Key Benefits
Modafinil
01 Sustained wakefulness and alertness for 10-15 hours without the jitteriness of traditional stimulants
02 Enhanced executive function, working memory, and decision-making under fatigue
03 Improved focus and concentration during prolonged cognitive tasks
04 Reduced impulsivity and improved task completion in sleep-deprived individuals
05 Low abuse potential relative to amphetamine-class stimulants (Schedule IV)
06 Minimal impact on normal sleep architecture when taken in the morning
NA Semax Amidate
01 Direct brain access via olfactory nerves
02 Rapid onset (15-30 minutes)
03 Proven cognitive efficacy
04 Extended half-life vs standard Semax
05 Enhanced BDNF upregulation
Dosing Protocols
Modafinil
100-200 mg/day / Once daily (morning)
NA Semax Amidate
600-1200mcg per administration / 1-2x daily for 10-30 days
