7-Keto-DHEA

7-Ketodehydroepiandrosterone (7-keto-DHEA,7-oxo-DHEA), also known as 7-oxoprasterone, is a prohormone produced by metabolism of the prohormone dehydroepiandrosterone (DHEA). 
7-oxo-DHEA is even more effective than DHEA for inducing heat production (thermogenesis). Because dieting is usually accompanied by reduced resting metabolic rate, obese persons may benefit from using 7-oxo-DHEA when dieting due to increased metabolic rate. 
7-Keto-DHEA is not directly converted to testosterone or estrogen, and has thus been investigated as a potentially more useful relative of DHEA. Researchers have raised concern that supplements may trigger positive tests for performance-enhancing drugs.
The World Anti-Doping Agency lists 7-keto-DHEA as a prohibited anabolic agent. The FDA has proposed that it be banned from use in compounded drugs.
