You gain a non-addictive subdermal Turbo (chem) injector. This perk may be taken twice, with the second rank increasing the effect from 2 to 3 seconds and the uses per day from 5 to 10.— In-game description

Implant GRX is a perk in the Fallout: New Vegas add-on Old World Blues.


Implant GRX is a non-addictive drug with the same effects as Turbo: slowing down your surroundings to give you more time to act. It is accessed from your inventory in the Aid section of your Pip-Boy, with the supply replenished every 24 in-game hours. This perk can be taken twice, for enhanced effects:

  • Rank 1: it can be used 5 times a day, and lasts 2 (pre-Turbo) seconds per dose.
  • Rank 2: it can be used 10 times a day, and lasts 3 (pre-Turbo) seconds per dose.

The effects of multiple doses are cumulative.


  • The stated duration is for time before it's been slowed by the Turbo effect. As a result, the "real" duration is much longer.
  • With the Chemist and Day Tripper perks, rank 2 of Implant GRX will last 8 seconds in real time with each use. With Logan's Loophole, Chemist, and Day Tripper, the duration of each use (rank 1) is 16 seconds in real time.
    • Keep in mind that rank 2 of this perk cannot be taken with Logan's Loophole.
  • The Fast Times perk does not affect Implant GRX duration.
  • Like all chems, the duration of Implant GRX will stack with multiple doses. This can result in a lengthy duration of slow motion by consuming many doses at once (up to 80 seconds in real time using all 10 doses with GRX rank 2, Day Tripper and Chemist).
  • Uses of Implant GRX cannot be hotkeyed.
  • The effects of the implant are not cumulative with the chem Turbo. Doses of Turbo taken at the same time will be wasted.
