A practical reference on REV-ERB agonist: what it is, how it behaves, what the literature reports, and where the honest uncertainties sit.
Reviewed 2026-02-08. Anything still debated is marked as such rather than presented as settled.
At the molecular level, SR9009 binds REV-ERBα and REV-ERBβ and alters their repressive activity on target genes. These nuclear receptors help regulate the circadian clock, lipid synthesis, glucose metabolism, and inflammatory pathways. By changing transcription, the compound can shift the timing or magnitude of downstream metabolic processes in model systems. It does not act through androgen receptors or adenosine receptors, which distinguishes it from several substances sold for athletic performance. Whether the same transcriptional changes occur in humans at tolerable exposures remains an open question because controlled human studies are lacking.
Preclinical reports describe effects on exercise endurance, mitochondrial content, and lipid profiles in rodents, but these findings come from specific experimental conditions. Many studies use high doses or delivery methods that may not translate directly to human use. SR9009 has been reported to have low oral bioavailability and a short half-life, which complicates interpretation of oral dosing studies. It is not established as safe or effective for any indication. Literature discussions often separate its pharmacological mechanism from unverified claims made in fitness and supplement markets.
SR9009 is a synthetic small molecule studied as an agonist of REV-ERB nuclear receptors. REV-ERB alpha and REV-ERB beta help regulate circadian rhythms and metabolic gene expression. In laboratory research, SR9009 has been used to probe how these receptors affect skeletal muscle, liver, and adipose tissue. The compound was identified in academic drug-discovery work and is often described in scientific literature by its chemical name and research code. It is not an approved medicine, and human clinical data remain limited or absent.
SR9009 binds REV-ERB receptors and alters their repressive activity on target genes. This action can change transcription of genes involved in lipid handling, glucose metabolism, and mitochondrial function. In rodent studies, treated animals have shown changes in muscle oxidative capacity and exercise performance, though effects vary by dose, duration, and model. The precise molecular steps connecting receptor binding to whole-body outcomes are still an active area of investigation. Findings in animals do not automatically translate to humans.

Storage conditions for research-grade SR9009 generally involve a freezer at approximately minus twenty degrees Celsius, sometimes lower for long-term preservation. Containers should remain tightly closed and protected from light. Desiccants may be used to limit moisture uptake. Solutions are often stored in aliquots to avoid repeated warming and cooling. Stability data for the compound under various conditions are limited, so laboratories typically follow supplier recommendations and verify performance through periodic analytical checks rather than assuming indefinite stability.
Identity and purity testing for SR9009 commonly uses liquid chromatography coupled with tandem mass spectrometry. This method separates the compound from matrix components and detects it by mass-to-charge transitions, providing sensitive and specific confirmation. Nuclear magnetic resonance spectroscopy can support structural identification, while high-performance liquid chromatography with ultraviolet detection may estimate purity. Because online products labeled as SR9009 may contain other substances or no active compound at all, independent verification is important in research settings. Certificates of analysis are useful but not a substitute for in-house testing.
Laboratory samples of SR9009 are typically supplied as a white to off-white powder. The compound dissolves readily in organic solvents such as dimethyl sulfoxide and ethanol, while its solubility in water is low. Because of this solubility profile, researchers often prepare concentrated stock solutions in an organic solvent before diluting them into aqueous assay buffers. Light exposure, moisture, and repeated freeze-thaw cycles can degrade many small molecules, so handling procedures usually aim to minimize these factors. Purity is commonly checked before use.
Analytical methods for SR9009 typically rely on liquid chromatography coupled with tandem mass spectrometry. The technique can separate the parent compound from related substances and detect low concentrations in biological matrices. Urine and blood are common samples in anti-doping testing, while in vitro studies may use cell culture media. Rapid metabolism and low expected concentrations make method validation important for reliable identification. Exact metabolite patterns can vary by species and are not fully mapped.
Regulatory treatment of SR9009 reflects its investigational status. The compound has no approved human therapeutic indication, and sports authorities prohibit its use. It appears on anti-doping lists as a non-approved substance or metabolic modulator, depending on the list version. Products sold online as research chemicals are not quality-controlled medicines, so their identity and purity can differ from the label. Such products may also contain unlisted compounds, which complicates both testing and safety assessment.
Scientific discussion of SR9009 often separates animal evidence from human anecdote. Rodent studies provide controlled data on endurance, metabolism, and gene expression, but they use specific strains, doses, and treatment durations. Human reports are mostly uncontrolled and cannot establish cause and effect. Open questions include oral bioavailability, tissue distribution, metabolic stability, and long-term effects. Review articles generally call for more rigorous pharmacokinetic and safety research before any clinical use could be considered.
Regulatory agencies have not approved SR9009 for human therapeutic use. It is typically sold as a research chemical with labels stating that it is not for human consumption. The World Anti-Doping Agency prohibits the substance in sport, generally under the category of non-approved substances. Customs and national laws may restrict importation, sale, or possession. Product quality and legal status can vary by country and vendor, and therapeutic claims are not permitted in regulated advertising because the compound lacks approval.
Several misconceptions surround SR9009. It is often described as a SARM, a steroid, or an exercise pill, but its known target is the REV-ERB receptor family. Rodent studies have examined exercise capacity and metabolic markers, yet human outcomes remain unproven. Oral bioavailability appears low in animals, and human pharmacokinetics are not well characterized. Online products may contain impurities or different compounds, so identity and purity testing are important for research use.
Analytical chemists detect SR9009 with liquid chromatography-tandem mass spectrometry, commonly abbreviated LC-MS/MS. Sample preparation may involve protein precipitation, liquid-liquid extraction, or solid-phase extraction before analysis. Laboratories can target the parent compound or its metabolites, depending on the matrix and the purpose of testing. Anti-doping methods require sensitive and specific assays because concentrations in biological samples can be low. Reference standards and validated methods are essential for reliable identification and quantification.

Black Detroiters tended to have far less access to New Deal mortgage support programs such as Federal Housing Authority and Veterans Administration insured mortgages. African-American neighborhoods were viewed by lenders and the federal programs as riskier, resulting—in this period—in much lower rates of homeownership for African-Americans than other residents of the city. The auto industry also gave rise to a large number of high paying management and executive jobs. There were also large numbers of attorneys, advertisers, and other workers who supported the industry's managerial force. These workers already by the 1920s had begun to move to neighborhoods well removed from the industry's factories and higher crime rates. This upper stratum moved to outlying neighborhoods, and further, to well-to-do suburbs such as Bloomfield Hills and Grosse Pointe. Oakland County, north of the city, became a popular place to live for executives in the industry. "By the second half of the twentieth century, it was one of the wealthiest counties in the United States, a place profoundly shaped by the concentration of auto-industry-derived wealth." Public policy was automobile oriented. Funds were directed to the building of expressways for automobile traffic, to the detriment of public transit and the inner-city neighborhoods through which the expressways were cut to get to the auto factories and the downtown office buildings.
As one example, in the 1950s, the Wonder Bread company sponsored the Howdy Doody television show, with host Buffalo Bob Smith telling the audience, "Wonder Bread builds strong bodies 8 ways", referring to the number of added nutrients.

== Non-insulin dependent (type 2) diabetes mellitus == The current releases of the downloadable AIDA software, and AIDA on-line, do not incorporate functions to model endogenous insulin secretion — which takes place in people with non-insulin dependent diabetes mellitus type 2, and healthy subjects without diabetes. Nevertheless, a wide number of people with insulin-treated type 2 diabetes mellitus have reported finding the AIDA diabetes simulator of use for learning about balancing insulin and diet in diabetes. This is because many of the principles of insulin dosage adjustment are remarkably similar in both type 1 and type 2 diabetes mellitus, and even without an endogenous insulin secretion model function, AIDA still can offer realistic simulations (from an educational perspective) for people with non-insulin dependent (type 2) diabetes mellitus. The AIDA developers have published a research paper in 2011 which includes reference to the incorporation of a dedicated function for pancreatic insulin secretion — to be added to a future release of the simulator.
Flunisolide Fluticasone furoate Fluticasone propionate Triamcinolone acetonide Beclomethasone dipropionate Budesonide Mometasone furoate Ciclesonide There also exist certain combination preparations such as Advair Diskus in the United States, containing fluticasone propionate and salmeterol (a long-acting bronchodilator), and Symbicort, containing budesonide and formoterol fumarate dihydrate (another long-acting bronchodilator). They are both approved for use in children over 12 years old.
== Diagnosis == Protein function tests that demonstrate a reduce in chorein levels and also genetic analysis can confirm the diagnosis given to a patient. For a disease like this it is often necessary to sample the blood of the patient on multiple occasions with a specific request given to the haematologist to examine the film for acanthocytes. Another point is that the diagnosis of the disease can be confirmed by the absence of chorein in the western blot of the erythrocyte membranes.
Cases of stigmatism fall into two categories: self-inflicted wounds, which may be either cases of fraud or of unconscious self-infliction, and those that are caused by emotional states ... Self-induced (through autosuggestion) itching and subsequent scratching of which the individual is unaware is likely to occur in suggestible persons if the stimulus is a mental or actual picture of the Crucifixion used during meditation and if the main motive is to receive the stigmata. The motive behind that may be unconscious conflict and a desire to escape from an intolerable situation into invalidism where one's needs are taken care of. It then becomes a case of hysterical conversion reaction. Many cases of stigmatism can be explained as fraud or unconsciously self-inflicted wounds. In his Stigmata: A Medieval Phenomenon in a Modern Age, Ted Harrison suggests that there is no single mechanism whereby the marks of stigmata were produced. Harrison found no evidence from a study of contemporary cases that the marks were supernatural in origin. He concluded, however, that marks of natural origin need not be hoaxes. Some stigmatics marked themselves in attempt to suffer with Christ as a form of piety. Others marked themselves accidentally and their marks were noted as stigmata by witnesses. Often marks of human origin produced profound and genuine religious responses. Harrison also noted that after Saint Francis of Assisi, the stigmata was "seen as a predominantly female experience" with the female-to-male ratio of stigmatics being 7 to 1.

SR9009 is a synthetic REV-ERB agonist used in laboratory research. It is not an approved drug, and its effects in humans are not well characterized. It is often sold as a research chemical under the name Stenabolic.
No. SR9009 targets the nuclear receptors REV-ERBα and REV-ERBβ, not the androgen receptor. This mechanism differs from selective androgen receptor modulators and from exercise mimetics that act on PPARδ.
Published evidence is mainly preclinical, using cell cultures and animal models. Controlled human trials are not well documented in the public literature. Claims about human performance or health effects therefore remain unsupported by robust clinical data.
SR9009 is a synthetic research compound that acts on REV-ERB nuclear receptors. It is not approved for human use and is sold only as a research chemical. Its effects have been studied mainly in cells and rodents.
