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, 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.
Quality assessment for cardarine samples usually combines identity, purity, and impurity testing. Nuclear magnetic resonance spectroscopy and mass spectrometry can confirm molecular structure, while high-performance liquid chromatography estimates purity. Certificates of analysis from testing laboratories may list these results, but they do not establish safety or legality. In the absence of approved manufacturing, products sold online may contain the wrong compound, variable amounts, or unlisted contaminants. Independent verification is therefore central to analytical work and to interpreting any reported biological activity.
Laboratory detection of GW501516 commonly uses liquid chromatography coupled with tandem mass spectrometry. The method can identify the parent compound or its metabolites in urine and blood after sample cleanup. Protein precipitation, solid-phase extraction, or enzymatic hydrolysis may precede analysis, depending on the matrix. Reference standards are required for accurate quantification and confirmation. Because the compound is not approved, testing often occurs in anti-doping, forensic, or research settings rather than routine clinical care. Results are reported with limits of detection and quantification.
Stability of GW501516 depends on form, temperature, light exposure, and moisture. Solid reference material is typically stored frozen or refrigerated in a desiccator and protected from light. Solutions in organic solvents such as dimethyl sulfoxide are often kept frozen in aliquots to reduce freeze-thaw cycling. Aqueous solubility is low, so aqueous stock solutions can be difficult to prepare without cosolvents. Degradation may appear as changes in chromatographic purity or mass spectral signal. Stability studies are needed to establish shelf life for any specific preparation.

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.
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.
Human trials of GW501516 were small and short in duration. They examined lipid levels, glucose handling, and other metabolic markers, but the programs were halted after the animal cancer findings. No approved therapeutic product exists, and published human data are insufficient for establishing long-term safety. Reports of use for athletic performance come mainly from non-clinical settings and cannot be verified through controlled trials. Independent testing of products sold as cardarine has found inconsistent purity and labeling.
Laboratory studies indicate that GW501516 activates PPARδ, a nuclear receptor involved in fatty acid oxidation and energy metabolism. In rodent experiments, treated animals often showed increased endurance and reduced fat mass. These effects were observed under controlled conditions and do not establish safe or effective use in humans. The exact dose-response relationship in humans remains poorly characterized. Species differences in metabolism can affect how results translate across animals and people.
Safety concerns emerged from long-term animal studies. In rodents given the compound for extended periods, researchers found an increased incidence of certain cancers, including liver and bladder tumors. These findings contributed to the discontinuation of clinical development. Whether similar risks apply to short-term or low-level exposure in humans is not established, and controlled human safety data are limited. The relevance of high-dose rodent carcinogenicity findings to human use remains a subject of debate.
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.
Cardarine can be detected in biological samples and product materials using liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS). The method separates compounds by chromatography and identifies them by mass-to-charge transitions, allowing low-level detection in urine or blood. Sample preparation often involves enzymatic hydrolysis, solid-phase extraction, or protein precipitation. Certified reference materials and isotope-labeled internal standards improve quantification. Detection windows depend on metabolism, matrix, and assay sensitivity, so no single universal window applies.
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.
== Overshoot Day == The Global Footprint Network measures the ecological footprint of the world's nations versus each nation's biocapacity. From this it derives an Earth Overshoot Day, an aggregation of the "overshoot day" for each country. The overshoot day is the day that the nation's footprint exceeds its biocapacity. Measurements are made in global hectares (gha). In 2019, the group issued their analysis based on 2016 data. Overshoot days for 135 countries ranged from Qatar on 11 February to Kyrgyzstan on 26 December. Thailand's overshoot day is 28 August. Overshoot days for other ASEAN nations were: Singapore, 12 April; Brunei, 21 May; Malaysia, 1 June; Vietnam, 8 October; Laos, 9 November; Indonesia, 18 December; Myanmar, 25 December. The ecological footprint per person in Cambodia and the Philippines are less than global biocapacity constant (1.63 gha) and thus do not have an overshoot day.
=== Ultrasonic rhinoplasty === Recently, ultrasonic rhinoplasty which was introduced by Massimo Robiony in 2004 has become an alternative to traditional rhinoplasty. Ultrasonic rhinoplasty uses piezoelectric instruments to reshape atraumatically nasal bones, also known as rhinosculpture. Ultrasonic rhinoplasty uses piezoelectric instruments (scrapers rasps, saws) that affect only the bones and the stiff cartilages through ultrasonic vibrations, as the instruments used in dental surgery. The use of piezoelectric instruments requires a more extended approach than the isial one, allowing to visualize the whole bony vault, to reshape it with rhinosculpture or to mobilize and stabilize bones after controlled osteotomies.
Oshkosh, Wisconsin, franchise manager Jim Brajdic said: "Problems back then, including a lawsuit, franchisee discontent, and inconsistencies in the operation, caused the chain to flounder and branches to close." A&W moved to a modern-style franchise agreement that introduced royalty payments and new standards. However, many franchisees refused the revised terms as their 20- or 25-year original agreements expired. In 1980, the number of restaurants had fallen to 1,300 in the United States (mostly in the Midwest and the North West), Asia, and Europe. In 1980, the Singaporean franchisee Temenggong Ltd. had increased the number of restaurants in the country, while nine new restaurants were planned in Malaysia. There were also plans to open restaurants in the Philippines and Hong Kong. Negotiations to sell the chain began in November 1981.

This timeline lists notable events in the history of research into senescence or biological aging, including the research and development of life extension methods, brain aging delay methods and rejuvenation. People have long been interested in making their lives longer and healthier. The most ancient Egyptian, Indian and Chinese books contain reasoning about aging. Ancient Egyptians used garlic in large quantities to extend their lifespan. Hippocrates (c. 460 – c. 370 BCE), in his Aphorisms, and Aristotle (384–322 BCE), in On youth and old age, expressed their opinions about reasons for old age and gave advice about lifestyle. Medieval Persian physician Ibn Sina (c. 980 – 1037), known in the West as Avicenna, summarized the achievements of earlier generations about this issue.

Well-being has traditionally focused on improving physical, emotional and mental quality of life with little understanding of how dependent they all are on financial health. However, financial stress often manifests itself in physical and emotional difficulties that lead to increased healthcare costs and reduced productivity. A more inclusive paradigm for well-being would acknowledge money as a source of empowerment that maximizes physical and emotional health by reducing financial stress. Such a model would provide individuals with the financial knowledge they need, as well as enable them to gain valuable insight and understanding regarding their financial habits, as well as their thoughts, feelings, fears and attitudes about money. Through this work, individuals would be better equipped to manage their money and achieve the financial wellness that is essential for their overall well-being. It has been argued that money cannot effectively "buy" much happiness unless it is used in certain ways, and that "Beyond the point at which people have enough to comfortably feed, clothe, and house themselves, having more money – even a lot more money – makes them only a little bit happier." In his book Stumbling on Happiness, psychologist Daniel Gilbert described research suggesting money makes a significant difference to the poor (where basic needs are not yet met), but has a greatly diminished effect once one reaches middle class (i.e. the Easterlin paradox).
He received a B.S. in physics in 1943. He did not attend graduate school, instead deciding to join the Fighting Vehicles Research Establishment where he served between 1943 and 1947 developing tank fire-control systems.
Half-Life was followed by an expansion pack, Opposing Force, on November 1, 1999, developed by Gearbox Software. Players control US Marine corporal Adrian Shephard, who fights a new group of aliens and black operations units. Opposing Force was received favorably by critics, many citing the game as being as influential on setting expansion pack standards as the original game had been in influencing the overall genre. The game won the Computer Game of the Year Interactive Achievement Award of 2000 from the Academy of Interactive Arts & Sciences.
Athletes competing in power sports, bodybuilding, professional wrestling, mixed martial arts, swimming, baseball, strength sports, track and field, cycling, soccer, weight lifting, skiing and endurance sports have been said to abuse human growth hormone, including in combination with other performance-enhancing drugs such as androgenic anabolic steroids including testosterone, certain products which claim to enhance HGH, and erythropoietin (among others). There has never been an adequately large randomized controlled trial showing definitively that HGH provides benefits to athletes and that there are no significant adverse drug reactions; there have been many small studies and several of these studies were recently reviewed and analyzed in a meta-analysis. While the authors indicated that the meta-analysis was limited by the fact that few of the included studies evaluated athletic performance and by the fact that dosing protocols in the studies may not reflect real-world doses and regimens, their conclusions were as follows:
In the beginning of 1994 with South Africa heading for democratic elections, President Lucas Mangope resisted the elections taking place in Bophuthatswana and opposed reincorporation of the territory into South Africa. This resulted in increasing unrest and 40 people were wounded when Bophuthatswana Defence Force troops opened fire on striking civil servants. Mangope took an increasingly hardline stance, rejected Independent Electoral Commission chairman Judge Johann Kriegler's plea for free political activity in the territory, and fired the staff of the Bophuthatswana Broadcasting Corporation, closing down two television stations and three radio stations. With unrest growing and rumors of ANC supporters massing at Bophuthatswana's borders, Mangope invited General Constand Viljoen, head of the right-wing Afrikaner Volksfront, to immediately assist in keeping the peace. The Afrikaners were hastily rallied and mobilised, including the white supremacist group Afrikaner Weerstandsbeweging (AWB), which took the opportunity to move in and try to restore the apartheid status quo. Uniformed members of the AWB on an armed incursion to the Mmabatho/Mafikeng area shot at unarmed civilians blocking the road, injuring and killing many. They themselves were shot at by members of the Bophuthatswana Defence Force (BDF) and the Police and were forced to retreat. One member of the AWB travelling back in a blue Mercedes Benz shot at some people along the road, which was then followed by members of the Bophuthatswana Police opening fire at the car.

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.
LC-MS/MS is common, often after sample cleanup. The assay targets GW501516 or its metabolites.
