400mg caffeine with creatine, AgmaMAX®, and fully disclosed dosing.
Core Nutritionals Fury is a straight-up, high-energy pre-workout with everything listed out clear. It pairs quick brain buzz with real gym support. Lots of high-stim pre-workouts just blast you with caffeine and weird stims for a fast start, then leave you hanging. Fury does it smarter. You get a strong hit from 400mg caffeine anhydrous and a mix of phenethylamines for that kick, but it also packs solid doses of creatine monohydrate, betaine anhydrous, agmatine sulfate, and citrulline to actually help your training.
The core is 5,000mg creatine monohydrate, the most researched boost in sports nutrition. At 5g, it's the standard daily amount to fill up your muscle's energy stores, helping recharge ATP during tough sets. In the gym, this means better explosiveness on repeats, holding onto strength across sets, and steady gains over time with regular use.
Fury throws in 2,000mg trimethylglycine as betaine anhydrous. Betaine acts like a cell hydrator, supporting power and output—studies often use around 2.5g. At 2g, it's a good dose here, teaming up with creatine to boost force and workout volume.
For pumps and flow, it's 3,000mg L-citrulline plus 1,500mg AgmaMAX® agmatine sulfate. L-citrulline boosts nitric oxide by raising arginine levels better than arginine does, skipping gut breakdown and working through the kidneys. Top studies use 6-8g, so 3g isn't the full solo dose. That said, Fury par
Core Fury Pre by Core Nutritionals contains 72mg Potassium, a effective dose for training performance and pump.
Key Highlights
- 5,000mg creatine monohydrate — a full daily dose of the best-researched gym booster. It helps refill quick energy in muscles for high-intensity sets, so you notice better strength holding up and real progress over time.
- 400mg caffeine anhydrous — this is real high-energy stuff, not some mild version. It fires up alertness, gets you in the zone fast, and keeps that drive going through tough workouts.
- 1,500mg AgmaMAX® agmatine sulfate — right at the high end of typical doses. Agmatine tweaks brain signals and supports nitric oxide, making pumps feel better and longer while working with citrulline.
- 3,000mg L-citrulline — not the top 6-8g dose on its own, but still solid for boosting arginine and nitric oxide. In Fury, it teams up with agmatine for better blood flow without trying to do it all alone.
- 2,000mg trimethylglycine as betaine anhydrous — a legit amount for a high-stim pre. Betaine hydrates cells and supports power, helping you push harder as tiredness builds.
- 1,000mg N-acetyl-tyrosine — this helps make stress-busting brain chemicals, turning the stim rush into focused drive instead of just wired jitters.
- 500mg choline bitartrate — boosts acetylcholine, which sharpens focus and muscle signals. You'll feel more connected and less scattered during hard sets.
- 400mg phenylethylamine HCl — adds a big mood lift and motivation kick. That's why Fury feels more pumped-up and fun than plain caffeine pre-workouts.

Who Is This For?
- Bodybuilders grinding hypertrophy who need more than caffeine. Fury delivers high-energy focus for volume, with 5g creatine, 2g betaine, 1.5g agmatine, and 3g citrulline boosting performance, hydration, and pumps in long sessions.
- Powerbuilders mixing heavies and volume. 400mg caffeine and phenethylamines amp intent for big sets, creatine handles energy repeats, betaine keeps power dense as you go.
- Seasoned pre users past basic 200mg stuff. If you know your limits and want harder drive without skimping on creatine and betaine, this fits.
- Early morning lifters needing quick motivation. Caffeine and phenethylamines switch you on fast, ergogenics prevent it from being a short buzz.
- Physique folks chasing mind-muscle feel. AgmaMAX® and citrulline build pumps and flow, choline and N-acetyl-tyrosine direct focus to form over just hype.
- Athletes in build phases where session quality counts. Creatine and betaine back repeats, stims hold intensity when tired.
How to Use
Mix 2 scoops in 12-16 oz cold water, down it 20-30 minutes before lifting. That lines up the 400mg caffeine and phenethylamines with your warmup. First-timer? Half it to test—high stims like this can pack a punch beyond the caffeine alone. Use a shaker for even mix, since it's a hefty 23.2g serve. Hits best empty stomach, but if stims bug your gut, pair with light food for slower build. No doubling up on other caffeine unless planned. Skip extra creatine—it's already 5g here—but electrolytes or carbs work for long hauls. Tolerance can creep, so save for tough days or switch up. Store sealed, cool, dry to keep it scoopable.
What to Expect
0-10 minutes: Starts with a smooth alertness lift from caffeine, hits quicker on empty stomach. 10-20 minutes: Energy ramps, phenethylamines boost mood and urge, focus sharpens with tyrosine and choline. 20-40 minutes: Peak time—max drive, aggression, and early pumps once moving. 40-90 minutes: Stays solid, caffeine holds energy while creatine, betaine, and pumps keep things productive without crashing. Days 1-7: Stim and focus hit hard first, creatine building. Weeks 2-4: Creatine stores up, betaine shines more in output and session feel.

Frequently Asked Questions
How much caffeine is in Core Nutritionals Fury?
At the full 2-scoop serving, Fury provides 400mg caffeine anhydrous. That places it firmly in high-stim territory, and the experience is intensified further by the phenethylamine complex, so it feels more aggressive than a plain 400mg caffeine formula.
Is Fury more of a stimulant pre-workout or a performance pre-workout?
Fury is primarily a high-stim pre-workout, but it is not just a stimulant bomb. It includes 5g creatine monohydrate, 2g betaine anhydrous, 1.5g AgmaMAX® agmatine sulfate, and 3g L-citrulline, giving it real performance and pump support alongside the energy complex.
Should I start with 1 scoop or 2 scoops?
If you have not used Fury before, start with 1 scoop to assess tolerance. The full 2-scoop serving delivers 400mg caffeine plus phenylethylamine derivatives, which can be too intense for users without established high-stim experience.
Does Fury contain a full creatine dose?
Yes. Fury provides 5,000mg creatine monohydrate per full serving, which is the standard clinical daily dose used to support phosphocreatine saturation, ATP regeneration, and long-term high-intensity performance.
Is the citrulline dose in Fury clinically dosed?
Fury contains 3,000mg L-citrulline, which is meaningful but below the most consistently studied standalone clinical range of 6-8g. The formula partially compensates by pairing it with 1,500mg AgmaMAX® agmatine sulfate to strengthen the overall pump and blood-flow experience.
What does AgmaMAX® do in this formula?
AgmaMAX® is a branded agmatine sulfate used here at 1,500mg, the top end of the common 500-1,500mg range. Agmatine acts as a neuromodulator and nitric oxide-support ingredient, helping enhance pumps, nutrient delivery, and the overall training feel when paired with citrulline.
Can I stack Fury with another creatine product?
You can, but most people do not need to because Fury already includes the full 5g creatine monohydrate daily target. A better stack would usually be something stim-free such as electrolytes, intra-workout carbohydrates, or a non-stim pump formula if you want to extend the blood-flow side.
Will Fury make me feel jittery?
It can if you are stimulant-sensitive. The combination of 400mg caffeine with PEA, beta-methylphenylethylamine, and N,N-dimethyl-beta-phenylethylamine is intentionally aggressive, so users prone to anxiety, rapid heartbeat, or overstimulation should choose a lower-stim option.
Can I use Fury every day?
You can use it on training days, and the creatine component actually benefits from consistent intake. The main consideration is stimulant tolerance: frequent high-caffeine use can blunt the subjective effect over time, so many experienced users reserve Fury for harder sessions or periodically rotate lower-stim days.
Is Fury beginner-friendly?
No, not as a full-serving pre-workout. The stimulant load is too aggressive for most beginners, even though the formula quality itself is solid; new users should either start with 1 scoop or choose a lower-stim formula first.
