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
The amount of health restored by one stimpak is between 30–90 HP (36–108 HP with the Fast Metabolism perk), and dependent on the level of the medicine skill. It is equivalent to the expression $$30 + 0.6M$$ (with Fast Metabolism, $$(30 + 0.6M) \times 1.2$$ or $$36 + 0.72M$$), where $$M$$ is the level of the medicine skill.

In contrast to previous games, stimpaks in Fallout 3 can also be used to heal crippled limbs. When used on a limb it heals a relatively high amount of damage on the limb, but little on the whole body. Conversely, when used on the whole body, a relatively high amount of damage on the whole body is healed, but the limbs are healed only slightly. 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 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 chooses to play in Hardcore Mode, stimpaks will heal over time (versus instantly) and will not heal crippled limbs. Limbs can only be healed by a doctor, with the use of Hydra or by a doctor's bag. Stimpack sickness can occur if player uses too many (super)stimpacks, this results in -1 Strength and -1 Agility.

Stimpaks can also be created by using Broc flower, empty syringe and Xander root with a Science skill of 70 at a workbench.

The base ID is equal to the ID used in Fallout 3.
