Most compounds marketed for endurance, fat loss, or body recomposition tend to act on the hormonal system.
SARMs, for instance, activate androgen receptors, which can result in muscle growth â but also carry the risk of hormone suppression. Stenabolic (SR9009), however, belongs to a different class altogether. Instead of affecting your testosterone levels, it works by activating your inner clock and upgrading your cellular power plants: the mitochondria. Letâs break down how this compound functions, and why itâs gaining popularity among athletes, biohackers, and anyone looking to optimize fat metabolism without hormonal downsides.
SR9009 was developed by Dr. Thomas Burris and his team as a REV-ERBα agonist â a compound that binds to and activates this nuclear receptor. REV-ERBα plays a critical role in regulating the circadian rhythm, which in turn governs everything from fat storage and insulin sensitivity to energy usage and inflammation. When Stenabolic activates this receptor, several downstream effects occur:
Unlike SARMs such as Ostarine or Ligandrol, SR9009 does not bind to androgen receptors, which makes it:
This compound is popular among:
Stenabolic works well on its own, but can also be combined with:
Stenabolic represents a new wave of performance enhancers â one that respects the complexity of human metabolism without hijacking your hormones. Its unique mechanism offers targeted benefits for endurance, fat loss, and recovery, making it a versatile addition to almost any protocol. If youâre looking for a non-suppressive, scientifically grounded tool to elevate your metabolic performance â SR9009 might be the mitochondrial edge youâve been missing.
