This is a working overview of AOD-9604, written for readers who want more than a one-paragraph summary but less than a textbook.
This page was last updated on 2026-04-03 and is reviewed periodically as new material appears.
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.
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.
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.

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.
Proposed mechanism focuses on lipolysis, the breakdown of stored triglycerides into free fatty acids and glycerol. AOD-9604 is thought to act on adipose tissue without stimulating appetite or affecting blood sugar in the same way as growth hormone. Laboratory studies report increased fat oxidation in some models. The precise receptor interactions and signaling pathways remain incompletely characterized. Researchers have proposed that the peptide may influence fat mobilization through pathways distinct from the full hormone.
Detection and characterization of AOD-9604 in research and anti-doping settings typically rely on mass spectrometry coupled with liquid chromatography. These methods can identify the peptide by its mass and fragmentation pattern. Immunoassays may also be used in some screening contexts, but they can cross-react with related peptides. Because the molecule is small and may be present at low concentrations, sample preparation and method validation are important. Confirmatory analysis usually requires comparison with a certified reference standard.
In laboratory settings, AOD-9604 is commonly supplied as a lyophilized powder and stored cold to limit degradation. Reconstituted solutions are typically kept refrigerated or frozen, depending on the buffer and concentration, and protected from repeated freeze-thaw cycles. Stability can be influenced by pH, temperature, and the presence of proteases. Purity is usually assessed by high-performance liquid chromatography and mass spectrometry. These practices support reproducibility, but they do not imply safety or efficacy for any human use.
==== South Ossetian attacks and Georgian response ==== The commission said that a government "is generally not prevented" to use armed force against opposing side in internal conflicts, such as rebels or violent secessionists. However, the report said that Georgia had a non-use of force commitment under the international legal documents, such as the 1992 Sochi Agreement and 1996 Memorandum on Measures to Provide Security and Strengthen Mutual Trust between the Sides in the Georgian-South Ossetian Conflict. The commission said that the South Ossetian attacks on Georgian villages (Zemo Nikozi, Kvemo Nikozi, Avnevi, Nuli, Ergneti, Eredvi and Zemo Prisi) equaled to an "attack by the armed forces of a State on the territory of another State" similar to the situations described in Art. 3(a) of UN Resolution 3314. Since the South Ossetian attacks mainly targeted Georgian peacekeepers and Georgian police, this was "an attack by the armed forces of South Ossetia on the land forces of Georgia". The commission found out that several residents of the assaulted villages became casualties in "the acts preceding the outbreak of the hostilities" and "From 6 August on, continuous heavy fighting took place." The commission could not prove that Russian peacekeepers took part in the attacks on Georgian villages, but noted that "Such attacks were rather initiated by the South Ossetian militia." The commission also said "South Ossetia violated the prohibition of the use of force" as long as South Ossetia had attacked the Georgian villages.

== Adverse effects == Common adverse effects are constipation and nausea, but rates of discontinuation due to constipation were low for both eluxadoline and placebo. Rare adverse effects: fatigue, bronchitis, viral gastroenteritis. Rare serious adverse effects include pancreatitis with a general incidence of 0.3%: higher incidence with 100 mg dose (0.3%) than with 75 mg dose (0.2%). The risk is even greater in those who do not have a gallbladder and the medication is not recommended in this group. In March 2017, the U.S. Food and Drug Administration issued a safety alert for eluxadoline concerning an increased risk of serious pancreatitis in patients without a gallbladder. An FDA review found that in such patients, spasm of the sphincter of Oddi may lead to severe pancreatitis. The FDA reported that in some cases symptoms have occurred with just one or two doses at the recommended dosage for patients without a gallbladder (75 mg). Of two deaths associated with eluxadoline reported up to February 2017, both occurred in patients without a gallbladder.

In mammals, this metabolic pathway is important in beta oxidation of fatty acids and catabolism of amino acids and choline, as it accepts electrons from multiple acetyl-CoA dehydrogenases. In plants, ETF-Q oxidoreductase is also important in the metabolic responses that allow survival in extended periods of darkness.
Towards the end of this period the pro-independence forces made two important advances. In the Southern Cone, a veteran of the Spanish army with experience in the Peninsular War, José de San Martín, became the governor of the Province of Cuyo. He used this position to begin organizing an army as early as 1814 in preparation for an invasion of Chile. This was an important change in strategy after three United Provinces campaigns had been defeated in Upper Peru. San Martín's army became the nucleus of the Army of the Andes, which received crucial political and material support in 1816 when Juan Martín de Pueyrredón became Supreme Director of the United Provinces. In January 1817, San Martín was finally ready to advance against the royalists in Chile. Ignoring an injunction from the congress of the Río de la Plata not to move against Chile, San Martín together with General Bernardo O'Higgins Riquelme, later Supreme Director of Chile, led the Army over the Andes in a move that turned the tables on the royalists. By 10 February, San Martín had control of northern and central Chile, and a year later, after a war with no quarter, the south. With the aid of a fleet under the command of former British naval officer Thomas Cochrane, Chile was secured from royalist control and independence was declared that year. San Martín and his allies spent the next two years planning an invasion of Peru, which began in 1820.
Some of the earliest ancient human civilisations in South Asia originated from areas encompassing present-day Pakistan. The earliest known stone tools in the region, dating to the Lower Palaeolithic (~2 million years ago), were discovered in the Soan Valley of northern Pakistan. The Indus plain region, which covers most of the present-day Pakistan, was the site of several successive ancient cultures including the Neolithic (7000–4300 BCE) site of Mehrgarh, and the 5,000-year history of urban life in South Asia to the various sites of the Indus Valley Civilisation, including Mohenjo-daro and Harappa. Following the decline of the Indus Valley Civilisation, semi-nomadic Indo-European Aryans migrated into the Indian subcontinent around 2000 BCE, perhaps by way of the Khyber Pass. They fused with the indigenous Harappan culture of the Indus Valley, and elements of the pre-Aryan spiritual traditions were assimilated into the developing Vedic tradition. This cultural milieu shaped the Gandhara Civilisation, which flourished at the crossroads of India, Central Asia, and the Middle East, connecting trade routes and absorbing cultural influences from diverse civilisations. By the early Vedic period, parts of the Indus region in present-day Pakistan were populated by numerous tribes that were beginning to coalesce into chieftain-led clans and early kingdoms. During this period, the Vedas, the oldest scriptures of Hinduism, were composed.

=== American Indian === Alaska Native Brotherhood Brotherhood of North American Indians - Founded by Richard C. Adams of the Delaware Tribe of Oklahoma on December 5, 1911, in Washington, DC. Membership was open to people of Indian blood. Those married to Indians, the President of the United States, the Commissioner of Indian Affairs, and other public officials could become honorary members, without vote. The Brotherhood advocated giving Indians the right to vote and granting them citizenship, the placement of Indian children in public school, more Indians working at the Bureau of Indian Affairs, and Indian representation in Congress. The national convention in Washington would elect 20 national chiefs, a Great Sachem, a Chief Historian, and a Great Chaplain. The Brotherhood collapsed in 1913. Daughters of Sacajawea - Organized in the 1920s, possibly as the New York City chapter of the Teepee Order of America. Both groups were founded by Red Fox Francis St. James, which created difficulties, as he was intolerant of Catholics and blacks, so Catholic Indians and those that had black ancestry opposed his groups. In 1926, Princess Chinquilla, a Cheyenne woman, was the "Great Sacajawea" of the group and worked with St. James to create an Indian cultural center in New York, but the project fell through. Loyal Order of Tecumseh - Founded by Arthur C. Parker as a society within the Society of American Indians to provide a common ground for those with greater and lesser degrees of Indian blood.
== Scope == Medical genetics encompasses many different areas, including clinical practice of physicians, genetic counselors, and nutritionists, clinical diagnostic laboratory activities, and research into the causes and inheritance of genetic disorders. Examples of conditions that fall within the scope of medical genetics include birth defects and dysmorphology, intellectual disabilities, autism, mitochondrial disorders, skeletal dysplasia, connective tissue disorders, cancer genetics, and prenatal diagnosis. Medical genetics is increasingly becoming relevant to many common diseases. Overlaps with other medical specialties are beginning to emerge, as recent advances in genetics are revealing etiologies for morphologic, endocrine, cardiovascular, pulmonary, ophthalmologist, renal, psychiatric, and dermatologic conditions. The medical genetics community is increasingly involved with individuals who have undertaken elective genetic and genomic testing.
In the field of stable isotope geochemistry, isotopologues of simple molecules containing rare heavy isotopes of carbon, oxygen, hydrogen, nitrogen, and sulfur are used to trace equilibrium and kinetic processes in natural environments and in Earth's past.
A banana bag (or rally pack) is a bag of IV fluids containing vitamins and minerals. The bags typically contain thiamine, folic acid, and magnesium sulfate, and are usually used to correct nutritional deficiencies or electrolyte imbalances in the human body. The solution has a yellow color, hence the term "banana bag".

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.
No. It represents only a short portion of the hGH sequence and lacks the full hormone's structure. As a result, its biological activity and regulatory status differ from those of prescription hGH.
The exact peptide is not typically described as a circulating hormone; it is a synthetic construct based on a natural sequence. Fragments of hGH can exist in laboratory or metabolic contexts, but AOD-9604 itself is manufactured for research.
No. It is a synthetic peptide fragment modeled on part of human growth hormone, not the full hormone. It does not contain the complete sequence or receptor-binding regions of hGH.
