A practical reference on AOD-9604: what it is, how it behaves, what the literature reports, and where the honest uncertainties sit.
Reviewed 2026-05-12. 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.
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 that corresponds to a short section of human growth hormone. It is commonly identified as hGH fragment 176-191 because its sequence matches residues at the C-terminal end of the hormone. The molecule contains sixteen amino acids and is made by solid-phase peptide synthesis. Researchers study it for metabolic effects rather than for the growth-promoting actions associated with full human growth hormone. Its small size distinguishes it from the complete 191-amino-acid hormone.
Several names appear in scientific and commercial settings. AOD9604 and AOD-9604 are development codes used interchangeably, while hGH fragment 176-191 describes the same region. The peptide includes a disulfide bond between two cysteine residues, which helps shape its three-dimensional structure. Different suppliers may provide acetate or other salt forms, and purity can vary. These differences matter because analytical tests and biological assays can respond to the specific form being studied.
Early interest in AOD-9604 centered on whether a fragment of human growth hormone could influence fat metabolism without the broader effects of the full hormone. Cell and animal studies reported changes in fat storage and breakdown. Human trials followed, but the results were not strong enough to secure regulatory approval. The compound remains available for laboratory research, and its clinical potential is still described as uncertain. Studies continue to examine its activity and safety profile.

Analytical characterization of AOD-9604 typically employs reversed-phase high-performance liquid chromatography (RP-HPLC) to assess purity and identity. Mass spectrometry provides confirmation of molecular mass, while amino acid analysis can verify composition. These methods are standard for peptide research chemicals. Because the peptide lacks a distinct chromophore, detection often relies on ultraviolet absorbance at 214 nm or mass spectrometric response. Laboratories may also use capillary electrophoresis for separation. For example, size-exclusion chromatography can detect aggregates.
Stability of AOD-9604 depends on storage conditions. Lyophilized powder is generally more stable than reconstituted solution. Recommended storage is typically at -20°C or lower, protected from light and moisture. Repeated freeze-thaw cycles can cause aggregation or degradation. In solution, the peptide may be susceptible to hydrolysis or oxidation, so aliquoting and cold storage are common practices. Researchers often add stabilizers such as mannitol or trehalose during lyophilization to improve shelf life.
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.
Byzantine literature concerns all Greek literature from the Middle Ages. Although the empire was linguistically diverse, the vast majority of extant texts are in medieval Greek, in two diglossic variants: a scholarly form based on Attic Greek, and a vernacular based on Koine Greek. Most contemporary scholars consider all medieval Greek texts to be literature, but some offer varying constraints. The literature's early period (c. 330–650) was dominated by the competing cultures of Hellenism, Christianity and Paganism. The Greek Church Fathers—educated in an Ancient Greek rhetoric tradition—sought to synthesise these influences. Important early writers include John Chrysostom, Pseudo-Dionysius the Areopagite and Procopius, all of whom aimed to reinvent older forms to fit the empire. Theological miracle stories were particularly innovative and popular; the Sayings of the Desert Fathers (Apophthegmata Patrum) were copied in nearly every Byzantine monastery. During the Byzantine Dark Ages (c. 650–800), production of literature mostly stopped, though some important theologians were active, such as Maximus the Confessor, Germanus I of Constantinople and John of Damascus. The subsequent cultural Macedonian Renaissance (c. 800–1000; the "Encyclopedism period") saw a renewed proliferation of literature and revived the earlier Hellenic-Christian synthesis. Works by Homer, Ancient Greek philosophers and tragedians were translated, and hagiography was heavily reorganised.

LSD's psychedelic properties were discovered 5 years later when Hofmann himself accidentally ingested an unknown quantity of the chemical. The first intentional ingestion of LSD occurred on April 19, 1943, when Hofmann ingested 250 μg of LSD. He said this would be a threshold dose based on the doses of other ergot alkaloids; however, Hofmann found the effects to be much stronger than he anticipated. Information about synthesizing LSD was first published in scientific literature by Hofmann and his colleague, psychiatrist Werner Stoll in 1943; a description of LSD's hallucinogenic effects was later published by Stoll in 1947.

=== March === March 30, 2011: Wales The global credit information group Experian highlighted in a report that the economic recovery for Wales is slower than the rest of the UK, stating a forecasted growth of 1.6% per year over the next decade as compared to 2.2% for the rest of the United Kingdom. Issues for Wales were attributed to low export rates, an unskilled workforce and low entrepreneurism, leading to less opportunities for growth.
Crocodile oil use in India is recorded in other journals, specifically, the oil is prepared by the Sanif tribe of the Punjab, who eat crocodile fat. They state crocodile oil contains larger amounts of "solidifiable fat" than any fish oil. The journal also mentions the oil to be procurable in abundance in Agra. Similarly, a journal published by Royal Society of Arts in 1879 discussed the commercial value of crocodile oil as well as how the oil was used in the nineteenth century specifically in Agra, India. A Western researcher determined that crocodile oil contained a larger proportion of solid fat either cod liver or fish oils. They softened the quality of various animal oils on leather and found leather treated with crocodile oil remained stiffer compared to other natural oils. Melted fat of crocodile or crocodile oil was also recorded to be used for "gastric obstructions". Nature, in 1886, refers to the use of crocodile oil in Germany for leather dressing, prepared in Punjab and solidified at 33 degrees. Chinese traditional medicine as well as Southeast Asian traditional medicine uses crocodile oil and products as ointments for burns and scalds. A study tested burn wound-healing efficacy of crocodile oil through a Chinese herbal medicine called crocodile oil burn ointment, consisting of crocodile oil, natural mineral and extraction of other herbal medicines by employing second-degree burns in rats and found crocodile oil enhances burn wound healing capabilities.
According to a 2011 USDA Foreign Agricultural Service report, most of the clientele of traditional open-air markets in Nigeria are low and middle income consumers. From 2008 to 2009, a group of food safety researchers launched an initiative working with a small group of butchers in the fresh food section of Bodija Market in Ibadan to promote positive food safety practices and peer-to-peer training. The initiative led to 20% more meat samples being of acceptable quality. A follow-up study in 2019 on the same group of butchers found that, while many of the butchers still remembered the food safety practices, "none of the butchers reported that they continued to buy and replace the materials after the exhaustion of those distributed during the intervention programme". The follow-up study found that the microbiological sanitation in 2018 was even worse than before the 2008–2009 intervention. In 2014, the license of the slaughterhouse in the fresh food section of Bodija Market was revoked due to unhygienic meat handling practices. In its place, the local government opened the Ibadan Central Abattoir in Amosun Village, Akinyele through public-private partnerships. The new facility is equipped with modern facilities for slaughter and processing of meat were provided in 2014 through public-private partnerships and is one of the largest abattoirs in West Africa, consisting of 15 hectares of land with stalls for 1000 meat sellers, 170 shops, administrative building, clinic, canteen, cold room, and an incinerator.

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.
AOD-9604 is a synthetic peptide fragment of human growth hormone. It corresponds to the C-terminal region known as hGH 176-191 and is studied for metabolic effects. It is not an approved therapeutic drug.
