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 2026-01-22. Where a claim depends on a specific study, the study is described rather than over-claimed.
AOD-9604 has been investigated primarily as a potential treatment for obesity and related metabolic conditions. Early laboratory work examined its effects on fat cells, and later studies moved into animal models and human clinical trials. Some trials reportedly reached Phase II, but the program did not lead to an approved medicine. Published summaries often note that weight-loss results were modest or inconsistent. The full trial data are not all publicly available in detail.
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.
The peptide is frequently described as a growth hormone fragment, although it is chemically distinct from full-length hGH. AOD-9604 contains 16 amino acids and includes two cysteine residues that can form an intramolecular disulfide bond. In solution, this structural feature can influence folding, aggregation, and stability. Published descriptions sometimes call it hGH 176-191 or AOD9604, with spacing and capitalization varying. Such naming differences can complicate literature searches, database entries, and product verification.
Researchers have studied the fragment in cell and animal models to understand its metabolic actions. Some experiments report effects on fat breakdown and fat storage pathways, but the underlying mechanism remains incompletely defined. AOD-9604 does not appear to stimulate the same broad growth hormone receptor signaling as full-length hGH. Whether its observed activities arise from direct receptor interactions or downstream metabolic changes is an open question. Results from different assays are not always consistent.
AOD-9604 is a synthetic peptide modeled on the C-terminal region of human growth hormone. It corresponds to residues 176-191 of the 191-amino-acid hGH sequence. The fragment is not the full hormone and lacks the receptor-binding region associated with growth and metabolic effects of hGH. Researchers developed it to isolate a specific portion of hGH for study. Its exact sequence and length are often stated in peptide catalogs and patents.

Commercial AOD-9604 may vary in purity, counterion content, and residual moisture. Certificates of analysis often report HPLC purity, mass confirmation, and appearance, but testing methods differ between suppliers. Independent verification is sometimes used because labeled content may not match actual peptide amount. Stability under different pH and temperature conditions is not fully standardized across studies. Researchers generally treat lyophilized material as the reference form for weighing and reconstitution. Moisture content can affect accurate mass measurement.
AOD-9604 is typically supplied as a lyophilized white to off-white powder. In this form, it is relatively stable when kept cool, dry, and protected from light. Common storage recommendations place it at −20 °C or below for long-term retention. Reconstituted solutions are less stable and are often kept at 2–8 °C for short periods. Freeze-thaw cycles should be minimized because they can promote aggregation or loss of peptide content. Vials are usually sealed under inert gas to reduce oxidation.
Identity and purity are commonly checked with reversed-phase high-performance liquid chromatography and mass spectrometry. RP-HPLC separates the peptide from related impurities and can estimate purity by peak area. Mass spectrometry confirms molecular mass and helps detect sequence variants or truncations. Some laboratories use amino acid analysis or peptide mapping for additional characterization. No single method proves biological activity; these techniques establish chemical identity and purity only. They also require suitable reference standards for confident comparison.
AOD-9604 drew attention in the 1990s and 2000s as a potential anti-obesity agent. Early work explored both injectable and oral routes, which is unusual for a peptide of this size. Animal studies reported changes in fat metabolism without the growth-promoting or insulin-like effects associated with full-length growth hormone. Subsequent human trials produced mixed or modest results, and the compound did not obtain regulatory approval for weight management in major markets. It remains known mainly through research literature, sports anti-doping listings, and non-approved supplement advertising.
AOD-9604 is prohibited in sport by the World Anti-Doping Agency under the peptide hormone class. Its presence in a sample can be detected through mass spectrometry-based methods, although the exact assay depends on the laboratory. In research settings, material is often supplied as a lyophilized powder for reconstitution. Buyers and researchers should note that products labeled AOD-9604 may vary in purity and actual peptide content. Analytical certificates and independent testing are common ways to verify identity, but no global harmonized standard exists for all commercial lots.
Stability was somewhat restored during the reign of Theophilos (r. 829–842). He capitalised on economic growth to complete construction programmes, including rebuilding the sea walls of Constantinople, overhaul provincial governance, and wage inconclusive campaigns against the Abbasids. After his death, his empress Theodora, ruling on behalf of her son Michael III, permanently restored the veneration of icons; the empire prospered under their sometimes-fraught rule. Michael was posthumously vilified by historians loyal to the dynasty of his successor Basil I, who had him assassinated in 867 and later benefited from successes begun under his predecessor.
Conflicting theories explain saffron's arrival in South Asia. Kashmiri and Chinese accounts date its arrival anywhere between 2500 and 900 years ago. Historians studying ancient Persian records date the arrival to sometime prior to 500 BC, attributing it to a Persian transplantation of saffron corms to stock new gardens and parks. Phoenicians then marketed Kashmiri saffron as a dye and a treatment for melancholy. Its use in foods and dyes subsequently spread throughout South Asia. Buddhist monks wear saffron-coloured robes; however, the robes are not dyed with costly saffron but turmeric, a less expensive dye, or jackfruit. Monks' robes are dyed the same colour to show equality with each other, and turmeric or ochre were the cheapest, most readily available dyes. Gamboge is also used to dye the robes.
=== Reports from investigative journalists === In 2003, a German investigative journalist sponsored by the British Union for the Abolition of Vivisection (BUAV) filmed 40 hours of undercover footage at the company's primate-testing facility in Münster. Two films were produced, which were shown on German public television in December 2003. The footage showed animal keepers dancing with half-anaesthetized monkeys, making their heads move to the rhythm of the music. It also showed rough treatment of the monkeys by the staff. The monkeys were seen living isolated in small wire cages with little or no natural light and no environmental enrichment, with high noise levels caused by staff shouting and playing the radio, and undergoing surgery with no post-operative care. In response, the company maintained that clips showing different technicians working in different buildings had been edited together, resulting in a sequence of events that did not take place. The company also said there was group housing and pair housing for some monkeys that was not shown. In the films, the treatment of the monkeys was criticized by Jane Goodall. The environment minister for North Rhine-Westphalia asked the public prosecutor to investigate, and said that if the allegations were borne out, the company would lose its licence to keep primates. The company gained an injunction against the video. From April 2004 to March 2005, an undercover technician, sponsored by People for the Ethical Treatment of Animals (PETA), filmed the treatment of monkeys in the company's lab in Vienna, Virginia.
Indirect discrimination is often structural, and this is seen in the gender pay gap of 21.7% across the Australian workforce, meaning women employees earn on average 78.3 cents compared to each $1 for male employees, according to the annual employer census. The main reasons for the gender pay gap are sex discrimination in child care and parental leave laws based on "persistent cultural norms that see women as more likely to undertake primary carer duties for children and family", "outright gender-based discrimination at work", "patterns of workforce engagement" and occupational segregation. Under the Fair Work Act 2009 section 302, employees, unions and the Sex Discrimination Commissioner can make an equal pay claim. The first post-2009 cases were brought by unions for social and community service workers, supported by the government. The Fair Work Commission interprets the appropriate comparator narrowly. Before 2009, the Librarians case, librarians were awarded a pay increase since the skill and education levels were comparable to better paid male-dominated industries. Structural discrimination also underlies much of the race pay gap in Australia. The first time Indigenous employees became legally entitled to equal pay with white workers, in cattle and farming jobs, was through a decision in 1966. The exclusion in the Conciliation and Arbitration Act 1904 section 4 for "persons engaged in domestic service" meant that many Indigenous women and girls employed as domestic staff were excluded.

The previous election in 2023 saw a shift towards progressive parties, with the Move Forward Party winning 151 seats followed by the Thaksin Shinawatra-aligned Pheu Thai Party. The governing coalition of conservative parties only won 15% of the seats, with the Bhumjaithai Party being the only one to increase their numbers. Move Forward initially formed an eight party coalition with Pheu Thai, Thai Sang Thai, Prachachat, Thai Liberal, New Social Power, Thai Ruam Palang and the Fair Party. The coalition had a total of 313 MPs, giving them a majority in the House of Representatives. However, under the transitory provisions of the 2017 constitution, the prime minister was to be chosen by both elected MPs and NCPO-appointed Senators. As such, Move Forward leader Pita Limjaroenrat failed to gain enough votes to become prime minister. The opportunity to form government passed to Pheu Thai who formed a coalition excluding Move Forward that included conservative parties such as Bhumjaithai, and the military-backed Palang Pracharath and United Thai Nation parties. Their candidate, Srettha Thavisin, was elected prime minister on 22 August with the support of most Senators. The 2026 election was the third election under the 2017 constitution, which was implemented under Prime Minister Prayut Chan-o-cha and the National Council for Peace and Order (NCPO) and the first after the expiration of the constitution's five-year transitory provision that gave the Senate voting rights to choose the prime minister in a joint session of parliament.
== Decay == Uranium-238 is an alpha emitter, producing thorium-234 which is a beta emitter, etc. This leads to a decay chain, commonly called the radium series or uranium series. Beginning with naturally occurring uranium-238, this series includes isotopes of astatine, bismuth, lead, polonium, protactinium, radium, radon, thallium, thorium and uranium, all of which are present in natural uranium sources. The decay proceeds as (only main decay branches shown):
== Adverse effects == Safety and dosing trials showed that the incidence of adverse events in orforglipron-treated participants was 62–89%, mostly from gastrointestinal discomfort (44–70% with orforglipron, 18% with placebo); in patients experiencing adverse events, 96% had mild to moderate GI side effects, while approximately 4% had severe nausea or vomiting. The most common side effects of orforglipon noted in clinical trials were vomiting, diarrhea, nausea, upset stomach, and constipation.
In the early 1960s, Dayhoff also collaborated with Ellis Lippincott and Carl Sagan to develop thermodynamic models of cosmo-chemical systems, including prebiological planetary atmospheres. She developed a computer program that could calculate equilibrium concentrations of the gases in a planetary atmosphere, enabling the study of the atmospheres of Venus, Jupiter, and Mars, in addition to the present day atmosphere and the primordial terrestrial atmosphere. Using this program, she considered whether the primordial atmosphere had the conditions necessary to generate life. Although she found that numerous small biologically important compounds can appear with no special nonequilibrium mechanism to explain their presence, there were compounds necessary to life that were scarce in the equilibrium model (such as ribose, adenine, and cytosine). Dayhoff also taught physiology and biophysics at Georgetown University Medical Center for 13 years, served as a Fellow of the American Association for the Advancement of Science and was elected councillor of the International Society for the Study of the Origins of Life in 1980 after 8 years of membership. Dayhoff also served on the editorial boards of three journals: DNA, Journal of Molecular Evolution and Computers in Biology and Medicine.

C6H12O6 → 2 CO2 + 2 CH3CH2OH All aerobic organisms produce CO2 when they oxidize carbohydrates, fatty acids, and proteins. The large number of reactions involved are exceedingly complex and not described easily. Refer to cellular respiration, anaerobic respiration and photosynthesis. The equation for the respiration of glucose and other monosaccharides is:
Because women diagnosed with Gestational Diabetes (GDM) during pregnancy are at an increased risk for developing Type 2 Diabetes Mellitus after pregnancy, post-pregnancy glucose tolerance testing is needed. Based on the recent meta-analysis conducted by the Patient-Centered Outcomes Research Institute, research has shown that post pregnancy testing reminders are associated with greater adherence to oral glucose tolerance testing up to 1 year postpartum.
=== 2010–2012: Early career === Melksham was recruited by the Essendon Football Club with their first selection and tenth overall in the 2009 national draft. The Age journalist, Will Brodie, predicted he would debut and play in the midfield early in the season and he made his debut in the twenty point win against Carlton at the Melbourne Cricket Ground in round three. He played the next two matches before he was omitted for the round six match against Hawthorn at the Melbourne Cricket Ground; he returned the next week for the three-point loss against Port Adelaide at Etihad Stadium where he kicked his first AFL goal. He was rewarded with the round eight nomination in the AFL Rising Star after he recorded fourteen possessions, three clearances, three tackles and a goal in the twelve point win against St Kilda at Etihad Stadium. He missed the round ten match against the Western Bulldogs after he sprained his ankle during the thirty-five-point win against Richmond the week before, he returned the next week for the nine-point loss against Sydney at the Sydney Cricket Ground. He played the next four out of five matches, missing the round fifteen match against Melbourne due to being rested, before he was dropped for the round seventeen match against North Melbourne at Etihad Stadium.
== Overdose == Overdose of minoxidil has been reviewed. In 2013 or 2014, a seven-year-old girl was admitted to a children's hospital in Toulouse in France after accidentally ingesting a teaspoon of Alopexy (a brand name for minoxidil in France). The child vomited constantly after ingestion and showed hypotension and tachycardia for 40 hours. The authors of the report on the incident stressed that the product should be kept out of reach of children, and urged manufacturers to consider more secure child-resistant packaging.

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.
No, it is a synthetic peptide fragment corresponding to a small portion of hGH. It is not the full 191-amino-acid hormone and does not reproduce all of hGH's effects.
