Tongkat Ali, also known as Eurycoma Longifolia Jack, Malaysian Ginseng, or Longjack, is a herbal supplement traditionally used in Southeast Asian medicine. It is renowned for its potential benefits in boosting testosterone levels, enhancing sexual health, improving athletic performance, and reducing stress. There are a few different types of Tongkat commonly known as yellow, red, or black. Ours is the yellow Tongkat which is typically regarded as the most potent. Our product is also an extract of the eurycomanones, which is the chemical compound responsible for Tongkat's effects.
