What is SR9009 (Stenabolic)?
Plain language first. The technical label stays, but it never stands alone.Overview
Sold as a capsule for endurance. The studies behind it injected it into mice, and swallowing it barely gets any into the blood.
SR9009 (stenabolic), a synthetic REV-ERB agonist developed as a circadian and metabolic research tool. Rodent studies report increased exercise capacity and metabolic effects following intraperitoneal administration. Published pharmacokinetic data indicates poor oral bioavailability. No human trial. Prohibited by WADA under S4.4.
What it's used for
Sold orally for endurance, fat loss and metabolic effects.
How does SR9009 (Stenabolic) work?
What it does in the body, and where.SR9009 is not a peptide and not a SARM, though it is sold alongside both.
- 01It targets the body clockREV-ERB proteins are part of the circadian machinery and also regulate metabolic genes. SR9009 was developed as a tool to study that link.
- 02The animal results were strikingMice given it showed increased exercise capacity and metabolic changes, which is the entire basis of the marketing.
- 03Oral bioavailability is the problem nobody mentionsPublished work reports very poor oral bioavailability. A compound sold as an oral capsule, whose effect data comes from injected animals, has a gap between the evidence and the product that no dosing advice can close.
What else is it used for?
Each use below carries its own evidence level. Approved means regulators have cleared it for that purpose. Investigational means it is in trials. Early research means it is being studied and is not established.

What does it cost?
Typical dose and cost, in plain numbers.SR9009 (Stenabolic) is not injected
It is taken by mouth (oral). No human study exists, and the compound never entered clinical development. The published animal work injected it into the abdomen at 100 mg per kg twice a day; oral absorption has never been established, and oral capsules are how it is sold. Prohibited in sport at all times by WADA.

What has happened recently
Not approved for any use anywhere. Prohibited in sport at all times by WADA under section S4.4, metabolic modulators, which names Rev-erb agonists.
Banned in drug-tested sport. Most research peptides are prohibited under WADA's S0 category, which covers any substance with no approval from any regulatory authority for human use. That means a compound can be banned without ever being named on the prohibited list. Check with your own anti-doping authority rather than assuming absence from the list means permitted.
