Darkside® Onslaught™ | Advanced High-Intensity Stim Pre-Workout

Darkside® Onslaught™ is a premium, high-intensity training catalyst designed to support consistent athletic output and mental focus. Formulated with a fully transparent ingredient matrix, this pre-workout provides clear dosing of proven ergogenic aids to optimize strength, endurance, and target muscle volume.

 

FORMULA HIGHLIGHTS

  • Vasodilatory Pump Engine: Includes 3500mg L-Citrulline to naturally stimulate nitric oxide production and skeletal muscle vascularity.
  • Muscular Stamina Support: Includes 2000mg Beta-Alanine to buffer lactic acid accumulation and delay training fatigue.
  • Precision Cognitive Matrix: Includes 500mg CDP-Choline to support acetylcholine neurotransmission and maintain training intent.
  • Sustained Energy Curve: Features 150mg Caffeine Anhydrous to increase physical alertness without triggering systemic spikes or crashes.

 

HOW IT WORKS

Darkside® Onslaught™ delivers a controlled stimulant and pump experience by coordinating muscle vascularization with neurological support. Nitric oxide synthesis is enhanced to relax blood vessel walls, increasing localized oxygen and substrate delivery to working limbs during demanding lifts.

Intracellular carnosine levels are replenished to manage internal cellular pH balance during intense sets, while focused neurotransmitter precursors support neurotransmitter pathways to prevent mental fatigue under stress.

 

SUGGESTED USE

Mix 1 scoop with 250-350 ml of cold water and consume 20-30 minutes before training. Start with 1/2 scoop to assess tolerance. Do not exceed the recommended daily intake. Do not combine with other stimulants.
