Everything below concerns LC-MS/MS. We keep the language plain, cite what the science says, and separate well-supported claims from open questions.
Last reviewed on 2026-06-23. Where a claim depends on a specific study, the study is described rather than over-claimed.
At the molecular level, SR9009 binds the ligand-binding domain of REV-ERB and strengthens recruitment of corepressor proteins such as NCoR and HDAC3. This increases repression of target genes, including Bmal1 and other clock-controlled and metabolic genes. In rodent studies, such changes have been linked to altered lipid handling, glucose metabolism, and energy expenditure. The precise chain of events between receptor binding and whole-body effects remains an active area of research. Findings in animals do not automatically translate to humans.
Laboratory studies often administer SR9009 by injection because oral absorption appears poor in rodents. Reported pharmacokinetic properties include rapid metabolism and low systemic exposure after oral dosing. Human pharmacokinetic data are sparse, so absorption, distribution, metabolism, and excretion in people are not well defined. Some research explores related REV-ERB compounds with improved drug-like properties. Regulatory approval for any REV-ERB agonist as a human medicine has not been granted to date.
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.
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.

Stability depends on physical form, temperature, light exposure, and solvent. Solid SR9009 is generally stored cold and dry, with protection from light to limit degradation. Dimethyl sulfoxide stocks are common for laboratory work, but repeated freeze-thaw cycles can reduce compound integrity. Aqueous solutions may be less stable than organic stocks, and the ethyl ester in the structure can be susceptible to hydrolysis under certain conditions. Researchers typically validate storage conditions and recheck purity before quantitative experiments, especially when using archived material.
Regulatory treatment of SR9009 varies by country and region. It is not approved as a pharmaceutical, and several jurisdictions restrict its sale for human consumption. Some authorities classify it as a research chemical, a prescription-only substance, or a prohibited performance-enhancing agent in sport. Purchasers may encounter certificates of analysis, but these documents do not guarantee identity, purity, or legality. In research settings, institutional safety reviews and controlled procurement help ensure that materials are handled under appropriate oversight. The absence of harmonized rules means that legal status can change and requires verification.
Analytical identification of SR9009 typically relies on liquid chromatography coupled with tandem mass spectrometry. In biological samples, researchers first separate the compound from matrix components using protein precipitation, liquid-liquid extraction, or solid-phase extraction. High-performance liquid chromatography with ultraviolet detection and nuclear magnetic resonance spectroscopy can support structural confirmation of reference materials. Because SR9009 is a small, relatively lipophilic molecule, reverse-phase columns and acidic mobile phases are common. Laboratories often include isotope-labeled internal standards to improve quantification and to correct for ion suppression.
In June 1985, the state indicted 22 senior VCA and UDF activists on treason charges for their alleged role in instigating the uprising; the Delmas Treason Trial ultimately resulted in 11 convictions, four on the original charge of treason and seven others for terrorism. The large number of arrests effected during the uprising also resulted in other trials (such as that of the Sharpeville six) and, more commonly, in lengthy detentions without trial. In December 1987, the Weekly Mail counted that, since the outbreak of the uprising in September 1984, 44 black people had been sentenced to hang for related killings; five of them had already hung.
Harmonized analyses of measurements from residential buildings have shown substantial variation in indoor CO2 concentrations according to ventilation type and other building and environmental characteristics. Guidelines and standards use CO2 concentrations as an indicator of indoor air quality and ventilation. The National Institute for Occupational Safety and Health (NIOSH) considers concentrations above 1000 ppm to be a marker suggesting inadequate ventilation. Guidance for schools in the United Kingdom has used concentrations of 800 ppm or lower as an indicator of good ventilation. Thresholds used to characterize indoor air quality vary among standards and guidance documents. In occupied, poorly ventilated spaces, CO2 concentrations can rise substantially above outdoor levels within a relatively short period. The rate of increase depends on factors such as room volume, occupancy and ventilation. Measurements in enclosed office spaces have shown that concentrations can rise from approximately 500 ppm to above 1000 ppm within tens of minutes after ventilation is stopped.
Defects of red blood cell membrane production (as in hereditary spherocytosis and hereditary elliptocytosis) Defects in hemoglobin production (as in thalassemia, sickle-cell disease and congenital dyserythropoietic anemia) Defective red cell metabolism (as in glucose-6-phosphate dehydrogenase deficiency and pyruvate kinase deficiency) Paroxysmal nocturnal hemoglobinuria (PNH), sometimes referred to as Marchiafava-Micheli syndrome, is a rare, acquired, potentially life-threatening disease of the blood characterized by complement-induced intravascular hemolytic anemia.

By July 2019, this has not happened, according to The Record. Critics raised concerns that Hydro One will not experience stability as Premier Ford's government has a "record of reaching in to exert control." On March 21, 2019, Minister Rickford tabled Bill 87, the Fixing the Hydro Mess Act, which was given royal assent on May 9. Bill 87 overhauled the Ontario Energy Board and eliminated the Liberal's 2017 Fair Hydro Plan which the PC's said would save $442 million. The Liberal Plan "subsidized electricity with borrowed money" in response to a "public outcry over soaring hydro rates, particularly in rural areas." The Liberals created the Ontario Power Generation Inc (OPG Trust) as the Financial Services Manager to manage the debt. Bonnie Lysyk, the Auditor General, released a special report on October 17, 2017, which said the "structure of the plan" was in violation of the provincial government's accounting rules. She said that the Plan, which committed the government to discount consumer electricity rates for ten years, would cost the province "$21 billion in interest over the next 30 years." The 2017 AG report said that it would cost $4 billion more on the $18.4 billion loan to use the Ontario Power Generation (OPG Trust) than if the province took out the loan because the province would have a lower interest rate than the OPG Trust. The Ford government said that they would maintain [the] 25 per cent time-of-use rates, that was part of the Liberal's Fair Hydro Plan.
=== Notable cases === 1994: Lucien Bouchard, future premier of Québec, Canada, who was infected while leader of the federal official opposition Bloc Québécois party, lost a leg to the illness. 1994: A cluster of cases occurred in Gloucestershire, in the west of England. Of five confirmed and one probable infection, two died. The cases were believed to be connected. The first two had acquired the Streptococcus pyogenes bacteria during surgery; the remaining four were community-acquired. The cases generated much newspaper coverage, with lurid headlines such as "Flesh Eating Bug Ate My Face". 1997: Jeff Moorad, former agent and partial owner of the San Diego Padres and Arizona Diamondbacks, contracted the disease. He had seven surgeries in a little more than a week and later fully recovered. 2004: Don Rickles, American stand-up comedian, actor, and author, known especially for his insult comedy, contracted the disease in his left leg. He had six operations and later recovered. The condition confined him in his later years to performing comedy from a chair. 2004: Eric Allin Cornell, winner of the 2001 Nobel Prize in Physics, lost his left arm and shoulder to the disease. 2005: Alexandru Marin, an experimental particle physicist, professor at MIT, Boston University, and Harvard University, and researcher at CERN and JINR, died from the disease. 2006: Alan Coren, British writer and satirist, announced in his Christmas column for The Times that his long absence as a columnist had been caused by his contracting the disease while on holiday in France. 2009: R. W.

Aang, in the animated series Avatar: The Last Airbender and The Legend of Korra was vegetarian. According to the show's creators, "Buddhism and Taoism have been huge inspirations behind the idea for Avatar." As shown in "The King of Omashu" and "The Headband", a notable aspect of Aang's character is his vegetarian diet, which is consistent with Buddhism, Hinduism, and Taoism. In the Brahmajala Sutra, a Buddhist code of ethics, vegetarianism is encouraged. Other fictional characters who are vegetarians include Count Duckula in Count Duckula, Beast Boy in Teen Titans and Teen Titans Go!, Lenore in Supernatural, and Norville "Shaggy" Rogers in the animated series What's New, Scooby Doo?. Before the latter animated series, Shaggy was known for having an "enormous appetite" earlier in the Scooby-Doo franchise. The decision to make Shaggy a vegetarian occurred after his voice actor, Casey Kasem, convinced the producers to do so, since he was a vegan who supported animal rights and opposed factory farming, saying he would refuse to voice Shaggy unless the character was vegetarian. An October 2019 South Park episode, "Let Them Eat Goo", featured a vegetarian character. Additionally, Steven Universe, the protagonist in the show Steven Universe and the limited epilogue series, Steven Universe Future, is a vegetarian. In the episode "Snow Day" of Steven Universe Future, Steven tells the Gems he lives with that he has been a vegetarian for a month, drinks protein shakes and mentions that he does "his own skincare routine."

SR9009 is a synthetic research compound that activates the REV-ERBα and REV-ERBβ nuclear receptors. It is not an approved drug and has no established human therapeutic use. Most published biological data come from cell and rodent studies.
No. SR9009 is frequently mislabeled as a SARM in online discussions, but it does not target androgen receptors. Its known mechanism involves REV-ERB nuclear receptors and circadian-metabolic gene regulation.
Human clinical data are very limited. There is no approved human use, and safety and efficacy in people are not established. Most evidence comes from preclinical models, so effects observed in animals may not apply to humans.
Research-grade SR9009 is typically stored frozen at about minus twenty degrees Celsius, protected from light and moisture. Stock solutions are often kept in aliquots to avoid repeated freeze-thaw cycles. Specific storage conditions should follow the supplier's documentation.
