excessive fatigue. The chemical formula for Adrafinil is C15H15NO3S. Adrafinil has an average mass of

and ChemAxon. Properties that were predicted by ACD/Labs showed 4 #H bond acceptors, 6 #Freely

rotating bonds, index of refraction at 1.653 with a surface tension of 67.3±3.0 dyne/cm. No information

Adrafinil (Olmifon) is a wakefulness-promoting agent (or eugeroic) used to relieve excessive sleepiness and inattention. It is also used off-label by individuals wishing to avoid fatigue,

such as night workersor others who need to stay awake and alert for long periods of time.

Adrafinil is the key to expanding your mental capabilities and maintaining your optimum level of

mental performance. Many vitamins, herbs, and drugs that can work wonders for the human mind

are fast becoming the source of intellectual dominance. From antioxidants like Vitamin C and

selenium that counteract the damaging effects of “free radicals,” to powerful nootropics such as

Adrafinil and Modafinil, each supplement is able to provide a unique mental advantage.


Dose: 600 to 1200mg daily. However, I have to point out that Olmifon was prescribed to the elderly

to combat excessive tiredness and narcolepsy, so this recommended dosage is intended as a guide

for those symptoms.
