The dose points come from one randomised, placebo-controlled trial of 105 men aged 50 to 70 with low testosterone (PMID 34262417), who took 100 mg or 200 mg a day of a standardised water extract (Physta) for 12 weeks. Total testosterone rose more than on placebo at week 12 with 100 mg, and at weeks 4, 8 and 12 with 200 mg. The trial did not report that 200 mg beat 100 mg directly, so no optimal dose is given. It found no clinically relevant safety changes at either dose, which is why the ceiling is 200 mg. An uncontrolled study of 76 men with late-onset hypogonadism also used 200 mg a day for a month and found testosterone rose (PMID 21671978). A meta-analysis of 5 trials found a significant rise in total testosterone (PMID 36013514) but does not compare doses.
