Field Might Stim

Field Might Stims are basic stimpacks.

Use
Upon activation of a Field Might Stim, a character's Strength attribute is increased by 24 points for the next 60 minutes. Each character can only benefit from a single stimpack at any one time; if a new stimpack is activated before the duration of another has expired, the effect of the previous stimpack will be replaced by the effect of the most recently used item.

Source
Field Might Stims can be bought from level appropriate stimulant and medical droid vendors. They can also be gathered as random world item drops from level appropriate chests.
