Turkesterone

Also known as 11,20-dihydroxyecdysone.  Turkesterone is an ecdysteroid and analog of 20-hydroxyecdysone isolated from Ajuga turkestanica, a medicinal plant grown in Uzebekistan. Turkesterone is an ingredient in a number of bodybuilding supplements, although there is only limited Russian research to support its use for building muscle or improving athletic performance.
