For a cross-game overview of this perk, see Fast Metabolism.
With the Fast Metabolism perk, the player character gains a 20% bonus when using stimpaks. In Hardcore mode, the multiplier increases the amount of healing per second making stimpaks an even better in-combat healing option. Players outside of Hardcore mode may be better served by simply applying multiple stimpaks from their Pip-Boy rather than investing in the perk.
