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.
AOD-9604 is a synthetic peptide whose structure corresponds to a C-terminal segment of human growth hormone. It is often described as hGH fragment 176-191, a 16-amino-acid sequence. The peptide was designed to isolate a region of hGH associated with fat metabolism while avoiding the full hormone's growth-promoting actions. Laboratory and commercial materials typically present it as a lyophilized powder for research use. Its identity is defined by amino acid sequence, not by a single brand.
The fragment includes residues that can form an internal disulfide bond between two cysteine positions. This structural feature can influence how the peptide folds and how stable it is in solution. AOD-9604 differs from full-length hGH in size and receptor interactions; it does not contain the entire growth hormone sequence. Published descriptions sometimes use slightly different residue numbering, so sequence information should be checked against primary sources. The molecule is small compared with intact hGH, which affects analytical detection and purification approaches.
Interest in AOD-9604 arose from attempts to separate metabolic effects from growth effects attributed to hGH. Early work explored whether the fragment could influence lipolysis or fat oxidation without promoting growth. Those questions remain partly unresolved because human data are limited and results have varied across studies. The peptide is not a hormone replacement for hGH and is not equivalent to hGH in clinical use. Its research history includes both laboratory studies and commercial marketing claims that are not the same as regulatory approval.

== History == The drug was invented by Ciba-Geigy (now Novartis) in the early 1980s and sold to Jenner Biotherapies in the 1990s. In 2003, IDM Pharma bought the rights and developed it further. IDM Pharma was acquired by Takeda along with mifamurtide in June 2009. Mifamurtide had already been granted orphan drug status by the U.S. Food and Drug Administration (FDA) in 2001, and the European Medicines Agency (EMA) followed in 2004. It was approved in the 27 European Union member states plus Iceland, Liechtenstein, and Norway by a centralized marketing authorization in March 2009. The drug was denied approval by the FDA in 2007. Mifamurtide has been licensed by the EMA since March, 2009.

== Early life == Dorian Andrew Mientjez Yates was born in Solihull on 19 April 1962. He grew up on a farm in nearby Hurley. When he was 13, his father died of a heart attack, after which he moved with his mother and sister to Walmley. He later lived in the Landywood and Castle Vale areas of Birmingham during his early professional bodybuilding years.

Transfer ribonucleic acid (tRNA), formerly referred to as soluble ribonucleic acid (sRNA), is an adaptor molecule composed of RNA, typically 76 to 90 nucleotides in length (in eukaryotes). In a cell, it provides the physical link between the genetic code in messenger RNA (mRNA) and the amino acid sequence of proteins, carrying the correct sequence of amino acids to be combined by the protein-synthesizing machinery, the ribosome. Each three-nucleotide codon in mRNA is complemented by a three-nucleotide anticodon in tRNA. As such, tRNAs are a necessary component of translation, the biological synthesis of new proteins in accordance with the genetic code.
=== Exercise === Exercise has been shown to improve insulin sensitivity in humans with metabolic syndrome. Increased exercise is therefore recommended in horses with EMS, assuming laminitis does not restrict activity levels. Current recommendations include 2–3 sessions a week, of 20–30 minutes of work, with gradual increase in duration and intensity.

President of League of Communists of Serbia Slobodan Milošević visited Kosovo in April 1987 and promised rapid action in order to protect peace and the Serbs of Kosovo. Ethnic tensions in Kosovo heated up when a Kosovo Albanian soldier opened fire on his fellow soldiers in Paraćin, in an event known as the Paraćin massacre. Then President of Serbia Ivan Stambolić wanted to make compromise, rather than fast solution. He found himself in a clash with Milošević. This conflict culminated with 8th Session and replacement of Stambolić with Petar Gračanin as President of Serbia.
== Dietary sources == Apart from animal livers, the richest dietary source of menaquinones are fermented foods (from bacteria, not molds or yeasts); sources include cheeses consumed in Western diets (e.g., containing MK-9, MK-10, and MK-11) and fermented soybean products (e.g., in traditional nattō consumed in Japan, containing MK-7 and MK-8). (Here and following it is noteworthy that most food assays measure only fully unsaturated menaquinones.) MK-4 is synthesized by animal tissues and is found in meat, eggs, and dairy products. Cheeses have been found to contain MK-8 at 10–20 μg per 100 g and MK-9 at 35–55 μg per 100 g. In one report, no substantial differences in MK-4 levels were observed between wild game, free-range animals, and factory farm animals. In addition to its animal origins, menaquinones are synthesized by bacteria during fermentation and so, as stated, are found in most fermented cheese and soybean products. As of 2001, the richest known source of natural K2 was nattō fermented using the nattō strain of Bacillus subtilis, which is reportedly a good source of long-chain MK-7. In nattō, MK-4 is absent as a form of vitamin K, and in cheeses it is present among the vitamins K only in low proportions. Still it is unknown whether B. subtilis will produce K2 using other legumes (e.g., chickpeas, or lentils) or even B. subtilis fermented oatmeal.
==== Answers to the investigation's problems ==== In the show Praça da Alegria, of RTP, the judge Rui Rangel was questioned about the thirteen years of investigation for a kidnapping accusation and the lack of its efficiency. The judge answered that the police is efficient, but that it "was needed that the Public Prosecution explains with clarity why it took thirteen years". When questioned by the press, the answer of the Attorney General of the Republic, Pinto Monteiro, was the following: "It probably couldn't take less time (...) I can't follow 550 thousand proceedings, especially one that started nine years before I became Attorney General (...) the investigators, better than anyone, will be able to say (...) the Prosecution doesn't have any comment to make".

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 based on a C-terminal fragment of human growth hormone. It is commonly referred to as hGH fragment 176-191 and is studied for metabolic effects rather than growth effects.
