Hormone-related claims evidence brief
Cistanche is a desert plant extract sold for testosterone, vitality, fatigue, and recovery claims. It is common in modern hormone-support stacks despite limited human data.
Cistanche has emerging human data, but testosterone, recovery, and muscle claims are still too early and product-specific for recommendation.
Early RCTs report muscle or locomotive-function signals; testosterone and recovery claims remain preliminary.
Species, extract standardization, and phenylethanoid glycoside content matter. Cistanche deserticola and Cistanche tubulosa are not interchangeable.
Independent training trials, safety replication, identity testing, and contaminant testing are still needed.

The score reflects evidence that the supplement does its stated job. Some jobs are direct, such as strength, endurance, or recovery; others are indirect, such as sleep, mood, appetite, or health support. A real effect can still receive a cautious practical rating when dose, safety, product quality, or audience fit remain uncertain.
Send the disputed claim, source link, and why it changes the practical verdict. Corrections that materially affect the claim, dose, caveat, or rating are prioritized.
