The short version of AOD-9604 fits in a sentence. The long version — which is the one that helps — is below.
Reviewed 2026-01-01. Anything still debated is marked as such rather than presented as settled.
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.
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.

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.

Purity, more commonly referred to as black oil, and called the "black cancer" by the Russians, is an alien virus that thrived underground on Earth, in petroleum deposits. The virus is capable of entering humanoids and assuming control of their bodies. It has sentience and is capable of communicating. It was revealed to be the "life force" of the alien colonists, which they seemingly used to reproduce their kind, as well as infect other alien races in order to conquer the universe. The Syndicate in cooperation with the alien Colonists developed a delivery mechanism that would be used to introduce the virus into an unsuspecting public upon colonization. Africanized bees, extremely aggressive, that would sting indiscriminately, would carry the black oil virus through a transgenic corn crop specifically engineered to carry the virus and to attract the bees. The bees would be released on colonization and the infected human beings would become a slave race. The Syndicate, however, secretly tried to create a vaccine to protect themselves, which they code-named "Purity Control." While the Purity Control project ultimately fails, a rival Russian shadow group was successful in developing a weak vaccine that eventually fell into the hands of the Syndicate. The plot to cooperate with the alien colonization plan was implemented with the aim of being given access to the black oil for the transgenic corn, in order to perform experiments with it in an effort to develop a vaccine.
In addition to defence against predators, ants need to protect their colonies from pathogens. Secretions from the metapleural gland, unique to the ants, produce a complex range of chemicals including several with antibiotic properties. Some worker ants maintain the hygiene of the colony and their activities include undertaking or necrophoresis, the disposal of dead nest-mates. Oleic acid has been identified as the compound released from dead ants that triggers necrophoric behaviour in Atta mexicana while workers of Linepithema humile react to the absence of characteristic chemicals (dolichodial and iridomyrmecin) present on the cuticle of their living nest-mates to trigger similar behaviour. In Megaponera analis, injured ants are treated by nest-mates with secretions from their metapleural glands which protect them from infection. Camponotus ants do not have a metapleural gland and Camponotus maculatus as well as C. floridanus workers have been found to amputate the affected legs of nestmates when the femur is injured. A femur injury carries a greater risk of infection unlike a tibia injury. Nests may be protected from physical threats such as flooding and overheating by elaborate nest architecture. Workers of Cataulacus muticus, an arboreal species that lives in plant hollows, respond to flooding by drinking water inside the nest, and excreting it outside. Camponotus anderseni, which nests in the cavities of wood in mangrove habitats, deals with submergence under water by switching to anaerobic respiration.
During the Revolutions of 1848, the Austrian Chancellor Prince Klemens von Metternich resigned (March–April 1848). The young archduke was widely expected to soon succeed his uncle on the throne. While he was appointed Governor of Bohemia on 6 April 1848, he never took up the post. Sent instead to the front in Italy, he joined Field Marshal Radetzky on campaign on 29 April, receiving his baptism of fire on 5 May at Santa Lucia. By all accounts, he handled his first military experience calmly and with dignity. Around the same time, the imperial family fled revolutionary Vienna for the calmer setting of Innsbruck, in Tyrol. Called back from Italy, the archduke joined the rest of his family at Innsbruck by mid-June. It was here that Franz Joseph first met his cousin and future bride, Elisabeth, then a girl of 10, but apparently this meeting made little impression. Following Austria's victory over the Italians at Custoza in late July 1848, the court felt it safe to return to Vienna, and Franz Joseph travelled with them. But within a few weeks, Vienna again appeared unsafe, and in September, the court left once more, this time for Olmütz in Moravia. By now, Alfred I, Prince of Windisch-Grätz, an influential military commander in Bohemia, was determined to see the young archduke soon put on the throne. It was thought that a new ruler would not be bound by the oaths to respect constitutional government to which Ferdinand had been forced to agree, and that it was necessary to find a young, energetic emperor to replace the kindly but mentally unfit Ferdinand.

Incubation, which regulates temperature for chick development, usually begins after the last egg has been laid. In monogamous species incubation duties are often shared, whereas in polygamous species one parent is wholly responsible for incubation. Warmth from parents passes to the eggs through brood patches, areas of bare skin on the abdomen or breast of the incubating birds. Incubation can be an energetically demanding process; adult albatrosses, for instance, lose as much as 83 grams (2.9 oz) of body weight per day of incubation. The warmth for the incubation of the eggs of megapodes comes from the sun, decaying vegetation or volcanic sources. Incubation periods range from 10 days (in woodpeckers, cuckoos and passerine birds) to over 80 days (in albatrosses and kiwis). The diversity of characteristics of birds is great, sometimes even in closely related species. Several avian characteristics are compared in the table below.
Malaysia is the 66th largest country by total land area, with a total area of 330,803 km2 (127,724 sq mi). West Malaysia shares land borders with Thailand, while East Malaysia shares land borders with Indonesia and Brunei. Singapore is separated from the West by the Straits of Johor and is linked to it by a narrow causeway and a bridge. The country also shares maritime boundaries with Indonesia, Vietnam and the Philippines. The land borders are defined in large part by geological features such as the Perlis River, the Golok River and the Pagalayan Canal, whilst some of the maritime boundaries are the subject of ongoing contention. Brunei forms what is almost an enclave in Malaysia, with the state of Sarawak dividing it into two parts. Malaysia is the only country with territory on both the Asian mainland and the Malay Archipelago. The Strait of Malacca, lying between Sumatra and Peninsular Malaysia, is one of the most important thoroughfares in global commerce, carrying 40% of the world's trade. The southernmost point of mainland Asia is located at Tanjung Piai, in the state of Johor. The two parts of Malaysia, separated from each other by the South China Sea, share a largely similar landscape in that both Peninsular and East Malaysia feature coastal plains rising to hills and mountains. Peninsular Malaysia, containing 40% of Malaysia's land area, extends 740 km (460 mi) from north to south, and its maximum width is 322 km (200 mi).
== History == Medea was first performed in 431 BC at the City Dionysia festival. Here every year, three tragedians competed against each other, each writing a tetralogy of three tragedies and a satyr play (alongside Medea were Philoctetes, Dictys and the satyr play Theristai). In 431 the competition was among Euphorion (the son of famed playwright Aeschylus), Sophocles (Euripides's main rival) and Euripides. Euphorion won, and Euripides placed third (and last). Medea has survived the transplants of culture and time and continues to captivate audiences with its riveting power. The play's influence can be seen in the works of later playwrights, such as William Shakespeare. While Medea is considered one of the great plays of the Western canon, Euripides's place in the competition suggests that his first audience might not have responded so favorably. A scholium to line 264 of the play suggests that Medea's children were traditionally killed by the Corinthians after her escape; so Euripides's apparent invention of the filicide might have offended, as his first treatment of the Hippolytus myth did. That Euripides and others took liberties with Medea's story may be inferred from the 1st-century-BC historian Diodorus Siculus: "Speaking generally, it is because of the desire of the tragic poets for the marvellous that so varied and inconsistent an account of Medea has been given out." A common urban legend claimed that Euripides put the blame on Medea because the Corinthians had bribed him with a sum of five talents.
The IDF said that one in five rockets launched by Hezbollah had landed in Lebanese territory and published an infographic showing failed rocket launches into Israel. On 16 December, a soldier from the IDF's 129th Battalion was killed by a Hezbollah drone strike near Margaliot, which also caused a fire in a building. Two other soldiers were injured. Another drone was shot down by the IDF, which also responded to the infiltrations by shelling targets. The IAF later hit several Hezbollah targets inside Lebanon, including rocket launch sites and military infrastructure. On 22 December, two IDF soldiers of the 188th Armored Brigade were killed by a Hezbollah rocket attack in the Shtula area. On the morning of 23 December, IDF aircraft bombed a house in Kfar Kila and intense artillery fire also took place on the outskirts of Deir Mimas The IDF conducted a raid near a UNIFL center along the Khardali River. An Al-Manar cameraman was injured in the eye after an IDF attack on a road in the al-Khardali area where correspondents of MTV and the state-owned National News Agency were also passing. Hezbollah announced that two of their members were killed on that day. On 24 December, senior IRGC general Razi Mousavi was killed by an Israeli airstrike in Damascus. On 26 December, a Hezbollah anti-tank missile hit St. Mary's Greek Orthodox Church in Iqrit, northern Israel. A civilian suffered serious injuries, and when IDF responders arrived at the scene, another missile was fired, injuring nine soldiers.

=== Nuclear isomers, including a "stable" one === The 251 known stable nuclides include tantalum-180m, since even though its decay is automatically implied by it being "metastable", this has not been observed. All "stable" isotopes (stable by observation, not theory) are the ground states of nuclei, except for tantalum-180m, which is a nuclear isomer or excited state. The ground state, tantalum-180, is radioactive with half-life 8 hours; in contrast, the decay of the nuclear isomer is extremely strongly forbidden by spin-parity selection rules. It has been reported by direct observation that the half-life of 180mTa to gamma decay must be >1015 years. Other possible modes of 180mTa decay (beta decay, electron capture, and alpha decay) have also never been observed.
ATC code A10 Drugs used in diabetes is a therapeutic subgroup of the Anatomical Therapeutic Chemical Classification System, a system of alphanumeric codes developed by the World Health Organization (WHO) for the classification of drugs and other medical products. Subgroup A10 is part of the anatomical group A Alimentary tract and metabolism. Codes for veterinary use (ATCvet codes) can be created by placing the letter Q in front of the human ATC code: for example, QA10. National versions of the ATC classification may include additional codes not present in this list, which follows the WHO version.
This is a grave violation of the Constitution." Satarov claimed that Putin allowed Medvedev to make such mistakes, then later he would impeach Medvedev and hold a new presidential election. A former adviser to Putin, Andrey Illarionov, gave a speech at the Cato Institute in Ukraine on 4 September 2008, in which he refuted Russian propaganda claims - Russia was defending Russian citizens and was supporting Ossetian self-determination and that genocide was taking place in South Ossetia. Illarionov stated that before August 2008, Russian diplomats were spreading the word about Russian military operation in Georgia which would take place before September 2008. Illarionov noted that the restoration of the railway in Abkhazia "created the impression that the strike would be carried out from Abkhazia." Illarionov also noted, "Military analysts have calculated that considering the top speed of the ships, for them to have arrived in Poti on the 9th and 10th of August, they would have had to leave Sevastopol on the evening of August 7th". In September 2008, human rights activist Aleksandr Mnatsakanyan said that it was Russia and the regime of Eduard Kokoity who were preparing for the war. He said that he had viisted Tskhinvali a month before the war and saw the military preparations. Mnatsakanyan said that Georgia didn't commit any ethnic cleansing and genocide. He approved of the Georgian operation in Tskhinvali and said that most damage was not done to the residential areas.
== Validation or verification == The main difference between the two is that validation is focused on ensuring that the device meets the needs and requirements of its intended users and the intended use environment, whereas verification is focused on ensuring that the device meets its specified design requirements. For instance, a regulatory agency (such as CE or FDA) may ensure that a product has been validated for general use before approval. An individual laboratory that introduces such an approved medical device may then not need to perform their own validation, but generally still need to perform verification to ensure that the device works correctly.

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.
