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.

Reishi contains triterpenoids (ganoderic acids, >130 identified) and polysaccharides (beta-glucans). Ganoderic acids inhibit histamine release, 5-alpha-reductase (DHT reduction), and ACE (angiotensin-converting enzyme). Beta-glucans (1,3/1,6-D-glucan) activate innate immunity via Dectin-1, CR3, and TLR-2 receptors on macrophages, dendritic cells, and NK cells. Reishi modulates the adaptive immune system by promoting Th1/Th2 balance and enhancing regulatory T-cell function. It also supports GABAergic signaling (calming effect), inhibits NF-kB, and modulates gut microbiome composition. Triterpenes support liver function via Phase I/II enzyme modulation.
