Insane Labz Redrum
299mg caffeine. Nitric oxide support. Razor-sharp focus. 25 servings of hard-hitting pre-workout intensity built for athletes who train without limits.
299mg Caffeine
A full-strength stimulant dose from multiple sources to fuel high-output training from the first rep to the last.
Nitric Oxide Support
Includes agmatine sulfate and other pump-support ingredients to help promote blood flow and muscle fullness during training.
Laser Focus
Formulated to sharpen mental drive and concentration so you stay locked in through every demanding set.
Beta-Alanine Endurance
Supports muscular endurance and helps you push through high-rep sets and extended training sessions.
25 Servings
A full container of pre-workout fuel designed for consistent, high-intensity training over weeks of hard work.
Advanced Formula
Goes beyond basic caffeine with taurine, niacin, B12, and a full stack of performance-support compounds.
What Makes It Different
- Multi-Source Caffeine Stack: 299mg from combined sources delivers a more sustained energy curve than single-source caffeine products.
- Pump + Stimulant Combo: Most high-stim pre-workouts skip pump ingredients — Redrum includes both in one formula.
- Insane Labz Pedigree: Built by a brand known for no-compromise, hard-hitting sports nutrition formulas.
- Full Ingredient Transparency: Beta-alanine, taurine, agmatine sulfate, and B vitamins — a complete advanced stack.
- Experienced-User Grade: Designed for athletes who have outgrown underdosed pre-workouts and need real intensity.

What Our Customers Are Saying
Redrum is the real deal. The energy hits fast and the pumps are insane. I've tried a lot of pre-workouts and this one actually delivers on every claim.
Verified Buyer
I was skeptical about the apple flavor but it actually tastes good. More importantly, the focus and energy carried me through a brutal leg day without fading.
Verified Buyer
The pump support in this formula is what sets it apart. Most high-stim pre-workouts skip that. Redrum gives you both and it shows in the mirror after training.
Verified Buyer
25 servings of pure intensity. I take it 20 minutes before training and by the time I hit the floor I'm completely locked in. Best pre-workout I've used this year.
Verified Buyer

Every serving is built to bring maximum intensity to your training. If your workout demands more, Redrum is made to answer.
