Ultrajet

Ultrajet is a stronger version of the drug Jet.

Ultrajet is a concoction of Jet, Sugar Bombs, and Abraxo Cleaner, synthesized by the ghoul Murphy. Ultrajet offers 40 action points compared to the 30 from regular Jet, and their use can be 'stacked'. As a separate drug, Ultrajet addicts won't get their fix if they use regular Jet, or vice versa.

Locations
A Ghoul named Murphy in Northwest Seneca Station will sell you one Ultrajet for every 8 boxes of Sugar Bombs.

Appearances
Ultrajet appears in Fallout 3.

Max AP
Combine this with:
 * Jet
 * Nuka Cola Quantum
 * Nukalurk Meat
 * Ledoux's Hockey Mask
 * Mississippi Quantum Pie
 * The Action Boy/Girl perk and a high Agility

With all of these you can get an amazing amount of AP, enough to fire the Experimental MIRV about 2-3 times in VATS
