GW501516 acts as a ligand for PPAR delta, a nuclear receptor that regulates transcription of genes involved in fatty acid oxidation and energy use. Activation of this receptor in skeletal muscle shifts metabolism toward fat burning in animal models. The compound does not burn fat directly; it changes gene expression over hours to days. Researchers study it to understand metabolic flexibility and exercise adaptation. Effects observed in rodents are not automatically expected in humans.
Preclinical research reported that GW501516 increased running endurance in mice and improved lipid profiles in some animal species. Early human trials explored effects on high-density lipoprotein cholesterol, triglycerides, and glucose handling, but the program was discontinued. Published human data are sparse and do not establish efficacy for any condition. Studies also examined PPAR delta in cancer biology, with conflicting findings across models. The relationship between receptor activation, tissue context, and disease risk remains an active area of investigation.
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.
Anti-doping laboratories detect GW501516 and its metabolites using liquid chromatography-tandem mass spectrometry. Urine is the most common matrix, though blood and dried blood spots may also be used in some programs. Detection depends on factors such as dose, timing, metabolism, and the sensitivity of the assay. Published methods describe limits of detection in the low nanogram per milliliter range for related compounds. Exact detection windows are not fixed for all situations and remain an area of ongoing study.

=== Drainage of tear film === The lacrimal glands secrete lacrimal fluid, which flows through the main excretory ducts into the space between the eyeball and the lids. When the eyes blink, the lacrimal fluid is spread across the surface of the eye. Lacrimal fluid gathers in the lacrimal lake which is found in the medial part of the eye. The lacrimal papilla is an elevation in the inner side of the eyelid, at the edge of the lacrimal lake. The lacrimal canaliculi open into the papilla. The opening of each canaliculus is the lacrimal punctum. From the punctum, tears will enter the lacrimal sac, then on to the nasolacrimal duct, and finally into the nasal cavity. An excess of tears, as caused by strong emotion, can cause the nose to run. Quality of vision is affected by the stability of the tear film.
Washington was a host city candidate, but the poor state of Northwest Stadium caused the city to combine its bid with nearby Baltimore's M&T Bank Stadium, which was unsuccessful. Other cities eliminated from the final hosting list were Cincinnati, Denver, Nashville, Orlando, and Edmonton. Ottawa's candidate venue, TD Place Stadium, was eliminated early on for insufficient capacity. Eight of the metropolitan areas involved had previously hosted World Cup matches (Dallas, Los Angeles, San Francisco Bay Area, New York/New Jersey, and Boston in 1994; Guadalajara and Mexico City in both 1970 and 1986; Monterrey in 1986), but none of the stadiums used in the 1994 FIFA World Cup were used in this tournament (though Gillette Stadium and MetLife Stadium were located at the same sites as two of the 1994 venues, Foxboro Stadium and Giants Stadium respectively). Soldier Field in Chicago, the Cotton Bowl in Dallas, and the Rose Bowl in Pasadena (Los Angeles area) were the only stadiums in the bidding process to have hosted matches in 1994, but none of them were selected. Estadio Azteca in Mexico City was the only stadium in this tournament that had previously been used for a World Cup, in both 1970 and 1986; it thus became the only stadium to be used for three World Cups. FIFA's rules on stadium sponsorships required venues to use alternative names for the duration of the tournament, shown in parentheses below. The capacity is based on information published by FIFA.
=== Cancer === Lung cancer-specific VOCs are 1-propanol, endogenous primary alcohol, and pentane. Pentane's presence in exhaled breath of patients has been hypothesized to originate from the increased peroxidation of fatty acids seen in severe lung disease. Foul-smelling p-cresol was solely found in colorectal and gastric cancer, expected to be caused by cancer's alteration of the microbiome. No singular compound could be exclusively considered a biomarker, but VOCs patterns observed may aid in distinguishing between certain diseases.

Tamago kake gohan (卵かけご飯; lit. 'egg on rice'), abbreviated TKG, is a popular Japanese breakfast food consisting of cooked Japanese rice topped or mixed with raw egg and soy sauce. It is sometimes referred to simply as tamago gohan (egg rice), tamago kake meshi (egg on rice/food), tamago bukkake gohan (egg splashed onto rice), or other variations. The dish has sometimes been referred to as the "soul food of the Japanese", characterized by Japan's exceptionally high standards of egg hygiene which minimize the risk of Salmonella poisoning from raw eggs. This allows the cultural practice of consuming raw eggs, combined with the staple food of rice, to flourish.
=== Agriculture === For plants to properly grow in dry areas they will need a usable xerotolerant microbiome. In desert plants xerophiles are set in a plant's microbiome helping with its water management.

It binds to and activates PPAR delta, a nuclear receptor that controls expression of genes related to fatty acid oxidation. This mechanism can alter energy metabolism in animal models. It is not a direct stimulant or fat-burning enzyme.
Early-stage trials examined lipid and glucose markers, but the development program was discontinued. Published human results are limited and do not support approved use for any indication. Claims of performance or health benefits remain unproven.
Yes. Laboratories use LC-MS/MS to detect GW501516 and its metabolites in urine. Detection depends on timing and sensitivity, but the substance is banned at all times.
Legal status varies by country, but cardarine is not approved as a medicine in major jurisdictions. It is often sold as a research chemical, a category that may not be lawful for human use. Buyers should check local laws and product labels carefully.
