If you have been reading about Research chemical and want a single page that covers the useful parts, this is it: definitions, context, how it is studied, and the questions that come up repeatedly.
Last reviewed on 2026-07-11. Where a claim depends on a specific study, the study is described rather than over-claimed.
Regulatory treatment of cardarine differs by context and jurisdiction. In competitive sport, the World Anti-Doping Agency lists PPARδ agonists, including GW501516, as prohibited at all times. Outside sport, it lacks approval as a prescription medicine in major drug markets, and products sold for human consumption may be treated as unapproved drugs. Some countries also restrict importation or sale through general consumer protection and medicines laws. These classifications affect availability, testing, and legal risk without establishing therapeutic value.
Because cardarine is not an approved medicine, no pharmacopeial monograph defines its identity, purity, or storage requirements. Laboratories typically rely on in-house methods and reference standards when testing materials labeled as GW501516. Certificates of analysis may report purity and identity for a specific batch, but their scope varies and they do not guarantee safety or legal status. Independent verification can include high-performance liquid chromatography, mass spectrometry, nuclear magnetic resonance, and elemental analysis. The distinction between research chemical labeling and human use is significant because quality standards and oversight differ.
A common misconception is that cardarine has been proven safe for human use. In reality, human clinical data are limited, and long-term animal studies have raised concerns about cancer. Another misconception is that it is a supplement or vitamin-like compound. It is a synthetic research chemical with no approved medical indication. Scientific discussion often focuses on its mechanism and detection rather than therapeutic use. Regulatory and anti-doping literature treats it primarily as a prohibited substance.
Cardarine is explicitly prohibited by the World Anti-Doping Agency under the class of PPARδ agonists. Its presence in urine or blood samples can be detected using mass spectrometry-based methods, often liquid chromatography-tandem mass spectrometry. Athletes who test positive may face sanctions, including bans from competition. The compound is also regulated as a prescription-only or unapproved drug in many countries. Enforcement varies by jurisdiction, and some regions treat it as a controlled substance. Online sales may occur despite these restrictions, creating quality and legal risks.

After the Rollercoaster Tour to support the album, the band concentrated on cracking the United States' market, with an appearance on David Letterman's show, and a tour as part of the Lollapalooza line-up, which William later described as "the worst experience of our lives," followed by their own headlining tour. In December 1992, the Reids again lost their rhythm section, with Ben Lurie returning and Steve Monti joining on drums. Another compilation was released in 1993, The Sound of Speed, before they returned to the studio to record their fifth album proper, Stoned & Dethroned which would see release in 1994, and featured guest appearances from Shane MacGowan and William's then-girlfriend Hope Sandoval. The album was originally planned as an acoustic album, but this idea was abandoned because, in Jim's words, "We couldn't do enough interesting things with acoustic guitars to make an album". In the 1995 EP released under American Records, a number of new works and B-sides were published which were later collected in the album Munki. After the release of the 1995 compilation Hate Rock 'N' Roll, the Mary Chain parted ways with Blanco y Negro, their record label of over a decade, and re-signed to their original label Creation Records, and Sub Pop in America. The band now included former Lush bassist Phil King. They then recorded 1998's Munki album, which would turn out to be their last before splitting the following year. Munki was commercially the least successful album the band released, peaking at number forty-seven in the UK Album Chart.
== Overview == The first observation of cellular structures resulting from the freezing of water goes back over a century, but the first reported instance of freeze-casting, in the modern sense, was in 1954 when Maxwell et al. attempted to fabricate turbosupercharger blades out of refractory powders. They froze extremely thick slips of titanium carbide, producing near-net-shape castings that were easy to sinter and machine. The goal of this work, however, was to make dense ceramics. It was not until 2001, when Fukasawa et al. created directionally porous alumina castings, that the idea of using freeze-casting as a means of creating novel porous structures really took hold. Since that time, research has grown considerably with hundreds of papers coming out within the last decade. The principles of freeze casting are applicable to a broad range of combinations of particles and suspension media. Water is by far the most commonly used suspension media, and by freeze drying is readily conducive to the step of sublimation that is necessary for the success of freeze-casting processes. Due to the high level of control and broad range of possible porous microstructures that freeze-casting can produce, the technique has been adopted in disparate fields such as tissue scaffolds, photonics, metal-matrix composites, dentistry, materials science, and even food science. There are three possible end results to uni-directionally freezing a suspension of particles. First, the ice-growth proceeds as a planar front, pushing particles in front like a bulldozer pushes a pile of rocks.
=== Extraction thimbles === Extraction thimbles are rod-shape filter paper often used in soxhlet extractors or atomized extractors. It is ideal for very sensitive detection, the performance depends on the thickness of inner diameter. Also, it is usually used in areas of food control and environmental monitoring.
=== Use as a fat loss supplement === 3,5-Diiodo-L-thyronine and 3,3′-diiodo-L-thyronine are used as ingredients in certain over-the-counter fat-loss supplements, designed for bodybuilding. Several studies have shown that these compounds increase the metabolization of fatty acids and the burning of adipose fat tissue in rats.

=== Greenlandic === The longest word in Greenlandic is Nalunaarasuartaateeraaranngualioqatigiiffissualioriataallaqqissupilorujussuanngortartuinnakasinngortinniamisaalinnguatsiaraluallaqqooqigaminngamiaasiinngooq, which has 156 letters. The rough translation of this word is: "There were reports that they apparently – God knows for how many times – once again had considered whatever I, my poor condition despite, still could be considered to be quite adept and resourceful as initiator to put a consortium together for the establishment of a range of tiny radio stations." The word is a tongue twister that forms an entire sentence, rather than being a word or phrase commonly heard in Greenland. Inuussutissarsiorsinnaajunnaarnersiutilik, consisting of 41 letters, is the longest singular word in the Greenlandic dictionary.
Industrial equipment. Fish and poultry processing machinery from Baader, Lübeck, bottle washers and pasteurizers from Krones, Flensburg, grinding machine tools from Peter Wolters, Rendsburg, machinery to manufacture human-made fibers, and non-woven textile from Oerlikon Neumag and Oerlikon Nonwoven, Neumünster. Medical and labor equipment. Drägerwerk in Lübeck manufactures breathing equipment, medical ventilators and monitors, anesthetic machines, neonatal incubators, gas detectors, drug testing equipment, diving equipment, rebreathers, and breathalyzers. The company delivers breathing devices for reanimation COVID-19 patients. Euroimmun, Lübeck, produces test systems with which antibodies can be determined in the serum of patients and thus autoimmune and infectious diseases (including COVID-19) as well as allergies. Chemical. Almost all chemical industry is concentrated around Brunsbüttel. Covestro, with 650 employees, produced annually 400,000 tonnes methylene diphenyl diisocyanate, which using in synthesis of polyurethane. Yara (214 employees) produces nitrogen fertilizers, but, with a special process, instead of using natural gas, it uses heavy oil, which also allows the manufacture of byproduct vanadium oxide and sulphur. Heavy oil is a source material to produce bitumen by Total Bitumen (130 empl.). Other plant is Sasol (520 empl.), which produce fatty and Guerbet alcohols, paraffin and high-purity aluminium oxide, aluminium hydroxide and triethylaluminium.
The precursor to indigo is indican, a colorless, water-soluble derivative of the amino acid tryptophan, and Indigofera leaves contain as much as 0.2–0.8% of this compound. Pressing cut leaves into a vat and soaking hydrolyzes the indican, releasing β-D-glucose and indoxyl. The indoxyl dimerizes in the mixture, and after 12–15 hours of fermentation yields the yellow, water-soluble leucoindigo. Subsequent exposure to air forms the blue, water-insoluble indigo dye. The dye precipitates from the fermented leaf solution upon oxidation, but may also be precipitated when mixed with a strong base such as lye. The solids are filtered, pressed into cakes, dried, and powdered. The powder is then mixed with various other substances to produce different shades of blue and purple. Natural sources of indigo also include mollusks: the Murex genus of sea snails produces a mixture of indigo and 6,6'-dibromoindigo (red), which together produce a range of purple hues known as Tyrian purple. Light exposure during part of the dyeing process can convert the dibromoindigo into indigo, resulting in blue hues known as royal blue, hyacinth purple, or tekhelet.
Because trans fats are more linear, they crystallize more easily, allowing them to be solid (rather than liquid) at room temperatures. This has several processing and storage advantages. In nature, unsaturated fatty acids generally have cis configurations as opposed to trans configurations. Saturated fatty acids (those without any carbon-carbon double bonds) are abundant (see tallow), but they also can be generated from unsaturated fats by the process of fat hydrogenation. In the course of hydrogenation, some cis double bonds convert into trans double bonds. Chemists call this conversion an isomerization reaction. Any molecule with a C=C double bond can be either a trans or a cis fatty acid depending on the configuration of the double bond. For example, oleic acid and elaidic acid are both unsaturated fatty acids with the chemical formula C9H17C9H17O2. They both have a double bond located midway along the carbon chain. It is the geometry of this bond that sets oleic and elaidic acids apart. They have distinct physical-chemical properties of the molecule. For example, the melting point of elaidic acid is 45 °C, which is higher than that of oleic acid. This notably means that it is a solid at human body temperatures.
=== 15 November === The SAF retook Um Dam Haj Ahmed and Kazgeil in North Kordofan from the RSF. One person was killed in a suspected RSF drone attack on the Bashayer oil processing station in Al Jabalayn, White Nile State.
