Black Jack is an herbal supplement made to optimize men’s immunity, performance, and sexual health. It contains a balanced composition of 2 types of Tongkat Ali, in its layman’s terms: White and Black Tongkat Ali. Both sound similar but they have their own unique potent qualities and work together to give the best results. Originating from Southeast Asia, Tongkat Ali has also been increasing in popularity over the years, especially in Western parts of the world.
