If you have been reading about AOD-9604 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 2025-09-24. Where a claim depends on a specific study, the study is described rather than over-claimed.
Regulatory treatment of AOD-9604 has varied. In sports anti-doping, the peptide became widely discussed during a 2013 investigation into an Australian professional sports club. Authorities at the time debated whether it fell under prohibitions on growth hormone and related substances. Later clarifications and updated lists have addressed the compound in different ways. Anyone seeking current status should consult the latest applicable rules, and commercial supply for human use is not authorized in major markets.
Research interest in AOD-9604 often focuses on whether it can influence lipid metabolism without the growth-promoting or glucose-related effects of full-length hGH. This question remains unresolved, and findings depend on model, dose, and measurement method. Some reviews treat the peptide as a historical obesity candidate rather than an active therapeutic. Others cite it in discussions of peptide fragments, metabolic signaling, and performance-enhancing substances. Clear conclusions are limited by the small number of rigorous, independent human studies.
In the scientific literature, AOD-9604 appears in reviews of growth hormone fragments and in discussions of peptide-based metabolic research. Some sources distinguish it from growth hormone itself, while others group it with compounds marketed for weight management. The evidence base is small compared with approved obesity medications. Questions about long-term efficacy and clinical relevance remain open, and independent replication of key findings is limited. Most published reports are early-stage and exploratory.
AOD-9604 is a synthetic peptide modeled on the C-terminal region of human growth hormone. It is often described as hGH fragment 176-191. Research interest arose because it was designed to isolate possible effects on fat metabolism from other actions of growth hormone. It is not a full growth hormone molecule. Its development history includes early laboratory and animal studies followed by human trials. The peptide has been examined in laboratory, animal, and limited human studies.
The compound has been studied as a potential treatment for obesity and related metabolic conditions. Published trials have examined changes in body weight, fat mass, and safety markers over limited durations. Results have been mixed or modest, and no large-scale outcome trials are established. Regulatory agencies in several countries have not approved it as a therapeutic drug. Some commercial products have been marketed outside regulated pharmaceutical channels, which raises questions about quality and claims.

Research has examined whether the peptide affects fat mass independently of growth hormone's other actions. Early animal studies suggested reductions in body fat, but species differences and small sample sizes limit interpretation. Human studies have generally been short and have not consistently shown large effects. Some trials measured body composition, lipid profiles, and safety parameters, but the overall picture is one of suggestive yet inconclusive metabolic activity. Findings vary across study populations and protocols.
A central uncertainty is whether observed metabolic changes translate into meaningful clinical benefits. Study designs vary in dose, duration, and participant characteristics, making comparisons difficult. Independent replication is limited, and the field lacks consensus on optimal endpoints or treatment duration. Ongoing or future studies may clarify mechanism and effect size, but current evidence does not establish a clear therapeutic role. Researchers often call for larger, longer, and better-controlled trials, while questions remain about which patient groups might respond.
Clinical development of AOD9604 included trials in people with obesity, but the results did not lead to approval as a prescription medicine in major markets. Interest later shifted to research settings and to unapproved products marketed for body composition. Regulatory agencies have questioned whether the peptide qualifies as a dietary ingredient, and some have issued warnings about its presence in supplements. Long-term human safety data are limited, and questions about efficacy, dosing, and target populations remain unresolved.
AOD9604 is a synthetic peptide modeled on the C-terminal region of human growth hormone. It corresponds to a short sequence near the end of the 191-amino-acid hormone, often described as residues 176–191 or a related fragment. Researchers designed it to separate metabolic effects from the growth-promoting actions of full-length growth hormone. Early work in the 1990s explored it as a candidate for weight and lipid disorders. It is not a naturally circulating hormone fragment produced in large amounts.

Furthermore, sample processing for downstream mass spectrometry (MS) analysis is much more intensive than in NMR application, and results in the destruction of the original sample (via trypsin digestion). Following identification and quantification of metabolites in individual patient samples, NMR and mass spectrometry (MS) output is compiled into a dataset. These datasets include information on the identity and levels of individual metabolites detected within processed samples, as well as characteristics of each metabolite during the detection process (e.g. mass-to-charge ratios for mass spectrometry (MS)-based analysis). Multiple datasets can be created and compiled into large databases for individual patients in order to monitor varying metabolic profiles over a treatment course (i.e. pre- and post-treatment profiles). Each database is then processed through a type of informatics platform with software designed to characterize and analyze the data to generate an overall metabolic profile for the patient. To generate this overall profile, computational programs are designed to:
== Usage during original Cold War == The phrase "new Cold War" was first used in 1955 by US secretary of state John Foster Dulles, and in a 1956 New York Times article warning of Soviet propaganda promoting the Cold War's resurgence. Other analysts, such as academics Fred Halliday, Alan M. Wald, David S. Painter, and Noam Chomsky, used the interchangeable terms to refer to the 1979–1985 or 1985–1991 phases of the Cold War. Some other analysts used similar terms to refer to the Cold War of the mid-1970s. Columnist William Safire argued in a 1975 New York Times editorial that the Nixon administration's policy of détente with the Soviet Union had failed and that "Cold War II" was then underway. Academic Gordon H. Chang used the term "Cold War II" to refer to the Cold War period after the 1972 meeting in China between US president Richard Nixon and Chinese Communist Party chairman Mao Zedong.
=== Sweden === The Swedish Armed Forces use ration packs from the Swedish-developed 24 hour meals. 24 hour meals have a long range of menus (approx. 200) and can deliver both freezedried and wet meals. The Swedish concept (combat edition) consists of several versions for different use, in all climate zones, and various types of missions. Examples of different types of rations: 1-course (patrolration), 2-course, 3-course and 4-course versions with a variation of 40 different meals, both wet and dry. The rations varies from 1300 kcal to 5000 kcal. The ration is packed in a transparent durable plastic bag that is resealable with a ziplock. The contents are 1–4 main meals with energy bars, protein bars, nuts, energy drinks, whole wheat bread, peanut butter, desserts and spices for example. The durable bag change size depending on the version for optimal space usage in cartons and soldiers' backpacks. 24 hour meals have been developed at a rapid pace and are currently producing their 5th generation (first in 2008). R&D are working close with soldiers in Scandinavia and various missions around the world.
== Safety considerations == Inhalation of crystalline silica harms the lungs, causing silicosis. Amorphous silica is considered to have low toxicity, but prolonged inhalation causes lung changes. Diatomaceous earth is mainly amorphous silica but contains some crystalline silica, especially in the saltwater forms. In a 1978 study of workers, those exposed to natural diatomaceous earth for over five years had no significant lung changes while 40% of those exposed to the calcined form had developed pneumoconiosis. Today's standard diatomaceous earth formulations are safer to use, as they are predominantly made of amorphous silica and contain little or no crystalline silica. The crystalline silica content of diatomaceous earth is regulated in the United States by the Occupational Safety and Health Administration (OSHA). There are guidelines from the National Institute for Occupational Safety and Health that set maximum amounts allowable in the product (1%) and in the air near the breathing zone of workers, with a recommended exposure limit at 6 mg/m3 over an 8-hour workday. OSHA has set a permissible exposure limit for diatomaceous earth as 20 mppcf (80 mg/m3/%SiO2). At levels of 3,000 mg/m3, diatomaceous earth is immediately dangerous to life and health. In the 1930s, workers with long-term occupational exposure in the cristobalite diatomaceous earth industry who were exposed to high levels of airborne crystalline silica over decades were found to have an increased risk of silicosis.

However, results suggested that if the submaximal effort power was scaled to 80% of a subject's new, post-EPO treatment VO2max, the subjects would actually see a decrease in how long they could maintain their new, updated 80% effort. A 2017 study showed that at submaximal exertion, the effects of EPO were not distinguishable from a placebo. However, the 2017 study still showed that at maximal exertion, the EPO-treated group performed better than the placebo group. In March 2019, American mixed martial artist and former UFC Bantamweight Champion T.J. Dillashaw tested positive for EPO in a drug test administered by USADA, and was stripped of the UFC bantamweight title and suspended for two years. In September 2023 two-time tennis major champion Simona Halep received a 4-year suspension by the International Tennis Integrity Agency for two separate violations, one concerning the level of EPO in a blood sample collected in August 2022; Halep maintained her innocence, and indicated she would appeal the ban. Halep was later cleared to return following a successful appeal, due to findings that a contaminated supplement most likely contributed to the positive tests.
In accordance with its low DAT occupancy, no measurable dopamine release in the human brain was detected with bupropion (one 150 mg dose) in a PET study. Bupropion has also been shown to increase reuptake of dopamine by striatal VMAT2, though it is unknown if this effect is more pronounced than other DRIs. These findings raise questions about the role of dopamine reuptake inhibition in the pharmacology of bupropion, and suggest that other actions may be responsible for its therapeutic effects. No data are available on occupancy of the norepinephrine transporter (NET) by bupropion and its metabolites. However, due to the increased exposure of hydroxybupropion over bupropion itself, which has higher affinity for the NET than the DAT, bupropion's overall pharmacological profile in humans may end up making it effectively more of a norepinephrine reuptake inhibitor (NRI) than a dopamine reuptake inhibitor. Accordingly, the clinical effects of bupropion are more consistent with noradrenergic activity than with dopaminergic actions. However, in contrast to other NRIs like atomoxetine and reboxetine, but similarly to methylphenidate, bupropion fails to alter the clinical tyramine pressor response, an index of norepinephrine reuptake inhibition.
=== Greenlandic === The longest word in Greenlandic is Nalunaarasuartaateeraaranngualioqatigiiffissualioriataallaqqissupilorujussuanngortartuinnakasinngortinniamisaalinnguatsiaraluallaqqooqigaminngamiaasiinngooq, which has 156 letters. The rough translation of this word is: "There were reports that they apparently – God knows for how many times – once again had considered whatever I, my poor condition despite, still could be considered to be quite adept and resourceful as initiator to put a consortium together for the establishment of a range of tiny radio stations." The word is a tongue twister that forms an entire sentence, rather than being a word or phrase commonly heard in Greenland. Inuussutissarsiorsinnaajunnaarnersiutilik, consisting of 41 letters, is the longest singular word in the Greenlandic dictionary.

== History == The disease is named after Joannes Cassianus Pompe, who characterized it in 1932. Pompe described the accumulation of glycogen in muscle tissue in some cases of a previously unknown disorder. This accumulation was difficult to explain as the enzymes involved in the usual metabolism of glucose and glycogen were all present and functioning. The basis for the disease remained a puzzle until Christian de Duve's discovery of lysosomes in 1955 for which he won the Nobel Prize in 1974. His co-worker Henri G. Hers realised in 1965 that the deficiency of a lysosomal enzyme (alpha-glucosidase) for the breakdown of glycogen could explain the symptoms of Pompe disease. This discovery led to establishing the concept of lysosomal storage diseases, of which 49 have been described (to date). Despite recognizing the basis for the disease, treatment proved difficult. Administration of the enzyme leads to its uptake by the liver and not the muscle cells where it is needed. In the early 1990s Dutch scientists Arnold Reuser and Ans van der Ploeg were able to show that using alpha-glucosidase containing phosphorylated mannose residues purified from bovine testes increased the enzyme's activity in normal mouse muscles. Later in 1998, Yuan-Tsong Chen and colleagues at Duke University, using the enzyme produced in Chinese hamster ovary (CHO) cells demonstrated for the first time that the enzyme can clear the glycogen and improve muscle function in Pompe disease quail.
From July 1, 2025, through the March 3, 2026 primary, $120,721.54 in itemized receipts attributed to Rourk's campaign were identified in Federal Election Commission records, including $26,435.29 in contributions from Rourk herself. Of the remaining $94,286.25 in itemized contributions from other individuals, $75,521.25 (80.1%) came from contributors outside the district, including $47,436.25 from outside Texas and $28,085 from Texas contributors outside the district. In-district contributors accounted for $18,765 of those individual contributions.
== Cause == This disorder is caused by a mutation in a gene, TANGO2, which codes for protein Transport and golgi organization 2 homolog, and its located on chromosome 22. According to one study, exons 3-9 are frequently deleted in people of European origin and Hispanic ethnicity, although in Hispanic ethnicity c.460G>A (which is expressed as p.Gly154Arg, which means that on position 154, glycine is changed to arginine) is also frequent. Also, people with 22q11.2DS (DiGeorge syndrome) are at risk of developing this disorder because of hemizygosity (which means that they express only one copy of that gene, consequently chances of getting this disorder is higher).
=== Availability === Cyclofenil remains available today only in Brazil, Italy, and Japan. In the past, it has also been available in France, Germany, Mexico, Sweden, Switzerland, Turkey, and the United Kingdom.
== Net worth == In October 2017, Forbes listed Newell among the 100 wealthiest people in the United States, with an estimated net worth of $5.5 billion. In December 2021, Forbes estimated that Newell had a net worth of $3.9 billion and owned at least one quarter of Valve. According to Charlie Fish, the author of The History of Video Games, as of 2021 Newell was the richest person in the video game industry. In 2025, Forbes estimated that Newell owned at least half of Valve and had a net worth of $11 billion.

No major medicines regulator appears to have approved AOD-9604 for human therapeutic use. It has been studied in clinical trials, but those programs did not result in a marketed drug.
It became prominent during a 2013 Australian sports investigation that examined whether it was a prohibited growth-hormone-related substance. Subsequent interpretations and list updates have varied, so current rules should be checked directly.
Published summaries generally report limited or inconsistent weight-loss effects, and complete trial data are not widely available. The studies were not sufficient to establish it as an effective obesity treatment.
It is a synthetic peptide fragment derived from the C-terminal region of human growth hormone, commonly referred to as hGH fragment 176-191. It has been investigated for effects on fat metabolism, but it is not an approved medication in most jurisdictions.
