Headline Finding

Citrulline review: common acute dose is 8 g CM or 3-4 g L-citrulline about 1 h pre-exercise.

Important Caveat

Do not treat as proven for hypertrophy or long-term strength gains.

How To Read This Rating

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.
