In rodent studies, SR9009 has been reported to increase mitochondrial content in skeletal muscle and improve exercise endurance under some conditions. These findings led to popular descriptions such as an exercise mimetic, although that term oversimplifies the biology. Effects vary by dose, timing, tissue, and model. The compound's influence on circadian pathways means that time of administration can matter in experiments. Whether similar metabolic changes occur in humans remains largely unexplored in controlled published trials.
Pharmacokinetic data for SR9009 are limited in published literature. Some reports indicate low oral bioavailability and rapid clearance in animals, which complicates interpretation of exposure and effect. Researchers often use injected routes in preclinical work to achieve measurable systemic levels. Analytical studies rely on mass spectrometry to detect the parent compound and its metabolites. Questions about tissue distribution, active metabolites, and long-term consequences remain open. Species differences in metabolism can affect observed half-life and target engagement.
Most published work on SR9009 consists of preclinical studies. It is widely sold as a research chemical, a category that does not imply safety, efficacy, or pharmaceutical-grade quality. Sports anti-doping organizations have listed SR9009 as a prohibited substance, and its presence in an athlete sample can lead to sanctions. Legal status differs by country; in several jurisdictions it is not approved for human consumption and may be treated as an unapproved new drug.
SR9009 is a synthetic small molecule studied as an agonist of the nuclear receptors REV-ERBα and REV-ERBβ. It is not a steroid, peptide, or natural hormone. In scientific literature, it appears under the code SR9009 and in non-scientific contexts as Stenabolic. The compound was identified through chemical screening efforts aimed at targeting circadian clock components. Its status remains investigational, and no regulatory agency has approved it as a human medicine.
REV-ERB proteins help regulate daily cycles in gene expression, including genes tied to lipid and glucose metabolism. SR9009 binds these receptors and alters their activity in cell and animal experiments. Consequences observed in rodents include changes in skeletal muscle oxidative capacity, blood lipid levels, and exercise performance. The precise chain from receptor occupancy to whole-body effects is still an active area of study. Human responses cannot be assumed from rodent data.
| Property | Value | Notes |
|---|---|---|
| Chemical class | Synthetic small-molecule REV-ERB agonist | Not a hormone or natural product |
| Primary targets | REV-ERBα and REV-ERBβ | Nuclear receptors involved in circadian and metabolic regulation |
| Appearance | White to off-white solid | Typical for purified research samples |
| Solubility | Soluble in DMSO and ethanol; low water solubility | Laboratory solubility depends on solvent and purity |
| Common synonyms | SR9009; Stenabolic | Stenabolic is a colloquial name, not a formal chemical name |
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.
Detection in biological samples can be complicated by rapid metabolism and low circulating concentrations. Some studies report phase I and phase II metabolites, and analytical methods may need to target those species in addition to the parent compound. Immunoassays are not broadly available, so mass spectrometry remains the main confirmatory approach. For anti-doping testing, laboratories look for SR9009 and its metabolites using validated LC-MS methods. Open questions include how long metabolites remain detectable and how different routes of administration alter detection windows.
In laboratory settings, SR9009 is typically characterized by liquid chromatography–mass spectrometry (LC-MS) or high-performance liquid chromatography with ultraviolet detection (HPLC-UV). These methods can confirm identity and estimate purity, but they require reference standards for accurate quantification. Because SR9009 is not a licensed pharmaceutical, no harmonized pharmacopeial monograph exists. Laboratories often validate in-house methods for matrices such as plasma, urine, or cell culture media. Sample preparation may involve protein precipitation or liquid-liquid extraction before analysis.

=== Murder conviction === Cochran was later convicted of first-degree murder in state court for poisoning her husband, Michael Brandon Cochran, with insulin. Prosecutors argued that Michael had grown suspicious of their business dealings and planned to investigate further. On February 5, 2019, Cochran canceled Michael’s flight to Virginia, where he intended to investigate their business dealings, and injected him with insulin. Despite his deteriorating condition, Cochran refused to take him to the hospital, telling friends he would “sleep it off.” Michael died on February 11, 2019. During the trial, forensic experts confirmed that Michael’s death was caused by nonprescribed insulin. Prosecutors argued that Cochran killed her husband to prevent him from uncovering her fraudulent activities. The jury deliberated for less than two hours before delivering a guilty verdict. In January 2025, Cochran was sentenced to life imprisonment without parole, with the jury recommending no mercy. After announcing in November 2023 that he would not run for re-election at the end of 2024, Judge H.L. Kirkpatrick, stated that he would preside over the Natalie Cochran trial by special appointment.
=== In popular culture === Mikhail Sholokhov's monumental work, "And Quiet Flows the Don", deals sympathetically with the Don Cossacks and depicts the destruction of their way of life as a result of World War I and the Russian Civil War.
== Mechanism of action == Canfosfamide is specifically activated in the presence of elevated GST P1-1, which is commonly found in various cancer types. Upon activation, it is converted into an alkylating agent that induces DNA damage, leading to apoptosis in cancer cells.
=== Industrial scale === In a similar fashion to some laboratory methods, acetamide is produced by dehydrating ammonium acetate or via the hydration of acetonitrile, a byproduct of the production of acrylonitrile:

Like Canada hemlock, this tree suffers severely from the hemlock woolly adelgid. Several species of pines characteristic of the Appalachians are eastern white pine (Pinus strobus ), Virginia pine (Pinus virginiana), pitch pine (Pinus rigida ), Table Mountain pine (Pinus pungens) and shortleaf pine (Pinus echinata). Red pine (Pinus resinosa) is a boreal species that forms a few high elevation outliers as far south as West Virginia. All of these species except white pine tend to occupy sandy, rocky, poor soil sites, which are mostly acidic in character. White pine, a large species valued for its timber, tends to do best in rich, moist soil, either acidic or alkaline in character. Pitch pine is also at home in acidic, boggy soil, and Table Mountain pine may occasionally be found in this habitat as well. Shortleaf pine is generally found in warmer habitats and at lower elevations than the other species. All the species listed do best in open or lightly shaded habitats, although white pine also thrives in shady coves, valleys, and on floodplains. The Appalachians are characterized by a wealth of large, beautiful deciduous broadleaf (hardwood) trees. Their occurrences are best summarized and described in E. Lucy Braun's 1950 classic, Deciduous Forests of Eastern North America (Macmillan, New York).

Ellen Jane Langer (; born March 25, 1947) is an American psychologist and professor of psychology at Harvard University. In 1981, she became the first woman to be tenured in psychology at Harvard. She has been called the "mother of mindfulness" and the "mother of positive psychology". Langer studies the illusion of control, decision-making, aging, and mindfulness theory. Her most influential work is Counterclockwise, published in 2009, the first test of her mind/body unity theory. Her most recent book, The Mindful Body: Thinking Our Way to Chronic Health, published in 2023, argues for the enormous control we have over our health based on mind/body unity.
While uterine prolapse is rarely life-threatening, the symptoms associated with uterine prolapse can have a significant impact on quality of life. The severity of prolapse symptoms does not necessarily correlate with the degree of prolapse, and one may experience little to no bothersome symptoms with even advanced prolapse. Additionally, different forms of pelvic organ prolapse often present with similar symptoms. Most women who experience pelvic organ prolapse do not have symptoms. When symptoms are present, the most common and most specific symptoms for uterine prolapse—and organ prolapse in general—into the vagina are bulge symptoms, such as pelvic pressure, vaginal fullness, or a palpable vaginal bulge, and these symptoms are often more common and more severe if the prolapse reaches the vaginal hymen. Urinary symptoms, such as uncontrollable loss of urine or difficulty urinating, may also be present. Complete uterine prolapse in which the uterus protrudes through the vaginal hymen is known as procidentia. In the absence of treatment, symptoms of procidentia may include purulent vaginal discharge, ulceration, and bleeding. Complications of procidentia include urinary obstruction. People may also report sexual dysfunction symptoms, such as pain with sexual intercourse and decreased libido. There is conflicting data concerning the effect of pelvic organ prolapse on sexual function. The severity of the symptoms associated with prolapse seems to have a negative effect on sexual activity and reported satisfaction.
