JACK3D Pre-Workout | Unleash the Original Extreme Energy & Focus
For a generation of athletes, the name wasn’t just a supplement; it was an experience. It was a promise scribbled on tubs in gym bags worldwide. It was the definitive edge. That name is JACK3D, and its legacy is now engineered for the modern warrior. Crafted by USPLabs, JACK3D returns—not as a relic, but as a redefined apex predator in the pre-workout arena. This is not merely a pump product. This is a comprehensive neurological and physiological ignition system designed to shatter plateaus, vaporize mental fog, and propel you into a state of hyper-concentrated, relentless performance.
If your training has felt routine, if the weights haven’t felt lighter, if you’ve been searching for that seismic shift in workout quality—your search ends here. JACK3D is the catalyst.
Ordinary pre-workouts offer a simple stimulant lift. JACK3D orchestrates a symphony of performance. We target the foundational pillars of legendary training sessions: extreme mental drive, explosive physical energy, unparalleled muscular endurance, and powerful vasodilation. The result is a state of mind and body known as "The Tunnel"—a laser-focused, adrenaline-charged zone where distractions cease, pain thresholds elevate, and every rep, sprint, or leap is executed with ruthless intent.
JACK3D is engineered for the individual who views the gym as a proving ground. It is for strength athletes chasing new PRs, for bodybuilders sculpting under extreme volume, for CrossFit® athletes navigating brutal metcons, and for any athlete who demands that their supplement match their ambition.
Every serving of JACK3D is a precision-dosed matrix of clinically researched ingredients, each selected for a definitive role in the performance cascade.
1. The Neurological Launchpad: Extreme Energy & Focus
Infiniti-Focus™ (150mg Caffeine Anhydrous): The cornerstone. This is not a slow-release blend; it’s a high-purity, rapid-absorption energy surge. It aggressively binds to adenosine receptors in the brain, delaying the perception of fatigue and exhaustion. The mental alertness is sharp and immediate, transforming "I have to workout" into "I get to destroy this workout."
NeuroFactor™ (100mg Coffee Arabica Fruit Extract): This innovative co-factor works synergistically with caffeine. Derived from the whole coffee fruit, it is clinically shown to increase levels of Brain-Derived Neurotrophic Factor (BDNF)—a key protein for cognitive function, focus, and learning. This isn't just about feeling alert; it's about being acutely connected to your mind-muscle link.
N-Acetyl L-Tyrosine (300mg): A potent form of the amino acid Tyrosine, a precursor to crucial neurotransmitters like dopamine, norepinephrine, and epinephrine (adrenaline). Under the physical and mental stress of intense training, Tyrosine levels deplete. Supplementation helps maintain cognitive function, drive, and stress resilience, keeping your motivation locked in from the first warm-up set to the final, grinding rep.
2. The Physical Performance Engine: Power, Output & Endurance
BetaPower™ Pure Betaine (1.5g): A game-changer for strength and power output. Betaine (trimethylglycine) works as an osmolyte, protecting cells from stress, and more critically, it significantly increases the body's production of creatine phosphate—the primary fuel for short, explosive efforts. Peer-reviewed studies consistently show Betaine's ability to increase muscle force, power output, and training volume, meaning you lift heavier, longer.
Creatine Monohydrate (3g): The most researched, proven performance ingredient in sports nutrition history. JACK3D includes a substantial dose to rapidly saturate muscle phosphocreatine stores. This translates to faster ATP regeneration between reps and sets, drastically improving work capacity, reducing recovery time within your workout, and promoting lean mass gains over time.
L-Citrulline (3g): The optimal vasodilator. Unlike Citrulline Malate (which is part malic acid), our L-Citrulline is pure and highly dosed. Once converted to L-Arginine in the kidneys, it elevates plasma arginine levels, stimulating the production of Nitric Oxide (NO). This leads to dramatic vasodilation—the "pump." But beyond aesthetics, this enhances blood flow, delivering more oxygen and nutrients (like the creatine and betaine you just ingested) to working muscles while efficiently clearing metabolic waste like lactate and ammonia. The result? Muscles that feel fuller, work harder, and resist fatigue longer.
3. The Metabolic Ignition & Finish
Velox™ (Rauwolscine [Alpha-Yohimbine] 1.5mg): The final piece of the performance puzzle. This selective alpha-2 adrenergic receptor antagonist promotes a sharp, clean energy feel and supports fat mobilization during training. It helps counteract the vasoconstrictive effects of caffeine in certain fat tissues, promoting a lean, hard, and vascular physique appearance as you train.
The Legendary "Feel": There is a distinct, undeniable sensation that defines a true performance pre-workout. JACK3D delivers it—a clean, intense, and focused surge that aligns mind and body for the task ahead.
Transparent, Impactful Dosing: No proprietary blends that hide ingredient amounts. You see exactly what you're getting, and more importantly, you get doses that are backed by science to actually work.
No-Fluff Formula: JACK3D is stripped of unnecessary fillers. It’s a potent, concentrated formula where every component has a defined performance role.
Engineered for the Hardcore: From the stimulant profile to the endurance and power complexes, this formula was built for high-output, high-demand training styles.
Athletes experiencing performance plateaus.
Strength and power athletes seeking to increase 1RM and volume.
Bodybuilders and fitness enthusiasts chasing an unparalleled pump and mind-muscle connection.
Endurance athletes needing sustained power and fatigue resistance.
Any disciplined trainee with stimulant tolerance seeking a powerful, focused experience.
Mix one scoop (approximately 9.4g) with 6-8 oz of cold water 20-30 minutes before training. Due to its potent stimulant content, assess your tolerance. Do not exceed one scoop in a 24-hour period. For optimal results, cycle usage (e.g., 8-12 weeks on, 2-4 weeks off). Take on training days only. Do not consume if you are sensitive to stimulants, pregnant, nursing, or under medical supervision. Consult a physician before use.
Q: Is this the "original" JACK3D formula?
A: USPLabs has reformulated JACK3D to meet modern regulatory standards and leverage the latest in sports nutrition science. While the specific ingredient profile has evolved, the core mission—delivering extreme energy, focus, and performance—remains identical, and the "feel" is powerfully familiar.
Q: How does the focus compare to other pre-workouts?
A: The combination of high-dose caffeine, NeuroFactor™, and N-Acetyl L-Tyrosine creates a unique neuro-stimulant stack that promotes both acute alertness and sustained cognitive drive, setting it apart from caffeine-only products.
Q: Can I use this for cardio or just weights?
A: JACK3D is exceptionally versatile. The endurance components (Creatine, Betaine, Citrulline) and energy drivers make it equally effective for high-intensity interval training (HIIT), sprint sessions, sport-specific conditioning, and weight training.
Q: Will I experience a "crash"?
A: The formula is designed for a sharp onset and a gradual, controlled descent. Proper hydration and nutrition post-workout are key to mitigating any residual effects.
Taste the Legacy. Feel the Fury. Stop preparing for mediocre workouts. It’s time to prepare for domination. Add JACK3D to your cart now and experience the reawakening of performance. Your next personal record is waiting.
