Ultrajet

Ultrajet is a stronger version of the drug Jet.

Ultrajet may be a combination of Jet, Sugar Bombs, and Abraxo Cleaner, since the third ingredient is lying around Murphy's lab in abundance, though this is unsupported.

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.
