Ultrajet

Ultrajet is a stronger version of the drug known as Jet.

Locations
A ghoul named Murphy will create Ultrajet for you. He says he has two of the three ingredients needed to make it. The last ingredient is Sugar Bombs. He will pay you 15 caps for each box of Sugar Bombs that you bring him, and an extra 15 caps with persuasion.

Note: About 10 boxes of Sugar Bombs can be found in a trailer at Everglow National Compound, which is northeast of Little Lamplight. Two more boxes can be found under the register in the Super Duper Mart just about the entrance to the subway where Murphy lives. About 10 more can be found in Mama Dolce's food factory, which is east of Arlington Cemetery South, and is also a good place to stock up on Chinese Assault Rifles. You can find at least 5-10 boxes in the Citadel in the mess hall. Seems like the Brotherhood loves their cereal.

Appearances
Ultrajet appears in Fallout 3.
