Everything below concerns regulatory status. We keep the language plain, cite what the science says, and separate well-supported claims from open questions.
Last reviewed on 2026-05-15. Where a claim depends on a specific study, the study is described rather than over-claimed.
AOD-9604 has been investigated mainly in the context of body fat and metabolic endpoints. Some early animal and small human studies reported changes in fat mass or lipid markers, but findings were not uniform. Larger, well-controlled trials that would establish efficacy are lacking in the public literature. As a result, claims about weight loss or metabolic benefit remain investigational rather than established. The distinction between a research finding and a proven clinical outcome is central to discussing this peptide.
Regulatory bodies have taken different approaches to AOD-9604. It is not approved as a prescription medicine by major agencies such as the U.S. Food and Drug Administration or the European Medicines Agency. In sport, the World Anti-Doping Agency prohibits peptide hormones, growth factors, and related substances, and AOD-9604 has been treated as a prohibited substance. These regulatory decisions reflect concerns about safety, efficacy, and potential misuse rather than proof of benefit.
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.

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.
Regulatory status: AOD-9604 is not approved as a therapeutic drug in the United States, European Union, or other major markets. It is listed by the World Anti-Doping Agency as a prohibited substance in sport, specifically under growth hormone fragments. Many jurisdictions restrict its sale for human consumption. Products marketed online may not meet pharmaceutical quality standards. The legal status varies by country and often depends on whether the material is presented as a research chemical, supplement, or drug.
Detection and characterization of AOD-9604 in research and anti-doping settings typically rely on mass spectrometry coupled with liquid chromatography. These methods can identify the peptide by its mass and fragmentation pattern. Immunoassays may also be used in some screening contexts, but they can cross-react with related peptides. Because the molecule is small and may be present at low concentrations, sample preparation and method validation are important. Confirmatory analysis usually requires comparison with a certified reference standard.
In laboratory settings, AOD-9604 is commonly supplied as a lyophilized powder and stored cold to limit degradation. Reconstituted solutions are typically kept refrigerated or frozen, depending on the buffer and concentration, and protected from repeated freeze-thaw cycles. Stability can be influenced by pH, temperature, and the presence of proteases. Purity is usually assessed by high-performance liquid chromatography and mass spectrometry. These practices support reproducibility, but they do not imply safety or efficacy for any human use.
=== Competition binding === Competition binding is used to determine the presence of selectivity for a particular ligand for receptor sub-types, which allows the determination of the density and proportion of each sub-type in the tissue. Competition curves are obtained by plotting specific binding, which is the percentage of the total binding, against the log concentration of the competing ligand. A steep competition curve is usually indicative of binding to a single population of receptors, whereas a shallow curve, or a curve with clear inflection points, is indicative of multiple populations of binding sites.
=== National Assembly === Noboa was elected to the National Assembly in the 2021 legislative elections, representing Santa Elena, for the United Ecuadorian political movement. He was inaugurated on 14 May in the same year. In that same May, he was appointed chair of the Economic Development Commission. His political ideology in the National Assembly been described as both centrist and centre-right. Noboa was absent during President Lasso's impeachment trial, however a proxy voted in the affirmative. In March 2023, he was in favor of the muerte cruzada, in the face of the rejection and filing of the Investment Law, presented by the government of Guillermo Lasso. On 17 May 2023, Lasso invoked muerte cruzada, dissolving the National Assembly and ending Noboa's tenure as an assemblyman.

Traceability: The ability to reconstruct the development history of a drug or medical device. Accountability: The ability to resolve who has contributed what to the development and when. Another version, ALCOA++, adds:
Continuous ion sources (most commonly electrospray ionization, ESI) are generally interfaced to the TOF mass analyzer by "orthogonal extraction" in which ions introduced into the TOF mass analyzer are accelerated along the axis perpendicular to their initial direction of motion. Orthogonal acceleration combined with collisional ion cooling allows separating the ion production in the ion source and mass analysis. In this technique, very high resolution can be achieved for ions produced in MALDI or ESI sources. Before entering the orthogonal acceleration region or the pulser, the ions produced in continuous (ESI) or pulsed (MALDI) sources are focused (cooled) into a beam of 1–2 mm diameter by collisions with a residual gas in RF multipole guides. A system of electrostatic lenses mounted in high-vacuum region before the pulser makes the beam parallel to minimize its divergence in the direction of acceleration. The combination of ion collisional cooling and orthogonal acceleration TOF has provided significant increase in resolution of modern TOF MS from few hundred to several tens of thousand without compromising the sensitivity.
=== Popular culture === Methaqualone factors significantly in the plot of the 1978 Cheech & Chong film Up in Smoke when character Jade East gives Man a Quaalude. Later he performs onstage at the Roxy Theatre wearing a shirt featuring the image of a pill labeled "Rorer 714". Quaaludes are mentioned in the 1983 film Scarface, when Al Pacino's character Tony Montana says, "Another Quaalude... she'll love me again." Small white pills referred to as "ludes" appear along with several other illicit drugs in the 1983 comedy-drama The Big Chill. Quaaludes are also referenced extensively in the 2013 film The Wolf of Wall Street. They are briefly mentioned in the movie Dinner in America as the reason behind the behavior of one of the characters. Almost Famous is another movie where the drug appears, as "Penny Lane", played by Kate Hudson, is shown to have taken Quaaludes during a scene in which she is drugged. Parody glam rocker "Quay Lewd", one of the costumed performance personae used by Tubes singer Fee Waybill, was named after the drug. Many songs also refer to Quaaludes, including the following: David Bowie's "Time" ("Time, in quaaludes and red wine"), and "Rebel Rebel" ("You got your cue line/And a handful of 'ludes"); "That Smell" by Lynyrd Skynyrd ("Can't speak a word when you're full of 'ludes"); "Straight Edge" by Minor Threat ("Laugh at the thought of eating ludes"); and "Nights" by Frank Ocean ("This feel like a Quaalude").

No. It is not approved as a therapeutic drug by major regulators. It is sold for research purposes in many settings, which is not the same as clinical approval.
It is classified among peptide hormones and related substances that are prohibited in sport. The ban reflects anti-doping rules rather than a judgment that the peptide is effective for performance enhancement.
Human studies are limited and have not produced consistent evidence of meaningful clinical benefit. Some early trials examined metabolic endpoints, but larger confirmatory trials are generally lacking.
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.
