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.
Maca (Lepidium meyenii) contains unique macamides and macaenes (fatty acid derivatives), glucosinolates, and alkaloids. Unlike most adaptogens, maca does not directly affect testosterone, estrogen, or cortisol levels in blood. Instead, it appears to work as a 'hormonal normalizer' by acting on the hypothalamic-pituitary axis, modulating GnRH pulsatility and improving receptor sensitivity. Macamides interact with the endocannabinoid system (FAAH inhibition) and may modulate GABA and opioid pathways. Maca improves sexual function and desire through mechanisms independent of direct hormone elevation — likely central nervous system pathways.
