Please note that below are public research links showing various studies on Eurycoma Longifolia (Tongkat Ali). We cannot legally guarantee results from any herbal supplement, nor should you expect steroid like results as tongkat ali is NOT a steroid and should NEVER be compared to one. Also, no medicinal claims are being made here, we are simply pointing people to publicly available studies on Tongkat Ali's effects on testosterone and muscle growth, and recommend people take it to MAINTAIN a healthy testosterone level and to help build muscle only, we are not suggesting people take it as an alternative to testosterone replacement therapy as YOU SHOULD NEVER DO THIS NOR SHOULD YOU EVER TAKE ANY HERBAL SUPPLEMENT WITHOUT CONSULTING A QUALIFIED DOCTOR OR REGISTERED HERBALIST FIRST!

Now it is scientifically official: tongkat ali extract can increase muscle muscle growth in men. The British Journal of Sports Medicine reported that in a double-blind placebo controlled scientific trial, the use of tongkat ali extract caused a 5 % increase in lean body mass in the treatment group, while no significant changes were observed in the placebo group. 5 % in 5 weeks is a large improvement, as becomes obvious if one calculates the increase this would mean over a course of a year (5 weeks – 5 %; 52 weeks – 50 %).
