The Jacked Factory NitroSurge Pre-Workout, regardless of flavor, features an identical and transparent ingredient profile aimed at providing energy, mental focus, and mood support. The caffeine content at 180mg is a standard and effective dose for pre-workout energy without being overly stimulating for most users. The inclusion of 90mg of L-Theanine is crucial, as it synergizes with caffeine to provide a smoother energy curve, reducing jitters and enhancing focus. Theobromine (50mg) adds a milder, longer-lasting stimulant effect, contributing to a sustained sense of well-being. From a performance perspective, L-Citrulline is dosed at 3000mg, which is at the lower end for significant pump effects (typically 6-8g is recommended for optimal vasodilation). Beta-Alanine (1600mg) and Betaine Anhydrous (1250mg) are both significantly underdosed compared to their clinically effective amounts (3.2g+ for Beta-Alanine, 2.5g for Betaine), meaning users may not experience their full benefits for endurance and power output. AstraGin (50mg) is a valuable addition for enhancing nutrient absorption. Online reviews generally highlight good energy and focus without a crash, aligning with the stimulant and nootropic profile. However, some users might find the performance aspects lacking due to the suboptimal dosages of certain ergogenic aids.
