Clinical development has advanced through phase 2 trials in adults with obesity and type 2 diabetes. Reported phase 2 results described substantial average weight reduction over roughly forty-eight weeks of weekly dosing. A phase 3 program is ongoing to confirm efficacy and assess long-term safety. Because the compound has not received regulatory approval, it is not available as a prescription product. Public discussion of retatrutide often conflates trial findings with marketed status, an important distinction when interpreting coverage of the topic.
Retatrutide is a synthetic peptide developed as a single molecule that activates three distinct hormone receptors: GLP-1, GIP, and glucagon. The compound carries the internal designation LY3437943 and was engineered by modifying the backbone of glucose-dependent insulinotropic polypeptide. Its sequence incorporates non-natural amino acids and a fatty acid side chain that extends circulation time. The triple-agonist design aims to combine appetite suppression, improved insulin response, and increased energy expenditure in one agent. Published reports describe it as an investigational product rather than an approved medicine.
Each receptor contributes a different physiological effect. Activation of the GLP-1 receptor slows gastric emptying and reduces appetite signaling in the brain. GIP receptor activity influences insulin secretion and lipid handling, while glucagon receptor stimulation raises energy use and fat oxidation. Combining these pathways is intended to produce weight loss beyond what single- or dual-receptor agonists achieve. Researchers attribute the observed potency to simultaneous engagement of all three targets, though the exact contribution of each receptor to overall effect remains under investigation.
Several questions remain unresolved. It is not yet known whether the compound reduces cardiovascular events or mortality, because outcome studies require long follow-up. The durability of weight reduction after treatment withdrawal is uncertain, and rebound has been observed with other incretin-based therapies. Long-term safety data covering several years are limited. Effects in adolescents, in pregnancy, and in people with significant kidney or liver impairment have not been characterized in published reports.
Randomized studies of retatrutide measure change in body weight as a percentage of baseline, along with absolute weight loss. Glycemic endpoints include hemoglobin A1c and fasting plasma glucose. Investigators also track blood pressure, lipid fractions, and liver fat content to characterize effects beyond weight alone. Trial designs typically use double-blind, placebo-controlled groups with periodic dose escalation, and they record adverse events throughout both treatment and follow-up periods.
Quantification of the peptide in biological samples generally relies on liquid chromatography coupled with tandem mass spectrometry. This approach separates the analyte from matrix components and detects it by mass-to-charge transitions specific to the molecule. Immunoassays offer higher throughput but can cross-react with related peptides and metabolites, so mass spectrometric methods are preferred when structural confirmation is required. Method validation typically addresses accuracy, precision, selectivity, and stability under handling conditions.

In a house without air-conditioning (space heating and/or cooling) refrigerators consume more energy than any other home device. In the early 1990s a competition was held among the major US manufacturers to encourage energy efficiency. Current US models that are Energy Star qualified use 50% less energy than the average 1974 model used. The most energy-efficient unit made in the US consumes about half a kilowatt-hour per day (equivalent to 20 W continuously). But even ordinary units are reasonably efficient; some smaller units use less than 0.2 kWh per day (equivalent to 8 W continuously). Larger units, especially those with large freezers and icemakers, may use as much as 4 kW·h per day (equivalent to 170 W continuously). The European Union uses a letter-based mandatory energy efficiency rating label, with A being the most efficient, instead of the Energy Star.
=== Names === A similar combination is also sold under the brand name Mydayis. Mydayis contains the amphetamines dextroamphetamine sulfate, dextroamphetamine saccharate, amphetamine aspartate monohydrate, and amphetamine sulfate capsule.
White sharks are estimated to swim 2.88–4.86 km/h (1.79–3.02 mph) but can sprint up to 24.12 km/h (14.99 mph). One individual was recorded cruising at a sustained speed of 4.7 km/h (2.9 mph) while migrating, which is fast for a shark and more similar to fast-swimming tuna. White sharks display various surface behaviors. These include spyhopping (poking head out of the surface) to observe an object above the water, as well as 'repetitive aerial gaping' where a spyhopping shark repeatedly gapes its mouth while belly-up, possibly as a sign of frustration after missing a bait. How they sleep is not well understood. At night, one individual was recorded swimming slowly in one direction along a current with its mouth open. The white shark is generally considered to be a solitary species, though aggregations do occur. A 2016 study of sharks around Mossel Bay, South Africa, concluded that white shark associations are generally random with few social interactions. By contrast, a 2019 study found that sharks around Neptune Islands gathered in non-random aggregations. Similarly, a 2022 study of white sharks at Guadalupe Island suggested that individuals may associate so that they can learn from others where to find prey or carcasses to scavenge. White shark aggregations can consist of individuals of a specific age and sex. At Neptune Islands, sightings of subadult females peak during April and May, subadult males in February and again in September, adult females in June, and adult males in September.
=== As a sawmill === When fastened into a special guide frame, a chainsaw can be used as a portable sawmill to cut bulk wood into planks or boards. Such usage is called a chainsaw mill or Alaskan sawmill.
The human body contains, on average, 50–60% water, depending on age, gender and body size, although individuals may have anywhere between 45% and 75%. The U.S. National Academies of Sciences, Engineering, and Medicine recommends a daily intake of 3.7 liters (0.98 U.S. gallons) of water for adult men and 2.7 L (0.71 U.S. gal) for women. The precise amount depends on the level of activity, temperature, humidity, and other factors. Most of this is ingested through foods or beverages other than drinking straight water. Medical literature favors a lower consumption, typically 1 liter of water for an average male, excluding extra requirements due to fluid loss from exercise or warm weather. Healthy kidneys can excrete 0.8 to 1 liter of water per hour, but stress such as exercise can reduce this amount. People can drink far more water than necessary while exercising, putting them at risk of water intoxication (hyperhydration), which can be fatal. The popular claim that "a person should consume eight glasses of water per day" seems to have no real basis in science. Studies have shown that extra water intake, especially up to 500 millilitres (18 imp fl oz; 17 US fl oz) at mealtime, was associated with weight loss. Adequate fluid intake is helpful in preventing constipation.

The most pressing complications of type 1 diabetes are the always-present risks of poor blood sugar control: severe hypoglycemia and diabetic ketoacidosis. Hypoglycemia – typically blood sugar below 70 mg/dL (3.9 mmol/L) – triggers the release of epinephrine, and can cause people to feel shaky, anxious, or irritable. People with hypoglycemia may also experience hunger, nausea, sweats, chills, headaches, dizziness, and a fast heartbeat. Some feel lightheaded, sleepy, or weak. Severe hypoglycemia can develop rapidly, causing confusion, coordination problems, loss of consciousness, and seizure. On average, people with type 1 diabetes experience a hypoglycemia event that requires assistance of another 16–20 times in 100 person-years, and an event leading to unconsciousness or seizure 2–8 times per 100 person-years. The American Diabetes Association recommends treating hypoglycemia by the "15–15 rule": eat 15 grams of carbohydrates, then wait 15 minutes before checking blood sugar; repeat until blood sugar is at least 70 mg/dL (3.9 mmol/L). Severe hypoglycemia that impairs someone's ability to eat is typically treated with injectable glucagon, which triggers glucose release from the liver into the bloodstream. People with repeated bouts of hypoglycemia can develop hypoglycemia unawareness, where the blood sugar threshold at which they experience symptoms of hypoglycemia decreases, increasing their risk of severe hypoglycemic events.
=== Palaeolithic and Iron Age === There is evidence of settlement in the Bristol area from the palaeolithic era, with 60,000-year-old archaeological finds at Shirehampton and St Annes. Stone tools made from flint, chert, sandstone and quartzite have been found in terraces of the River Avon, most notably in the neighbourhoods of Shirehampton and Pill. There are Iron Age hill forts near the city, at Leigh Woods and Clifton Down on either side of the Avon Gorge, and at Kingsweston, near Henbury. Bristol was at that time part of the territory of the Dobunni. Evidence of Iron Age farmsteads has been found at excavations throughout Bristol, including a settlement at Filwood. There are also indications of seasonal occupation of the salt marshes at Hallen on the Severn estuary.
=== Benign prostatic hyperplasia and prostate cancer === Dutasteride is used for treating BPH, colloquially known as an "enlarged prostate". It is approved by the Food and Drug Administration (FDA) in the U.S. for this indication. A 2010 Cochrane review found a 25–26% reduction in the risk of developing prostate cancer with 5α-reductase inhibitor chemoprevention.
Under her leadership, the Thai government has advanced plans to legalize casinos as part of a broader initiative to develop large-scale "entertainment complexes". The policy is intended to attract foreign investment, stimulate tourism, create employment opportunities, and formalize Thailand's widespread underground gambling industry to increase government revenue. Paetongtarn has emerged as a prominent proponent of the initiative, presenting it as a strategy to develop "man-made" tourist destinations and enhance the country's global competitiveness. She has publicly argued that the project will stimulate the economy without using taxpayer funds, as the massive investment required (estimated at THB 100 billion per complex) will come from the private sector. The government projects that the complexes could boost GDP, increase tourist arrivals, and generate between 12 and 40 billion baht in annual tax revenue. In January 2025, the Thai cabinet approved the Entertainment Complex Bill in principle, providing a legal framework for the proposed developments. The bill outlines the creation of multiple integrated resort projects, incorporating five-star hotels, shopping centres, concert venues, theme parks, and other entertainment facilities. The legislation stipulates that casino operations must be limited to no more than 10 per cent of the total floor area of each complex. The policy has faced opposition from civic and religious groups, who warn of potential negative social consequences such as increased crime and gambling addiction.

Retatrutide is an investigational peptide that activates the GLP-1, GIP, and glucagon receptors at the same time. It is being studied for obesity and type 2 diabetes and has not been approved for clinical use. The internal code LY3437943 refers to the same molecule.
Most approved incretin therapies target one or two receptors, while retatrutide engages three. The addition of glucagon receptor activity is intended to raise energy expenditure. This broader mechanism is the subject of ongoing research rather than established practice.
No regulatory agency has approved retatrutide for any indication as of available public information. Development remains in later-stage trials. Availability claims found online should be treated as unverified.
Trials measure percentage change in body weight, absolute weight loss, and glycemic markers such as hemoglobin A1c. They also record blood pressure, lipids, and liver fat. Adverse events are tracked throughout.
