Human evidence remains limited to controlled studies. A phase 2 trial in adults with obesity reported large, dose-dependent reductions in body weight over 48 weeks, with gastrointestinal events as the most frequently recorded adverse effect. Phase 3 programs designated TRIUMPH, for obesity, and TRANSCEND, for type 2 diabetes, are intended to confirm efficacy and to characterize safety in larger populations. Related studies are examining conditions such as knee osteoarthritis in people with obesity and metabolic liver disease. Open questions include long-term tolerability, effects on lean mass, and what happens after treatment is stopped.
Retatrutide is an investigational synthetic peptide that acts on three receptor targets at once: glucose-dependent insulinotropic polypeptide, glucagon-like peptide-1, and glucagon. It is developed by Eli Lilly and appears in the literature and in trial registries under the code LY3437943. The molecule belongs to a class of engineered peptides designed to resist rapid breakdown and permit infrequent subcutaneous administration. No regulatory agency has approved it for clinical use, and all available human data come from controlled trials rather than from routine practice.
Several questions about the compound remain unresolved. The durability of weight reduction after treatment stops, the frequency of gastrointestinal side effects, and the long-term cardiovascular profile are topics of ongoing study. Regulatory submissions and phase 3 trial outcomes have not been fully reported in the public literature. Because most available data come from controlled trials rather than general-population use, conclusions about effectiveness outside study settings are provisional. The distinction between established findings and open questions matters when interpreting early coverage of the drug.
Retatrutide is an investigational peptide developed by a pharmaceutical company as a multi-receptor agonist for treating obesity and type 2 diabetes. The compound emerged from research into gut-hormone analogues that act on several receptors simultaneously rather than on a single target. Early preclinical work examined how combined activity at three distinct receptors might produce greater metabolic effects than single-receptor compounds. Published phase 2 results have described substantial reductions in body weight among participants, although the compound remains unapproved in most jurisdictions as of the mid-2020s.
Pharmacologically, retatrutide acts as a triple agonist at the glucagon-like peptide-1 receptor, the glucose-dependent insulinotropic polypeptide receptor, and the glucagon receptor. Activation of the first two receptors is associated with improved insulin secretion and reduced appetite. The glucagon receptor component is thought to increase energy expenditure, a mechanism that distinguishes this molecule from dual-agonist compounds. Researchers continue to investigate how the three activities interact and whether the combined profile offers advantages that justify additional clinical testing.

Mechanistic proposals link each receptor to a different physiological role. Activation of the glucose-dependent insulinotropic polypeptide and glucagon-like peptide-1 receptors is associated with reduced appetite, slower gastric emptying, and glucose-dependent insulin release. Glucagon receptor signaling, by contrast, is associated with increased energy expenditure and altered lipid handling, though it can also raise blood glucose. The design intent is to balance these contributions so that weight reduction is enhanced without unacceptable glycemic trade-offs. How well that balance holds across individuals is not fully resolved.
Published information places retatrutide in clinical development rather than on the market as an approved therapy. Early-stage and mid-stage trials have examined tolerability and changes in body weight, and larger studies continue to report results over time. Open questions include the durability of effects after treatment stops, the composition of weight lost, and cardiovascular outcomes over long periods. Statements about definitive benefit should therefore be treated as provisional. Regulatory status varies by jurisdiction and changes as applications are reviewed.
Retatrutide is an investigational synthetic peptide designed to activate three distinct receptor systems within a single molecule. Its pharmacological profile combines activity at the glucose-dependent insulinotropic polypeptide receptor, the glucagon-like peptide-1 receptor, and the glucagon receptor. This arrangement places it within a broader class of agents often described as multi-agonists, which contrast with compounds that engage one or two targets. Research interest centers on whether simultaneous signaling produces effects that single-receptor agonists cannot achieve alone. A single molecular entity also simplifies manufacturing and delivery logistics compared with combining separate agents.

多肽类化合物的表征通常依赖色谱与质谱联用技术。反相高效液相色谱用于评估纯度与有关物质，质谱用于确认分子量，肽图分析通过酶解碎片比对验证一级结构。这些手段组合使用，可以把目标产物与降解产物或类似物区分开来。单一方法往往不足以完成完整确认。
Development has progressed through early- and mid-stage human studies in adults with obesity and with type 2 diabetes. Published phase 2 data reported reductions in body weight and improvements in glycemic markers over the treatment period. No regulatory agency has approved the compound for any indication, and it remains available only within controlled research settings. Whether benefits observed in trials translate into durable outcomes after treatment stops is not yet established.
Retatrutide is an investigational synthetic peptide that acts as an agonist at three distinct G protein-coupled receptors. It combines activity at the glucagon-like peptide-1 receptor, the glucose-dependent insulinotropic polypeptide receptor, and the glucagon receptor within a single molecule. This multi-receptor profile distinguishes it from earlier incretin-based compounds that engage one or two of these pathways. Researchers designed the molecule to test whether simultaneous activation produces greater metabolic effects than single or dual agonism alone.
=== Combined malonic and methylmalonic aciduria (CMAMMA) === In combined malonic and methylmalonic aciduria (CMAMMA), mutations in the ACSF3 gene impair the mitochondrial enzyme acyl-CoA synthetase family member 3 (ACSF3), disrupting the conversion of methylmalonic acid to methylmalonyl-CoA and its entry into the citric acid cycle. This leads to accumulation of methylmalonic acid, reduced methylmalonyl-CoA levels and decreased lysine methylmalonylation compared to healthy controls.
=== Equipped bench press === For the bench press, there are single-ply and multi-ply bench shirts that work similarly to a squat suit. It acts as artificial pectoral muscles and shoulder muscles for the lifter. It resists the movement of the bench press by compressing and building elastic energy. When the bar is still and the official gives the command to press the compression and elastic energy of the suit aids in the speed of the lift, and support of the weight that the athlete would not be able to provide without the bench shirt.
The main etiologic factor of ACC is unknown, although families with Li–Fraumeni syndrome, caused by an inherited inactivation mutation in TP53, have increased risk. Several genes have been shown to be recurrently mutated, including TP53, CTNNB1, MEN1, PRKAR1A, RPL22, and DAXX. The telomerase gene TERT is often amplified while ZNRF3 and CDKN2A are often homozygously deleted. The genes h19, insulin-like growth factor II (IGF-II), and p57kip2 are important for fetal growth and development. They are located on chromosome 11p. Expression of the h19 gene is markedly reduced in both nonfunctioning and functioning adrenal cortical carcinomas, especially in tumors producing cortisol and aldosterone. Also, a loss occurs of activity of the p57kip2 gene product in virilizing adenomas and adrenal cortical carcinomas. In contrast, IGF-II gene expression has been shown to be high in adrenal cortical carcinomas. Finally, c-myc gene expression is relatively high in neoplasms, and it is often linked to poor prognosis. Bilateral adrenocortical tumors are less common than unilateral. The majority of bilateral tumours can be distinguished according to size and aspect of the nodules: primary pigmented nodular adrenocortical disease, which can be sporadic or part of Carney complex, and primary bilateral macro nodular adrenal hyperplasia.Metastasis is most commonly to the liver and lung.
With the fall of Babylon to the rising Achaemenid Persian Empire, king Cyrus the Great issued a proclamation known as the Edict of Cyrus, encouraging the exiles to return to their homeland after the Persians raised it as an autonomous Jewish-governed province named Yehud. Under the Persians (c. 539–332 BCE), the returned Jewish population restored the city and rebuilt the Temple in Jerusalem. The Cyrus Cylinder is controversially cited as evidence for Cyrus allowing the Judeans to return. The returnees showed a "heightened sense" of their ethnic identity and shunned exogamy, which was treated as a "permissive reality" in Babylon. Circumcision was no longer a significant ethnic marker, with increased emphasis on genealogical descent or faith in Yahweh. Jason A. Staples argues that the majority of contemporary Jews, regardless of theology, wished for the reunion of northern Israelites and southern Jews and did not completely appropriate the Israel identity for themselves.
=== Crohn's disease === Three phenotypes, or categories of disease, are present in Crohn's disease: stricturing disease (which causes narrowing of the bowel), penetrating disease (which causes fistulae or abnormal connections of the bowel), and inflammatory disease (which primarily causes inflammation).

Brazil supplies 99% of global açaí berries, producing 1.7 million tons in 2024. Other producers include Colombia (0.35%) and Bolivia (0.006%). The state of Pará grows around 95% of Brazilian açaí berries, and produced more than 1.2 million tons of açaí in 2019.
=== Transplant === In some cases, people can receive transplants of the pancreas or isolated islet cells to restore insulin production and alleviate diabetic symptoms. Transplantation of the whole pancreas is rare, due in part to the few available donor organs, and to the need for lifelong immunosuppressive therapy to prevent transplant rejection. The American Diabetes Association recommends pancreas transplantation only in people who also require a kidney transplant, or who struggle to perform regular insulin therapy and experience repeated severe side effects of poor blood sugar control. Most pancreas transplants are done simultaneously with a kidney transplant, with both organs from the same donor. The transplanted pancreas continues to function for at least five years in around three-quarters of recipients, allowing them to stop taking insulin. Transplantations of islets alone have become increasingly common. Pancreatic islets are isolated from a donor pancreas, then injected into the recipient's portal vein from which they implant onto the recipient's liver. In nearly half of recipients, the islet transplant continues to work well enough that they still do not need exogenous insulin five years after transplantation. If a transplant fails, recipients can receive subsequent injections of islets from additional donors into the portal vein.
The heart wall is made up of three layers: the inner endocardium, middle myocardium and outer epicardium. These are surrounded by a double-membraned sac called the pericardium. The innermost layer of the heart is called the endocardium. It is made up of a lining of simple squamous epithelium and covers heart chambers and valves. It is continuous with the endothelium of the veins and arteries of the heart, and is joined to the myocardium with a thin layer of connective tissue. The endocardium, by secreting endothelins, may also play a role in regulating the contraction of the myocardium.
When there is an injury to a blood vessel, the endothelial cells can release various vasoconstrictor substances, such as endothelin and thromboxane, to induce the constriction of the smooth muscles in the vessel wall. This helps reduce blood flow to the site of injury and limits bleeding.

It is an investigational peptide that activates three hormone receptors: GIP, GLP-1 and glucagon. It is being studied mainly for obesity and type 2 diabetes, and it is not approved for any clinical use. Published information comes from controlled trials rather than from general practice.
No. As of the most recent public information it remains investigational in every jurisdiction. Material sold under this name outside trials is a research chemical, not an approved medicine. Current status should always be checked against regulator notices.
Dual agonists act on two receptors, usually GIP and GLP-1. Retatrutide adds glucagon receptor activity, which is associated with increased energy expenditure. Whether that third component adds clinically meaningful benefit over dual agonism remains an open question.
It is designed as a triple agonist acting on the GLP-1, GIP, and glucagon receptors. This combination is intended to influence appetite, insulin secretion, and energy expenditure. Single-receptor and dual-receptor compounds act on a narrower set of targets.
