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 2026-03-06. Where a claim depends on a specific study, the study is described rather than over-claimed.
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.
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.
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.
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 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.
Regulatory interest in AOD-9604 increased after high-profile anti-doping cases involving peptide products. In some cases, the substance was supplied under alternative names or in compounded preparations, complicating traceability. Sports tribunals and anti-doping panels have discussed whether the peptide was explicitly banned at the time of use, leading to clarifications by the World Anti-Doping Agency. For consumers and researchers, the legal status can vary by jurisdiction, and products marketed as research chemicals may lack independent quality verification.
AOD-9604 is listed as a prohibited substance in sport by the World Anti-Doping Agency. It falls under the peptide hormones, growth factors, related substances, and mimetics class on the prohibited list. Anti-doping organizations treat its presence in an athlete's sample as an adverse finding unless a therapeutic use exemption applies. The prohibition reflects concerns about performance enhancement in competitive settings and the difficulty of distinguishing exogenous peptide use from endogenous hormone fragments.
Detection of AOD-9604 in biological samples relies on analytical techniques capable of distinguishing a small synthetic peptide from related endogenous sequences. Liquid chromatography coupled with tandem mass spectrometry is commonly used for confirmatory analysis. Sample preparation may involve immunoaffinity enrichment or solid-phase extraction to concentrate the peptide. Because the molecule is small and may be present at low concentrations, assay sensitivity and specificity are ongoing analytical challenges. Laboratories also validate methods against reference materials when available.
In 1958 Pius XII approved of the image in association with the devotion to the Holy Face of Jesus, and decreed that the "Feast of the Holy Winding Sheet of Christ" be celebrated every year on Shrove Tuesday. In 1936 Pius XII had referred to the Shroud as a "holy thing perhaps like nothing else". In 1998 Pope John Paul II called the Shroud a "distinguished relic" and "a mirror of the Gospel". His successor, Pope Benedict XVI, called it an "icon written with the blood of a whipped man, crowned with thorns, crucified and pierced on his right side". In 2013 Pope Francis referred to it as an "icon of a man scourged and crucified". In 1983, archbishops of the Catholic Church and Greek Orthodox Church, as well as clergy of several Protestant churches attended a prayer service at the Shroud exhibit in Turin, where they "offered their corporate blessing" to the exhibit. In 1983 the Shroud was given to the Holy See by the House of Savoy. However, as with all relics of this kind, the Roman Catholic Church made no pronouncements on its authenticity. As with other approved Catholic devotions, the matter has been left to the personal decision of the faithful, as long as the Church does not issue a future notification to the contrary. In the Church's view, whether the cloth is authentic or not has no bearing whatsoever on the validity of what Jesus taught or on the saving power of his death and resurrection. Pope John Paul II stated in 1998 that: "Since it is not a matter of faith, the Church has no specific competence to pronounce on these questions.
The predictions of the effects of a major countervalue nuclear exchange include millions of city dweller deaths within a short period of time. Some 1980s predictions had gone further and argued that a full-scale nuclear war could eventually bring about human extinction. Such predictions, sometimes but not always based on total war with nuclear arsenals at Cold War highs, received contemporary criticism. On the other hand, some 1980s governmental predictions, such as FEMA's CRP-2B and NATO's Carte Blanche, have received criticism from groups such as the Federation of American Scientists for being overly optimistic. CRP-2B, for instance, predicted that 80% of Americans would survive a nuclear exchange with the Soviet Union, a figure that neglected nuclear war's impacts on healthcare infrastructure, the food supply, and the ecosystem and assumed that all major cities could be successfully evacuated within 3–5 days. A number of Cold War publications advocated preparations that could purportedly enable a large proportion of civilians to survive even a total nuclear war. Among these is Nuclear War Survival Skills. To avoid injury and death from a nuclear weapon's heat flash and blast effects, the two most common causes of injury from nuclear weapons, schoolchildren were taught to duck and cover by the early Cold War film of the same name. Such advice is once again being given in case of nuclear terrorist attacks.
=== Intellectual disability === Mutations in the CRBN gene are associated with autosomal recessive nonsyndromic intellectual disability, possibly as a result of dysregulation of calcium-activated potassium channels in the brain (see below) during development.
=== United States === In 1993, the product was approved for use in the US by the FDA, and its use began in 1994. The product is now sold in all 50 states. The FDA stated that food products made from rBST-treated cows are safe for human consumption, and no statistically significant difference exists between milk derived from rBST-treated and untreated cows. The FDA found BST to be biologically inactive when consumed by humans and found no biological distinction between rBST and BST. In 1990, an independent panel convened by the National Institute of Health supported the FDA opinion that milk and meat from cows supplemented with rBST is safe for human consumption.

If RA is adequate, T helper cell subtype Th1 is suppressed and subtypes Th2, Th17 and iTreg (for regulatory) are induced. Dendritic cells located in intestinal tissue have enzymes that convert retinal to all-trans-retinoic acid, to be taken up by retinoic acid receptors on lymphocytes. The process triggers gene expression that leads to T cell types Th2, Th17 and iTreg moving to and taking up residence in mesenteric lymph nodes and Peyer's patches, respectively outside and on the inner wall of the small intestine. The net effect is a down-regulation of immune activity, seen as tolerance of food allergens, and tolerance of resident bacteria and other organisms in the microbiome of the large intestine. In a vitamin A deficient state, innate immunity is compromised and pro-inflammatory Th1 cells predominate.
MHC molecules enable immune system surveillance of the population of protein molecules in a host cell, and greater MHC diversity permits greater diversity of antigen presentation. In 1976, Yamazaki et al demonstrated a sexual selection mate choice by male mice for females of a different MHC. Similar results have been obtained with fish. Some data find lower rates of early pregnancy loss in human couples of dissimilar MHC genes. MHC may be related to mate choice in some human populations, a theory that found support by studies by Ober and colleagues in 1997, as well as by Chaix and colleagues in 2008. However, the latter findings have been controversial. If it exists, the phenomenon might be mediated by olfaction, as MHC phenotype appears strongly involved in the strength and pleasantness of perceived odour of compounds from sweat. Fatty acid esters—such as methyl undecanoate, methyl decanoate, methyl nonanoate, methyl octanoate, and methyl hexanoate—show strong connection to MHC. In 1995, Claus Wedekind found that in a group of female college students who smelled T-shirts worn by male students for two nights (without deodorant, cologne, or scented soaps), the majority of women chose shirts worn by men of dissimilar MHCs, a preference reversed if the women were on oral contraceptives. In 2005 in a group of 58 subjects, women were more indecisive when presented with MHCs like their own, although with oral contraceptives, the women showed no particular preference. No studies show the extent to which odor preference determines mate selection (or vice versa).
On his retirement, Mahathir was named a Grand Commander of the Order of the Defender of the Realm, the highest honour in Malaysia, allowing him to adopt the title of "Tun". Under Mahathir's leadership, Malaysia was transformed into an industrialising nation. He pledged to leave politics "completely", rejecting an emeritus role in Abdullah's cabinet. Abdullah immediately made his mark as a quieter and less adversarial premier. With stronger religious credentials than Mahathir, he beat back PAS's surge in the 1999 election and lead the Barisan Nasional in the 2004 election to its biggest win ever, taking 199 of 219 parliamentary seats. On 23 October, Mingguan Malaysia, a Sunday edition of Utusan Malaysia, published an exclusive interview with Mahathir, marking his first since retiring as prime minister. After retiring, Mahathir maintained a busy schedule, engaging in various activities and speaking engagements both locally and internationally. In 2005, Russian president Vladimir Putin visited him at his private residence, where they held a four-hour meeting discussing Malaysia's economic transformation and development strategies. He emphasized the importance of staying active, stating, "Never retire. You have to work. When you work, it will keep you alive." His office at the Perdana Leadership Foundation and residence at the Mines Resort City, as well as expenses for meal allowances, escorts, bodyguards, a medical officer, and a special assistant during overseas trips, are funded by the government under the Member of Parliament (Remuneration) Act 1980 (Act 237).
Experiments with strains of mice engineered to remove (knockout) CYP1A1 and CYP1B1 reveal that CYP1A1 primarily acts to protect mammals from low doses of BaP, and that removing this protection accumulates large concentrations of BaP. Unless CYP1B1 is also knocked out, toxicity results from the bioactivation of BaP to benzo[a]pyrene -7,8-dihydrodiol-9,10-epoxide, the ultimate toxic compound.
==== Myotubular myopathy ==== Myotubular myopathy, also known as centronuclear myopathy, is recognized by pain during exercise and difficulty walking. People affected by this disease typically are wheelchair-reliant by middle adulthood, have weakness in the muscles involved in eye movement, nerve function disorders, and some form of intellectual disability. Myotubular myopathy is very rare, with less than 50 families currently affected. Genetically, myotubular myopathy can have two causes: autosomal dominant and autosomal recessive. When caused by a mutation in the DNM2 gene, the disorder is autosomal dominant, meaning it can be passed on by one mutated gene. When the mutation takes place in the BIN1 gene, the disease is instead autosomal recessive, and both genes must be mutated for the disease to be inherited. Autosomal recessive onset is most common.

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.
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.
