Stenabolic (SR9009)

Stenabolic (SR9009) is a synthetic compound associated with energy metabolism, fat oxidation and physical endurance. In bodybuilding, it is primarily discussed in connection with cutting phases, metabolic efficiency and maintaining training performance during calorie restriction. Although commonly grouped with SARMs, Stenabolic does not activate androgen receptors and is not a true SARM.

Stenabolic acts as a REV-ERB agonist, targeting nuclear receptors involved in circadian rhythm regulation, lipid metabolism and cellular energy balance. Its intended effects include increased fatty acid utilisation, improved metabolic activity and enhanced exercise endurance. SR9009 is also associated with changes in mitochondrial function and energy expenditure, although its biological activity is not limited to REV-ERB signalling. Unlike androgen receptor modulators such as Ostarine or Ligandrol, SR9009 targets metabolic pathways rather than directly stimulating anabolic activity in muscle tissue.
