Core Nutritionals | Fury Pre | 20 Servings

Core Nutritionals Fury is a fully disclosed, high-stimulant pre-workout built around a simple but effective formulation philosophy: pair immediate neural drive with legitimate gym-floor performance support. A lot of high-stim pre-workouts rely almost entirely on caffeine and exotic stimulants to create a strong first 20 minutes, then leave the rest of the workout to momentum. Fury takes a smarter route. It still delivers a hard-hitting stimulant experience with 400mg caffeine anhydrous and a layered phenethylamine complex, but it also includes meaningful doses of creatine monohydrate, betaine anhydrous, agmatine sulfate, and citrulline so the formula has real training utility beyond just feeling wired.

The backbone starts with 5,000mg creatine monohydrate, the most studied ergogenic ingredient in sports nutrition. At 5g, this is the classic evidence-based daily dose used to saturate muscle phosphocreatine stores, supporting ATP regeneration during repeated high-intensity efforts. In practical terms, this is the ingredient in Fury most associated with better repeated explosiveness, strength retention across working sets, and long-term performance progression when used consistently.

Fury also provides 2,000mg trimethylglycine as betaine anhydrous. Betaine functions as an osmolyte, helping support cellular hydration and power output, and research often centers around the 2.5g range. At 2g, Fury is still meaningfully dosed and clearly positioned to complement creatine by supporting force production and training volume rather than replacing it.

For pumps and blood flow, the formula uses 3,000mg L-citrulline plus 1,500mg AgmaMAX® agmatine sulfate. L-citrulline is a strong nitric oxide ingredient because it raises arginine more effectively than arginine itself by bypassing first-pass metabolism and converting in the kidneys. The strongest sports nutrition data generally sits around 6-8g, so 3g is below the most consistently clinical standalone range. That said, Fury partially offsets that with a full 1.5g of AgmaMAX®, which sits at the top of the commonly used 500-1,500mg range. Agmatine is a neuromodulator with emerging performance data and a strong reputation in pre-workouts for enhancing pumps, nutrient delivery, and training feel, especially when paired with citrulline. The result is not a maxed-out pump formula, but a notable, performance-relevant blood-flow component inside a stim-first product.

The focus and drive complex is where Fury becomes distinctly aggressive. Choline bitartrate at 500mg supports acetylcholine production for neuromuscular signaling and concentration, while 1,000mg N-acetyl-tyrosine is included to support catecholamine synthesis under stress. Then the phenethylamine stack—400mg phenylethylamine HCl, 250mg beta-methylphenylethylamine HCl, and 50mg N,N-dimethyl-beta-phenylethylamine HCl—pushes mood, urgency, and the euphoric, locked-in feel many experienced high-stim users actively seek. Combined with 400mg caffeine anhydrous, this creates a fast, assertive onset and a very noticeable central nervous system effect.

Synergistically, Fury makes sense. Caffeine amplifies alertness and output, tyrosine and choline help keep that stimulation task-oriented, phenethylamines intensify drive and workout engagement, while creatine and betaine support the actual muscular work once the set starts. Citrulline and agmatine improve the delivery side of the equation through blood flow and pump dynamics. Importantly, the label is fully transparent with no proprietary blend, which matters in a category where many high-stim pre-workouts hide stimulant amounts or underdose their performance ingredients.

What to expect: on day one, Fury is primarily an energy, mood, and focus experience with a noticeable pump support layer. Over 2-4 weeks of regular use, the creatine becomes more meaningful as muscle stores saturate, and the betaine support becomes more relevant to work capacity and output. The stimulation hits now; the performance support earns its value over time.
