It made getting out of the vault with all 37 gold bars too easy, as I was able to go the long way around and get out of the vault before Elijah realised I was not in the vault. Trapped him in their, and left him with NOTHING. In a firefight? Too powerful! I used it with chemist and day tipper (Yes they do work on this perk) and I was able to move fast enough to avoid minigun fire. Best of all, it can be used repeatedly, every day, up to 10 doses, just like it says, non-addictive Turbo.
