🛡️ Zero-Headache Withdrawal Protocol

  • ✓Drink 500ml of cold water with a pinch of Celtic or Pink Himalayan salt immediately upon waking to prevent blood pressure drop headaches.
  • ✓Take 1,000mg–1,500mg L-Tyrosine 30 minutes before your workout during Days 5–12 to maintain dopamine synthesis without central nervous system burnout.
  • ✓Maintain training volume: Do not skip workouts during the washout. Rely on vasodilators (6g–8g L-Citrulline) for nitric oxide pump without adrenal stimulation.
  • ✓Take 300mg Magnesium Glycinate 45 minutes before sleep to facilitate restorative delta-wave sleep and accelerated neuro-receptor repair.

⚡ Stim-Free Performance Swap

Washout Approved

Do not train flat during Days 9–12. Replace stimulants with full clinical dosages of pure vasodilators and cell volumizers.
