Zombie Labs King of Pumpz Non-Stim Pre-Workout – Big Pumps Without the Stimulants
Zombie Labs King of Pumpz non-stim pre-workout is built for lifters chasing massive muscle pumps without any stimulants. It loads up on pump-driving ingredients while still backing real performance — strength, volume and focus when you're deep in a set.
Key Benefits
- Serious muscle pumps — 10g of citrulline per serve drives blood flow into working muscle for that full, tight feeling.
- Pumps that last — Agmatine, pine bark and pump-sustaining compounds help keep the pump going long after your last set.
- Strength and volume support — A full creatine complex and beta alanine back your output when fatigue sets in.
- Focus under fatigue — A nootropic blend supports mental drive and aggression in the gym.
- No stimulants — Train hard without caffeine, so it won't keep you up if you lift late.
How It Supports Your Training
This isn't an entry-level pump product. King of Pumpz pushes blood into the muscle and holds it there, while creatine and beta alanine support the work itself. That means bigger pumps, more reps under load, and the kind of intensity advanced lifters are after. Because it's stim-free, you can stack it with a stim pre-workout or use it on its own for late sessions.
Suitable For
Experienced lifters who want extreme muscle fullness and pump without stimulants. Per the brand, stacking with End of Dayz is only suggested for advanced lifters who understand the combination.
FAQs
Will this keep me awake if I train at night?
No. King of Pumpz is a non-stim pre-workout, so there's no caffeine or other stimulants to interfere with sleep. It's a solid option for late-night sessions.
Can I stack this with a stim pre-workout?
Yes. Because it's stim-free, it pairs with a separate stimulant pre-workout. Zombie Labs notes the End of Dayz stack is only for advanced lifters who know what that combination does.
