My Tongkat Ali experiment (2024 experiment)

Did 20 caps of the 10% eurycomanone extract get me over 2000ng/dl?

My Tongkat Ali experiment (2024 experiment)

In March 2023 I decided to experiment with high dose Tongkat Ali.

The reason was because the research suggested that Tongkat Ali can increase testosterone in a dose-dependent manner.

An in vitro study showed that eurycomanone (one of the active ingredients in Tongkat Ali) increased testosterone in a dose-dependent manner (left part).

An animal study showed that Tongkat Ali with 14% eurycomanone increased total and free testosterone in a dose-dependent manner.

In humans, Tongkat also seems to increase testosterone in a dose-dependent manner.

It’s even been shown to increase the amount of Leydig cells (where testosterone is being produced).

So I thought I was all set. In vitro, animal and human research suggest that Tongkat can increase T in a dose-dependent manner.

I thought I was going to be the first guy to boost his testosterone over 2000ng/dl naturally by mega-dosing Tongkat.

Nootropics depot reached out to me and asked if we could collab, so I decided this was prime time to use their 10% eurycomanone Tongkat Ali extract for my experiment.

I thought I’d kick it off at 10 caps for 4 weeks. But in the 4th week, I decided to go up to 20 caps.

Over 9000 here I come!

After 4 weeks I tested:

  • Complete blood count

  • ESR (marker of long-term oxidative stress)

  • Liver panel (ALT, AST, bilirubin, GGT, ALP, LDH, etc.)

  • Lipid panel

  • hsCRP (short-term marker of inflammation)

  • Cortisol

  • Estradiol (Tongkat is an aromatase inhibitor, so a lot of people thought I was going to tank my estradiol)

  • Total and free testosterone

  • LH

  • DHEA-S

After the 4 weeks, I dropped the dose to 5 caps and used that for another week before retesting my testosterone again.

Preface

In 2023 I tested my testosterone and it was 1256ng/dl. So I decided to try 250mg and then 500mg of testosterone injections per week to see if I’d notice additional benefits (I didn’t. Like zero, except harder muscles).

I stopped the T injections and 3 weeks later tested my T, so that I could start with the Tongkat experiment.

My testosterone with 500mg/w injections was 2400ng/dl, which then dropped to 326ng/dl after 3 weeks. Then I started the Tongkat.

Here are my results. 👇
