Analysis

Pre JYM High-Performance Pre-Workout stands out due to its fully disclosed ingredient label, which is a significant advantage in a market often plagued by proprietary blends. It provides a robust combination of performance enhancers like Citrulline Malate (6g), Creatine HCl (2g), Beta-Alanine (2g), and BCAAs (6g at 2:1:1 ratio), alongside a potent energy and focus blend including 300mg Caffeine, 1.5g L-Tyrosine, 150mg Alpha-GPC, and 50mcg Huperzine A. This comprehensive profile is designed to support multiple workout goals, from strength and endurance to mental acuity. While the Beta-Alanine dose is slightly below the commonly studied clinical range for full benefits (typically 3.2g+), and Alpha-GPC is a bit lower than some optimal nootropic doses, the overall synergy of ingredients is impressive. Reviews generally praise its effectiveness in delivering sustained energy, noticeable pumps, and sharp focus without a harsh crash. The price per serving is on the higher side, but it reflects the quality and quantity of active ingredients per dose.

Pros
  • Comprehensive formula with transparent ingredient dosages, avoiding proprietary blends.
  • Contains clinically studied ingredients for performance (Citrulline, Creatine, Beta-Alanine, BCAAs) and cognitive benefits (Caffeine, Tyrosine, Alpha-GPC, Huperzine A).
  • High caffeine content (300mg) provides a strong and reliable energy boost.
  • Includes BCAAs in a good ratio for muscle support and recovery during workouts.
  • Supports enhanced blood flow and muscle pumps with Citrulline Malate and Beet Root Extract.
Cons
  • High price per serving ($1.79) compared to many other pre-workout supplements on the market.
  • The Beta-Alanine dose (2g) is slightly below the most commonly studied clinical range (3.2-6.4g daily) for maximizing endurance benefits and paresthesia reduction.
  • Alpha-GPC dose (150mg) is on the lower side for maximum cognitive enhancement, with many studies using 300-600mg.
  • Very low potassium (77mg) and sodium (10mg) content, which are insufficient for significant electrolyte replenishment during intense physical activity.
Warnings
  • High caffeine content (300mg) may cause jitters, anxiety, increased heart rate, or difficulty sleeping for individuals sensitive to stimulants.
  • Not suitable for individuals with pre-existing cardiovascular conditions or those advised to limit caffeine intake.
  • Contains Beta-Alanine which can cause a harmless tingling sensation (paresthesia), although at 2g it might be less pronounced than higher doses.
