The product being of French origin, it was fielded to military personnel in Air Force, Foreign Legion and Marine infantry during the 1st Gulf War. Being more efficient than its parent drug adrafinil, it was deemed combat-worthy by French Ministry of Defense in 1989 and subsequently administered to personnel by their officers under the name "Virgyl", in order to improve a unit's operational tempo. The test took place before the introduction of modafinil as medication, and the personnel involved was not informed of the product's nature.
