Stenabolic (SR9009)
A REV-ERB agonist (stenabolic) often grouped with SARMs although it acts on circadian metabolism rather than androgen receptors. It has been studied mainly in rodents.
- Half-life
- 4 h
- Out of system
- ~20 h
- Route
- Oral
- Level
- Intermediate
Short-acting — protocols usually dose daily. After the last dose, roughly 97% has cleared in ~20 h (five half-lives) — the window that matters for washouts, bloodwork and surgery.
What Stenabolic (SR9009) is used for
- Rodent studies showed increased endurance, fat loss and improved metabolic markers
- Acts on the circadian clock to shift metabolism toward energy expenditure
How it's typically used
Reported user ranges are around 10 mg daily split into doses, despite poor absorption.
What to watch for
- Very poor oral bioavailability means human oral dosing may do little
- No human trials exist, so benefits are unproven outside animal models
- Not approved for human use; an unapproved research chemical banned in sport
About SARMs
- What they are
- Selective androgen receptor modulators — oral compounds designed to hit muscle and bone androgen receptors while sparing prostate and skin. None is an approved medicine anywhere.
- How they're run
- Taken orally once a day, typically in 8–12 week blocks.
- What to watch
- The "non-suppressive" reputation is marketing: most suppress natural testosterone, and several are liver-toxic. Independent testing repeatedly finds products containing something other than the label. Bloodwork before and after is the minimum.
