Everything below concerns AOD-9604. We keep the language plain, cite what the science says, and separate well-supported claims from open questions.
Last reviewed on 2025-12-23. 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.
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.

== History == On 28 November 2016, the university came into existence via Haryana Vidhan Sabha legislature. On 18 April 2017, Chief Minister Manohar Lal Khattar's administration renamed it after the Maharana Pratap.
SOCPAC and Southern Command pushed for a significant expansion of American assistance to the Filipino Counterterrorist effort, but being that Sulu was predominantly inhabited by Muslims and was the site where Islam was introduced to the Philippines, many members of both the Philippine and US governments believed that introducing American forces onto Sulu would have been met with intense resistance. Based on a PACOM assessment recommending such a deployment, the Secretary of Defense approved a second iteration of OEF-P to combat terrorism in the Southern Command Area of Responsibility, specifically on Sulu. SOCPAC established a larger JSOTF in Zamboanga and deployed aforce package to the island of Sulu, conducting operations based on the Basilan model. Using that template, SOCPAC deployed one ODB, 5 ODAs to Sulu to advise and assist AFP units in their effort to capture key terrorists. From October 2005 to July 2006, JSOTF-P units assisted Task Force (TF) Comet-the AFP command on Sulu-in setting conditions to deny terrorist sanctuary. ODAs advised their partner army and marine infantry battalions en route and area security to facilitate Filipino sponsored medical, veterinary, and engineer civilian action programs, along with various population engagement activities. These combined efforts succeeded in separating the terrorists from the population. On 27 October 2007, a U.S. Special Forces soldier from 2nd Battalion, 1st SFG was killed in an accidental drowning incident at Lake Seit in the southern Philippines. On 29 September 2009, a roadside bomb killed two U.S.
An erogenous zone (from Greek ἔρως, érōs "love"; and English -genous "producing", from Greek -γενής, -genḗs "born") is an area of the human body that has heightened sensitivity, the stimulation of which may generate a sexual response such as relaxation, sexual fantasies, sexual arousal, and orgasm. Erogenous zones are located all over the human body; however, the degree of sensitivity varies among individuals and is influenced by the concentration of nerve endings that can provide pleasurable sensations when stimulated. The act of physically touching of another person's erogenous zone is regarded as an act of physical intimacy. Whether a person finds stimulation in these areas to be pleasurable or objectionable depends on a range of factors, including their level of arousal, the circumstances in which it takes place, the cultural context, the nature of the relationship between the partners, and the partners' personal histories. Erogenous zones may be classified by the type of sexual response that they generate. Many people are gently aroused when their eyelids, eyebrows, temples, shoulders, hands, arms, and hair are subtly touched. Gentle touching or stroking of these zones stimulates a partner during foreplay to increase the arousal level. Additionally, the gentle massage or stroke of the abdominal area, along with kissing or simply touching the navel, can serve as a form of stimulation.

== Clinical presentation == Patients with hemoglobin H disease present with chronic hemolytic anemia that ranges in severity from mild to moderate disease. Anemia is the most common presenting symptom of patients with HbH disease. Other common clinical features include jaundice, splenomegaly, hepatomegaly, and gallstones. All of these symptoms are related to the destruction of the red blood cells in the spleen and the associated increased hemoglobin metabolism. Patients with non-deletional HbH disease are more likely to be symptomatic and have severe disease presentation when compared to individuals with deletional HbH disease. Disease presentation varies from asymptomatic individuals to neonatal growth retardation and death in the most severe cases. Death in the neonatal period occurs due to the severe anemia resulting in hydrops fetalis. Patients most often present initially due to hemolytic episodes that occur during times of infection or inflammation. During these episodes, patients may develop hemolytic crisis, in which there is a rapid drop in the hemoglobin due to increased red blood cell destruction.
== Prevention == In the past, the prophylactic use of dantrolene was recommended for MH-susceptible patients undergoing general anesthesia. However, multiple retrospective studies have demonstrated the safety of trigger-free general anesthesia in these patients in the absence of prophylactic dantrolene administration. The largest of these studies looked at the charts of 2214 patients who underwent general or regional anesthesia for an elective muscle biopsy. About half (1082) of the patients were muscle biopsy positive for MH. Only five of these patients exhibited signs consistent with MH, four of which were treated successfully with parenteral dantrolene, and the remaining one recovered with only symptomatic therapy. After weighing its questionable benefits against its possible adverse effects (including nausea, vomiting, muscle weakness and prolonged duration of action of nondepolarizing neuromuscular blocking agents), experts no longer recommend the use of prophylactic dantrolene prior to trigger-free general anesthesia in MH-susceptible patients.
The Stuart Patton Auditorium in the Agricultural Sciences and Industries Building at Penn State is dedicated in his honor “for his inquisitive nature and skill in imparting knowledge; for his enthusiasm for science and uncompromising respect for peers.” In 2018, Dr. Patton's colleague, Ian H. Mather, added this touching tribute to Patton in his article in the Journal of Dairy Science: "This review is dedicated to the memory of Stuart Patton (1920–2017), Evan Pugh Professor Emeritus, Pennsylvania State University, and colleague, friend, and unofficial mentor of the senior author (IHM). The footprints of Dr. Patton’s research are evident throughout the pages of this review" (article is Symposium Review: Intravital imaging of the lactating mammary gland in live mice reveals novel aspects of milk-lipid secretion In a letter submitted in support of Patton's nomination as a fellow of the American Dairy Science Association in 2001, Dr. Ian Maher stated the following, "Dr. Patton's research is characterized by careful attention to experimental detail and a thorough knowledge of the literature. The discussion sections of his papers are always brimming with ideas, thought provoking and creative. A consistent feature of the work is novelty, whether it is a simple solution to a practical problem, or an inspirational idea that leads to new avenues of research. An example of the former is the simple but elegant method Dr. Patton devised to separate milk-fat globules from skim-milk components in a single step by density gradient centrifugation (Patton, S., and Huston, G.E.

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.
