The tongkat ali 1:200 extract was developped by Sumatra Pasak Bumi (tongkatali.org) more than 20 years ago, and it had a major impact on the sexual enhancement community and many aging men.
No other herbal supplement has been faked to the same extent. If you see any website claiming to sell 1:200 tongkat ali extract, write to tongkatali.org and ask them whether they are an authorized reseller. Feel free to ask about me, too. I only sell genuine products, no Chinese copies that have no effect on libido and have killed a good number of people, including the US. Just google for caverflo.
Anyway, life progresses, and so does sexual enhancement. Plain 1:200 extract is no longer the most effective option for improved testosterone and libido.
Because now there is tongkat ali in combination with butea superba. Butea superba also is a testosterone booster, but it elevates not just free testosterone but also dihydrotestosterone. That's a more potent testosterone more directly responsible for sexual desire.
You can just google for: butea superba hyperandrogenemia
You will find scientific resources referring to the extreme libido that butea superba can cause.
But rather than taking the butea superba alone, it's still better to blend it with the established 1:200 tongkat ali extract of Sumatra Pasak Bumi. This is the new gold standard of herbal libido enhancement.
I sell the Thai Testosterone - Libido Formula of tongkatali.org, but at a lower price.
I also sell the 1:200 tongkat ali and the butea superba separately, in bottles of 100 caps and as pouches of 75 grams.
