Cyanotis arachnoidea Extract (50% Beta-Ecdysterone)
Also known as: Beta-ecdysterone, 20-hydroxyecdysone, Ecdysterone, Cyanotis arachnoidea root extract
Cyanotis arachnoidea is a plant source of beta-ecdysterone, a steroid compound studied for potential muscle-building and athletic performance effects. Evidence in humans remains limited, with most promising data from animal studies and small human trials.
Primary uses
- Muscle building and strength
- Athletic performance
- Body composition
- Endurance support
How it works
- Ecdysone receptor agonist activity (proposed)
- Potential anabolic signaling through non-androgen pathways
- May enhance protein synthesis
Dosage
- Typical range
- 100-600 mg daily (based on ecdysterone content)
- Timing
- Divided doses with meals optimal; timing relative to training not clearly established
- With food
- Take with food to enhance absorption
- Duration
- Research typically examined 8-12 week protocols; long-term safety data limited
- Special populations
- Safety in adolescents, pregnant/nursing women, and those with hormone-sensitive conditions not established
Forms
- Powder (standardized extract)· 70/100
Safety
Common side effects
- Generally well-tolerated at studied doses
- Rare reports of mild GI upset
- No major adverse effects documented in short-term studies
Contraindications
- Individuals with hormone-sensitive cancers (theoretical concern, not proven)
- Pregnant or nursing women (insufficient safety data)
- Those taking hormone medications should consult healthcare provider
Evidence notes
Limited human RCT evidence; most studies are small and show mixed results. Animal data suggests anabolic potential, but human efficacy for muscle gain is not definitively established. Standardized plant extract form (50%) reduces variability but human clinical evidence remains preliminary.
Grade C: Mostly observational or small trials; mechanism is plausible but unproven at scale.
