There is no established or legitimate human dose. Fladrafinil is an essentially UNSTUDIED grey-market 'research chemical' analogue of modafinil and a prodrug of flmodafinil, with no human clinical trials, no approval, and no pharmacovigilance — this library does NOT provide a dosing protocol. Vendors and forums quote figures in the tens-to-low-hundreds of milligrams orally, extrapolated from modafinil/adrafinil, but these are unverified for a product of unknown purity and identity, taken without medical supervision or monitoring. The only human datapoint is a 2026 doping-control study in which six volunteers ingested 20 mg of fladrafinil (or flmodafinil) to map metabolism, prodrug conversion and detection — a detection study, NOT a dosing or efficacy recommendation.

Morning

No human form is endorsed — fladrafinil is an unstudied 'research chemical' analogue/prodrug of modafinil with no approved or supplement form

• Any human use — fladrafinil is an essentially UNSTUDIED grey-market 'research chemical' and a prodrug of flmodafinil, with no human trials, no approval, and product of unverified identity, purity and dose; it is NOT a dietary supplement and NOT an approved medicine
• Anyone seeking it for focus, wakefulness or 'nootropic' enhancement — there is no human evidence of benefit for fladrafinil and an extrapolated modafinil-like harm profile
• Anyone with cardiovascular disease, arrhythmia, uncontrolled hypertension, or left-ventricular hypertrophy — modafinil-class agents raise blood pressure and heart rate

• Hormonal contraceptives
• Other stimulants / caffeine / sympathomimetics
• CYP3A4 / CYP2C19 substrates (e.g. some statins, benzodiazepines, certain antidepressants, warfarin)
