Centurion Labz God of Fire — Thermogenic Pre-Workout, 350mg Caffeine

Centurion Labz God of Fire A thermogenic pre-workout — built for training in a deficit, fasted cardio and cutting phases. 350mg of caffeine alongside a stimulant and thermogenic matrix, 25 servings, fully disclosed. ⚠ Start at half a scoop, and never exceed one scoop in 24 hours. Centurion are direct about this and so are we. ⚠ Why the caffeine number understates this product This is the most important thing on the page, and it corrects an easy mistake. God of Fire carries 350mg of caffeine, which is lower than God of War at 450mg. It does not follow that it is a gentler product. Caffeine is simply the ingredient that is easiest to measure and compare. Perceived intensity comes from the whole stimulant matrix, and God of Fire carries several ingredients that hit hard at small doses: Isopropylnorsynephrine — a synephrine derivative sometimes described as a modern alternative to DMHA. Strong energy and mood effects, with genuine thermogenic activity Yohimbine HCl, and related alkaloids such as quebrachine — alpha-2 antagonists, potent in milligrams rather than hundreds of milligrams Theobromine — caffeine's longer-acting relative from cocoa, which smooths and extends the curve Huperzine A — inhibits acetylcholinesterase, contributing to the focus rather than the stimulation Judge a pre-workout by its whole label, not by the caffeine figure alone. A product at 350mg with four additional stimulants can feel considerably stronger than one at 450mg with none. What "thermogenic" actually means here God of Fire is a different tool from the rest of the Centurion range rather than a weaker version of it. The thermogenic side is genuinely present, and one ingredient explains the effect people notice most: GBB (gamma-butyrobetaine) is a precursor your body converts into carnitine. It is also the reason for the single most commonly reported experience with this product — sweating heavily, sometimes for hours after the session has finished. That is expected rather than alarming. If you have read a review describing someone still sweating after showering, GBB is why. Some people find it satisfying and some find it genuinely unpleasant, which is worth knowing before you buy a tub rather than after. Vitamin B3 (niacin) can add a flushing sensation on top of that — warmth and skin reddening. Also harmless, also worth expecting. ⚠ Take it fasted, and understand why Alpha-2 antagonists such as yohimbine work best on an empty stomach. Alpha-2 receptors act as a brake on fat release, and stubborn areas carry more of them. Yohimbine blocks that brake — but insulin blunts the effect substantially, so food undermines the mechanism you are paying for. That is why this pairs naturally with fasted morning cardio, and why it suits a cutting phase more than a bulk. ⚠ And yohimbine is the ingredient most likely to cause problems. Anxiety, racing heart, elevated blood pressure and nausea are all commonly reported, particularly in anyone already stimulant-sensitive. If you have anxiety, avoid this product. Yohimbine has been used in research specifically to provoke anxiety responses. The Centurion range — three different jobs Blood Rush0mg caffeineStim-free pump.

Centurion Labz God of Fire

A thermogenic pre-workout — built for training in a deficit, fasted cardio and cutting phases. 350mg of caffeine alongside a stimulant and thermogenic matrix, 25 servings, fully disclosed.

⚠ Start at half a scoop, and never exceed one scoop in 24 hours. Centurion are direct about this and so are we.

⚠ Why the caffeine number understates this product

This is the most important thing on the page, and it corrects an easy mistake.

God of Fire carries 350mg of caffeine, which is lower than God of War at 450mg. It does not follow that it is a gentler product.

Caffeine is simply the ingredient that is easiest to measure and compare. Perceived intensity comes from the whole stimulant matrix, and God of Fire carries several ingredients that hit hard at small doses:

Isopropylnorsynephrine — a synephrine derivative sometimes described as a modern alternative to DMHA. Strong energy and mood effects, with genuine thermogenic activity
Yohimbine HCl, and related alkaloids such as quebrachine — alpha-2 antagonists, potent in milligrams rather than hundreds of milligrams
Theobromine — caffeine's longer-acting relative from cocoa, which smooths and extends the curve
Huperzine A — inhibits acetylcholinesterase, contributing to the focus rather than the stimulation

Judge a pre-workout by its whole label, not by the caffeine figure alone. A product at 350mg with four additional stimulants can feel considerably stronger than one at 450mg with none.

What "thermogenic" actually means here

God of Fire is a different tool from the rest of the Centurion range rather than a weaker version of it.

The thermogenic side is genuinely present, and one ingredient explains the effect people notice most:

GBB (gamma-butyrobetaine) is a precursor your body converts into carnitine. It is also the reason for the single most commonly reported experience with this product — sweating heavily, sometimes for hours after the session has finished.

That is expected rather than alarming. If you have read a review describing someone still sweating after showering, GBB is why. Some people find it satisfying and some find it genuinely unpleasant, which is worth knowing before you buy a tub rather than after.

Vitamin B3 (niacin) can add a flushing sensation on top of that — warmth and skin reddening. Also harmless, also worth expecting.

⚠ Take it fasted, and understand why

Alpha-2 antagonists such as yohimbine work best on an empty stomach. Alpha-2 receptors act as a brake on fat release, and stubborn areas carry more of them. Yohimbine blocks that brake — but insulin blunts the effect substantially, so food undermines the mechanism you are paying for.

That is why this pairs naturally with fasted morning cardio, and why it suits a cutting phase more than a bulk.

⚠ And yohimbine is the ingredient most likely to cause problems. Anxiety, racing heart, elevated blood pressure and nausea are all commonly reported, particularly in anyone already stimulant-sensitive. If you have anxiety, avoid this product. Yohimbine has been used in research specifically to provoke anxiety responses.

The Centurion range — three different jobs

Frequently asked questions

Is God of Fire weaker than God of War?
It has less caffeine, at 350mg against 450mg, but it is not a gentler product. Perceived intensity comes from the whole stimulant matrix, and God of Fire carries isopropylnorsynephrine, yohimbine, theobromine and huperzine A alongside the caffeine.

Why does it make me sweat so much?
GBB. It is a carnitine precursor and heavy sweating is its most commonly reported effect, sometimes continuing for hours after training. Expected rather than alarming, though some people find it genuinely unpleasant.

Should I take it fasted?
Yes, if fat loss is why you bought it. Insulin blunts the alpha-2 mechanism that yohimbine works through, so food substantially reduces the effect.

Why do I feel flushed?
The niacin. Warmth and skin reddening are harmless and pass.

How much should I take?
Half a scoop to start, one full scoop once you know how you respond, and never more than one scoop in 24 hours.

Can I take it with a fat burner?
No. Most fat burners contain yohimbine or rauwolscine, and doubling the same mechanism is where anxiety and racing heart come from.

Which Centurion pre-workout should I buy?
God of Fire if you are cutting or doing fasted cardio. God of War or God of Rage if you are not — they are built for output rather than fat loss.

Can tested athletes use it?
No. Yohimbine and synephrine derivatives appear on prohibited lists.
