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 2025-10-27. Where a claim depends on a specific study, the study is described rather than over-claimed.
Regulatory status varies by country. In the United States, AOD-9604 is not approved as a prescription drug. It is sometimes sold as a research chemical or dietary supplement, though such marketing may fall outside legal frameworks. The World Anti-Doping Agency prohibits its use in sport. Researchers must obtain it through legitimate suppliers and follow institutional rules. Its legal classification continues to evolve as authorities increasingly assess peptide products more broadly.
AOD-9604 is a synthetic peptide whose sequence matches the C-terminal fragment of human growth hormone, specifically residues 176 through 191. This region differs from the full hormone in its receptor interactions. The peptide is not a growth hormone secretagogue and does not bind the growth hormone receptor in the same manner. Researchers have examined it for effects on lipid metabolism, but its exact pharmacological profile remains an active area of study.
Development of AOD-9604 began in the 1990s as scientists sought to isolate metabolic effects of growth hormone without its growth-promoting actions. Early laboratory work focused on fat cells and animal models. Several human trials followed, examining changes in body composition and fat mass. Results have been mixed, and the peptide has not progressed to widespread clinical approval. Interest continues in research settings, particularly regarding its mechanism and potential metabolic targets.
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.
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.

=== FCPA bribery lawsuits === From 2005 to 2010, Bio-Rad subsidiaries made bribes to foreign government officials, and made other payments intentionally ignoring the high likelihood of bribery. The bribes were estimated to have made $35.1 million profit for Bio-Rad, primarily from sales in Russia, Vietnam, and Thailand:
=== Agricultural feed === A wide variety of agroindustrial waste products can be fermented to use as food for animals, especially ruminants. Fungi have been employed to break down cellulosic wastes to increase protein content and improve in vitro digestibility.
They played their last ever international on 21 June 2006, a 3–2 loss to Ivory Coast. Following the World Cup, this team has been inherited by Serbia, while a new one was to be organized to represent Montenegro in future international competitions.
== Epidemiology == Many over-the-counter and prescription-only medications contain paracetamol. Because of its wide availability paired with comparably high toxicity, (compared to ibuprofen and aspirin) there is a much higher potential for overdose. Paracetamol toxicity is one of the most common causes of poisoning worldwide. In the United States, the United Kingdom, Australia, and New Zealand, paracetamol is the most common cause of drug overdoses. Additionally, in both the United States and the United Kingdom it is the most common cause of acute liver failure. In England and Wales an estimated 41,200 cases of paracetamol poisoning occurred in 1989 to 1990, with a mortality of 0.40%. It is estimated that 150 to 200 deaths and 15 to 20 liver transplants occur as a result of poisoning each year in England and Wales. Paracetamol overdose results in more calls to poison control centers in the US than overdose of any other pharmacological substance, accounting for more than 100,000 calls, as well as 56,000 emergency room visits, 2,600 hospitalizations, and 458 deaths due to acute liver failure per year. A study of cases of acute liver failure between November 2000 and October 2004 by the Centers for Disease Control and Prevention in the US found that paracetamol was the cause of 41% of all cases in adults, and 25% of cases in children.

Nonbenzodiazepines (Z-drugs) are a class of psychoactive drugs that are "benzodiazepine-like" in nature. Nonbenzodiazepine pharmacodynamics are almost entirely the same as benzodiazepine drugs, and therefore entail similar benefits, side effects, and risks. Nonbenzodiazepines, however, have dissimilar or different chemical structures, and are unrelated to benzodiazepines on a molecular level. Examples include zopiclone (Imovane), eszopiclone (Lunesta), zaleplon (Sonata), and zolpidem (Ambien). Since the generic names of all drugs of this type start with Z, they are often referred to as Z-drugs. Research on nonbenzodiazepines is new and conflicting. A review by a team of researchers suggests the use of these drugs for people who have trouble falling asleep (but not staying asleep), as next-day impairments were minimal. The team noted that the safety of these drugs had been established, but called for more research into their long-term effectiveness in treating insomnia. Other evidence suggests that tolerance to nonbenzodiazepines may be slower to develop than with benzodiazepines. A different team was more skeptical, finding little benefit over benzodiazepines.

=== Persufflation === Blood can be replaced with inert noble gases and/or metabolically vital gases like oxygen, so that organs can cool more quickly and less antifreeze is needed. Since regions of tissue are separated by gas, small expansions do not accumulate, thereby protecting against shattering. Pressures of 60 atm can help increase heat exchange rates. Gaseous oxygen perfusion / persufflation can enhance organ preservation relative to static cold storage or hypothermic machine perfusion, since the lower viscosity of gases, may help reach more regions of preserved organs and deliver more oxygen per gram tissue.
The British Colonial Secretary, Joseph Chamberlain, though sympathetic to the ultimate goals of the raid, realized it would be a mistake since the uitlanders were not supportive. He immediately tried to stop it, remarking that "if this succeeds it will ruin me. I'm going up to London to crush it". He rushed back to London and ordered Sir Hercules Robinson, governor of the Cape Colony, to repudiate the actions of Jameson and warned Rhodes that the company's charter would be in danger if it were discovered the Cape Prime Minister was involved in the raid. Chamberlain therefore instructed local British representatives to call on British colonists not to offer any aid to the raiders.

AOD-9604 is a synthetic peptide fragment of human growth hormone, corresponding to amino acids 176-191. It is studied for potential effects on fat metabolism, but it is not approved as a drug in most countries. Its exact mechanism remains under investigation.
No, it is a small fragment of the full growth hormone protein. It does not appear to stimulate growth or increase growth hormone levels in the same way. Its actions are thought to be more limited to metabolic pathways.
Regulatory status varies. It is not approved for medical use in the United States or many other countries. It is banned in sport by WADA, and its sale as a supplement or research chemical may be subject to legal restrictions.
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.
