Zombie Labs COMPOUND Z Ultimate High-Stim Pre-Workout

Zombie Labs Compound Z is the most stimulant-forward pre-workout the brand has ever built — a genuine high-stim pre-workout engineered for lifters who want everything dialled up at once. Packing 505 mg of caffeine, a full nootropic stack and a 12,200 mg pump matrix per full serve, it delivers extreme energy, skin-splitting pumps and laser focus in a single hit. This is not a beginner formula. It's built for experienced stim users chasing the hardest-hitting, most vascular session of their week. Why Choose Zombie Labs Compound Z 505 mg caffeine per full serve — the highest-stim pre-workout in the Zombie Labs range, for extreme, sustained energy. 3800 mg beta alanine — a genuine clinical dose to support muscular endurance (expect the signature tingle). 12,200 mg Explosive Pump Synthesis blend — 6000 mg citrulline, betaine nitrate and AgmaPure® agmatine work across a dual nitric oxide pathway for maximum blood flow and vascularity. 2661 mg Laser Focus Nootropic Catalyst — nine ingredients including L-tyrosine, alpha-GPC and huperzine A to drive focus and a sharp mind-muscle connection. 50 mg TeaCrine® (theacrine) — amplifies and extends the caffeine effect without adding to the caffeine total. AstraGin® plus added B-vitamins — supports absorption and helps convert food into usable energy. Four bold flavours — Wicked Watermelon, Passion Mango Mayhem, Savage Sour Straps and Raspberry Ripper. What Is a High-Stim Pre-Workout? A high-stim pre-workout is built around a large, fast-acting stimulant dose — typically high-dose caffeine paired with supporting compounds — to produce intense energy, alertness and drive going into a training session. Compound Z sits at the top of this category with 505 mg of caffeine per full serve, layered with theacrine to extend the effect and a nootropic complex to keep that energy sharp and focused rather than scattered. Because the stimulant load is significant, a high-stim formula like this is best suited to experienced users who already tolerate caffeine well, and is not intended for anyone sensitive to stimulants. How To Use New users, or anyone building tolerance, should start with the Half Bitten serve — 1 level scoop (10.8 g), providing 252 mg of caffeine — to assess tolerance. Experienced stim users can progress to the full Full Zombie serve — 2 level scoops (21.6 g), providing 505 mg of caffeine. Mix your chosen serve with 250–350 ml of cold water and consume 20–30 minutes before training. Do not exceed one full serve in any 24-hour period, and avoid use within 6 hours of bedtime due to the high caffeine content. Servings: 20 full serves (Full Zombie) or 40 half serves (Half Bitten) per tub. Always read the label and use only as directed. Contains caffeine (252 mg per 1 scoop) — not suitable for children, pregnant or breastfeeding women, or those sensitive to caffeine. Phenylketonurics: contains phenylalanine. May contain milk, soy, wheat, gluten, nuts, seeds, sulphites and fish. If symptoms persist, see your healthcare professional.
