Supp facts Killer Labz Stim Reaper is a pure-stimulant pre-workout - 400mg caffeine, eria jarensis, and rauwolfia vomitoria (alpha yohimbine), with no citrulline or other pump ingredients at all.
Pre-WorkoutThis is deliberately a stimulant-only formula - the brand skipped pump ingredients like citrulline or Nitrosigine entirely, so it's built purely for energy, focus, and a fat-burning edge rather than vascularity. At 400mg caffeine plus eria jarensis and rauwolfia vomitoria (alpha yohimbine, related to standard yohimbine and used similarly for fat mobilization and intensity), it's a serious stimulant load meant for experienced users, and it's worth stacking with a separate stim-free pump product for a customer who also wants that side covered. Given the caffeine dose, it's best reserved for earlier in the day to avoid disrupting sleep.
