A practical reference on AOD-9604: what it is, how it behaves, what the literature reports, and where the honest uncertainties sit.
This page was last updated on 2026-05-11 and is reviewed periodically as new material appears.
Regulatory treatment of AOD-9604 is shaped by its classification as a peptide hormone. The World Anti-Doping Agency lists it as a prohibited substance, and many national anti-doping organizations adopt that list. It does not hold approval as a prescription medicine in the United States, the European Union, or other major markets. Products sold online are frequently labeled for research use only and may not undergo independent quality testing. Import and possession rules differ by country, so legal status depends on local law.
Proposed mechanisms for AOD-9604 focus on fat cells. Laboratory studies suggest the peptide can increase lipolysis, the breakdown of stored fat, and reduce lipogenesis, the formation of new fat. Unlike full human growth hormone, it does not appear to stimulate substantial IGF-1 production in the studies reported so far. Some evidence points to beta-adrenergic signaling, but the precise receptor targets and downstream pathways remain unresolved. The fragment is not thought to act through the classical growth hormone receptor.
Clinical development of AOD-9604 included trials in people with obesity. Reports from early-phase and mid-phase studies described modest or inconsistent changes in body weight. A phase IIb program did not meet its primary endpoint, and the compound was not approved for medical use. Differences in formulation, delivery route, and participant characteristics may explain some of the variation. Later investigations explored whether the peptide might have effects in other tissues, including cartilage.
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.
| Property | Value | Notes |

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 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.
A central uncertainty is whether observed metabolic changes translate into meaningful clinical benefits. Study designs vary in dose, duration, and participant characteristics, making comparisons difficult. Independent replication is limited, and the field lacks consensus on optimal endpoints or treatment duration. Ongoing or future studies may clarify mechanism and effect size, but current evidence does not establish a clear therapeutic role. Researchers often call for larger, longer, and better-controlled trials, while questions remain about which patient groups might respond.
Proposed mechanism focuses on lipolysis, the breakdown of stored triglycerides into free fatty acids and glycerol. AOD-9604 is thought to act on adipose tissue without stimulating appetite or affecting blood sugar in the same way as growth hormone. Laboratory studies report increased fat oxidation in some models. The precise receptor interactions and signaling pathways remain incompletely characterized. Researchers have proposed that the peptide may influence fat mobilization through pathways distinct from the full hormone.
== Disorders == Hyperactivity of theca cells causes hyperandrogenism, and hypoactivity leads to a lack of estrogen. Granulosa cell tumors, while rare (less than 5% of ovarian cancers), may occur in both granulosa cells and theca cells. Thecomas are benign proliferations of theca cells that may present with hormonal dysfunction. Dysfunction in theca cells is one of the leading cause of endocrine-based infertility, as either hyperactivity or hypoactivity of the theca cells can lead to fertility problems.
== Prognosis == A typical patient with severe McLeod syndrome that begins in adulthood lives for an additional 5 to 10 years. Patients with cardiomyopathy have elevated risk for congestive heart failure and sudden cardiac death. The prognosis for a normal life span is often good in some patients with mild neurological or cardiac sequelae.
== Authority opinions == The National Academy of Medicine recommends a daily average of 130 g of carbohydrates per day. The FAO and WHO similarly recommend that the majority of dietary energy come from carbohydrates. Low-carbohydrate diets are not an option recommended in the 2015–2020 edition of Dietary Guidelines for Americans, which instead recommends a low-fat diet. Carbohydrate has been wrongly accused of being a uniquely "fattening" macronutrient, misleading many dieters into compromising the nutritiousness of their diet by eliminating carbohydrate-rich food. Low-carbohydrate diet proponents emphasize research saying that low-carbohydrate diets can initially cause slightly greater weight loss than a balanced diet, but any such advantage does not persist. In the long-term successful weight maintenance is determined by calorie intake, and not by macronutrient ratios. The public has become confused by the way in which some diets, such as the Zone diet and the South Beach diet are promoted as "low-carbohydrate" when in fact they would more properly be termed "medium-carbohydrate" diets.

The primary purpose of the electrocardiogram is to detect ischemia or acute coronary injury in broad, symptomatic emergency department populations. A serial ECG may be used to follow rapid changes in time. The standard 12 lead ECG does not directly examine the right ventricle, and is relatively poor at examining the posterior basal and lateral walls of the left ventricle. In particular, acute myocardial infarction in the distribution of the circumflex artery is likely to produce a nondiagnostic ECG. The use of additional ECG leads like right-sided leads V3R and V4R and posterior leads V7, V8, and V9 may improve sensitivity for right ventricular and posterior myocardial infarction. The 12 lead ECG is used to classify patients into one of three groups:

==== Martyrs ==== The decision as to whether martyrs had died for their faith in Christ and the consequent permission of veneration lay originally with the bishop of the place in which they had borne their testimony. The bishop inquired into the motive of the person's death and, on finding they had died a martyr, sent their name with an account of their martyrdom to other churches, especially neighboring ones, so that, in the event of approval by their respective bishops, the cultus of the martyr might extend to their churches also and that the faithful, as is said of Ignatius of Antioch in the "Acts" of his martyrdom "might hold communion with the generous martyr of Christ" (generoso Christi martyri communicarent). Martyrs whose cause, so to speak, had been discussed, and the fame of whose martyrdom had been confirmed, were known as proved (vindicati) martyrs. That word probably did not antedate the fourth century, when it was introduced into the Church at Carthage; but the fact is certainly older. In the earlier ages, therefore, this veneration was entirely local and passed from one church to another with the permission of their bishops. This is clear from the fact that in ancient Christian cemeteries there are found paintings of only those martyrs who had suffered in that neighborhood. It explains, also, the almost universal veneration very quickly paid to, e.g., Lawrence, Cyprian, and Sixtus II, who were killed by the Roman Emperor Valerian.

Legumin is a conjugated protein with six subunits. The individual subunits have a hydrophilic α chain that is initially linked to the smaller hydrophobic β chain with a peptide bond. Both the α and β chains are encoded by the same gene. Each of the six subunits has a mass of ~50-60 kDa. During translation of the α and β chains, the polypeptide is inserted into the endoplasmic reticulum (ER) where the signal peptide that initiated the cell to translocate the chains is cleaved. A disulfide bridge is formed between the α and β chains to form prolegumin, a protein precursor. Three of these subunits come together to form a trimer in the ER. The trimer of prolegumins can be transported to the vacuole for further post-translational modification. In the vacuole, the peptide bond formed between the α and β chains is cleaved now that the disulfide bridge holds the two chains together. The cleavage of the α and β chains within the trimers signals protein maturation where two trimers to come together and form the final hexameric legumin protein.

==== Hybrid Closed Loop (HCL) / Advanced Hybrid Closed Loop (AHCL) ==== Hybrid closed loop (HCL) systems further expand on the capabilities of PLGS systems by adjusting basal insulin delivery rates both up and down in response to values from a continuous glucose monitor. Through this modulation of basal insulin, the system is able to reduce the magnitude and duration both hyperglycemic and hypoglycemic events. Users still must initiate manual mealtime boluses. Advanced hybrid closed loop systems have advanced algorithms. Fully Closed Loop (FCL) Fully or full closed loop (FCL) systems adjust insulin delivery in response to changes in glucose levels without requiring input by users for mealtime insulin or announcements of meals.
In a study on female volunteers under hypnosis, prolactin surges resulted from the evocation, with rage, of humiliating experiences, but not from the fantasy of nursing. Stress-induced PRL changes are not linked to the posterior pituitary in rodents. Hypersecretion is more common than hyposecretion. Hyperprolactinemia is the most frequent abnormality of the anterior pituitary tumors, termed prolactinomas. Prolactinomas may disrupt the hypothalamic–pituitary–gonadal axis as prolactin tends to suppress the secretion of gonadotropin-releasing hormone from the hypothalamus and in turn decreases the secretion of follicle-stimulating hormone and luteinizing hormone from the anterior pituitary, therefore disrupting the ovulatory cycle. Such hormonal changes may manifest as amenorrhea and infertility in females as well as erectile dysfunction in males. Inappropriate lactation (galactorrhoea) is another important clinical sign of prolactinomas.
Gentle, non-irritating cleansers and moisturizers are often used alongside medicated treatments to maintain the skin barrier. The condition is common in infants within the first three months of age and adults aged 30 to 70 years. It is more common in males, African Americans, the immunocompromised (such as those with HIV), and those with Parkinson's disease.
primary reconstruction: the replacement of breast tissues damaged by trauma (blunt, penetrating, blast), disease (breast cancer), and failed anatomic development (tuberous breast deformity). revision and reconstruction: to revise (correct) the outcome of a previous breast reconstruction surgery. primary augmentation: to aesthetically augment the size, form, and feel of the breasts. The operating room time of post–mastectomy breast reconstruction, and of breast augmentation surgery is determined by the procedure employed, the type of incisions, the breast implant (type and materials), and the pectoral locale of the implant pocket. Recent research has indicated that mammograms should not be done with any greater frequency than that used in normal procedure in patients undergoing breast surgery, including breast implant, augmentation, mastopexy, and breast reduction.
Protein A/G is a recombinant fusion protein that combines IgG binding domains of both protein A and protein G. Protein A/G contains four Fc binding domains from protein A and two from protein G, yielding a final mass of 50,460 daltons. The binding of protein A/G is less pH-dependent than protein A, but otherwise has the additive properties of protein A and G. Protein A/G binds to all subclasses of human IgG, making it useful for purifying polyclonal or monoclonal IgG antibodies whose subclasses have not been determined. In addition, it binds to IgA, IgE, IgM and (to a lesser extent) IgD. Protein A/G also binds to all subclasses of mouse IgG but does not bind mouse IgA, IgM or serum albumin. This allows Protein A/G to be used for purification and detection of mouse monoclonal IgG antibodies, without interference from IgA, IgM and serum albumin. Mouse monoclonal antibodies commonly have a stronger affinity to the chimeric protein A/G than to either protein A or protein G. Protein A/G also has been used for purification of macaque IgG.

No. Major drug regulators have not approved AOD-9604 for weight loss or any other therapeutic indication. It remains an investigational compound studied in research settings.
The World Anti-Doping Agency classifies it as a prohibited peptide hormone. Athletes under anti-doping rules are not permitted to use it. Its presence can trigger a doping violation.
It is a fragment of growth hormone rather than a substance that signals the pituitary to release more hormone. Studies have not shown a consistent rise in IGF-1 or full growth hormone. Its metabolic effects, if any, appear separate from those of the complete hormone.
Lyophilized powder is commonly stored at −20 °C or below, protected from light and moisture. Reconstituted solutions are typically kept refrigerated and used within a limited period.
