Muscle-building claims evidence brief
Ecdysteroids such as ecdysterone and turkesterone are plant or insect steroid-like compounds sold for muscle growth. Their marketing often implies anabolic effects without steroid classification.
Human sport evidence is too thin and product identity is too uncertain for muscle-gain recommendations.
Reviews highlight scarce human data and major product-identity issues; turkesterone claims remain unsupported.
Turkesterone and ecdysterone are often marketed together, but evidence and product testing are not interchangeable.
Drug-tested athletes need extra caution because ecdysteroids have been examined in anti-doping contexts.

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.
