The Primary Active Ingredient Is: Tribulus Terrestris Extract

Tribulus Terrestris extract is a plant‑derived ingredient that helps to support normal hormonal function related to muscle activity and recovery, which is common.

This form is a botanical extract sourced from the Tribulus terrestris plant and is included among other ingredients to support the body's natural hormone production pathways, which helps natural production.

What Does Tribulus Terrestris Extract Do?

Tribulus Terrestris extract helps to stimulate natural hormone production pathways via the hypothalamic‑pituitary‑gonadal axis, aiding endogenous hormone release, which supports muscle function and recovery as part of the product's overall hormone‑support approach.

This formulation also includes other components such as Eurycoma longifolia and fenugreek, which help to support the primary ingredient's role in natural hormone production, and that matters.
