I have been looking at stuff to take during PCT to help with libido and have found that Tribulus helps but it seems Tongkat Ali has some good reviews...
Both are a natural herb so I think I am gonna get my hands on some Tongkat Ali.
Here is something I found about it:
No doubt... tongkat ali is the most powerful herbal substance as far as it goes with stimulating LH production, and it also has a particularly useful to steroid users property in that it reduces SHBG's which essentially makes you less responsive to higher levels of testosterone. Tongkat ali in just a couple weeks of use can lower your SHBG's as much as 70% which results in huge increases in free available testosterone, very important when you are in recovery and this can preserve/save your on-cycle gains in a very big way.
Tongkat ali can be used long term, whereas Tribulus has been shown to only stimulate your testosterone production for about 10 to 14 days, then it looses its effectiveness. On the other hand tongkat continues to raise the bar higher and higher in time as you continue using tongkat. Many doctors now refer to tongkat ali as being "herbal HCG" or herbal clomid but its perhaps better more like clomid this HCG because it forever stimulates your HTPA and never shuts it down like tribulus or HCG can.
