§ 01 — EFFECTS
6 documented
Increased endurance capacity
Enhanced fat oxidation
Reduced lipid synthesis
Altered circadian gene expression
Anti-inflammatory effects
Modulated glucose metabolism
§ 02 — RISKS
No human safety data exists; all findings are from animal and in vitro studies
REV-ERB-independent off-target effects on cell viability and metabolism raise unknown long-term risks
Short half-life requires frequent dosing, increasing cumulative exposure
Potential disruption of natural circadian rhythms with chronic use
WADA-prohibited substance; athletic use results in disqualification
Hepatic and renal effects unknown in humans
§ 03 — INTERACTIONS
Interaction data not yet available for this compound.
§ 04 — SCIENCE

SR9009 was developed by Burris et al. and showed increased exercise endurance and fat loss in mouse models, generating significant grey-market interest. Animal studies demonstrate cardioprotective effects under pressure overload, anti-tumor activity in small-cell lung cancer and prostate cancer, and anti-inflammatory effects in sepsis-induced lung injury. Critically, a 2019 PNAS study showed SR9009 exerts REV-ERB-independent effects on cell proliferation and metabolism, meaning some observed benefits may not reflect REV-ERB agonism. No human clinical trials have been published; all efficacy and safety data derive from in vitro and animal models. The compound is on the WADA Prohibited List and has no approved medical use.
