Everything below concerns fatty acid oxidation. We keep the language plain, cite what the science says, and separate well-supported claims from open questions.
Last reviewed on 2025-12-05. Where a claim depends on a specific study, the study is described rather than over-claimed.
Cardarine is a common name for GW501516, an investigational compound developed in the 1990s for metabolic conditions. It acts as an agonist at peroxisome proliferator-activated receptor delta, a nuclear receptor involved in lipid and energy metabolism. The compound is frequently mislabeled as a selective androgen receptor modulator, or SARM, but its molecular target is different. GW501516 reached early clinical testing before development was discontinued. It has no approved therapeutic use in any country. The name cardarine is not a formal international nonproprietary name.
Regulatory treatment varies, but cardarine is not approved as a medicine. Sports authorities list GW501516 as a prohibited substance, and it is banned at all times under the World Anti-Doping Agency code. Many countries restrict sales for human consumption, while online vendors market it as a research chemical. Such products may lack purity data, and their actual contents can differ from the label. Purchasing or possessing cardarine may carry legal consequences depending on jurisdiction. The compound is not a dietary supplement ingredient in regulated markets.
Clinical development stopped after rodent studies showed tumors at multiple sites. Whether those findings predict human cancer risk remains an open question, but they led sponsors to discontinue programs. Human safety data are limited to small, short-term studies that were not designed to assess cancer risk. Reported effects in those studies included changes in blood lipids, but the evidence is insufficient for medical use. Long-term consequences of nonmedical use are not well characterized. Questions about dose, duration, and individual susceptibility remain unresolved.
Cardarine is a common name for GW501516, a synthetic compound studied for its effects on lipid and glucose metabolism. It functions as an agonist at peroxisome proliferator-activated receptor delta, or PPARδ, a nuclear receptor that influences gene expression. The molecule is not a steroid, nor is it a selective androgen receptor modulator. It is also known in research and sports literature as GW-501516 and endurobol. Early laboratory work examined its metabolic activity in cell cultures and animal models.
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.
| Property | Value | Notes |
|---|---|---|
| Common synonyms | GW501516; GW-1516; endurobol | GW501516 is the research code |
| Drug class | PPARδ agonist | Not a selective androgen receptor modulator |
| Molecular formula | C21H18F3NO3S2 | Established chemical formula |
| Molar mass | 453.5 g/mol | Calculated from the formula |
| Regulatory status | Prohibited in sport; not approved as medicine | Status varies by country |
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.
GW501516 acts as an agonist at peroxisome proliferator-activated receptor delta, a nuclear receptor involved in transcription of genes related to lipid handling and energy use. Activation of PPARδ can shift skeletal muscle toward greater fatty acid oxidation in animal models, which is one reason it drew interest for metabolic disease and exercise research. The exact downstream effects depend on tissue, species, dose, and duration. Human data are sparse, so many proposed benefits remain hypotheses rather than established clinical outcomes.
Laboratory studies have examined GW501516 in cell cultures and rodents for conditions such as dyslipidemia, insulin resistance, and obesity. Some trials in humans were initiated, but development was discontinued after preclinical findings raised concerns about cancer in certain models. Those findings do not prove that the compound causes cancer in people, but they contributed to regulatory caution. Later reviews often describe the evidence as preliminary and insufficient for assessing long-term safety.
In the fitness and bodybuilding literature, cardarine is frequently discussed as an endurance agent or fat-loss compound, although such claims are not supported by robust clinical evidence. Online descriptions often mix animal data, user anecdotes, and marketing language. Researchers who study PPARδ agonists distinguish between receptor activation in controlled experiments and unsupervised use of unverified products. The latter introduces unknown purity, dose, and interactions, making reported experiences difficult to interpret scientifically.
=== Magnesium sulfate overdose === It is also used to counteract an overdose of Epsom salts magnesium sulfate, which is often administered to pregnant women in order to prophylactically prevent seizures (as in a patient experiencing preeclampsia). Magnesium sulfate is no longer given to pregnant women who are experiencing premature labor in order to slow or stop their contractions (other tocolytics are now used instead due to better efficacy and side effect profiles). Excess magnesium sulfate results in magnesium sulfate toxicity, which results in both respiratory depression and a loss of deep tendon reflexes (hyporeflexia).
== Death == Shortly after midnight on January 19, 2005, Bentley was driving alone when he was killed in a single-car accident in southern California's Ventura County. He was driving on Highway 118 near Simi Valley (30 miles northwest of Los Angeles). Witnesses to the accident stated that Bentley's vehicle was travelling at a high speed towards the Rocky Peak Fire Road off ramp. After running through a stop sign, the vehicle went through a chain-link fence situated across the street and rolled down an embankment. Bentley was ejected from the vehicle into traffic where five cars struck him. He sustained multiple blunt force injuries and was pronounced dead at 12:23 a.m. Bentley was survived by his two daughters and his mother Loyce Bentley. A memorial service for Bentley was held at Forest Lawn Memorial Home in Hollywood Hills, on January 24, 2005. He was buried at Forest Lawn Memorial Park, Hollywood Hills.
King William I appointed Otto von Bismarck as the Minister President of Prussia in 1862. Bismarck successfully concluded the war with Denmark in 1864; the subsequent decisive Prussian victory in the Austro-Prussian War of 1866 enabled him to create the North German Confederation which excluded Austria. After the defeat of France in the Franco-Prussian War, the German princes proclaimed the founding of the German Empire in 1871. Prussia was the dominant constituent state of the new empire; the King of Prussia ruled as its Emperor (Kaiser), and Berlin became its capital. In the Gründerzeit period following the unification of Germany, Bismarck's foreign policy as chancellor of Germany secured Germany's position as a great nation by forging alliances and avoiding war. However, under Wilhelm II, Germany took an imperialistic course, leading to friction with neighbouring countries. A dual alliance was created with the multinational realm of Austria-Hungary; the Triple Alliance of 1882 included Italy. Britain, France and Russia also concluded alliances to protect against Habsburg interference with Russian interests in the Balkans or German interference against France. At the Berlin Conference in 1884, Germany claimed several colonies including German East Africa, German South West Africa, Togoland, and Kamerun. Germany later expanded its colonial empire to include holdings in the Pacific and China.

The method was tested on 96% spirit vodka. In this method, melted wax (stearic acid) is stirred, and the alcoholic drink is poured in. The solution dissipates and becomes drops containing alcohol and wax. The drops that solidify constitute alcohol powder.
==== Hypoglycemic unawareness ==== Recurrent episodes of hypoglycemia can lead to hypoglycemic unawareness, or the decreased ability to recognize hypoglycemia. As diabetics experience more episodes of hypoglycemia, the blood glucose level which triggers symptoms of hypoglycemia decreases. In other words, people without hypoglycemic unawareness experience symptoms of hypoglycemia at a blood glucose of about 55 mg/dL (3.0 mmol/L). Those with hypoglycemic unawareness experience the symptoms of hypoglycemia at far lower levels of blood glucose. This is dangerous for a number of reasons. The hypoglycemic person not only gains awareness of hypoglycemia at very low blood glucose levels, but they also require high levels of carbohydrates or glucagon to recover their blood glucose to normal levels. These individuals are also at far greater risk of severe hypoglycemia. While the exact cause of hypoglycemic unawareness is still under research, it is thought that these individuals progressively begin to develop fewer adrenergic-type symptoms, resulting in the loss of neuroglycopenic-type symptoms. Neuroglycopenic symptoms are caused by low glucose in the brain, and can result in tiredness, confusion, difficulty with speech, seizures, and loss of consciousness. Adrenergic symptoms are caused by the body's reaction to low glucose in the brain, and can result in fast heart rate, sweating, nervousness, and hunger. See section above on Signs and Symptoms for further explanation of neuroglycopenic symptoms and adrenergic symptoms.
== Biological control of nematodes == This fungus has been investigated as a biocontrol agent of agriculturally important nematodes, most notably those responsible for gastrointestinal infection of grazing animals. These parasitic infections are commonly treated with anthelmintic agents including benimidazole, levamisole and invermectin. However, increasing levels of anthelmintic resistance have been observed, driving the search for new treatment and prevention options. Larvae of animal-pathogenic nematodes are found in soil. The prospect of treating contaminated soils with nematode pathogenic fungi such as H. anguillulae has shown potential to reduce nematode populations. However, the fungus does not persist in soil following the elimination of nematode populations, potentially limiting its use as a sustainable biocontrol agent.
== Diagnosis == Blood tests for the diagnosis of diabetic ketoacidosis measure glycemia (sugar level), pH (blood acidity), and ketone bodies. As urgent medical treatment is often required when DKA is suspected, the tentative diagnosis can be made based on clinical history and by calculating the anion gap from the basic metabolic panel, which would demonstrate a high anion-gap metabolic acidosis along with high glucose levels. This allows timely treatment with fluids and insulin well before direct serum ketone body testing results arrive. Urine ketone testing is also available but this cannot easily distinguish DKA from other causes of ketonuria without more context. Diagnostic workup should also include tests to determine any potential infectious trigger for DKA such as pneumonia or UTI.

== Mechanism of action == Loop diuretics are 90% bonded to proteins and are secreted into the kidney's proximal convoluted tubule through organic anion transporter 1 (OAT-1), OAT-2, and ABCC4. Loop diuretics act on the Na+-K+-2Cl− symporter (NKCC2) located on the luminal membrane of cells along the thick ascending limb of loop of Henle to inhibit sodium, chloride and potassium reabsorption. This is achieved by competing for the Cl− binding site. Loop diuretics also inhibit NKCC2 at the macula densa, reducing sodium transported into macula densa cells. This stimulates the release of renin, which through renin–angiotensin system, increases fluid retention in the body, increases the perfusion of glomerulus, thus increasing glomerular filtration rate (GFR). At the same time, loop diuretics inhibit the tubuloglomerular feedback mechanism so that increase in salts at the lumen near macula densa does not trigger a response that reduces the GFR. Loop diuretics also inhibit magnesium and calcium reabsorption in the thick ascending limb. Absorption of magnesium and calcium are dependent upon the positive voltage at the luminal side and less positive voltage at the interstitial side with transepithelial voltage gradient of 10 mV. This causes the magnesium and calcium ions to be repelled from luminal side to interstitial side, promoting their absorption. The difference in voltage in both sides is set up by potassium recycling through renal outer medullary potassium channel.

No. Cardarine is GW501516, a PPARδ agonist, while SARMs act on androgen receptors. The two classes are often grouped in informal discussions despite different mechanisms.
No. It has no approved medical indication in any country. Regulatory agencies have not cleared it for treatment or prevention of any condition.
Early clinical work stopped after rodent carcinogenicity findings. Those animal results raised concerns about long-term human risk, although direct human evidence is lacking. The human relevance of the tumors remains an open scientific question.
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.
