, although on the outskirts of post nuclear civilization (such as Klamath or Den in Fallout 2), they can be quite rare and fetch high prices.

In Fallout 2, Myron can make these if you give him the proper ingredients:
 * Empty hypodermic
 * Xander root
 * Broc flower

Fallout 3
Stimpak regeneration is based on medicine and can be calculated with 30 + (medicine x .6) or 36 + (medicine x .72) with the Fast Metabolism perk. This means that they have a base of +30 HP and up to +90 HP at 100 medicine.

Unlike previous games, in Fallout 3 they can also be used on crippled limbs to heal them. When used on a limb it heals most of the damage on the limb but very little on the whole body's HP, and when used on the whole body, the whole body's HP is healed, but limbs are healed very little. Because of this, the use of stimpaks is rather tactical. The alternative ways of healing limb damage are: sleeping in a bed, clinics, the Rad Regeneration perk from the Wasteland Survival Guide quest, or using the my first infirmary.

Stimpaks are often found accompanying other hand-held medical equipment on compartment trays.

Fallout: New Vegas
Stimpaks function much the same as in Fallout 3, with one exception. If the player choses to play in Hardcore Mode, stimpaks will heal over time (versus instantly) and will not repair crippled limbs; they can only be healed by a doctor or a doctor's bag.

Stimpaks can also be created by using Broc flower ,empty syringe and Xander root at a workbench.

Appearances
Stimpaks appear in Fallout, Fallout 2, Fallout 3, Fallout Tactics, Fallout: Brotherhood of Steel, Fallout: New Vegas, the canceled Van Buren, and the canceled Fallout: Brotherhood of Steel 2.
