Evidence-based Synthesis
Modafinil is a powerful eugeroic, but it does not operate in a vacuum. Its long 12-15 hour half-life means it will interact with almost any other compound you consume during the day.
This hub maps out exactly how Modafinil interacts with stimulants, neuroprotectants, and sleep aids.
The Modafinil Cluster
- Modafinil and ADHD: Managing executive dysfunction and off-label protocols.
- Modafinil and Caffeine: The synergistic half-life overlap and overstimulation risks.
- Modafinil and Elvanse (Vyvanse): Stacking eugeroics with amphetamine prodrugs safely.
- Modafinil and Methylphenidate: DRI synergy and the risk of extreme anxiety.
- Modafinil and Melatonin: Forcing sleep latency when the modafinil half-life drags.
- Modafinil and Magnesium: Clearing the excitotoxic calcium load from NMDA receptors.
- Modafinil and L-Tyrosine: Replenishing the dopamine synthesis bottleneck.
