Hormone-related claims evidence brief
Fadogia agrestis is an herbal extract popular in testosterone-support products. It is commonly promoted for testosterone, libido, strength, and muscle gain despite very limited human evidence.
Fadogia is popular in testosterone stacks, but there are no convincing human trials for testosterone, strength, hypertrophy, or performance.
Key hormone claim comes from rat data; chronic rat studies also raise testicular, liver, and kidney safety concerns.
Human dose, effective range, and long-term safety are not established. Product extracts also vary widely.
This is a high-hype, low-evidence entry with unusually poor human safety data for a mainstream testosterone-stack ingredient.

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.
