The Pump
Stimulant-loaded pre-workouts often constrict blood flow and diminish the muscle pump. PreHD Black addresses this with synergistic vasodilators that support nitric oxide production, enhance plasma expansion, and promote better muscle hydration.
GlycerSize™ (3,000 mg per 2 scoops)
This high-yield glycerol powder promotes muscle cell hydration and volumization by pulling water into muscle tissue. The result is increased fullness, endurance, and performance — plus lasting pumps.
Arginine Nitrate (NO3-T®) (2,000 mg per 2 scoops)
A patented nitrate-bound form of arginine known to boost nitric oxide levels more effectively than standard arginine. Helps improve blood flow, vascularity, and oxygen delivery to working muscles.
The Mindset
PreHD Black is built for lifters who need to lock in. Whether you're pushing through early mornings, tough sessions, or high-volume training blocks, this formula delivers the cognitive edge and drive to dominate every set.
L-Tyrosine (2,000 mg per 2 scoops)
A precursor to dopamine and norepinephrine, tyrosine helps improve mental focus, mood, and alertness — especially under stress or fatigue.
Caffeine Anhydrous + zumXR® (250 mg + 85 mg per 2 scoops)
Dual-release caffeine sources deliver an immediate surge of energy followed by a smooth, extended-release wave that minimizes crash while maximizing output and endurance.
DMAE (500 mg per 2 scoops)
A nootropic that enhances acetylcholine levels, supporting improved memory, focus, and neuromuscular control. Contributes to heightened mental clarity and task-oriented drive.
Huperzine A (10 mg per 2 scoops)
A potent inhibitor of acetylcholine breakdown. Helps prolong cognitive enhancement effects, sharpening focus and mind-muscle connection throughout your workout.
enXtra™ (600 mg per 2 scoops)
Derived from Alpinia galanga root, enXtra™ enhances alertness and attention, making it a valuable natural alternative or complement to caffeine for increased mental energy.
Synephrine HCL (24.6 mg per 2 scoops)
Supports energy and thermogenesis without increasing blood pressure. Helps activate beta-adrenergic receptors to enhance metabolic rate and workout intensity.
Absorption and Support
AstraGin® (50 mg per 2 scoops)
Enhances absorption and bioavailability of key nutrients. Ensures your body takes in the full benefit of each active ingredient for maximum effectiveness.
Directions for Use
Mix 1 scoop with 8–10 oz of cold water 20–30 minutes before training. To assess tolerance, begin with 1 scoop. Do not exceed 2 scoops per day.
Warning: PreHD Black is a high-stim product intended for advanced users. Due to its unique combination of potent stimulants and cognitive enhancers, start with 1 scoop to assess individual tolerance. Do not combine with other stimulant-based products.
PreHD Black delivers the energy, focus, pump, and drive needed to conquer every workout without compromise. This is not your average pre-workout — this is PreHD Black.
