With the Fast Metabolism perk, you gain a 20% Health bonus when using Stimpaks.”
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.
