Was a study conducted on the purified fraction of ZNZ Tongkat Ali?
The in vitro results from this study showed that extract containing eurypeptides significantly increase CYP17 enzymes compared to the positive control, suggesting that more of the CYP17 enzyme is produced to metabolize the Pentenelone to yield more testosterone and pprogesterone. Low amounts of Pregnenolone and 17-OH pregnenolone compared to control also confirm that more CYP17 is activated to convert pregnenolone and 17-OH pregnenolone into progesterone and testosterone. Pregnenolone is also a precursor for the synthesie of pheromones. The study showed that eurypeptides influenced the synthesis of pheromones by significantly increasing An alpha-a pheromone that plays an important role in communication, psychological and sexual behavior in humans, confirming the aphrodisiac aspects of ZNZ Tongkat Ali.
