How it works
Increases wakefulness by converting into modafinil, supporting prolonged focus and reduced fatigue.
Overview
Adrafinil acts as a prodrug to modafinil, meaning it is metabolised in the liver into its active form. This results in a slower onset compared to modafinil but can still provide sustained cognitive stimulation. It is typically used for acute performance demands rather than daily use. Due to its metabolism pathway, frequent use may place strain on the liver, so it is generally recommended for occasional use.
