Numerous scientific and clinical studies has been carried out to probe the efficacy of Longjack to increase testosterone levels. As you may notice, there are far more animal studies (specially in mice) than human studies. Mice models are generally used because of their similarity to humans, and this poses many advantages for researchers, to name a few: evaluating possible side effects before their use in humans, ability to control their environment (to isolate the effect of the substance), more flexibility to take and analyse samples and much cheaper cost. These are the reasons why research in animal models is done before human models and tend to be more abundant. However, in some cases the results in animal models doesn’t translate to humans very well, this is the reason why animal models provide a very good reference but you will want to see the actual results in humans before drawing any conclusions. Here I have compiled the most relevant studies, starting with the ones in humans. More and more evidence in humans is becoming available as researches are starting to see the powerful effect of Longjack to increase testosterone levels in men and woman.

In densely shaded greenery in the sweltering hot Malaysian rainforest, I watched three aboriginal men chop a mature Longjack, one of the most powerful plants on earth, out of dense soil. Researching -enhancing plants often puts me in marvelous and remote places. In this instance, the trail led me to Malaysia to research Longjack. It is a popular folk name for Eurycoma longifolia, a medium size slender tree reaching 10 metres in height. Longjack is native to Malaysia, lower Burma, Thailand, and Indonesia. The root is employed as a traditional remedy for the treatment of malaria, high blood pressure, fevers, fatigue, loss of ual desire, and impotence. Longjack enjoys both a long history of traditional use, and a growing body of serious science corroborating its efficacy.
