Everything below concerns Cardarine. We keep the language plain, cite what the science says, and separate well-supported claims from open questions.
Last reviewed on 2026-02-08. Where a claim depends on a specific study, the study is described rather than over-claimed.
Activation of PPARδ changes transcription of genes involved in fatty acid transport, mitochondrial function, and skeletal muscle fuel preference. In rodent studies, pharmacological PPARδ activation was associated with increased endurance and altered body composition. These findings generated interest in performance enhancement, but species differences and study designs limit direct extrapolation to humans. Small human trials were conducted in the 2000s and later discontinued. The extent to which cardarine produces similar metabolic or performance effects in people remains an open question.
The compound is typically described as a laboratory compound rather than a therapeutic product. Published reports have explored its role in lipid disorders, insulin sensitivity, and exercise metabolism, yet no major drug regulator has approved it for medical use. Commercial samples sold under the cardarine name may vary in purity and identity. Analytical confirmation is therefore necessary when the material is discussed in scientific or regulatory contexts. Its classification as a prohibited substance in sport further shapes how it is studied and reported.
A persistent misconception is that cardarine is a fat-burning drug or a safe alternative to anabolic steroids. No approved therapeutic product exists, and human safety data are limited. The tumor findings in rodents remain a central concern in scientific reviews. Products sold online may contain inaccurate labels, impurities, or different compounds entirely, which complicates any assessment of effects. Independent testing of such products has reported frequent mislabeling. For these reasons, discussions in the literature emphasize risks and unknowns rather than benefits.
Cardarine is not approved for human therapeutic use in any major jurisdiction. It appears on the World Anti-Doping Agency Prohibited List as a PPARδ agonist within the hormone and metabolic modulators category. Sports organizations test for it because it has been detected in athlete samples and seized products. Regulatory actions against marketed research chemical versions have occurred in several countries, though enforcement varies. Availability through unregulated channels complicates oversight.

==== Suppression of Cossack autonomy in the Russian Empire ==== Historian Gary Dean Peterson writes: "With all this unrest, Ivan Mazepa of the Ukrainian Cossacks was looking for an opportunity to secure independence from Russia and Poland". In response to Mazepa's alliance with Charles XII of Sweden, Peter I ordered the sacking of the then capital of the Hetmanate, Baturyn. The city was burnt and looted, and 11,000 to 14,000 of its inhabitants were killed. The destruction of the Hetmanate's capital was a signal to Mazepa and the Hetmanate's inhabitants of severe punishment for disloyalty to the Tsar's authority. The Zaporizhian Sich at Chortomlyk, which had existed since 1652, was also destroyed by Peter I's forces in 1709, in retribution for decision of its otaman Kost Hordiyenko, to ally with Mazepa. Under Russian rule, the Cossack nation of the Zaporozhian Host was divided into two autonomous republics of the Russian Tsardom: the Cossack Hetmanate, and the more independent Zaporizhia. These organizations gradually lost their autonomy, and were abolished by Catherine II in the late 18th century. The Hetmanate became the governorship of Little Russia, and Zaporizhia was absorbed into New Russia.
=== Differential diagnoses === The differential diagnoses are extensive and include: Alagille syndrome, alpha-1-antitrypsin deficiency, Byler disease (progressive familial intrahepatic cholestasis), Caroli disease, choledochal cyst, cholestasis, congenital cytomegalovirus disease, congenital herpes simplex virus infection, congenital rubella, congenital syphilis, congenital toxoplasmosis, cystic fibrosis, galactosemia, idiopathic neonatal hepatitis, lipid storage disorders, neonatal hemochromatosis, and total parenteral nutrition-associated cholestasis.
== Adverse effects == Data from phase II and III clinical trials did not detect any severe adverse effects to setipiprant. The authors were unable to identify any pattern of adverse effects that differ from placebo, including subjective reporting of symptoms and objective laboratory monitoring.
=== Removal of additives === In 2011, food blogger and activist Vani Hari noted that Chick-fil-A sandwiches contained nearly 100 ingredients, including peanut oil preserved with tert-butylhydroquinone (TBHQ), made from butane. In October 2012, Chick-fil-A invited Hari to meet with company executives at its headquarters. In December 2013, Chick-fil-A said that it was removing high-fructose corn syrup and artificial dyes, and was testing a new peanut oil. Like other companies, Chick-fil-A does not publicly announce such changes unless already in the news, because it focuses on these ingredients.

Insulin icodec, sold under the brand name Awiqli, is an ultralong-acting basal insulin analogue used in the treatment of diabetes. It is administered by subcutaneous injection once weekly. It was developed by Novo Nordisk. Insulin icodec was designed to provide basal insulin coverage with once-weekly dosing. It is approved for medical use in Canada, the European Union, Australia, and in the United States.
=== Synaptogenesis === BDNF also enhances synaptogenesis. Synaptogenesis is dependent upon the assembly of new synapses and the disassembly of old synapses by β-adducin. Adducins are membrane-skeletal proteins that cap the growing ends of actin filaments and promote their association with spectrin, another cytoskeletal protein, to create stable and integrated cytoskeletal networks. Actins have a variety of roles in synaptic functioning. In pre-synaptic neurons, actins are involved in synaptic vesicle recruitment and vesicle recovery following neurotransmitter release. In post-synaptic neurons they can influence dendritic spine formation and retraction as well as AMPA receptor insertion and removal. At their C-terminus, adducins possess a myristoylated alanine-rich C kinase substrate (MARCKS) domain which regulates their capping activity. BDNF can reduce capping activities by upregulating PKC, which can bind to the adducing MRCKS domain, inhibit capping activity, and promote synaptogenesis through dendritic spine growth and disassembly and other activities.
Diclofenac, sold under the brand name Voltaren among others, is a nonsteroidal anti-inflammatory drug (NSAID) used to treat pain and inflammatory diseases such as gout. It can be taken orally (swallowed by mouth), inserted rectally as a suppository, injected intramuscularly, injected intravenously, applied to the skin topically, or through eye drops. Improvements in pain last up to eight hours. It is also available as the fixed-dose combination diclofenac/misoprostol (Arthrotec) to help protect the stomach; however, proton pump inhibitors such as omeprazole are typically first-line since they are at least as effective as misoprostol, but with better tolerability. Common side effects include abdominal pain, gastrointestinal bleeding, nausea, dizziness, headache, and swelling. Serious side effects may include heart disease, stroke, kidney problems, and stomach ulceration. Use is not recommended in the third trimester of pregnancy. It is likely safe during breastfeeding. Diclofenac is believed to work by decreasing the production of prostaglandins, like other drugs in this class. In 2023, it was the 73rd most commonly prescribed medication in the United States, with more than 9 million prescriptions. It is available as its acid or in two salts, as either diclofenac sodium or potassium.
4-nitrocatechol 4-monooxygenase (EC 1.14.13.166) is an enzyme with systematic name 4-nitrocatechol,NAD(P)H:oxygen 4-oxidoreductase (4-hydroxylating, nitrite-forming).This enzyme catalyses the following chemical reaction:
A documentary film (often called simply a documentary) is a nonfiction motion picture intended to "document reality, primarily for instruction, education or maintaining a historical record". The American author and media analyst Bill Nichols has characterized the documentary in terms of "a filmmaking practice, a cinematic tradition, and mode of audience reception [that remains] a practice without clear boundaries". Research into information gathering, as a behavior, and the sharing of knowledge, as a concept, has noted how documentary movies were preceded by the notable practice of documentary photography. This has involved the use of singular photographs to detail the complex attributes of historical events and continues to a certain degree to this day, with an example being the conflict-related photography achieved by popular figures such as Mathew Brady during the American Civil War. Documentary movies evolved from the creation of singular images in order to convey particular types of information in depth, using film as a medium. Early documentary films, originally called "actuality films", briefly lasted for one minute or less in most cases. While faithfully depicting true events, these releases possessed no narrative structure per se and were of limited interest. Over time, documentaries have evolved to become longer in length and to include more categories of information. Some examples are explicitly educational, while others serve as observational works; docufiction movies notably include aspects of dramatic storytelling that are clearly fictional.

Cardarine is a common name for GW501516, a synthetic PPARδ agonist. It is not a steroid or a selective androgen receptor modulator. It was developed and studied as a research compound for metabolic pathways.
It binds to and activates PPARδ, a nuclear receptor that regulates genes related to fatty acid oxidation and energy use. This activation alters transcription in tissues such as skeletal muscle and liver. The full range of downstream effects in humans is not fully established.
No, cardarine is not known to occur naturally in plants, animals, or humans. It is a synthetic molecule produced for laboratory research. Products labeled as cardarine should therefore be treated as manufactured chemicals with variable purity.
No. Cardarine has not received approval for human therapeutic use in major jurisdictions. It remains an investigational compound.
