Stim-Free Pre-Workout Supplements

All Power. No Stimulants.

Looking for high-performance training support without caffeine or stimulants? Our Stim-Free Pre-Workout collection brings you the best in non-stim formulas to power your workouts, without the crash.

At MJ Fitness, we’ve curated a premium range of stim-free pre-workout supplements that deliver serious results: increased blood flow, muscle pump, endurance, and focus with zero caffeine or nervous system stimulation.

These formulas are perfect for:

• Late night sessions

• Caffeine sensitive individuals

• Stacking with other products

• Or anyone wanting to cycle off stims without losing performance

Expect ingredients like L-Citrulline, Beta-Alanine, Nitrosigine, GlycerPump®, and nootropics all clinically dosed to support intense training, improve nutrient delivery, and maximise your pump.

Unlike standard pre-workouts, stim-free options rely on enhanced circulation, cellular hydration, and mental clarity to give you that locked-in feel, minus the jitters or post-session fatigue.

Whether you're chasing insane pumps, enhanced performance, or a clean formula that fits your lifestyle, MJ Fitness has you covered with trusted brands that deliver results.

Level up your workout on your terms.

No stims. No compromise. Just pure performance.
