A Southeast Asian root long used for male vitality.
It does genuinely raise testosterone in men, confirmed by a 2022 meta-analysis — but the effect is concentrated in men who are already low, older, or under high stress, not in healthy young men.
This is the one that genuinely differs from the other testosterone products in this list — but still downgraded, because the trials are small, heterogeneous and often industry-linked.
Weak evidence.
Nothing to do with sleep.
Testosterone in men with a low baseline. If you suspect low testosterone, get a blood test rather than guessing and supplementing.
Commonly used: 200-400 mg per day
