Aug 12, 2025 MuscleTech Stacked Pre: Workout Energy, Focus, & Power with New HydroNOx L-Citrulline HCl!
MuscleTech Stacked Pre delivers 300mg caffeine, HydroNOx citrulline, and yohimbe extract for maximum energy and pumps. High-intensity pre-workout supplement.
DOMINATE EVERY REP
Forget outdated mega-dosing. Stacked Pre is powered by HydroNOx Citrulline HCl, a next-gen breakthrough that delivers 2.9x the results with just 2 g—outperforming the typical 6 g doses of standard L-citrulline.¹
To enhance this pre-workout stack, we’ve added patented NO3-T, plus performance-calibrated energy and endurance matrices featuring VitaShure, GeniusPure and Senactiv—delivering a powerhouse sensory experience along with sustained energy, razor-sharp focus, and peak stamina. This isn’t just a pre-workout. This is the next evolution.
MASSIVE PUMPS
Supercharges blood flow for unmatched vascularity and pumps.¹
EXPLOSIVE ENERGY
Delivers sustained power to tackle the toughest challenges—without crashes.²
FASTER ABSORPTION
43% faster than L citrulline for superior nitric oxide production.¹
BETA-LEVEL PRECISION
Unrivaled ingredient stack for purity and potency in every dose.
¹In a clinical study, test subjects who consumed 2 g of HydroNOx experienced a 43% quicker conversion into arginine in the blood (60 min vs 105 min) and 1.6x peak arginine in the blood compared to 6 g of regular L-citrulline over a 3-hour measurement period (18.5 µM/g vs 11.5 µM/g). In the same study, test subjects experienced 2.9x the conversion rate of L-citrulline to arginine when ingesting 2 g of HydroNOx compared to 6 g of L-citrulline (0.67 vs 0.23). ▲
²The energy and sensory matrix, powered by caffeine, delivers extreme focus.▲
