Provigil has been added to the Prohibited List of the World anti-doping agency in 2004, as a stimulant.

It has received some negative publicity, after a few athletes were discovered using Provigil for enhancing the performance. It is still not know how widespread it is.

There has been no studies done to check what effect Provigil has on physical performance of a person, so due to similarity an action to amphetamine, it’s been added to a prohibited list.
