This New Tongkat Ali Study Goes Beyond Raising Testosterone
"A few years ago, I took 600 milligrams per day, which was a lot, and my testosterone more than doubled. I'm not even kidding. It wasn't super high to begin with, and it was like in the 250s, and it went up to around 500. But it doubled so fast, and there was so much DHT conversion, that I actually noticed I had a little bit of hair thinning."
The speaker shares firsthand experience with Tongkat Ali supplementation, reporting his testosterone levels doubled from the 250s to around 500 ng/dL on 600 milligrams daily, though the rapid increase caused noticeable hair thinning from DHT conversion. He subsequently lowered the dose while maintaining testosterone gains, suggesting most users need far less than typical recommended dosages. This personal revelation adds context to why the compound works so effectively even at lower doses.
