SR9009 also known as Stenabolic is a research drug that was developed by Professor Thomas Burris of the Scripps Research Institute as an agonist of Rev-ErbA (i.e., increases the constitutive repression of genes regulated by Rev-ErbA) with a half-maximum inhibitory concentration (IC50) = 670 nM for Rev-ErbAα and IC50 = 800 nM for Rev-ErbAβ.
Some companies are selling SR9009 online for human use as a 'research chemical.' In an email correspondence, the developer, Prof. Burris said of SR9009's use in humans: "I just recently found out that someone is selling SR9009 in a manner that is "supported" for human use in bodybuilding. I agree with your comments. The drug does in fact alter the circadian rhythm (in mice) and we would need to assume in humans – and we don't know if it is beneficial or detrimental at this point. SR9009 was designed as a "tool" molecule to determine if we should pursue making more drug like compounds that could be used to treat disease. Of course, the data is supportive of going forward – and we are designing better compounds – but the issue is that SR9009 has several issues that make it unsuitable for human use. Firstly, it has no oral bioavailability. I know the company selling this is indicating taking it orally is ok – but it doesn't even get into the blood. At this point that is probably not a bad thing since the drug has not been evaluated in appropriate toxicology assays to determine if there are issues like inducing disease (cancer as you indicate or others). There is going to be exposure to the gut and that is not necessarily good since we don't know the effects as of yet. SR9009 has some functional groups that are known to have potential toxicology liabilities and it would never be developed as a drug. It was ok as a "tool" to figure out if we should continue to spend money and effort to get better drugs – but we had to design these "bad" functional groups out since they are know to have toxic effects in humans. So bottom line – I would never recommend using this compound at this point. That being said – we are still working on improved compounds with one of the potential uses being sarcopenia – loss of muscle and strength due to aging."
SR9009 is currently on the World Anti-Doping Association list of prohibited drugs.
