Eurycoma Longifolia Jack – Sex Drive And Testosterone

Eurycoma has proved to be a reasonably effective libido booster, however when taking its testosterone boosting benefits into account, the jury is most decidedly out..

There have been tests that have shown some increases in testosterone in subjects who were hypogonadic..and one test carried out in Malaysia saw 320 men diagnosed with late onset and extreme hypogonadism treated with 200mg Eurycoma Longifolia Jack in a soluble form.

Over a period of a month most subjects saw an increase in serum testosterone averaging 46% – read study results here


In safe doses, it is accepted that Eurycoma could have some benefits to any man suffering the effects of low testosterone, especially with regard to libido and erection problems..

It does however seems to be more effective when patients are suffering with extreme clinical hypogonadism ( 6umol/L)

It does appears to be less likely to be effective when levels are only moderately low.
