Adrenaline Powder (3.5e Equipment)
From D&D Wiki
This crimson powder momentarily increases the adrenaline output of anyone who ingests it (usually either nasally or by rubbing the powder on their gums). The powder gives its user a +2 alchemical bonus to Strength for 2d4 rounds, then makes the character fatigued for (10 - Con modifier) rounds.
A pouch of adrenaline powder costs 250 gp.
