Description
Centurion Labz God of War
450mg of caffeine per serving. That is tied for the strongest pre-workout on our shelf, and it is the most stimulant-heavy product Centurion Labz make.
⚠ Start at half a scoop. Whatever your tolerance, whatever you currently take. Half a scoop of this is stronger than a full scoop of most pre-workouts.
Founded in Langhorne, Pennsylvania — the same town, the same year
Centurion Labz was started by two doctors in Langhorne, PA in 2014 — inside a local gym. Coalition Nutrition opened in Langhorne in 2014 too.
Same town, same year. This brand grew out of the same few square miles we did, spreading from that one gym to other gyms, then to independent shops, and eventually to international distribution. It was acquired in 2020 by Trevor Bower, who found it at the Arnold Sports Festival in 2016.
Centurion Labz maintains full label transparency and third-party tests every batch — which matters enormously on a product this strong.
⚠ 450mg in context
Worth sitting with these numbers before you buy.
| This product | 450mg per serving |
| FDA daily figure for healthy adults | 400mg, including everything else you drink |
| A large coffee | Roughly 200mg |
| A typical energy drink | 150 to 200mg |
One serving exceeds the entire daily figure on its own. That is not a reason nobody should take it — plenty of experienced lifters use products in this range — but it is a reason to take it deliberately rather than habitually.
- Half a scoop in 8 to 12oz of water, 20 to 30 minutes before training
- Never more than one serving in 24 hours
- Nothing else with caffeine that day. No coffee, no energy drink, no fat burner
- Not within six hours of bed. Caffeine has a long half life and sleep matters more than the session
Where it actually sits in the Centurion range
| Blood Rush | 0mg | Stim-free pump. Stacks with anything |
| Nemesis | 0mg | Stim-free pump |
| God of Fire | 350mg | The lowest of the three stimulant options |
| God of Rage UNCHAINED | 425mg | Multi-stimulant blend |
| God of War | 450mg | The strongest they make |
If you are new to Centurion, God of Fire is the sensible entry point — and if you are new to pre-workout entirely, start at 200mg and work up over months.
⚠ The tolerance trap, and why this should not be your daily driver
This is the most useful thing we can tell anyone buying at this level, and it will save you money.
Caffeine tolerance builds with regular exposure. Take 450mg every session and within a few months you will need more than 450mg to feel the same thing.
There is almost nothing above this. A handful of products reach 460 to 500mg and that is the ceiling of what is sensible. You end up spending more, feeling less, with nowhere left to go.
The way to keep this working is to not use it often. Run something moderate for your ordinary sessions and save God of War for the ones that genuinely warrant it. You will spend less and get more from both.
And if you have already hit the ceiling, the answer is a two week break from stimulants rather than a stronger tub. Tolerance resets faster than people expect.
⚠ Stimulants partly work against your pump
Caffeine is a vasoconstrictor. Citrulline and glycerol are vasodilators. They oppose each other to a degree, which is why the strongest product on a shelf does not reliably give the best pump.
If pumps are your priority, this is not the product for that. A moderate-stimulant pre-workout plus Blood Rush will usually produce a better pump than God of War alone — which is exactly why Centurion make both.
How to read the rest of the label
Centurion disclose every dose rather than using a proprietary blend, which means you can actually run these checks:
- Citrulline: pure or malate? Malate is roughly a third malic acid, so 8g of malate delivers about 5.3g of actual citrulline. The researched range is 6 to 8g of actual — see our L-Citrulline page
- Beta-alanine should be 3.2g. The tingle is paraesthesia, it fades with regular use, and it tells you nothing about whether the product works
- Betaine should be 2.5g if present
Full disclosure matters most on a product this potent, because it lets you see exactly what you are taking rather than trusting a blend total.

Who this is for
- Experienced pre-workout users with a well established stimulant tolerance
- Anyone whose current product has genuinely stopped doing anything
- People training heavy in the morning or early afternoon
- Anyone who wants a fully disclosed label on a high-stimulant product
- Customers who like buying from a brand that started in Langhorne
Who this is not for
Beginners. Genuinely. Start at 200mg and climb slowly over months.
Anyone with anxiety. High-stimulant products are among the most likely things on our shelves to trigger it.
Anyone with high blood pressure or a heart condition, without speaking to a doctor first.
Anyone training in the evening. Use Blood Rush instead.
Anyone who drinks coffee through the day. One serving already exceeds the FDA daily figure on its own.
Anyone wanting a daily driver. Tolerance will take this from you within months.
Anyone on mood or blood pressure medication, without medical advice. Tested athletes should check the full panel against their federation's list.
Not for anyone under 18, pregnant or nursing.
Stack it with: Blood Rush for the pump the stimulants work against, and creatine daily.
Frequently asked questions
How much caffeine is in God of War?
450mg per serving. That is tied for the strongest pre-workout we stock, and it exceeds the FDA's 400mg daily figure for healthy adults on its own.
How much should I take?
Half a scoop to start, whatever your tolerance. Never more than one serving in 24 hours.
Is it stronger than God of Rage?
Yes. God of War is 450mg and God of Rage UNCHAINED is 425mg. God of Fire is 350mg and is the lowest of the three.
Can I have coffee as well?
No. One serving already exceeds the daily figure, so nothing else with caffeine that day.
Can I take it every session?
You can, but tolerance builds quickly at this level and there is almost nothing stronger available. Save it for the sessions that warrant it.
What if nothing works any more?
A two week break from stimulants rather than a stronger product. Tolerance resets faster than people expect.
Will it give me a good pump?
Caffeine is a vasoconstrictor and citrulline a vasodilator, so they oppose each other. If pumps are the priority, pair a moderate pre-workout with a stim-free pump product instead.
Why does it make me tingle?
Beta-alanine. Harmless paraesthesia that fades with regular use, and not a sign the product is working.
