SR9009, also known as Stenabolic, is a research drug that was developed by professor Thomas Burris of the Scripps Research Institute as an agonist of Rev-ErbA (i.e., increases the constitutive repression of genes regulated by Rev-ErbA)[1] with a half-maximum inhibitory concentration (IC50) = 670 nM for Rev-ErbAα and IC50 = 800 nM for Rev-ErbAβ.[2]

Activation of Rev-ErbA-α by SR9009 in mice increases exercise capacity by increasing mitochondria counts in skeletal muscle.[3]

Abuse of SR9009 has been reported within the bodybuilding community, resulting in SR9009 being placed on the World Anti-Doping Agency list of prohibited drugs. SR9009 and the related SR9011 drug are described as "Hormone and Metabolic Modulators".[4][5]
