You pose a good question.
The reason that I take the tonkat twice a day is that the effects are cumulative as it stays and builds in the system . Also, I am addicted to the “fluff”. My research into tonkat revealed the term “tonkat penis” which was in reference to experiments with rats that were given high daily doses of the herb and permanent enlargement of their genitals resulted. Unfortunately, the relative doses that would be required for humans would not be tolerated by our systems.
However, tonkat does produce a unique fluff. Not a semi like cialis, but a kind of darker, swollen, heavier look and feel, the testicles are a bit larger and feel heavier, at least in my experience.
I agree with what someone else mentioned about mental clarity while taking tonkat. Also, the point about being more attentive to ones mate and an increase in their perceived attractiveness seems to be true.
There are many herbs and pharmaceuticals that will do what they are purported to do, when we manage the doses and cycles correctly for our individual physiology, as you may know. I have had positive results with almost all that I have experimented with, and wouldn’t have any problem championing any of them in a debate of which is best. Tonkat just happens to be my favorite…so far!
