How does SD-200 Tongkat Ali (Eurycoma Longifolia Jack) supplement works?
The way SD-200 works is to stimulate the production of testosterone from your Leydig cells and at the same time increasing the amount of free testosterone. During your teenage years, it is the increase in testosterone production that spurs the growth of your male genitals, sperm production and sex drive along with bone and muscle growth. The increase in testosterone production will have the exact same effect for you (but without the teenage angst!).
