miniarnold seems pretty knowledgeable about tongkat.
Firsthand I can say that it increases sex drive, penis and balls increase in size (google a site called testingtongkatali), but it does not give you significant increases in strength, at least not right away, and not in a major way. It is also reported that free T was increased 3x. I have not done blood test so I cannot verify. If we are to believe the info at that site, the increase in T seems reasonable, ie, you can go from 500 to 1000 or so. I would be perfectly happy with this, especially that there are no side effects.
The best thing we can do as a community is test this using before and after blood tests. I will definitely do this personally and report the results. Without this, all this talk is more or less hot air.
Also, I am surprised how little tongkat is present in some supplements. If you're going to try tongkat, I personally feel an effect at 2000mg/day. I don't know what you get at 200mg if anything at all. It costs me about $150 for a 40 day supply at 2000mg/day. tongkatali.org seems to have authorized resellers now that can sell locally much cheaper.
I sent them money via western union last time because it saves me $20 or so. They could have screwed me, but I did receive the order just like when I paid with a credit card.
I can't find the article where they talked about the 1:50 vs 1:200 extracts. But the reason I order the 1:50 is that you get more bang for your buck. The 1:200 is not 4x better, not even 2x better. I strongly recommend you talk to them before getting the 1:200.
So all anecdotal evidence aside, if blood tests prove this stuff is worth the money, I will make it one of my staples.
