Turkesterone is an extract from the plant Ajuga turkestanica, which resembles milk thistle and thrives in Siberia, Asia, and Eastern Europe. It is a highly concentrated type of ecdysterone, a category of natural compounds with a chemical structure and effects similar to androgens, but with milder action and much higher safety profiles. In addition to supporting male hormones and recovery from weight training, turkesterone is also believed to promote liver health.
