Performance

Turkesterone

Plant ecdysteroid sold for muscle gain, but human evidence for turkesterone itself is minimal and unconvincing.

01May support lean mass gains
02May improve strength output
03May support training recovery

Chemical Forms

Recommended
  • Standardized Ajuga turkestanica extract
Avoid
  • Unstandardized Ajuga powder
  • Proprietary ecdysteroid blends with undisclosed turkesterone content
  • Products without third-party identity testing
Expert Note

There is no clinically validated best form because turkesterone itself lacks solid human trials. If someone uses it anyway, a standardized extract with verified identity is preferable to generic plant powder or blended products that may not contain the labeled amount.

Protocol

Amount
500-1000 mg
Frequency
Once daily
When
Any time of day with food may improve tolerance, but no timing strategy is proven.

Safety & Limits

Upper Safe Limit
No established UL; long-term human safety data are insufficient.
Cycling
If used despite limited evidence, limit self-experiments to 8 weeks, then stop and reassess.

Contraindications

Pregnancy or breastfeeding — insufficient safety data
Hormone-sensitive conditions — theoretical concern from ecdysteroid signaling, though unproven in humans
Children and adolescents — no meaningful safety or efficacy data
Use alongside multiple unregulated muscle-building supplements — higher adulteration and interaction risk

Synergies

Whey protein

Adequate protein is required for any meaningful increase in muscle protein accretion, so protein sufficiency matters more than turkesterone itself.

Creatine

Creatine has strong evidence for strength and lean mass, making it a more evidence-based foundation than turkesterone for performance goals.

Avoid Combining With

  • ✕Products with proprietary blends (obscure actual dose and identity)
  • ✕Low protein intake (limits any plausible muscle-building effect)
