Who Is This For?

God of Fire is built for lifters who:

  • Are on a weight loss journey but want to sustain performance—not just one or the other
  • Train during cutting phases and need sustained energy
  • Are tired of stimulants that spike and crash without results
  • Understand that real fat loss comes from discipline and training right
  • Demand full-dose ingredients with zero proprietary blends

If you're new to thermogenic pre-workouts or sensitive to stimulants, start with ½ scoop or try God of Fire first.

What You'll Feel
  • Heat: Thermogenic activation you can feel—increased body temperature and sweat production
  • Energy: Clean, sustained drive from 350mg caffeine without jitters or anxiety
  • Pump: Serious vasodilation and blood flow from 4g L-Citrulline and 1g L-Arginine
  • Focus: Locked-in mental clarity powered by CitraFuze™ and nootropics
  • Endurance: Extended work capacity from beta-alanine buffering fatigue
  • After: Hours of sustained energy with minimal crash when properly refueled
How It Works

Most thermogenic products overpromise and under-deliver, relying on caffeine alone or hiding weak doses in proprietary blends.

God of Fire is engineered for real metabolic activation:
The Thermogenic Engine:

  • GBB (50mg) converts to L-Carnitine, forcing your body to burn stored fat for energy
  • Yohimbine HCl (3mg) targets stubborn fat by blocking alpha-2 receptors
  • Theobromine (100mg) extends thermogenesis and enhances mood without overstimulation

The Energy System:

  • Caffeine Anhydrous (350mg) delivers immediate, powerful CNS activation
  • Mucuna Pruriens (50mg) supports dopamine production for sustained motivation
  • CitraFuze™ (100mg) provides natural alkaloids for cognitive support

The Performance Foundation:

  • L-Citrulline Malate (4g) drives nitric oxide production for maximum blood flow
  • Beta-Alanine (4g) buffers lactic acid to delay muscle fatigue
  • L-Arginine (1g) supports the nitric oxide pathway for enhanced pump
  • D-Aspartic Acid (500mg) supports natural hormone production and recovery

The Focus Lock:

  • Huperzine-A (200mcg) protects acetylcholine for extended mental clarity

How to Use
  • New to thermogenics: 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 thermogenic formula. Expect increased body heat and sweat production—this means it's working. Stay well-hydrated throughout your workout and after.

Plan to train for at least an hour when taking God of Fire, as the thermogenic effect continues beyond your session. Refuel with a post-workout meal to prevent lethargy and support recovery.

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.

God of Fire is built differently. GBB (Gamma Butyrobetaine) forces your body to produce L-Carnitine, which shuttles stored fat into cells to be burned as energy. Yohimbine targets stubborn fat areas by blocking alpha-2 receptors. This isn't just caffeine making you feel warm—it's thermogenesis at work. Combine it with training and proper nutrition, and you'll see the difference.

You'll feel heat — that's thermogenesis working. But jitters are unlikely. God of Fire uses 350mg caffeine (moderate for a stim pre) with Theobromine to smooth the energy curve. That said, if you're new to thermogenic formulas, start with half a scoop. Expect to sweat more than usual—that's the point. Stay hydrated and plan to train for at least an hour.

Yes. Every lot of God of Fire 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.

Absolutely. God of Fire works for anyone who wants energy, pumps, and performance. The thermogenic effect is a bonus—it won't interfere with muscle building or strength training. If you're in a surplus and just want a great workout, God of Fire delivers. The fat-burning benefits are there if you need them, but they won't hurt your gains if you don't.

If you are a healthy adult, yes! Start with ½ scoop and see how you feel. You can always try a full scoop later. Remember not to use more than 1 scoop a day.

We ship orders as soon as possible. Weekdays, orders that come in before 4-5pm EST typically ship the same day. We ship on Saturdays too, although our carrier pickup times vary. But we can assure Friday evening orders ship. Federal Holidays and USPS errors and delays are out of our control, but we do our best to help ensure every supplement gets to you safely and securely.

If you see some sort of issue in transit, please reach out to us kindly to make us aware. We will stay proactive in the process until you receive your order. Call or text us at (717) 884-4254 if you need us!

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.®
