🧪 Formulation Notes
Eurycoma longifolia Jack is the scientific name for what is more commonly known as Tongkat ali, Malaysian ginseng, or longjack. Although every part of the Tongkat Ali plant is used by traditional herbalists of Southeast Asia, its root is especially prized. Tongkat Ali is known to possess various naturally occurring bioactive compounds, including eurypeptides and saponins. NOW TestoJack 300 delivers 300 mg non-GMO Tongkat ali extract per capsule.
