They are powerful natural compounds that have been shown in peer-reviewed clinical research to increase free testosterone [1], improve mood and lower cortisol stress levels [2]. It is one of the most potent testosterone boosters on the planet.

However for it to be really effective the root must be concentrated and aged for 10 years. This makes its expensive and many dodgy testosterone supplements use fake or un-aged Tongkat Ali from China. In fact, one 2015 study showed that 41% of popular Tongkat Ali products contained no Tongkat Ali at all![3]

Our Tongkat Ali is genuine, aged for 10 years and tested in US laboratories for purity and strength - you can view our certificate of authenticity and lab test results here.
