Take your training to the absolute limit with Pre JYM by JYM Supplement Science, the high-performance pre-workout that completely redefined the supplement industry. Formulated by world-renowned sports scientist Dr. Jim Stoppani, Pre JYM bypasses cheap marketing gimmicks and "proprietary blends" to deliver 14 scientifically validated ingredients at full clinical doses. Designed for dedicated athletes, powerlifters, and fitness enthusiasts, this premium formula supports clean energy, explosive physical power, rapid recovery, and massive muscle pumps without the dreaded post-workout crash.
Pre JYM boasts a fully transparent label featuring 14 active, research-backed ingredients. Each serving provides 6g Citrulline Malate to support robust blood flow and vascularity, alongside 6g BCAAs (in a 2:1:1 ratio) to fuel working muscles and fight intra-workout fatigue. To maximize power, you get 2g Con-Cret® Patented Creatine HCl and 1.5g Betaine, paired with 2g Beta-Alanine to help buffer lactic acid accumulation. Energy and focus are driven by a clean 300mg Caffeine Anhydrous, 1.5g L-Tyrosine, 150mg Alpha-GPC, and 50mcg Huperzine A, while 5mg BioPerine® supports maximum nutrient absorption.
Pre JYM represents the pinnacle of sports nutrition honesty. Unlike competitor formulas that hide cheap ingredients under proprietary blends, Jim Stoppani's formula is fully disclosed so you know exactly what is entering your body. Manufactured in a GMP-compliant facility in the USA, it combines premium quality, refreshing flavors, and verified purity. When you scoop Pre JYM, you are choosing real science for real results.
💡 Pro Tip
Mix 1 scoop of Pre JYM in 16 to 24 ounces of cold water and consume it 30 to 45 minutes before training. If you are sensitive to caffeine, start with 1/2 scoop or less to assess your tolerance, and avoid taking within 6 hours of bedtime to ensure a good night's rest.
