Tongkat ali (LongJack)

Wondering if anyone here has used this supplement. I'm looking for a way to increase testosterone naturally and there have been small studies indicating that this boosts testosterone and lowers free testosterone. The benefits stated for this root extract seem to be impressive. It increases testosterone through the leydig cells in the testes, it overrides your body to pump out more testosterone than your baseline t level. Benefits through increased t include more energy, increased muscle mass, better fat displacement, better mood and more libido. This all sounds too good to be true so just wondering if anyone else has tried this. I am ordering some nonetheless to try it out, who knows could be good for hair as well!
