Stim Reaper Pre Workout is the latest pre workout from Killer Labz and their brand refresh.
Stim Reaper is a stim junkie pre workout. That being said, its just a stimulant pre workout like Flame Pre Workout and Psychotic Pre Workout. So there is no pump support here like Citrulline, Nitrosigine, etc.
You will need to stack this with a stim free pre workout like Compound Pump, BloodSport if you want some pumps.
