Everything below concerns GW501516. We keep the language plain, cite what the science says, and separate well-supported claims from open questions.
Last reviewed on 2026-08-01. Where a claim depends on a specific study, the study is described rather than over-claimed.
Cardarine is a synthetic compound also known as GW501516, GW-501516, and sometimes endurobol. It was developed as a selective agonist of peroxisome proliferator-activated receptor delta, a nuclear receptor involved in fatty acid oxidation and energy metabolism. The compound was studied in preclinical models for metabolic and cardiovascular conditions, but it did not become a marketed human medicine. In regulatory and anti-doping contexts, it is treated as a prohibited substance rather than a licensed medicine.
The pharmacological interest in cardarine centers on PPARδ activation and its downstream effects on lipid handling and mitochondrial function. In animal studies, PPARδ agonists have been associated with changes in exercise endurance and fatty acid utilization, though results vary by model and protocol. Human data remain sparse, and the absence of large controlled trials limits conclusions about efficacy. Researchers often describe the compound as a tool for probing PPARδ biology rather than a proven therapeutic agent.
Anti-doping laboratories identify GW501516 and related metabolites using liquid chromatography coupled with tandem mass spectrometry. Urine is the most common matrix, though blood and dried blood spots may also be analyzed. The method targets the parent compound and phase I and phase II metabolites, which extend the detection window. Because the substance is prohibited at all times, athletes can be tested outside competition. Detection limits and windows depend on the assay, sample type, and individual metabolism.
Cardarine is frequently described as a fat-burning or endurance-enhancing supplement, but these claims exceed the available evidence. The compound is not a hormone, steroid, or selective androgen receptor modulator. Research articles discuss it as a tool compound for studying PPARδ biology, while anti-doping literature focuses on its abuse and detection. Quality of unapproved products is uncertain, and independent analyses have found impurities or incorrect labeling. Open questions include whether human cancer risk resembles that seen in rodents and how often non-athletes use the substance.
Cardarine has no approved therapeutic indication and is not marketed as a medicine. The World Anti-Doping Agency lists GW501516 as a prohibited substance at all times, covering both in-competition and out-of-competition periods. National laws vary: some countries treat it as an unapproved drug subject to import controls, while others have specific restrictions on sale for human consumption. It is often sold as a research chemical, a label that does not imply safety or legality. Enforcement actions have targeted online vendors and shipments.

Published studies have examined GW501516 in animal models of obesity, insulin resistance, and exercise endurance. Early human trials reportedly ended, and development was discontinued after preclinical findings raised concerns about cancer in some rodent studies. Regulatory agencies have not approved cardarine for any medical use. Its availability through non-pharmaceutical channels raises questions about identity, purity, and legal status that are separate from its laboratory pharmacology. Those questions are often addressed through analytical testing rather than assumptions about product labels.
Cardarine is a common name for GW501516, also GW-1516, a synthetic compound developed as a peroxisome proliferator-activated receptor delta (PPARδ) agonist. It belongs to a class of agents that modulate gene transcription related to lipid and energy metabolism. The compound was studied in preclinical and early clinical research for metabolic and cardiovascular conditions, but it did not progress to approved therapeutic use. Its name appears in fitness and sports contexts despite not being approved as a drug.
PPARδ is a nuclear receptor that influences transcription of genes involved in fatty acid oxidation, lipid transport, and energy homeostasis. GW501516 binds and activates this receptor with high selectivity relative to PPARα and PPARγ in laboratory assays. Activation alters expression of target genes in skeletal muscle, liver, and adipose tissue in animal models. The exact clinical consequences of these changes in humans remain incompletely characterized, and observed effects in animals do not establish therapeutic benefit or safety.
Products sold as cardarine have been found to contain incorrect compounds, variable amounts, or no active ingredient at all. Independent testing is required to verify identity and purity. Common analytical approaches include high-performance liquid chromatography, mass spectrometry, and nuclear magnetic resonance for structural confirmation. These methods can distinguish GW501516 from related PPAR agonists and from unrelated steroids. For regulators and researchers, such verification is central to interpreting both biological results and adverse event reports.
Cardarine is prohibited in competitive sport under the World Anti-Doping Agency code, where it is classified as a metabolic modulator. It is not approved as a prescription medicine in the United States, European Union, or other major markets. Regulatory action has focused on its presence in sports and in products marketed as research chemicals. Because it has no accepted medical indication, supply is often unregulated. This status creates legal and safety uncertainties for anyone who encounters the substance.
GW501516 acts on PPARδ, a nuclear receptor that helps regulate fatty acid oxidation and energy homeostasis. In animal studies, activation of this receptor was associated with increased endurance and changes in lipid metabolism. Human trials examined effects on blood lipids and other metabolic markers, but the compound did not advance to approval. Rodent studies later reported tumors in multiple tissues at doses used in those experiments. Whether those findings translate to human risk remains uncertain, and the clinical relevance of the animal data is still debated.
Regulatory bodies treat GW501516 as a prohibited substance in competitive sport. The World Anti-Doping Agency added it to the prohibited list, and it falls under classes covering metabolic modulators and hormone-related agents. It is not approved by drug regulators for human use, and it is not a lawful dietary supplement. Products sold under the cardarine name may contain unlisted ingredients or different compounds. Because no approved product exists, quality and identity are not guaranteed by pharmaceutical manufacturing standards.
Cardarine is a common name for the investigational chemical GW501516, also written GW-1516. It was developed as a peroxisome proliferator-activated receptor delta agonist for metabolic conditions such as dyslipidemia. Early research focused on lipid handling and energy use in skeletal muscle and other tissues. The compound was never approved as a medicine. In public discussion, it is often grouped with performance-enhancing substances, although its receptor target differs from that of anabolic steroids or selective androgen receptor modulators. Regulatory and health authorities have issued warnings about its use.
In 1811 François Arago constructed a polariscope and used it to discover that quartz crystals would rotate the plane of polarization of polarized light. Shortly after Jean-Baptiste Biot found a similar optical rotation effect for solutions, for example tartaric acid, and concluded that the effect was a inherent property of certain molecules. In 1830 Jöns Jacob Berzelius discovered that tartaric and racemic acids have the same elementary composition, and concluded that a difference in the arrangement of the atoms in the molecules creates compounds with different chemical properties; in the same paper Berzelius suggested the term "isomerism" for the phenomenon. In 1831 Mitscherlich was asked by Berzelius to study the tartrates in order to determine the differences between two isomers, tartaric acid and racemic acid. By 1832, Jean-Baptiste Biot had discovered that tartaric acid from grape juice was dextrorotatory and that racemic acid was optically inactive. In 1844 Mitscherlich found that the solution of sodium ammonium tartrate was optically active, but that of sodium ammonium paratartrate was optically inactive. The work of Biot and Mitscherlich was the starting point for research by the French chemist Louis Pasteur, a doctoral student of Gabriel Delafosse and a colleague of Auguste Laurent. In 1848 Louis Pasteur gave the general relation between crystal morphology and rotatory polarization.
=== 11 January === Russian Defence Minister Sergei Shoigu appointed Valery Gerasimov in place of Sergey Surovikin as overall commander of the war against Ukraine. Surovikin would serve as Gerasimov's deputy. The Wagner Group claimed around 500 Ukrainians were killed during the battle of Soledar.
=== Medical === Puffballs are a known styptic and have long been used as wound dressing, either in powdered form or as slices 3 cm thick. Authors Hui-Yeng Y. Yap, Mohammad Farhan Ariffeen Rosli, et al. found evidence to suggest that C. gigantea was "traditionally used by American Indians, Nigerian and German folks" for this purpose. The authors, however, did not specify the preferred form of wound dressing (e.g., powdered or sliced). In addition to consuming the mushroom, the Māori people of New Zealand used it to stem bleeding and treat burns.
=== Cancer === Sugar consumption does not directly cause cancer. Cancer Council Australia have stated that "there is no evidence that consuming sugar makes cancer cells grow faster or cause cancer". There is an indirect relationship between sugar consumption and obesity-related cancers through increased risk of excess body weight. The American Institute for Cancer Research and World Cancer Research Fund recommend that people should limit sugar consumption.

=== Economics === Copra production begins on coconut plantations. Coconut trees are generally spaced 9 m (30 ft) apart, allowing a density of 100–160 coconut trees per hectare. A standard tree bears around 50–80 nuts a year, and average earnings in Vanuatu (1999) were US$0.20 per kg (one kg equals 8 nuts)—so a farmer could earn approximately US$120 to US$320 yearly for each planted hectare. Copra has since more than doubled in price, and was quoted at US$540 per ton in the Philippines on a CIF Rotterdam basis (US$0.54 per kg) by the Financial Times on 9 November 2012. In 2017 the value of global exports of copra was $145-146 Million. The largest exporter was Papua New Guinea with 35% of the global total, followed by Indonesia (20%), Solomon Islands (13%) and Vanuatu (12%). The largest importer of copra is the Philippines, which imports $93.4 Million or 64% of the global total. A very large number of small farmers and tree owners produce copra, which is a vital part of their income.
=== Type 2 Diabetes === Failure in the regulation of glyceroneogenesis may lead to type 2 diabetes, a metabolic disorder that results in high levels of blood glucose and blood lipid. Type 2 diabetes, in addition to a decreased sensitivity to insulin, is associated with the overproduction of triglycerides in the liver, due to excessively active glyceroneogenesis and excess release of fatty acids from adipose tissues. Glyceroneogenesis can be regulated by controlling the gene expression of PEPC-K. Overexpressing PEPC-K in the liver will overproduce triglycerides and elevate the lipid level in the bloodstream, increasing the risk of fatty liver disease (hepatic steatosis). Conversely, in adipose tissue, down-regulated glyceroneogenesis may decrease de novo lipogenesis, increasing the export of free fatty acids to the bloodstream, leading to lipodystrophy. Both of these conditions are highly associated with type 2 diabetes.

In dental anatomy, the gingival fibers are the connective tissue fibers that inhabit the gingival tissue (gums) adjacent to teeth and help hold the tissue firmly against the teeth. They are primarily composed of type I collagen, although type III fibers are also involved. These fibers, unlike the fibers of the periodontal ligament, in general, attach the tooth to the gingival tissue, rather than the tooth to the alveolar bone.
In December 2024, research commissioned by the UK recycling charity Material Focus estimated that 13 vapes were being thrown away every second in the UK, amounting to over a million per day, and that approximately 8.2 million vapes a week were discarded or recycled incorrectly, with growth linked to larger "big puff" devices. Research led by University College London and the University of Oxford reported that lithium-ion cells inside some disposable vapes can retain high capacity after hundreds of charge-discharge cycles, underscoring resource waste and the importance of proper collection and recycling of embedded batteries. Recycling challenges, waste issues, and fire hazards are cited. Concerns about youth vaping are also raised. The UK Vaping Industry Association defends disposables as quitting aids and warns of potential black market products if banned. Although some brands have begun recycling services for their e-cigarette cartridges and batteries, the prevalence of recycling is unknown. A 2024 UK study reported that only a minority of surveyed retailers provided recycling points despite existing legal obligations, and estimated that more than 250 million disposable vapes could be discarded before regulatory restrictions came into force. Several jurisdictions subsequently moved to restrict or ban single-use (disposable) vapes while allowing reusable products, citing environmental and waste concerns. In Australia, imports of disposable vapes were prohibited from 1 January 2024 under new import controls.

The penis is soaked and par-boiled to remove any remaining urine, then boiled with vegetables for several hours. Lasopy soucril is served at a high temperature with pepper and chilies.
Social constructivists argue that technologies follow no natural progression, and they are shaped by cultural values, laws, politics, and economic incentives. Modern scholarship has shifted towards an analysis of sociotechnical systems, "assemblages of things, people, practices, and meanings", looking at the value judgments that shape technology. Cultural critic Neil Postman distinguished tool-using societies from technological societies and from what he called "technopolies", societies that are dominated by an ideology of technological and scientific progress to the detriment of other cultural practices, values, and world views. Herbert Marcuse and John Zerzan suggest that technological society will inevitably deprive humanity of its freedom and psychological health.
== Lithium-titanate battery == The lithium-titanate battery is a rechargeable battery that is much faster to charge than other lithium-ion batteries. It differs from other lithium-ion batteries because it uses lithium-titanate on the anode surface rather than carbon. This is advantageous because it does not create a solid electrolyte interface layer, which acts as a barrier to the ingress and egress of Li-ion to and from the anode. This allows lithium-titanate batteries to be recharged more quickly and provide higher currents when necessary. A disadvantage of the lithium-titanate battery is a much lower capacity and voltage than the conventional lithium-ion battery. The lithium-titanate battery is currently being used in battery electric vehicles and other specialist applications.
It is a tetracyclic compound, consisting of four rings in a three dimensional configuration, and is very closely related structurally to the tetracyclic antidepressant (TeCA) maprotiline, differing only in the length of their side chain.
