Jack3d Pre-Workout by USP Labs: The Ultimate Pre-Workout Matrix

Jack3d by USP Labs is a legendary name in the supplement world, and it's back with a revamped and more potent formula that’s turning heads in the fitness industry. Known as one of the most iconic pre-workouts ever made, Jack3d originally set the standard for energy and performance supplements before it was temporarily pulled from shelves. Now, USP Labs has reintroduced this powerhouse with a modern twist, featuring the cutting-edge stimulant DMHA (2-Aminoisoheptane), combined with caffeine and other intense energy-boosting ingredients.

This ultra-concentrated pre-workout delivers unparalleled energy, razor-sharp focus, and incredible muscle pumps, making it a favorite for experienced gym-goers and "stim junkies" alike. Whether you're tackling a grueling weightlifting session or an intense cardio workout, Jack3d is designed to help you crush your fitness goals.

What Makes the New Jack3d Formula So Powerful?

The revamped 2019 formula of Jack3d features DMHA, an advanced stimulant designed to deliver explosive energy and mental clarity. Combined with geranium extract, caffeine, and other proprietary blend components, this formula offers a high-intensity experience that sets it apart from the competition. DMHA provides similar effects to the original DMAA formula, offering a clean energy boost, improved focus, and a stronger mind-muscle connection—all without the controversial ingredient DMAA.
