What you will notice

Days 1 to 7: sharper attention and quicker recall within half an hour of each dose, lasting most of the day. Weeks 2 to 4: steadier energy for mental work, better mood under pressure and less afternoon fog. Weeks 4 to 6: the gains hold between doses as BDNF-driven wiring builds. Longer: people cycle it, 4 to 6 weeks on and 2 to 4 off, and keep the baseline higher each round.
