Artvigil 150 lasts 10–12 hours after consumption. The drug boosts alertness and cognition without the peaks and crashes of caffeine. Artvigil takes 1–2 hours to work, peaking at 2 hours. After peaking, most users experience a steady fall in alertness and vigor. Its extended half-life (15 hours) prevents a quick comedown and maintains awake throughout the day. https://www.smartfinil.net/product/artvigil-150/
