Killer Labz HIGH STIM Reaper Pre-Workout (30 servings)

Killer Labz Stim Reaper packs a total of six ingredients, four of which are stimulants included to increase energy and enhance mental focus. The other two features in the product are more for performance and endurance, although the main focus of the supplement is still its set of hard-hitting stimulants.

Making up a full serving of Stim Reaper are the only non-stimulants in the formula with beta-alanine and taurine dosed at 3g and 1g per serving. The rest of the supplement’s lineup is made up of 2mg of rauwolfia vomitoria, 250mg of eria jarensis, 100mg of j regia, and of course caffeine, dosed at a strong 400mg.
