Stimpak (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.
A stimpak heals the player over a short period when used. The amount of health restored by one stimpak is 104 HP (124, 145, 166, 187, 208 HP depending of each rank of the First-Aidskill - skill function as perks do in the other games).
