If you have been reading about anti-doping 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 2026-03-29. Where a claim depends on a specific study, the study is described rather than over-claimed.
Products sold as cardarine have been found to contain incorrect compounds, variable amounts, or no active ingredient at all. Independent testing is required to verify identity and purity. Common analytical approaches include high-performance liquid chromatography, mass spectrometry, and nuclear magnetic resonance for structural confirmation. These methods can distinguish GW501516 from related PPAR agonists and from unrelated steroids. For regulators and researchers, such verification is central to interpreting both biological results and adverse event reports.
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.
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.
Anti-doping laboratories identify GW501516 and its metabolites using liquid chromatography-tandem mass spectrometry. Urine is the usual matrix, and detection can occur after the parent compound has cleared from blood. The exact detection window depends on dose, formulation, individual metabolism, and assay sensitivity. Because the compound is prohibited at all times, athletes are subject to testing in and out of competition. Analytical methods continue to improve as new metabolites and designer analogs are characterized.

== Mechanism of action == Immunoliposomes use similar functionality as liposomes with the added measure of conjugating monoclonal antibodies and their fragments to the liposomes. The use of antibodies allow for easy targeting as they can recognize many different types of antigens. Diseased cells typically contain more antigens than healthy cells, which is how antibodies are able to appropriately target certain extracellular domains (depending on antigen overexpression) and kill diseased cells. Liposomal drug delivery combined with antibodies as a targeting ligand are what help immunoliposomes function as an effective drug carrier.
== History == Seer was founded in 2017 by Omid Farokhzad, Philip Ma, and Robert Langer, based on nanoparticle technologies developed in Farokhzad’s laboratory at Brigham and Women’s Hospital, Harvard Medical School. Early investors included Maverick Capital, aMoon Fund, Wing VC, T. Rowe Price, and Fidelity. In September 2020, Seer spun off PrognomiQ to focus on clinical applications, such as developing a liquid biopsy blood test for early lung cancer detection. Philip Ma became President and CEO of PrognomiQ. Farokhzad serves as chair of the board of directors of PrognomiQ. Seer retains approximately 19% ownership in the company. On December 4, 2020, Seer completed its initial public offering, raising approximately $336.2 million in proceeds. Underwriters included J.P. Morgan, Morgan Stanley, Bank of America Securities, and Cowen. Seer launched the Proteograph Product Suite in January 2021, which included the SP100 automation instrument and the Proteograph RISE assay kit. In June 2023, the company introduced the Proteograph XT assay kit, which increased system throughput by 150%. In May 2025, Seer released a high-throughput version of the Proteograph Product Suite, including the Proteograph ONE Assay and SP200 Automation Instrument. The system supports processing of up to 1,000 samples per week and is designed for large-scale proteomic studies.

24997Bk + 4820Ca → 297117* → 294117 + 3 n → 290115 + α → 286113 + α 24997Bk + 4820Ca → 297117* → 293117 + 4 n → 289115 + α → 285113 + α The new isotopes 285113 and 286113 produced did not overlap with the previously claimed 282113, 283113, and 284113, so this reaction could not be used as a cross-bombardment to confirm the 2003 or 2006 claims. In March 2010, the Riken team again attempted to synthesise 274Rg directly through the 205Tl + 70Zn reaction with upgraded equipment; they failed again and abandoned this cross-bombardment route. After 450 more days of irradiation of bismuth with zinc projectiles, Riken produced and identified another 278113 atom in August 2012. Although electricity prices had soared since the 2011 Tōhoku earthquake and tsunami, and Riken had ordered the shutdown of the accelerator programs to save money, Morita's team was permitted to continue with one experiment, and they chose their attempt to confirm their synthesis of element 113. In this case, a series of six alpha decays was observed, leading to an isotope of mendelevium:
==== Serbia ==== Taco Bell opened its first store in Serbia, in the capital city of Belgrade, on November 20, 2025, at the Ušće Shopping Center. Serbia is the second country of the former Yugoslavia in which Taco Bell is present. Second opened in Novi Sad.
=== Cognition === Vascular health is critical in maintaining cognitive function. IGF-1 plays an essential role in vascular remodelling of the brain and supports cognitive retention. Metabolic IGF-1 levels tend to reduce with age and this reduction appears to be a major contributor to cognitive impairment in older populations. Low or deficient IGF-1 levels can be normalized by cGP, restoring its vascular function. Studies evaluating cGP, IGF-1 and IGFBP3 levels suggest that cGP concentration and cGP/IGF-1 molar ratio were positively associated suggesting that older people with higher plasma cGP concentration (and cGP/IGF-1 molar ratio) have better memory/cognitive retention.
Growth hormone therapy refers to the use of growth hormone (GH) as a prescription medication—it is one form of hormone therapy. Growth hormone is a peptide hormone secreted by the pituitary gland that stimulates growth and cell reproduction. In the past, growth hormone was extracted from human pituitary glands. Growth hormone is now produced by recombinant DNA technology and is prescribed for a variety of reasons. GH therapy has been a focus of social and ethical controversies for 50 years. This article describes the history of GH treatment and the current uses and risks arising from GH use. Other articles describe GH physiology, diseases of GH excess (acromegaly and pituitary gigantism), deficiency, the recent phenomenon of HGH controversies, growth hormone in sports, and growth hormone for cows.

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.
Anti-doping laboratories use LC-MS/MS to detect GW501516 and its metabolites, usually in urine. The method can identify the parent compound at low concentrations. Detection windows vary with dose and individual factors.
No, cardarine has no approved medical uses in major jurisdictions. Early research explored metabolic conditions, but those programs were discontinued. It is not a registered treatment for any disease.
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.
