If you have been reading about AOD-9604 and want a single page that covers the useful parts, this is it: definitions, context, how it is studied, and the questions that come up repeatedly.
Last reviewed on 2026-05-20. Where a claim depends on a specific study, the study is described rather than over-claimed.
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.
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.

Commercial AOD-9604 may vary in purity, counterion content, and residual moisture. Certificates of analysis often report HPLC purity, mass confirmation, and appearance, but testing methods differ between suppliers. Independent verification is sometimes used because labeled content may not match actual peptide amount. Stability under different pH and temperature conditions is not fully standardized across studies. Researchers generally treat lyophilized material as the reference form for weighing and reconstitution. Moisture content can affect accurate mass measurement.
AOD-9604 is typically supplied as a lyophilized white to off-white powder. In this form, it is relatively stable when kept cool, dry, and protected from light. Common storage recommendations place it at −20 °C or below for long-term retention. Reconstituted solutions are less stable and are often kept at 2–8 °C for short periods. Freeze-thaw cycles should be minimized because they can promote aggregation or loss of peptide content. Vials are usually sealed under inert gas to reduce oxidation.
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.

=== Chemical synthesis === The chemical synthesis of salvinorin A has been described. A total asymmetric synthesis of salvinorin A, which relies on a transannular Michael reaction cascade to construct the ring system, was achieved as a 4.5% overall yield over 30 steps, then revised using 24 steps to yield salvinorin A in 0.15% yield. An approach to the trans-decalin ring system of salvinorin A used an intramolecular Diels-Alder reaction/Tsuji allylation strategy, and a total synthesis of salvinorin A was achieved using the intramolecular Diels-Alder / Tsuji allylation approach, combined with an asymmetric late-stage addition of the furan moiety.
=== Ownership and promotion === Knoll pharmaceuticals, originally founded in Germany in 1886, became a subsidiary of BASF (a German chemical company) in 1975. It was under their control when Vicoprofen was originally developed and approved. In March 2000, Knoll Pharmaceuticals and Abbott Laboratories, an American health care company, announced a co-promotion agreement for Vicoprofen, in which Abbott would promote Vicoprofen to its network of buyers, including physicians, hospitals, and surgical centers. In June 2002, Abbott Laboratories, paid $6.9 billion to acquire the entire Knoll pharmaceutical unit from BASF, including Vicoprofen.
Different views (also known as projections) of the chest can be obtained by changing the relative orientation of the body and the direction of the x-ray beam. The most common views are posteroanterior, anteroposterior, and lateral. In a posteroanterior (PA) view, the x-ray source is positioned so that the x-ray beam enters through the posterior (back) aspect of the chest and exits out of the anterior (front) aspect, where the beam is detected. To obtain this view, the patient stands facing a flat surface behind which is an x-ray detector. A radiation source is positioned behind the patient at a standard distance (most often 6 feet, 1,8m), and the x-ray beam is fired toward the patient. In anteroposterior (AP) views, the positions of the x-ray source and detector are reversed: the x-ray beam enters through the anterior aspect and exits through the posterior aspect of the chest. AP chest x-rays are harder to read than PA x-rays and are therefore generally reserved for situations where it is difficult for the patient to get an ordinary chest x-ray, such as when the patient is bedridden. In this situation, mobile X-ray equipment is used to obtain a lying down chest x-ray (known as a "supine film"). As a result, most supine films are also AP. Lateral views of the chest are obtained in a similar fashion as the posteroanterior views, except in the lateral view, the patient stands with both arms raised and the left side of the chest pressed against a flat surface.

=== Wealth and assets === Morea has been listed in various publications among Indian film personalities with significant net worth. As of 2025, his net worth has been estimated at over US$150 million by some sources. He is reported to own several high-end vehicles, including models such as the Rolls Royce Ghost, BMW M8, Lamborghini Sián, Mercedes GLS, Porsche 911, Ford Endeavour, as well as motorcycles like the Harley-Davidson Forty-Eight, Royal Enfield Bullet 500, and Aprilia RSV4. Reports also indicate that he owns multiple residential properties in India and abroad.
Large aromatic residues (tyrosine, phenylalanine, tryptophan) and β-branched amino acids (threonine, valine, isoleucine) are favored to be found in β-strands in the middle of β-sheets. Different types of residues (such as proline) are likely to be found in the edge strands in β-sheets, presumably to avoid the "edge-to-edge" association between proteins that might lead to aggregation and amyloid formation. A very simple structural motif involving β-strands is the β-hairpin, in which two antiparallel strands are linked by a short loop of two to five residues, of which one is frequently a glycine or a proline, both of which can assume the dihedral-angle conformations required for a tight turn or a β-bulge loop. Individual strands can also be linked in more elaborate ways with longer loops that may contain α-helices.

There are several identical designations for tissues both in plants and animals, e.g. “epidermis”. To distinguish between those tissue terms and to classify them correctly into BTO for plant tissues the prefix “plant” is placed before the term, e.g. “plant epidermis”. More than 80% of the tissue terms have definitions that describe the meaning and context. These definitions are obtained from i.e. medical dictionaries and cell line databases (Webster's Dictionary, DSMZ).
At least three isotopes of iodine are important. 129I, 131I (radioiodine) and 132I. Open air nuclear testing and the Chernobyl disaster both released iodine-131. The short-lived isotopes of iodine are particularly harmful because the thyroid collects and concentrates iodide – radioactive as well as stable. Absorption of radioiodine can lead to acute, chronic, and delayed effects. Acute effects from high doses include thyroiditis, while chronic and delayed effects include hypothyroidism, thyroid nodules, and thyroid cancer. It has been shown that the active iodine released from Chernobyl and Mayak has resulted in an increase in the incidence of thyroid cancer in the former Soviet Union. One measure which protects against the risk from radio-iodine is taking a dose of potassium iodide (KI) before exposure to radioiodine. The non-radioactive iodide "saturates" the thyroid, causing less of the radioiodine to be stored in the body. Administering potassium iodide reduces the effects of radio-iodine by 99% and is a prudent, inexpensive supplement to fallout shelters. A low-cost alternative to commercially available iodine pills is a saturated solution of potassium iodide. Long-term storage of KI is normally in the form of reagent-grade crystals. The administration of known goitrogen substances can also be used as a prophylaxis in reducing the bio-uptake of iodine, (whether it be the nutritional non-radioactive iodine-127 or radioactive iodine, radioiodine - most commonly iodine-131, as the body cannot discern between different iodine isotopes).
21% of all participants were children. No studies directly compared insulin degludec with NPH insulin. In the studies comparing insulin degludec to insulin detemir (2 RCTs) and insulin degludec to insulin glargine (4 RCTs), no clinically relevant difference was found for the outcomes of all-cause mortality, health-related quality of life (QoL), severe hypoglycemia, non-fatal myocardial infarction/stroke (NFMI/NFS), severe nocturnal hypoglycaemia, serious adverse effects (SAE) and Glycated haemoglobin A1c (HbA1c).

=== Rest of 2008 === On 1 September 2008, Antonio Cassese wrote in The Guardian that none of Russian justifications used for the invasion of Georgia "holds water" and "the 1992 agreement authorises only monitoring of internal tensions, not massive use of military force." On 9 September 2008, scholar Frederick Kagan stated before the hearing of the 110th United States Congress that Abkhaz and South Ossetian separatists were engaged in provocations against Georgia and Russian peacekeepers were illegally aiding them instead of curbing them. Michael McFaul stated, "The initial skirmishes between Ossetian and Georgian forces that first sparked this conflict in early August 2008 should have been contained." He further stated, "Nonetheless, Georgian military action within its borders can in no way be equated with or cited as an excuse for Russia's invasion and then dismemberment of a sovereign country." He went on to say that Russian actions in Georgia "were not a mere defensive reaction to Georgian military actions in South Ossetia."

== Disease relevance == MMP-3 has been implicated in exacerbating the effects of traumatic brain injury (TBI) through its disruption of the blood-brain barrier (BBB). Different studies have shown that after the brain undergoes trauma and inflammation has begun, MMP production in the brain is increased. In a study conducted using MMP-3 wild type (WT) and knockout (KO) mice, MMP-3 was shown to increase BBB permeability after traumatic injury. The WT mice were shown to have lower claudin-5 and occludin levels than the KO mice after TBI. Claudin and occludin are proteins that are essential for the formation of the tight junctions between the cells of the blood-brain barrier. Tissue from uninjured WT and KO mice brains was also treated with active MMP-3. Both the WT and KO tissues showed a drop in claudin-5, occludin, and laminin-α1 (a basal lamina protein), suggesting that MMP-3 directly destroys tight junction and basal lamina proteins. MMP-3 also does damage to the blood-spinal cord barrier (BSCB), the functional equivalent of the blood-brain barrier, after spinal cord injury (SCI). In a similar study conducted using MMP-3 WT and KO mice, MMP-3 was shown to increase BSCB permeability, with the WT mice showing greater BSCB permeability than the KO mice after spinal cord injury. The same study also found decreased BSCB permeability when spinal cord tissues were treated with a MMP-3 inhibitor. These results suggest that the presence of MMP-3 serves to increase BSCB permeability after SCI.

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.
No, it is a synthetic peptide fragment corresponding to a small portion of hGH. It is not the full 191-amino-acid hormone and does not reproduce all of hGH's effects.
