AOD-9604 is one of those subjects where the details matter more than the headlines. This page pulls together the background, the mechanisms, and the practical points readers ask about most.
Last reviewed on 2025-12-02. 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.
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.
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.
Identity and purity are usually assessed with reversed-phase high-performance liquid chromatography and mass spectrometry. Reversed-phase HPLC separates the peptide from related impurities and can estimate purity by ultraviolet absorbance, while mass spectrometry confirms the molecular mass and detects modifications. Peptide mapping, amino acid analysis, and disulfide mapping may be used when the sequence or disulfide arrangement must be verified. Because AOD9604 contains cysteine residues, oxidation and disulfide isomers are possible quality concerns in synthetic batches.
Quality varies among research-grade suppliers, so certificates of analysis and independent testing are important for verification. A typical certificate reports purity by HPLC, identity by mass spectrometry, appearance, and sometimes residual solvents or water content. AOD9604 is often sold as a research chemical not intended for human consumption, and labels can be inaccurate. Common misconceptions include treating the peptide as a form of growth hormone, assuming supplement status, or expecting approved-drug quality from unregulated products.
== Signs and symptoms == The signs and symptoms of an infection depend on the type of disease. Some signs of infection affect the whole body generally, such as fatigue, loss of appetite, weight loss, fevers, night sweats, chills, aches and pains. Others are specific to individual body parts, such as skin rashes, coughing, or a runny nose. In certain cases, infectious diseases may be asymptomatic for much or even all of their course in a given host. In the latter case, the disease may only be defined as a "disease" (which by definition means an illness) in hosts who secondarily become ill after contact with an asymptomatic carrier. An infection is not synonymous with an infectious disease, as some infections do not cause illness in a host.
=== 23 May === In its evening report, the Ukrainian military reported that there were 25 air strikes and 20 incidents of shelling reported across the country for the day, but no missile attacks. Yevgeny Prigozhin, head of the Wagner Group, promised to transfer control of the Ukrainian city of Bakhmut to the Russian army by 1 June. In an interview, he said that more than 20,000 of his fighters died in the battle for the city, and acknowledged that the Russian military had killed civilians. President Zelenskyy visited naval infantry troops along the Vuhledar-Maryinka defence line in Donetsk Oblast as part of commemorations of the Day of the Ukrainian Marines. He announced that new marine brigades would be added to the Ukrainian military's existing units. The governor of Donetsk Oblast said Russian aerial bombs struck Toretsk, damaging a school but causing no casualties. The Russian Ministry of Defence said that it had forced back "nationalists" who had launched the cross-border attacks in Belgorod Oblast back into Ukraine, adding that its forces had killed more than 70 "Ukrainian terrorists" and destroyed four armored combat vehicles and five pickups. The Governor of Russia's Kursk Oblast said three villages bordering Ukraine were left without power after a drone dropped explosives on an electrical substation. Ukraine accused Russia of blocking access to the port of Pivdennyi to grain exports despite the resumption of the Black Sea Grain Initiative.
The 2002 study concluded that "the theory TT possesses is deprived of explanatory power" and "evidence that supports the current picture of physical energy should be regarded as evidence against the theory of TT". The supposed healing in TT takes place through a discredited physical process called "electron transfer resonance", which the physicist Alan Sokal describes as "nonsense."
== Early life, education and career == Moroder studied chemistry at the University of Padova, where he graduated 1965 in chemistry with the doctoral thesis on synthesis of S-peptide of ribonuclease A in the laboratory of Ernesto Scoffone at the Institute of Organic Chemistry. In 1968 he joined Klaus H. Hofmann's Group at the University of Pittsburgh to work on chemical synthesis of the peptidic adrenocorticotropic hormone and its derivatives. Moroder habilitated in 1971 at the University of Padova in Chemistry of Natural Products. 1975 he became a senior research fellow in the Department of Peptide Chemistry at the Max Planck Institute for Biochemistry (MPIB) in Martinsried headed by Erich Wünsch. Between 1991 and 2008 he was the head of the Laboratory of Bioorganic chemistry at the MPIB. Since 1994 he was an adjunct professor at the Technical University of Munich.
=== Health hazards === Honey is generally safe when taken in typical food amounts, but it may have various, potential adverse effects or interactions in combination with excessive consumption, existing disease conditions, or drugs. Included among these are mild reactions to high intake, such as anxiety, insomnia, or hyperactivity in about 10% of children, according to one study. No symptoms of anxiety, insomnia, or hyperactivity were detected with honey consumption compared to placebo, according to another study. Honey consumption may interact adversely with existing allergies, high blood sugar levels (as in diabetes), or anticoagulants used to control bleeding, among other clinical conditions. People who have a weakened immune system may be at risk of bacterial or fungal infection from eating honey.

=== Phytochemicals === Bilberries contain diverse polyphenols, including tannins, organic acids, phenolic acids, and anthocyanins, specifically anthocyanidins as delphinidin and cyanidin glycosides. V. myrtillus bilberry pulp is red or purple, and V. uliginosum bog bilberry pulp is pale-coloured. The high anthocyanin content of V. myrtillus may cause staining of the fingers, lips, and tongue. The anthocyanin content of bilberries and bilberry juice may exceed the levels seen in blueberries and blueberry juice.
has units of dose per body weight (g/kg) divided by concentration (g/L blood) - calculation gives values of 0.64 L/kg for men and 0.52 L/kg for women, lower than the original. Newer studies have updated these values to population-average ρv of 0.71 L/kg for men and 0.58 L/kg for women. But individual Vd values may vary significantly - the 95% range for ρv is 0.58-0.83 L/kg for males and 0.43-0.73 L/kg for females. A more accurate method for calculating Vd is to use total body water (TBW) - experiments have confirmed that alcohol distributes almost exactly in proportion to TBW within the Widmark model. TBW may be calculated using body composition analysis or estimated using anthropometric formulas based on age, height, and weight. Vd is then given by
== Description == This clade circumscribes five subordinate clades: two traditional tribes (Hypocalypteae and Indigofereae) and three informal clades (the mirbelioids, the millettioids, and Hologalegina), as well as several minor taxa. The name of this clade is informal and is not assumed to have any particular taxonomic rank like the names authorized by the ICBN or the ICPN. The clade does not currently have a node-based definition.
=== Influence of contact shape === Even in the presence of perfectly smooth surfaces, geometry can come into play in form of the macroscopic shape of the contacting region. When a rigid punch with flat but oddly shaped face is carefully pulled off its soft counterpart, its detachment occurs not instantaneously but detachment fronts start at pointed corners and travel inwards, until the final configuration is reached which for macroscopically isotropic shapes is almost circular. The main parameter determining the adhesive strength of flat contacts occurs to be the maximum linear size of the contact. The process of detachment can as observed experimentally can be seen in the film.

== Side effects == Common side effects are peeling, itching, redness, dryness, burning, and dermatitis. Benzoyl peroxide bleaches hair, clothes, towels, bedclothing, and the like. Prolonged exposure to natural or artificial sun light (UV rays) is not recommended because the gel may cause photosensitivity. Irritation due to benzoyl peroxide can be reduced by avoiding harsh facial cleansers and wearing sunscreen prior to sun exposure. Clinical studies have shown systemic absorption of clindamycin through topical application, in some cases leading to diarrhea, bloody diarrhea, and colitis. Reports of anaphylaxis were also seen. However, the sources of these reports were personal accounts without controls and of an unknown population, thus it is difficult to attribute their cause to the clindamycin/benzoyl peroxide gel.
== Function == DHX8 is localized in the cellular nucleus and stimulated upon RNA presence. This protein is a component of the spliceosome, so it takes part in pre-mRNA splicing. Splicing is the process of joining exons from primary transcripts of messenger RNA and the elimination of intron sequences, by means of a spliceosomal mechanism, so that the mRNA produced is the one without introns, consisting exclusively of the joined exons. Splicing finishes with the spliceosomal complex disassembly and the ATP-dependent liberation of the resulting mature RNAs to the outer of the nucleus. Spliceosome requires conformational changes to be able to catalyze splicing reactions and the later mature mRNA releasing to the outer of the nucleus. One of the ATP-dependent helicase needed for these conformational changes is DHX8. Furthermore, DHX8 plays a key role in the releasing, facilitating the nuclear export of spliced mRNA. Protein characterization has shown that DHX8 has a binding preference for adenine-rich RNA. This binding is followed by ATP hydrolysis and thus, ADP release.
In light of these events, Rush's record label tried to pressure the members into moulding their next album in a more commercially friendly and accessible fashion; the band ignored the requests and developed their next album 2112 (1976) with a 20-minute title track divided into seven sections. Despite that, the album was the Rush's first taste of significant commercial success as it reached No. 5 in Canada, becoming their first to reach double platinum certification. Rush toured in support of 2112 between February 1976 and June 1977 with concerts in Canada, the US, and for the first time Europe, with dates in the UK, Sweden, Germany, and the Netherlands. The three sold-out shows at Massey Hall in Toronto in June 1976 were recorded for Rush's debut live album, All the World's a Stage. Released in September of that year, the double album reached No. 6 in Canada and became Rush's first to crack the US top 40. Record World wrote: "Building its American reputation slowly but steadily Rush stands poised for breaking through all the way via this two record live set [...] All the highly charged electricity is here in an explosive setting." The liner notes include the statement, "This album to us, signifies the end of the beginning, a milestone to mark the close of chapter one, in the annals of Rush."
In Normandy, the 82nd gained its first Medal of Honor of the war, belonging to Private first class Charles N. DeGlopper of the 325th GIR. When the division was relieved in early July, the 82nd had seen a month straight of severe combat. Casualties were heavy. Losses included 5,245 troopers killed, wounded, or missing- a 46% casualty rate. Major General Ridgway's post-battle report stated in part, "... 33 days of action without relief, without replacements. Every mission accomplished. No ground gained was ever relinquished." Following Normandy, the 82nd Airborne Division returned to England to rest and refit for future airborne operations. The 82nd became part of the newly organized XVIII Airborne Corps, which consisted of the 17th, 82nd, and 101st Airborne Divisions. Ridgway was given command of the corps but was not officially promoted to lieutenant general until 1945. His recommendation for succession as division commander was Brigadier General James M. Gavin, previously the 82nd's assistant division commander. Upon being promoted to major general in October 1944 at the age of 37, Gavin became the youngest general since the Civil War to command a US Army division.
At 10:20 pm, the tank was at normal pressure, indicating the absence of water. At 10:45 pm, a shift change took place, after which the MIC storage area "would be completely deserted". During this period, a "disgruntled operator entered the storage area and hooked up one of the readily available rubber water hoses to Tank 610, with the intention of contaminating and spoiling the tank's contents." Water began to flow, beginning the chemical reaction that caused the disaster. After midnight, control room operators noticed the pressure rising and realized there was a problem with Tank 610. They discovered the water connection and decided to transfer one ton of the contents out to try to remove the water. The MIC release then occurred. The cover-up activities discovered during the investigation then took place. After over 30 years, in November 2017, S. P. Choudhary, former MIC production manager, claimed in court that the disaster was not an accident but the result of a sabotage that claimed thousands of lives. Choudhary's counsel, Anirban Roy, argued that the theory of design defects was floated by the central government in its endeavour to protect the victims of the tragedy. Everyone else involved in investigating the case "just toed the line of the central government. ... The government and the CBI suppressed the actual truth and saved the real perpetrators of the crime." Roy argued to the district court that M. L. Verma, a disgruntled plant operator at odds with senior management, was behind the sabotage.

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.
