Horn Deodorant is a deodorant brand in Grand Theft Auto IV. The deodorant's motto is "Bring out the Beast". Horn is a parody of Axe men's deodorant. The Horn is advertised to contain pheromones and to have an effect that it lasts 48 hours. The Horn has four advertisements on the radio, including one in Russian and one in Spanish. A prominent Horn billboard can be seen at Star Junction that periodically sprays green dust into the air.
