Product Description

Black Jack is a herbal supplement made to optimise men’s immunity, performance and sexual health. It contains a balanced composition of 2 types of Tongkat Ali, in its layman 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.


Eurycoma longifolia (White Tongkat Ali)

Eurycoma longifolia is a medicinal plant commonly called Tongkat Ali and “Malaysian ginseng.” Tongkat Ali roots are a traditional “anti-aging” remedy and modern supplements are intended to improve libido, energy, sports performance and weight loss. It is also a folk remedy for malaria. Previous studies have shown properly-standardized Tongkat Ali to stimulate release of free testosterone, improve sex drive, reduce fatigue, and improve well-being. It can increase testosterone level in men by up to 500%.

Polyalthia bullata (Black Tongkat Ali)

Black Tongkat Ali is less common than normal tongkat ali. However, its healing efficacy is much better than white Tongkat Ali. Studies have revealed that some natural compounds contained in Tongkat Ali can increase male virility and sexual performance. In addition, pharmacological studies on compounds Saponosides and Glycosides in Black Tongkat Ali show that they can help to:

  • Improve blood circulation
  • Increase testosterone level
  • Boost energy and stamina
  • Promote spermatogenesis
  • Assist sexual dysfunction and impotence
  • Control cholesterol levels and hypertension




Due to the herbal nature of this supplement, please consult your doctor before taking any supplements:

    • Preferably taken after meals
    • Consume 2-4 capsules per day depending on your condition. If taking 4, space out to 2 capsules in the morning & 2 capsules at night.
    • For better results, continue for at least 1-3 months.

*Black Jack will not give an immediate effect as the formula is 100% extracted from 2 types of Tongkat Ali without any additional chemicals such as sexual stimulants. It is NOT a viagra.
