High-Stim Pre-Workout Supplements

Not for the Faint-Hearted.

If you're chasing full throttle intensity, look no further than our High-Stim Pre-Workout collection. These formulas are engineered for seasoned lifters, serious athletes, and anyone who wants to go beyond the limits of ordinary pre-workouts.

At MJ Fitness, we stock Australia’s most powerful high-stim pre-workouts, loaded with hard hitting stimulants, nootropics, and performance enhancers to fuel maximum energy, focus, and drive.

Expect ingredients like:

• Caffeine anhydrous, Di-Caffeine Malate, English Walnut and other energy ingredients

• Alpha GPC, Huperzine A, and other mental sharpness agents

• Beta-alanine, L-citrulline, and other pump & endurance supports

These aren’t your average pre’s. They’re designed for those who train with intent, who want tunnel vision focus, next-level motivation, and the kind of energy that pushes through any plateau.

Perfect for early morning sessions, heavy lifting days, or when you need a serious kick to get moving, high-stim pre-workouts can help you:

• Smash PBs

• Power through fatigue

• Train with more aggression and intensity

But make no mistake, these are not beginner-friendly. Always start with a half serve if you’re new to high-stim formulas.

High energy. High impact. High performance. Only at MJ Fitness.
