Samurai Science - Samurai X - Pre Workout

Samurai Science – Samurai X Pre Workout is a full-spectrum, high-stimulant pre-workout designed to cover the three levers that matter most in training: pump/blood flow, performance output, and locked-in focus/drive.

On the pump and performance side, a full serving (2 scoops) delivers 9,000 mg L-Citrulline plus a dense supporting stack—3,200 mg Beta-Alanine, 5,000 mg Betaine Anhydrous, 1,000 mg Agmatine Sulfate, and a standout dose of VasoDrive-AP® (508 mg)—aimed at stronger pumps, better training density, and higher-quality working sets.

For energy and intensity, Samurai X combines multiple stimulant and drive inputs, including Theobromine (600 mg) and Caffeine Anhydrous (200 mg), plus Caffeine Citrate (100 mg) which the label notes yields ~50 mg caffeine per full serving—making this a stimulant-forward formula best suited for experienced users.

Finally, the “Mushin • Fudoshin™ Matrix” targets mental output and coordination with L-Tyrosine (2,000 mg), Alpha GPC (50%) (600 mg), Lion’s Mane (500 mg), and Huperzine A (20 mcg)—a nootropic-style blend intended to support focus, drive, and training intent when fatigue and distractions creep in.

Benefits

• Supports strong pumps and blood flow for higher-quality sessions

• Helps drive work capacity and high-intensity endurance (notably via beta-alanine)

• Promotes power, output, and training volume support (betaine + performance stack)

• Delivers high-stimulant energy and “drive” support for demanding training days

• Supports focus, alertness, and mind-muscle connection via nootropic-style ingredients

• Includes electrolyte support (sodium) to complement hard training and sweating

• Includes absorption support (Bioperine) to round out the formula

Ingredient Breakdown

Pump, Blood Flow, and Training “Fullness”

• L-Citrulline (9000 mg): A nitric-oxide-supporting amino acid precursor (via conversion to arginine). Commonly used to support vasodilation, pumps, and blood flow during training.

• VasoDrive-AP® (508 mg): A branded ingredient associated with supporting healthy blood flow and circulation pathways. Often included in pump-focused formulas to complement nitric-oxide strategies.

• Agmatine Sulfate (1000 mg): A compound related to arginine metabolism that is commonly used in pre-workouts for “pump” support and training intensity feel.

• Black Ginger Extract (100 mg): Botanical extract frequently used in performance formulas; typically positioned for circulation and physical performance support.

Performance Output and Work Capacity

• Beta-Alanine (3200 mg): Supports muscle carnosine levels, helping buffer training-induced acidity—often felt as improved high-intensity endurance and better ability to sustain hard sets. May cause harmless tingling in some users.

• Betaine Anhydrous (5000 mg): An osmolyte and methyl donor commonly used to support power output, muscular endurance, and training volume.

• Sodium (250 mg): Key electrolyte that supports hydration status and neuromuscular function—useful when training hard and sweating.

Stimulant Energy and Drive

• Caffeine Anhydrous (200 mg): Classic stimulant that supports alertness and perceived energy through adenosine receptor antagonism.

• Caffeine Citrate (100 mg; yields ~50 mg caffeine): A caffeine source where the label specifies approximate caffeine yield. Often used to complement other caffeine inputs and shape onset/feel.

• Paraxanthine (100 mg): A primary metabolite of caffeine commonly positioned for energy and focus support with a “cleaner” profile in some users.

• Theobromine (600 mg): A methylxanthine (commonly associated with cacao) often described as a smoother stimulant adjunct, frequently used to complement caffeine-based energy.

• Eria Jarensis Extract (350 mg): Botanical extract commonly included in “drive” blends for stimulant-like intensity and mood/drive support.

• Catuaba Bark (350 mg): Traditional botanical used in “mood/drive” positioning in performance supplements.

• English Ivy Extract (300 mg): Botanical ingredient often associated with respiratory and breathing support positioning; included in some performance formulas to complement training feel.

• Halostachine HCl (50 mg): Stimulant-leaning compound sometimes used in high-energy pre-workouts for drive and intensity support.

• Pregnenolone (5 mg): A steroid-hormone precursor used in some formulations for mood/cognitive positioning. Because hormone-related pathways can be individualized, this is an ingredient many users prefer to discuss with a qualified clinician prior to use.

Focus and Cognitive Output

• L-Tyrosine (2000 mg): Amino acid precursor to catecholamine neurotransmitters (dopamine/norepinephrine), commonly used to support focus under stress and fatigue.

• Alpha GPC (50%) (600 mg): Concentrated choline source used to support acetylcholine-mediated focus and mind-muscle connection.

• Lion’s Mane (500 mg): Mushroom ingredient widely used for cognitive support positioning.

• Huperzine A (20 mcg): Often used to support acetylcholine signaling by slowing breakdown (acetylcholinesterase inhibition). Because it can be potent even in microgram amounts, many users choose to cycle it or avoid stacking with other strong cholinergics.

Absorption Support

• Bioperine (10 mg): Black pepper extract (piperine) used to support nutrient bioavailability. Note: piperine can affect absorption of certain medications for some individuals.

How to Use

• Assess tolerance first: If you’re sensitive to stimulants, consider starting with ½ serving to evaluate response.

• Full serving: Mix 2 scoops with water and take 20–30 minutes before training.

• Avoid late dosing: Do not take close to bedtime due to stimulant content.

• Do not combine irresponsibly: Avoid stacking with other high-stimulant products or heavy caffeine intake.

• Hydrate: Pumps and performance ingredients work best when hydration is supported.

Who Is It For

• Experienced pre-workout users who want a pump + performance + high-stim drive profile

• Lifters training for hypertrophy, strength, bodybuilding-style volume, or high-output sessions

• Individuals who value focus and intensity as much as physical energy

• Not ideal for: stimulant-sensitive users, those avoiding strong “drive” blends, or anyone who prefers low-stim formulas

FAQ

How much caffeine is in a full serving?
The label lists Caffeine Anhydrous (200 mg) plus Caffeine Citrate (100 mg) yielding ~50 mg caffeine per full serving—so total caffeine is approximately ~250 mg from these sources, based on the label’s yield note.

Will I feel tingles?
Possibly. Beta-Alanine (3200 mg) can cause a harmless tingling sensation in some users (paresthesia), especially when taken on an empty stomach.

Is this a beginner-friendly pre-workout?
This is a high-stimulant formula. Beginners typically do better starting with a lower-stim product or using a reduced amount to assess tolerance.

Can I stack this with a pump product?
Yes—many users stack with a stim-free pump formula. Monitor total intake to avoid excessive gastrointestinal load and avoid adding additional stimulants.

Can I take this every day?
Many users reserve high-stim pre-workouts for harder training days to help manage tolerance. If using frequently, consider cycling stimulant exposure.

Does it use artificial sweeteners?
Yes. The label lists Sucralose and Acesulfame Potassium.

I’m drug-tested for sport—any concerns?
If you compete in tested federations or are subject to drug screening, it’s prudent to verify ingredients with your governing body and request documentation from the manufacturer when available.
