I am beyond 50, and when I have taken my daily dosage of 1 gram of 1:50 tongkat ali extract, I do double the number of pull-ups, compared to when I am tongkat ali sober.

The strength gain is greatest after the second day of a tongkat ali cycle, and it lasts for about two additional days after I have ended a tongkat ali cycle.

The strength gain is greatest for the kind of exercise that requires muscle strength: pull-ups or running up stairs (an exercise form I personally prefer). There is less benefit from tongkat ali for exercise that is more on endurance, rather than strength, for example distance running over flat terrain.

I think it would be most interesting to do a scientific study on the athletic performance enhancing effect of tongkat ali. Initially, a test utilizing an animal model would be appropriate, e.g. a forced swim test for mice. In such a test, it could easily be determined and measured what effect tongkat ali has on athletic performance.
