AOD9604 comes up often in conversation and rarely with the context attached. Here we lay out the basics in order, then work through the practical considerations.
Updated 2026-02-15. Numbers and descriptions here follow the published literature rather than marketing material.
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.
Laboratory studies have reported that AOD9604 can increase lipolysis and reduce lipid accumulation in fat cells. The precise molecular target remains uncertain, and the compound does not appear to activate the growth hormone receptor in the same way as full-length hGH. Proposed mechanisms include effects on beta-adrenergic signaling and enzymes involved in fatty acid synthesis, but these pathways are not firmly established. Because most evidence comes from cell and animal models, whether the same effects occur in humans is an open question.
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.

The peptide is frequently described as a growth hormone fragment, although it is chemically distinct from full-length hGH. AOD-9604 contains 16 amino acids and includes two cysteine residues that can form an intramolecular disulfide bond. In solution, this structural feature can influence folding, aggregation, and stability. Published descriptions sometimes call it hGH 176-191 or AOD9604, with spacing and capitalization varying. Such naming differences can complicate literature searches, database entries, and product verification.
Researchers have studied the fragment in cell and animal models to understand its metabolic actions. Some experiments report effects on fat breakdown and fat storage pathways, but the underlying mechanism remains incompletely defined. AOD-9604 does not appear to stimulate the same broad growth hormone receptor signaling as full-length hGH. Whether its observed activities arise from direct receptor interactions or downstream metabolic changes is an open question. Results from different assays are not always consistent.
AOD-9604 is a synthetic peptide whose sequence is modeled on the C-terminal region of human growth hormone. Published descriptions commonly place it as a modified fragment corresponding to hGH amino acids 176–191, with a tyrosine residue added or retained at the N-terminus to support detection and handling. It is not intact growth hormone and lacks the full receptor-binding architecture of the parent protein. The molecule was developed as a research candidate for metabolic studies rather than as a replacement for growth hormone therapy. Its identity is defined by its amino acid sequence rather than by any single commercial preparation.
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.
Although Parsons had said he wanted his body cremated at Joshua Tree and his ashes spread over the formation Cap Rock, Parsons' stepfather organized a private ceremony in New Orleans and left the body in the care of a funeral home. But, to fulfill Parsons' wishes, Kaufman and a friend stole both a hearse and his body and drove it to Joshua Tree. At Cap Rock Parking Lot, they poured gasoline into the open coffin and lit it, creating an enormous fireball. They were arrested and eventually fined $750 for stealing the coffin. What remained of Parsons' body was buried in Garden of Memories Cemetery in Metairie, Louisiana. The story brings Parsons fans out to a large rock flake informally known to rock climbers as the Gram Parsons Memorial Hand Traverse. At some point, someone added a slab that marked Parsons' cremation to the memorial rock; that slab was removed by the US National Park Service and moved to the Joshua Tree Inn. Joshua Tree park guides are given the option to tell the story of Parsons' cremation during tours, but there is no mention of the act in official maps or brochures.

Due to use of the drug for date rape and recreation, in 1998 Roche modified the formulation to give lower doses, make it less soluble, and add a blue dye for easier detection in drinks. It was never marketed in the United States, and by 2016 had been withdrawn from the markets in Spain, France, Norway, Germany, and the United Kingdom.

=== Health and death === On September 16, 1999, Barker was in Washington, D.C., to testify before Congress regarding proposed legislation that would ban captive elephants from traveling shows, such as circuses. While preparing for the presentation, Barker experienced what he called clumsiness in his right hand. Barker was admitted to George Washington University Hospital and diagnosed with a partially blocked left carotid artery. He underwent carotid endarterectomy to remove the blockage. The procedure went well enough that Barker was able to return to work within the month. Three years later, Barker had two additional health crises after taping the 30th-season finale of The Price is Right. While lying in the sun on May 30, 2002, he experienced a stroke and was hospitalized; six weeks later, on July 11, Barker underwent prostate surgery. Both hospitalizations occurred at George Washington University Hospital in Washington, D.C. and both surgeries were successful. Barker had several mild bouts with skin cancer, a result of his frequent tanning. Barker consulted a dermatologist regularly to make sure any cancers were caught and removed before they spread; they did not pose a threat to his life. During a televised interview, Barker told viewers, "I urge anyone who has spent some time in the sun, whether you're doing it now or not, go to a dermatologist once a year." On October 20, 2015, two police officers passing Barker's Los Angeles-area home saw him trip and fall on a sidewalk.

== History == Dalbavancin has undergone a phase-III clinical trial for adults with complicated skin infections, but in December 2007, the US Food and Drug Administration (FDA) said more data were needed before approval. Pfizer withdrew its marketing applications to conduct another phase-III clinical trial in September 2008. Durata Therapeutics acquired the rights to dalbavancin in December 2009, and has initiated two new phase-III clinical trials for treatment of ABSSSIs. Preliminary results in 2012 were promising. About 1,289 adults with ABSSSI were given dalbavancin or vancomycin randomly, and dalbavancin was found to exhibit efficacy comparable to vancomycin. In May 2014, dalbavancin was approved for medical use in the United States for ABSSSIs, including MRSA and Streptococcus pyogenes infections.
Soy sauce is widely used as an important flavoring and has been integrated into the traditional cuisines of many East Asian and Southeast Asian cultures. Despite their rather similar appearance, soy sauces made in different cultures and regions are different in taste, consistency, fragrance and saltiness. Soy sauce retains its quality longer when kept away from direct sunlight.

AOD9604 is a synthetic peptide based on a C-terminal segment of human growth hormone. It is manufactured by chemical peptide synthesis rather than extracted from human tissue. The sequence is often described as hGH fragment 176–191 or a close variant.
It is not approved as a prescription drug in the United States or the European Union for any indication. Regulatory status can differ by country, and it is often sold as a research chemical or in unapproved products. Such products are not equivalent to an approved medicine.
In the studies reported so far, AOD9604 does not appear to act through the growth hormone receptor and has not shown the typical IGF-1 increase caused by full-length hGH. Human data are limited, so this remains an area of uncertainty. It should not be assumed to have the same effects as hGH.
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.
