In this video I will discuss Modafinil vs Adrafinil Modafinil and Adrafinil are currently the only two members of the Eugeroics class Eugeroics act as stimulants and promote wakefulness They were developed to replace amphetamine use Eugeroics are relatively non-addictive and non-dependence-forming Adrafinil is the earlier version of Modafinil Modafinil is the main metabolized element from Adrafinil and Both drugs have similar activity, but Adrafinil requires a larger dose for an equal effective strength Adrafinil targets the same brain receptors and makes them more responsive to norepinephrine, But it is not as specific or potent as Modafinil Users who have tried both have noted some differences Adrafinil has a motivational effect and users are keen to undertake intellectual work They will often stick with the task in hand for far longer than normal, This effect is less intense in Modafinil, but still present Adrafinil is reported to produce a form of 'inner tension' that Modafinil does not produce Adrafinil produces a more down and dirty sort of stimulation, Conversely Modafinil stimulation has been subjectively evaluated as 'finer' It is easier to fall asleep after Modafinil, then after Adrafinil Modafinil does not seem to produce any post dose exhaustion And works when taken consecutively for a number of days Average doses of Adrafinil are higher: 600-1200mg/day for Adrafinil versus 200-400mg/day for Modafinil
