If you get this perk, however, you should plan to exploit it fully-get both ranks, and get the ‘Chemist’ perk. Turbo is a pretty handy chem, and although you could simply carry some around, it’s much more convenient to have this perk. Implant GRX is not a bad perk, it just has bad interface. 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. You gain a non-addictive subdermal Turbo (chem) injector.
