Tonkat Ali, another very notable one. The main mechanism that people seem to agree on that it does do suppression of SHBG to some extent, as well as the upregulation of steroidogenesis intratesticularly. So like locally upregulating, I believe, a steroidogenic acute regulatory protein that basically incorporates cholesterol into the mitochondria to actually undergo these enzymatic cleaving sequences that result in the production of testosterone locally. So it seems to like help upregulate the process that actually enzymatically spits out testosterone essentially locally. So that one seems to work well for individuals who have high SHBG levels or potentially higher estrogen levels than they, you know, it's otherwise fixable via basic lifestyle changes and whatnot. I think it's for people who have adequate, everything looks on paper to be sufficient, but their SHBG might be a bit high or they could use a little bit of a boost. This seems to work to the tune of 100 to 200 nanograms per deciliter for some people.
