A practical reference on REV-ERB agonist: what it is, how it behaves, what the literature reports, and where the honest uncertainties sit.
Reviewed 2026-06-01. Anything still debated is marked as such rather than presented as settled.
Because REV-ERB receptors are core clock components, SR9009 has been examined for effects on daily rhythms as well as metabolism. Research has explored whether the compound can shift or reinforce circadian gene expression in tissues such as liver and muscle. Some studies report improved metabolic markers in obese or diabetic mice, while others show context-dependent responses. Questions remain about which effects are direct, which are secondary to timing, and how they might differ across species.
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.
Detection of SR9009 in biological samples usually employs liquid chromatography coupled with tandem mass spectrometry. This method can identify the parent compound and sometimes metabolites in urine or blood. Because exposure can be low and clearance may be rapid, sample timing and limits of detection matter. Laboratories validate assays for sensitivity and specificity. Results are interpreted alongside chain-of-custody and quality-control records. Urine is the common matrix for anti-doping analysis, while blood may be used in research settings.
Handling recommendations for SR9009 in a laboratory setting include storing the solid at low temperature, protected from light and moisture. The compound is often dissolved in dimethyl sulfoxide or ethanol for experiments. Solutions should be prepared with appropriate personal protective equipment and disposed of according to local rules. Stability data for long-term storage are limited, so stock solutions are typically kept cold and used within defined periods. Records of preparation date and concentration support reproducibility.
SR9009 is not approved as a medicine by major regulatory agencies. It is commonly sold as a research chemical, a category that may fall outside customary drug approval and quality rules. In sports, the World Anti-Doping Agency lists SR9009 as a prohibited substance. Athletes who use it can face sanctions if it is detected in a sample. Legal status varies by country, and importation may be restricted. Enforcement practices differ across borders.

SR9009 is often grouped with compounds studied for circadian and metabolic regulation rather than with classical anabolic steroids. Its interactions with nuclear receptors differ from those of androgen receptor ligands, and its proposed mechanisms involve transcriptional control rather than direct hormone signaling. Some sources classify it as a metabolic modulator because of observed effects on energy utilization. The distinction matters for regulation and for interpreting research results across different compound classes.
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.
== Biodistribution and mechanisms of action == Lithium compartmentalization was studied in 11 biosubstrates of rats when lithium ascorbate was taken at a dose of 1000 mg/kg. As part of a tubeless analysis of the dynamics of concentrations in whole blood, the following values of the pharmacokinetic parameters of lithium ascorbate were obtained: Cmax=50.59 µg/l, tmax=1.50 h, Clast=33.7 µg/l, AUCt=1750 µg/l*h, MRTt=22.9 h, Lz=0.005 1/h, T1/2=141 h, CL=0.029 l/h, Vd=5.9 l. Multichamber pharmacokinetic analysis showed that the stabilization of lithium levels in the blood is maintained by a special "depot" of lithium, apparently consisting of the aorta, femur and brain. Application of the method of functional linkage analysis suggested that the targeted accumulation of ascorbate anion in cells is due to the activity of vitamin C transport proteins SLC23A1, SLC23A2, SLC23A3. At the same time, lithium ions and ascorbate exhibit a synergistic effect. The main effects of lithium include the support of normal excitability central nervous system: by preventing excessive concentration of norepinephrine, regulation of sodium concentration in muscle cells (which is important for the tone of blood vessels), sensitivity of neurons to dopamine, which reduces the negative impact of stress.
=== Recreational === Amphetamine, specifically the more dopaminergic dextrorotatory enantiomer (dextroamphetamine), is also used recreationally as a euphoriant and aphrodisiac, and like other amphetamines, is used as a club drug for its energetic and euphoric high. Dextroamphetamine (d-amphetamine) is considered to have a high potential for misuse in a recreational manner since individuals typically report feeling euphoric, more alert, and more energetic after taking the drug. A notable part of the 1960s mod subculture in the UK was recreational amphetamine use, which was used to fuel all-night dances at clubs like Manchester's Twisted Wheel. Newspaper reports described dancers emerging from clubs at 5 a.m. with dilated pupils. Mods used the drug for stimulation and alertness, which they viewed as different from the intoxication caused by alcohol and other drugs. Dr. Andrew Wilson argues that for a significant minority, "amphetamines symbolised the smart, on-the-ball, cool image" and that they sought "stimulation not intoxication [...] greater awareness, not escape" and "confidence and articulacy" rather than the "drunken rowdiness of previous generations." Dextroamphetamine's dopaminergic (rewarding) properties affect the mesocorticolimbic circuit; a group of neural structures responsible for incentive salience (i.e., "wanting"; desire or craving for a reward and motivation), positive reinforcement and positively-valenced emotions, particularly ones involving pleasure. Large recreational doses of dextroamphetamine may produce symptoms of dextroamphetamine overdose.
Quantum chemistry can also provide insight into the mechanism of an organic transformation without the collection of any experimental data. Because wavefunctions provide the total energy of a given molecular state, guessed molecular geometries can be optimized to give relaxed molecular structures very similar to those found through experimental methods. Reaction coordinates can then be simulated, and transition state structures solved. Solving a complete energy surface for a given reaction is therefore possible, and such calculations have been applied to many problems in organic chemistry where kinetic data is unavailable or difficult to acquire.

It is very easy for the Moroccan mafia to infiltrate Belgian politics. They do more damage than the drugs itself. I think it is unfair for leaders of political parties to see their party collapse. I already prefer to warn them that my political party will not be a potential collaborator. These organisations are content with an incredible turnover that can make them amongst the richest in Morocco. This week we have created the Kali-team. A team that is made up of 40 investigators to combat the Moroccan mafia in the Port of Antwerp.
Label-free quantification is a method in mass spectrometry that aims to determine the relative amount of proteins in two or more biological samples. Unlike other methods for protein quantification, label-free quantification does not use a stable isotope containing compound to chemically bind to and thus label the protein.
While exiting totally from Sabah and Sarawak. There had about 16 stores in both of the states which they transferred the business to local stores as new owners rather than closing them permanently. In 2020, Many branches would be replaced by TF Value-Mart or NSK Trade City. Similar downsize also observed in Singapore with the closure of two stores located at Bukit Panjang and Jalan Tenteram in Whampoa estate, and its VivoCity hypermarket in 2019. It also closed its Parkway Parade hypermarket on 29 February 2020. In May 2021, Giant announced its withdrawal from Indonesia since 31 July 2021. Some branches would be replaced with Hero Supermarket and IKEA small stores. Hero is previously owned by the DFI Retail Group, as it was spun off in 2024.
A substance is anhydrous if it contains no water. Many processes in chemistry can be impeded by the presence of water; therefore, it is important that water-free reagents and techniques are used. In practice, however, it is very difficult to achieve perfect dryness; anhydrous compounds gradually absorb water from the atmosphere so they must be stored carefully. Substances that contain water or its constituent elements are called hydrates.

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.
It binds REV-ERB alpha and REV-ERB beta and changes the expression of genes tied to metabolism and circadian rhythm. These changes can affect mitochondria and energy use in animal models. The exact chain from receptor binding to physiological outcome is still being mapped.
No reliable human trials show that SR9009 improves athletic performance. Some rodent studies report endurance changes, but these results are not proof of human benefit. Its use in sport is prohibited, and quality and safety data are lacking.
Its legal status depends on the country and intended use. It is not an approved medicine in major jurisdictions. In sport, it is prohibited by anti-doping rules.
