Who Is This For?

Blood Rush is built for lifters who:

  • Want maximum pumps without stimulants, jitters, or crashes
  • Train late or stack with their own stimulant pre-workout
  • Are sensitive to caffeine but still demand serious vascularity
  • Understand that real pumps come from blood flow, not tingles
  • Want full transparency with zero proprietary blends

Perfect on its own for stimulant-free sessions or stacked with God of War, God of Rage, God of Fire, or God of Thunder for ultimate results.

What You'll Feel
  • Pump: Skin-splitting muscle fullness and extreme vascularity
  • Blood Flow: Maximum nitric oxide production and nutrient delivery
  • Endurance: Extended work capacity from enhanced oxygen transport
  • Hydration: Deep intracellular water retention for 3D muscle fullness
  • Focus: Clear mind-muscle connection from L-Tyrosine and blood flow agents
  • After: No crash, no jitters—just sustained performance and recovery

Zero beta-alanine tingles. Zero caffeine anxiety. Just pure pump.

How It Works

Blood Rush is engineered for one thing: maximum vasodilation. Every ingredient works synergistically to flood working muscles with blood, oxygen, and nutrients.

The Nitric Oxide Engine:

  • L-Citrulline Malate (4,000mg) drives NO production for peak blood flow
  • L-Arginine AKG (3,000mg) directly supports the nitric oxide pathway
  • Agmatine Sulfate (1,500mg) enhances pump and nutrient delivery
  • NitroRocket® (500mg) arugula extract amplifies NO for extended vasodilation

The Hydration & Fullness Matrix:

  • Glycerol Monostearate (3,000mg) pulls water into muscle cells for extreme fullness
  • Vitamin C (500mg) supports endothelial function and blood vessel health

The Mind-Muscle Connection:

  • L-Tyrosine (1,000mg) enhances focus and mental clarity under stress
  • L-Norvaline (300mg) inhibits arginase to prolong NO production
  • Huperzine A (100mcg) protects acetylcholine for sustained concentration

Pure pump. Zero stimulants. Maximum blood flow.

How to Use
  • Beginners: ½ scoop in 6–12 oz water, 30 min before training
  • Experienced: 1 full scoop in 10–12 oz water, 30 min before training
  • Maximum: Never exceed 1 scoop in 24 hours

This is a dense pump formula. Mix with at least 10–12 oz of water for optimal consistency. Small white particles that don't fully dissolve are normal—they're part of the powerful pump matrix inside.

Stacking: Can be combined with any stimulant pre-workout for maximum results. Do not exceed 1 serving of any stimulant product in 24 hours.

Product Care Warning

Do not leave your pre-workout in a hot or cold car. Extreme temperatures can:

  • Cause clumping or hardening of the powder
  • Break down active ingredients, reducing effectiveness
  • Alter flavor and overall product quality


For best results:

  • Store in a cool, dry place with the lid tightly closed
  • Use within 90 days of opening for maximum freshness and potency

God of rage + Blood Rush

This stack is phenomenal for my workouts on heavy lift days. The sustainability and fact there is zero crash from the pre ensure I have a great pump every time. As someone who has a long workout routine I love the longevity without having to add additional caffeine while in the middle of my session.

Stellar products

I’ve tried all 3 hi stim pre’s and blood rush. They all deliver exactly as promised! Very high quality and a great workout partner. Only issue I had was I couldn’t stop sweating with God of fire for a few hours after my workout. So no good for days that I go to work after the gym, lol. But I enjoyed that one too, nonetheless.

One if the best high stim pres available

All the high stims offer to be THE preworkout and this one delivers. I have not trued GOd Of Fire yet and it's probably next on my list but this one I feel was the best of all I've tried in the stim category yet and I've trued alot of high stim preworkouts over the years. The peach mango is a good flavor but their grape is the best in taste in my opinion. Nice energy delivery with a minimum amount of tingles but enough to notice. I'd definitely recommend it if your tolerance is high. If it isn't try a half scoop. Good stuff guys.

Frequently Asked Questions

No matter what your question is about our products, the team at Centurion Labz is always on hand to provide prompt and accurate answers.

Yes—but it works differently. Blood Rush doesn't give you energy or euphoria. It gives you pumps. Real, skin-splitting vasodilation from 4g L-Citrulline, 3g Glycerol, and 3g L-Arginine. If you've been chasing pumps with stim pre-workouts and never getting them, it's because stimulants constrict blood vessels. Blood Rush solves that. Stack it with your stim pre, or take it solo. Either way, you'll finally see what a real pump feels like.

Absolutely. Blood Rush is 100% stimulant-free. Zero caffeine. Zero beta-alanine tingles. Just pure vasodilation and focus from L-Tyrosine and Huperzine-A. It's built for late-night training sessions when you need performance but can't afford to be wired for hours afterward. Train at 9 PM, sleep by midnight.

Yes. Every lot of Blood Rush is 3rd party lab tested before it ships. We use zero proprietary blends—every ingredient and exact dose is printed on the label. No hiding. No guessing. This isn't marketing. It's the Centurion standard: if it's on the label, it's in the tub—verified.

That's the pump matrix. Blood Rush is a dense, large-scoop formula packed with active pump ingredients. Specifically, the stearic acid component of the Glycerol Monostearate doesn't fully dissolve in water, which is why you may see small white particles even after mixing. This is normal and proves that the ingredient on the label is in the product. Mix with at least 10-12 oz of water for best consistency, and shake or stir well before drinking.

Yes, that's one of the main use cases. Blood Rush is designed to stack with any stimulant pre-workout—God of War, God of Rage, God of Fire, God of Thunder, or even your own choice. Just don't exceed 1 serving of any stimulant product in 24 hours. Blood Rush adds the pump your stim pre is missing. Together, they deliver the complete package: energy, focus, and vascularity.

Centurion Labz was started by 2 Doctors in Langhorne, PA in 2014 inside a local gym. It rapidly grew to other gyms, then mom and pop retail stores, and then international distributors.

Trevor Nolan Bower first discovered Centurion Labz at the Arnold Sports Festival in 2016, and he recognized something rare – a brand that delivered real value without relying on hype.

He brought Centurion Labz into his retail store, where it quickly became the standout brand. Trevor, who witnessed the dark sides of the supplements industry both as a consumer and as a retail store owner, made a commitment to help others reach their fitness goals with the right information, community, and supplements.

In 2020, he acquired the company with one mission: take what already worked – and make it better without compromising what made it special. 

Today, Centurion Labz maintains full label transparency, third-party tests every batch, and operates with the same hands-on approach that built its reputation. Every product was created from our own personal experiences and the voices of our customers through face-to-face conversations.

Centurion Labz has sold over 1 million tubs of pre-workout to more than 100,000 lifters and the owner still personally answers customer calls - in addition to designing product labels, working with manufacturers, hands on marketing, and maintaining the standards of the brand across all operational aspects.

He ensures that the right expectations are being set for our community; not overhyped and unrealistic expectations. The goal is always to explain what our products do, how to best use them, and what we recommend to do alongside the products to get the best results. We stand firm against the typical marketing tactics that the industry uses to push quick sales. We care most about making a difference in the lives of others. We wouldn't be in this business if we weren't accomplishing that everyday through our efforts. Competing in such a big industry as a small brand in the current economy is a challenging task, but we're pushing through with our passions at the forefront of everything we do.

We didn’t grow through marketing. We grew by staying accountable to the people we serve. Please, anytime you have any questions, call or text us ahead of placing your order. We want you to have the support to make the best decisions possible!

We represent the legendary Centurion warriors - the Roman officers that led 100 Roman troops. These warriors were defined by discipline, preparation, and unity.

The Centurions understood that preparation determines outcome – that the battle is often decided before it begins. From that principle comes our core belief: Preparation Is the First Act of Victory.

We carry that same principle into training. That’s why we specialize in pre-workout. We believe preparation determines performance.

Pre-workout isn’t hype. It’s a decision — one that sets the foundation for everything that follows.

The workout is won before the first rep.®
