USP Labs Jack3d Pre Workout - 45 Servings

When a pre workout carries a reputation like Jack3d, athletes take notice. USPLabs’ Jack3d (sometimes stylised Jack3d™) burst onto the supplement scene over a decade ago, and its cult status endures because it delivers intense energy, tunnel vision focus and vascular pumps without filling your shaker with unnecessary sugars or fillers. As your trusted reseller, Nutritional Supplement Shop is proud to offer the latest Jack3d formula to our customers across the United States. This article explains what makes Jack3d so potent, how to use it safely, and why buying from Nutritional Supplement Shop gives you peace of mind.

What Is Jack3d?

Jack3d is a concentrated pre workout powder designed for serious lifters and high intensity athletes. The current formula is a high stim pre workout that combines caffeine, geranium extract, β alanine, creatine monohydrate and other performance boosting compounds. USPLabs describes Jack3d as an “intense powder pre workout … enhanced with Geranium extract”. The product is known for delivering crazy energy, tunnel focus and bursting pumps. Unlike many competitors, Jack3d does not rely on bulky fillers; the tiny container holds concentrated active ingredients such as arginine alpha ketoglutarate, creatine monohydrate, β alanine, caffeine, geranium extract, 2 aminoisopheptane (DMHA), yohimbe extract and schizandrol A, giving you more impact per scoop.

Proprietary Blend and Active Ingredients

According to supplement facts from a US retailer, each scoop (5.5 g) provides a proprietary blend of 4,145 mg including arginine alpha ketoglutarate, creatine monohydrate, β alanine, caffeine, DMHA (2 aminoisopheptane HCl), geranium extract, yohimbe extract and Schisandra chinensis extract. A full 3 scoop serving (16.65 g) contains 12,435 mg of the same blend. Each scoop delivers about 135 mg of caffeine, and the maximum 3 scoop serving provides 405 mg. The formula also uses flavouring agents and sweeteners such as citric acid, natural and artificial flavours, acesulfame K and sucralose.

Why Athletes Love Jack3d?

• Intense Energy & Focus: Customers report that a single 4.15 g scoop is enough to produce powerful energy and focus. The blend of caffeine, DMHA and geranium extract acts as a central nervous system (CNS) stimulant, giving you a clean rush that powers you through leg day or HIIT sessions.
  
• Research Backed Ingredients: USPLabs emphasises that Jack3d includes only proven ingredients and omits fillers, so you’re paying for performance rather than hype.
  
• Vascular Pumps: The combination of arginine alpha ketoglutarate and β alanine supports nitric oxide production and buffering of muscle acidity, producing the “bursting pumps” that bodybuilders crave.
  
• Compact Container: Because Jack3d avoids fillers, the container is small and easy to take to the gym.
  

Suggested Use & Dosage Guidelines

Jack3d is a powerful stimulant; correct dosing is crucial for safety. According to NutriCartel’s suggested use guidelines, mix 1–3 scoops with 6–12 oz (180–360 ml) of cold water and consume one serving per day. On workout days, take your serving 30–60 minutes before resistance training or cardio. Shake the container before each use because contents may settle and do not exceed 3 scoops per day.

Dosage Recommendations

• New Users: Start with ½-1 scoop to assess tolerance. Jack3d’s high caffeine and DMHA content means that even one scoop can feel potent. Some athletes report needing only one scoop for an entire workout.
  
• Experienced Users: If you have used high stim pre workouts before and tolerate stimulants well, you may gradually increase to 2 scoops. Only the most tolerant users should attempt 3 scoops (which yields ~405 mg caffeine), and it should never be used more than once daily or for longer than 8 weeks.
  
• Cycle Length: Do not use Jack3d continuously; follow an on/off cycle (e.g., 8 weeks on, several weeks off) to prevent tolerance and reduce stress on your body.
  

How to Take Jack3d?

• Hydration: Drink plenty of water throughout your workout. Stimulants and β alanine can increase body temperature and may dehydrate you.
  
• Pre Exercise Nutrition: To minimise stomach discomfort, consume a light meal 60-90 minutes before taking Jack3d.
  
• Avoid Other Stimulants: Jack3d already contains a high stimulant load. Do not combine it with other sources of caffeine or synephrine (coffee, energy drinks, fat burners, etc.).
  

Who Should Use Jack3d?

Jack3d is designed for healthy adult athletes (18 years or older) who require intense focus and energy for high intensity workouts. Bodybuilders, powerlifters, athletes preparing for a competition or anyone doing demanding training sessions may find Jack3d beneficial. Its concentrated formula makes it a favourite for those seeking maximum stimulus in minimal volume.

Who should avoid it?

• Under 18, Pregnant or Nursing: The product explicitly states it is not for individuals under 18 or for pregnant/nursing women.
  
• People Sensitive to Stimulants: Those who are sensitive to caffeine or DMHA should consult a healthcare professional before using Jack3d.
  
• Individuals with Medical Conditions or on Medications: If you have heart, liver, kidney or thyroid disease, psychiatric disorders, high blood pressure, cardiac arrhythmia, enlarged prostate, glaucoma or other serious health conditions, speak with your doctor before using Jack3d. The supplement may also interact with medications such as MAO inhibitors, NSAIDs or antidepressants.
  
• Women of Childbearing Age: Even if you are not pregnant, consider alternatives if you plan to conceive because stimulants can influence hormonal balance.
  

Safety Warnings

Jack3d is potent, and safety is paramount. The manufacturer and retailers include extensive warnings:

• Limit use to 8 weeks and take breaks to prevent adverse effects.
  
• Avoid alcohol while taking this product, and discontinue use two weeks before surgery.
  
• Side effect awareness: If you experience rapid heartbeat, dizziness, severe headache or shortness of breath, discontinue use immediately and seek medical advice.
