REV-ERB agonist comes up often in conversation and rarely with the context attached. Here we lay out the basics in order, then work through the practical considerations.
Last reviewed on 2025-08-15. Where a claim depends on a specific study, the study is described rather than over-claimed.
Analytical identification and purity assessment often use high-performance liquid chromatography with ultraviolet detection or mass spectrometry. Liquid chromatography–tandem mass spectrometry is used to detect and quantify SR9009 in biological matrices, including urine and blood, for anti-doping or pharmacokinetic studies. Nuclear magnetic resonance spectroscopy can confirm molecular structure. Stability depends on form and storage: the solid is generally more stable than solutions, and repeated freeze–thaw cycles may degrade samples. Purity is typically reported as a percentage from a certificate of analysis.
Regulatory treatment of SR9009 varies by country and context. It is not approved as a therapeutic drug by agencies such as the United States Food and Drug Administration or the European Medicines Agency. Sports authorities list it as a prohibited substance; the World Anti-Doping Agency classifies it among hormone and metabolic modulators. Legal status for personal possession or sale differs across jurisdictions, and some countries may restrict it under analog or research chemical laws. Buyers who seek verified material often rely on independent laboratory testing because online product labels may not match contents.
Laboratory samples of SR9009 are typically handled as research chemicals rather than pharmaceuticals. Suppliers usually state that the material is for research use only and not for human or veterinary administration. Storage recommendations generally call for a freezer at approximately −20 °C, protection from light, and a desiccated environment. The solid is often described as a white to off-white powder. Solubility is commonly reported in organic solvents such as dimethyl sulfoxide and ethanol, with low solubility in water.
SR9009 is a synthetic small molecule developed as a REV-ERB agonist. It binds to REV-ERBα and REV-ERBβ, nuclear receptors that help regulate circadian rhythms and metabolic gene expression. In cell and animal studies, the compound alters lipid and glucose handling and influences skeletal muscle oxidative capacity. Its exact effects in humans remain largely uncharacterized because controlled clinical trials have not been reported. The molecule is frequently described in preclinical literature as a metabolic modulator.
Research interest in SR9009 grew from studies showing improved running endurance in mice after short treatment periods. Those experiments linked the compound to increased mitochondrial content and fatty acid oxidation in muscle, but the findings come from animal models and specific dosing schedules. Independent replication has been limited, and the pathways connecting REV-ERB activation to exercise performance are still being mapped. Whether similar responses occur in humans is an open question.

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.
SR9009 is a synthetic small molecule studied as an agonist of the nuclear receptors REV-ERBα and REV-ERBβ. It is not an approved medicine and has no established human therapeutic use. The compound appears in scientific literature as a tool for probing circadian and metabolic regulation. Online sellers often label it as a research chemical, sometimes using the nickname Stenabolic. Its chemical identity is distinct from selective androgen receptor modulators, stimulants, and peroxisome proliferator-activated receptor delta agonists. Researchers use it mainly in cell and animal experiments.
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 supplied as a solid research chemical, often in milligram quantities. Laboratories typically weigh it in a controlled environment because fine powders can disperse. Stock solutions are commonly prepared in dimethyl sulfoxide and stored in small aliquots to reduce freeze-thaw cycles. Personal protective equipment and chemical fume hoods are standard when handling unknown or potent compounds. These practices address laboratory safety rather than human use.
Identity and purity of SR9009 samples are usually checked with chromatographic and spectrometric methods. High-performance liquid chromatography can separate the compound from related impurities, while mass spectrometry provides molecular mass confirmation. Nuclear magnetic resonance spectroscopy may be used for structural verification in research settings. No single method proves biological activity, and certificates of analysis should be reviewed alongside raw data. Independent testing is often needed because online products vary widely.
SR9009 stability depends on temperature, moisture, light, and solvent. Solid material is generally kept cool and dry, while solutions may require protection from repeated warming and cooling. Degradation can appear as color changes, precipitate, or new chromatographic peaks. Researchers should follow supplier instructions and their own stability data. Long-term storage conditions for human use have not been established because the compound lacks approved clinical formulation.
Handling practices for SR9009 focus on minimizing degradation and contamination. The solid is generally stored desiccated at or below -20 °C, protected from light and moisture. Stock solutions are often prepared in dimethyl sulfoxide or ethanol, then aliquoted to avoid repeated freeze–thaw cycles. Aqueous solubility is low, so formulations for animal studies may require cosolvents or suspending agents. Personnel should follow institutional chemical safety procedures, because toxicological data for humans are incomplete.
Regulatory status varies by country and intended use. Major drug agencies have not granted marketing authorization for SR9009 as a medicine, and it is not listed as a controlled substance in many jurisdictions. It is often sold as a research chemical, a category that may fall outside pharmaceutical manufacturing rules. Buyers should verify local laws and supplier documentation, including certificates of analysis. The lack of standardized quality controls raises concerns about identity, purity, and actual content in products marketed online.
Hence, although DOM-NBOMe could still be an active psychedelic in humans, it may have attenuated hallucinogenic effects compared to non-25-NB DOx psychedelics. The doses of DOM-NBOMe producing the head-twitch response were not reported.

==== Prontosan ==== Prontosan (B Braun) Wound Irrigation Solution and Prontosan Wound Gel are proprietary preparations of PHMB with betaine, an alkaloid surfactant. Surfactants lower the surface tension of the fluid medium making it easier to infiltrate wound coatings, debris and bacteria. Both the wound irrigation solution and the wound gel are colorless cleansing agents that are indicated for use in acute and chronic wounds. They also have the potential to be used in conjunction with a range of dressing materials which include occlusive dressings. In vitro studies on clinical isolates of E. coli and S. epidermidis have demonstrated the anti-biofilm efficacy of PHMB. The activity of five biocides at various concentrations was recorded following exposure to the isolates. The biocides found to be most active towards planktonic (free floating) cells were PHMB and peracetic acid. A corresponding level of activity towards biofilm phenotype bacteria was also found with the two agents. Prontosan's activity on MRSA biofilms has been investigated using an in vivo porcine wound model. Prontosan activity was compared with Ringer's solution, saline, and untreated control. A comparative reduction in MRSA at 48 and 72 hours in the Prontosan-treated group was found to be statistically significant compared to the other groups (p-value <0.05). The study results indicated that extended irrigation with Prontosan may provide additional reduction in wound bioburden as the largest reduction of MRSA was found from 48 to 72 hours.

The Maya civilization emerged at least three millennia ago in the lowland area of the Yucatán Peninsula and the highlands to the south, in the area of present-day southeastern Mexico, Belize, Guatemala, and western Honduras. Many aspects of this culture persist in the area, despite nearly 500 years of European domination. Before about 2500 BC, some hunting and foraging bands settled in small farming villages; they domesticated crops such as corn, beans, squash, and chilli peppers. A profusion of languages and subcultures developed within the Maya core culture. Between about 2500 BCE and 250 AD, the basic institutions of Maya civilization emerged.

== Early life and biography == Kearon was born on 18 July 1961 in Carlisle, England. He spent part of his youth in Saudi Arabia, where his father worked. After his father's death when Kearon was 19, he gave up on additional formal education and entered the workforce. His first job was working for a Member of Parliament, and he later worked for Nestlé in England, Saudi Arabia, and the United States. He owned his own public affairs consulting company before beginning his full-time service in the church. Kearon was first introduced to the church in the mid-1980s while staying with a Latter-day Saint family in Laguna, California. He has said that the family "lived a joyful existence founded on service." He met missionaries in London several years later and began learning about the church, and was baptized on Christmas Eve, 1987.
In humans, glucose is metabolized by glycolysis and the pentose phosphate pathway. Glycolysis is used by all living organisms, with small variations, and all organisms generate energy from the breakdown of monosaccharides. In the further course of the metabolism, it can be completely degraded via oxidative decarboxylation, the citric acid cycle (synonym Krebs cycle) and the respiratory chain to water and carbon dioxide. If there is not enough oxygen available for this, the glucose degradation in animals occurs anaerobic to lactate via lactic acid fermentation and releases much less energy. Muscular lactate enters the liver through the bloodstream in mammals, where gluconeogenesis occurs (Cori cycle). With a high supply of glucose, the metabolite acetyl-CoA from the Krebs cycle can also be used for fatty acid synthesis. Glucose is also used to replenish the body's glycogen stores, which are mainly found in liver and skeletal muscle. These processes are hormonally regulated. In other living organisms, other forms of fermentation can occur. The bacterium Escherichia coli can grow on nutrient media containing glucose as the sole carbon source. In some bacteria and, in modified form, also in archaea, glucose is degraded via the Entner-Doudoroff pathway. With glucose, a mechanism for gene regulation was discovered in E. coli, the catabolite repression (formerly known as glucose effect). Use of glucose as an energy source in cells is by either aerobic respiration, anaerobic respiration, or fermentation.
== History == Vitacost began operations in 1994 as a catalog retailer of third-party vitamins and supplements under the name Nature's Wealth Company by its founder Wayne Gorsek. In 1999, the company launched Vitacost.com and introduced proprietary vitamins and supplements, which has since expanded to include food, beauty products and sports nutrition. The company completed construction of a manufacturing facility located in Lexington, North Carolina, in 2008. Effective September 1, 2012, Vitacost agreed to lease its manufacturing facilities to a third-party provider. On September 23, 2009, Vitacost went public. Vitacost shares traded on the NASDAQ were suspended on December 7, 2010, for financials not adding up. By the time the stock was reinstated by NASDAQ, the stock had lost most of its value with investors losing almost all of their investment. ("Gebben"). During 2010, the company expanded and upgraded its West Coast distribution facility located in Las Vegas, Nevada. The Company began a similar project for its east coast distribution center, located in Lexington, North Carolina in the spring of 2010, with the building construction completed in the first quarter of 2011. Gorsek was found guilty of securities fraud on January 28, 2003. The SEC Commission announced on this day that the Honorable Jeanne E. Scott, U.S. District Judge for the Central District of Illinois, has found two former brokers and stock promoters, Wayne F. Gorsek ("Gorsek") and Lyndell F.
