Five human studies of Cordyceps militaris exist, and they disagree
The five tested 321 people aged 16 to 35 at doses spanning twelvefold, 1 to 12 grams. Some found gains in aerobic performance; across the five the results were inconsistent.
What the study found
Every human trial of Cordyceps militaris fits in five studies
The five tested it on 321 people aged sixteen to thirty-five, at daily doses spanning twelvefold, 1 to 12 grams, and most were never registered. Some found gains in aerobic performance or recovery. Across the five, the results were inconsistent.
The caveat · Five results, never combined
The review appraised each study for bias but never pooled them, so there is no combined estimate here, only five separate results. It covers Cordyceps militaris alone, leaving out both the wild caterpillar fungus and the fermented mycelium products that fill much of the retail shelf.
