Product Detail

High-impact pre-workout support designed to elevate energy, focus and training intensity.
This advanced pre-workout formula is scientifically developed to help maximise every training session by supporting explosive energy output, enhanced focus and sustained performance. Carefully selected performance ingredients work together to help you train harder, push further and stay locked in from the first set to the last.

Combining powerful pump agents, endurance-supporting amino acids and natural caffeine, this formula is built for athletes who demand more from their workouts. Added nootropic and adaptogenic extracts support mental clarity and stress resilience, helping you stay sharp and driven even during high-intensity training.

  • Supports explosive energy and training intensity
  • High-dose citrulline malate to promote blood flow and muscle pump
  • Beta-alanine to support endurance and reduce fatigue
  • Natural caffeine for clean energy and focus
  • Nootropic and adaptogenic extracts to support mental performance

SUGGESTED USE
Mix 2 scoops (15g) with 300ml of water and consume approximately 30 minutes before training. Advanced users may take up to 4 scoops (30g) mixed with 500–600ml of water as two servings once tolerance has been assessed. Do not exceed the maximum recommended daily intake.
