The evidence in words
The verdict
For libido, Tongkat Ali earns evidence grade C (small effect, mixed consistency) — the evidence is limited or mixed. Subjective
How it might work
It appears to lower sex-hormone-binding globulin (freeing testosterone) and reduce cortisol, plausibly improving the testosterone-to-cortisol ratio under stress.
How to use it
200–400 mg/day of a standardized extract; assess over 4–8 weeks.
Safety & cautions
Generally tolerated; long-term safety and heavy-metal contamination of poor products are concerns — buy tested brands.
Bottom line
If you're going to trial a testosterone-support herb, this is the one — 200–400 mg standardized, most likely to help if you're stressed or older. Gate the trial on a lab and buy a tested product.
How it is used
As the entry records it, from the studies it summarises. Not a recommendation for you — doses that suit a trial population may not suit you.
