What is it
Turkesterone is an ecdysteroid, a plant steroid found in Ajuga turkestanica and related plants, marketed as a 'natural anabolic' for muscle growth. Despite heavy promotion in fitness circles, it is not a hormone in humans and has essentially no rigorous human clinical evidence behind its muscle-building claims.

muscle growth / strength
Mechanism onlyTurkesterone's anabolic reputation comes from cell and rodent studies suggesting effects on protein synthesis, not from controlled human trials, of which there are essentially none specific to turkesterone. The broader ecdysteroid literature in humans is sparse and unconvincing, and many marketed products may not even contain the labeled amount. There is no reliable human evidence that it builds muscle or strength.
Bottom line: A heavily marketed but unproven 'natural anabolic' with no credible human evidence of benefit.
Evidence is mixed
Promotional claims and preclinical data conflict with the near-total absence of human trials demonstrating benefit.
