- Chronic useBenefits, if any, accrue over weeks—this is not an acute stimulant.
Pairing with dual n-back

- Track stressNote perceived stress during sessions and sleep quality to see if recovery improves.
- Layer basicsSleep, training schedule, and nutrition still drive the main performance gains.
