Summary
Dehydroxyfluorafinil (Modafiendz) circulated briefly in the mid-2010s as an unscheduled eugeroic. User reports describe a functional but jittery alertness that feels harsher and more stimulant-like than armodafinil or modafinil. Doses above 100 mg are poorly characterized. User reports highlight inconsistent potency, occasional tachycardia, and vasoconstriction. Formal toxicology and human pharmacokinetic studies are absent.
