Desert plant extract containing echinacoside and acteoside that support testosterone via LH stimulation, enhance neurogenesis via BDNF upregulation, and improve gut microbiome composition. Traditional use as 'desert ginseng' for vitality and cognition.
Fadogia agrestis stem extract contains saponins and alkaloids that appear to increase luteinizing hormone (LH) release from the anterior pituitary, stimulating Leydig cell testosterone production. Animal studies suggest it may also have direct effects on testicular steroidogenic enzymes and may increase testicular weight. The saponin content may modulate gonadotropin-releasing hormone (GnRH) pulse frequency. The aphrodisiac effects are likely mediated through increased testosterone and possibly direct effects on dopaminergic and nitrergic pathways.
