The Active Ingredient Is: Tongkat Ali Extract (LJ100)

Tongkat Ali extract LJ100 is a herbal extract derived from Eurycoma longifolia Jack and used for its bioactive profile. This standardised extract contains 22% eurypeptides and 40% glycosaponins, providing key components associated with its physiological effects.

This form is sourced from Tongkat Ali and is used to support the body’s normal hormonal and vitality processes, reflecting its traditional use and scientific focus on its bioactive constituents.

What Does Tongkat Ali Extract Do?

Tongkat Ali extract participates in supporting the body's hormonal balance and energy-related processes, and is involved in interactions along the hypothalamic-pituitary-gonadal axis as described in research contexts.

Studies indicate potential improvements in testosterone-related parameters and mood with LJ100, supporting energy and stamina when used within validated ranges, according to clinical investigations led by Dr. Leisegang of Kaunas University.
