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.
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.
Analytical laboratories typically identify cardarine and its metabolites using liquid chromatography-tandem mass spectrometry. Urine is a common matrix in anti-doping testing, while blood and tissue may be used in research settings. Detection windows depend on the assay, the sample matrix, and the compound's metabolism. Because cardarine is extensively metabolized, laboratories often target specific metabolites to improve sensitivity and confirmation. Reference standards are required for reliable quantification. Method validation includes checks for selectivity, linearity, and carryover.
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.

He claimed that Mubadala attempted to take over all shares of the founders, and “intentionally delayed” transferring units to them. Getir's founders also stated that Mubadala attempted to back off from the deal at the end of 2024. They appealed to the Enterprise Chamber of the Amsterdam Court of Appeal, and said to take a legal action in Turkey and the UK as well. Mubadala was planning to propose an alternative plan, which it said was already approved by Getir's independent directors. But Salur expressed his intent to “continue fighting” the restructuring plan. On 30 January 2025, Salur removed Getir's CEO Batuhan Gultakan from his position without giving specific reasons. Sources revealed that the move was taken due to Gultakan's full support towards Mubadala. In December 2024, Mubadala announced a partnership with Silver Rock Financial LP in which Mubadala Capital acquired a 42% stake in the company. Mubadala Capital acquired the Canadian asset manager CI Financial Corp. in August 2025 for $8.9 billion. Also in August 2025, Mubadala invested $35 million for a 12.8% stake into Paragraf, a British technology company. Mubadala Capital acquired the outdoor advertising company Clear Channel Outdoor in February 2026 for $6.2 billion.
== Medical uses == Cilostazol is approved for the treatment of intermittent claudication in the United States and United Kingdom. If no improvement is seen after 3 months, stopping the medication is reasonable. Cilostazol is also used for secondary stroke prevention, though to date no regulatory body has approved it specifically for that indication.
== Chemerin-derived peptides == A particular synthetic chemerin-derived peptide, termed C15, was developed at Oxford University. It showed anti-inflammatory activities. Intraperitoneal administration of C15 (0.32 ng/kg) to mice before zymosan challenge conferred significant protection against zymosan-induced peritonitis, suppressing neutrophil (63%) and monocyte (62%) recruitment with a concomitant reduction in proinflammatory mediator expression. C15 was found to promote phagocytosis and efferocytosis in peritoneal macrophages at picomolar concentrations. C15 enhanced macrophage clearance of microbial particles and apoptotic cells by factor of 360% in vitro. Another chemerin-derived peptide, termed C-20, was developed at the Shenzhen Institute of Advanced Technology. Administration C-20 uncovered its high affinity binding to chemerin receptors CMKLR1 and GPR1, mimicking chemerin’s activity but with lower potency. C-20 triggered receptor internalization, promoted chemotaxis, and mildly suppressed hormone production (testosterone and progesterone), suggesting its potential as a tool to study chemerin-related signaling pathways.

== Adverse effects == The most widely reported side effect of glycyrrhizin use via consumption of black liquorice is reduction of blood potassium levels, which can affect body fluid balance and function of nerves. Chronic consumption of black licorice, even in moderate amounts, is associated with an increase in blood pressure, may cause irregular heart rhythm, and may have adverse interactions with prescription drugs. In extreme cases, death can occur as a result of excess consumption.
In biochemistry, medicine, and related sciences, inositol generally refers to myo-inositol (formerly meso-inositol), the most important stereoisomer of the chemical compound cyclohexane-1,2,3,4,5,6-hexol. Its formula is C6H12O6; the molecule has a ring of six carbon atoms, each with a hydrogen atom and a hydroxy group (–OH). In myo-inositol, two of the hydroxyls, neither adjacent nor opposite, lie above the respective hydrogens relative to the mean plane of the ring. The compound is a carbohydrate, specifically a sugar alcohol with half the sweetness of the disaccharide sucrose (table sugar). It is one of the most ancient components of living beings with multiple functions in eukaryotes, including structural lipids and secondary messengers. A human kidney makes about two grams per day from glucose, but other tissues synthesize it too. The highest concentration is in the brain, where it plays an important role in making other neurotransmitters and some steroid hormones bind to their receptors. In other tissues, it mediates cell signal transduction in response to a variety of hormones, neurotransmitters, and growth factors and participates in osmoregulation. In most mammalian cells the concentrations of myo-inositol are 5 to 500 times greater inside cells than outside them. The other naturally occurring stereoisomers of cyclohexane-1,2,3,4,5,6-hexol are scyllo-, muco-, D-chiro-, L-chiro-, and neo-inositol, although they occur in minimal quantities compared to myo-inositol. The other possible isomers are allo-, epi-, and cis-inositol.

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.
