What to expect

Early

Days 1–7

30 to 60 minutes: the hallmark calm-focus effect is acute and felt the same dose, especially noticeable stacked with caffeine.

Mid

Weeks 2–4

Weeks 1-4: with regular use, day-to-day stress reactivity and sleep onset may improve.

Later

Weeks 4–12

Ongoing: a stable, non-escalating benefit that works well as an as-needed or daily tool.
