Evidence-graded stacking partners for Amphetamine (Adderall). Synergistic and neutral combinations are listed alongside pairings to avoid. Use this to design a deliberate stack rather than experimenting blind.
Combine with caution (1)
- ModafinilEVIDENCEA
A eugeroic — a wakefulness-promoting compound — originally developed for narcolepsy. The most-studied prescription cognitive enhancer outside of ADHD treatment. Produces 12–15 hour windows of sustained alertness without the euphoria, abuse potential, or cardiovascular load of amphetamines. Prescription-only in nearly every jurisdiction.
Both elevate DA. Manageable under MD; cardiovascular monitoring advised.
Avoid stacking (1)
- MethylphenidateEVIDENCEA
Prescription stimulant for ADHD (Ritalin, Concerta). Increases dopamine and norepinephrine.
Duplicate prescription stimulants — switch, don't stack.
