My apologies for the necro (it's just the Domain of Black, no shedim drek, I swear!) but here's my first foray into cooking drugs:
Name: Flash
Formula: Warrior + Stonewall 1 + Strike 2 + Duration Enhancer 2
Vector: ingestion
Speed: 3 combat turns
Duration: 10x3d6 minutes
Addiction type: physiological
Effect: +3 Agility
Crash: 2S unresisted
Addiction Rating: 8
Addiction Threshold: 4
Availability: 9R
Cost: 225Y per dose
What can I say, I hate, hate, HATE side effects.
EDIT: Once i've wrote it down, I realized that the duration wasn't long enough - I was going for something to take BEFORE the action - so I've added additional duration enhancer.
