The short version of AOD-9604 fits in a sentence. The long version — which is the one that helps — is below.
Reviewed 2026-05-25. Anything still debated is marked as such rather than presented as settled.
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.
Quality varies among research-grade suppliers, so certificates of analysis and independent testing are important for verification. A typical certificate reports purity by HPLC, identity by mass spectrometry, appearance, and sometimes residual solvents or water content. AOD9604 is often sold as a research chemical not intended for human consumption, and labels can be inaccurate. Common misconceptions include treating the peptide as a form of growth hormone, assuming supplement status, or expecting approved-drug quality from unregulated products.
AOD9604 is commonly supplied as a white to off-white lyophilized powder. The powder is typically stored at -20 °C or below, protected from light and moisture, because peptides can degrade through oxidation, hydrolysis, or aggregation. If it is reconstituted for laboratory use, an appropriate aqueous buffer or solvent is chosen, and the solution is kept cold and handled to avoid repeated freeze-thaw cycles. These practices support stability but do not imply suitability for human use.

Identity and purity are commonly checked with reversed-phase high-performance liquid chromatography and mass spectrometry. RP-HPLC separates the peptide from related impurities and can estimate purity by peak area. Mass spectrometry confirms molecular mass and helps detect sequence variants or truncations. Some laboratories use amino acid analysis or peptide mapping for additional characterization. No single method proves biological activity; these techniques establish chemical identity and purity only. They also require suitable reference standards for confident comparison.
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 is a synthetic peptide whose structure corresponds to a C-terminal segment of human growth hormone. It is often described as hGH fragment 176-191, a 16-amino-acid sequence. The peptide was designed to isolate a region of hGH associated with fat metabolism while avoiding the full hormone's growth-promoting actions. Laboratory and commercial materials typically present it as a lyophilized powder for research use. Its identity is defined by amino acid sequence, not by a single brand.
The fragment includes residues that can form an internal disulfide bond between two cysteine positions. This structural feature can influence how the peptide folds and how stable it is in solution. AOD-9604 differs from full-length hGH in size and receptor interactions; it does not contain the entire growth hormone sequence. Published descriptions sometimes use slightly different residue numbering, so sequence information should be checked against primary sources. The molecule is small compared with intact hGH, which affects analytical detection and purification approaches.
=== 2011–2012: Early career === Hibberd was drafted by the Essendon Football Club with their only selection and fourth overall in the 2011 pre-season draft. He made his AFL debut in the 139-point win against Gold Coast at Etihad Stadium in round six. He was omitted the next week for the match against West Coast, before returning in round eight in the thirty-six point win against Brisbane at the Gabba, where he recorded twenty-two disposals and was praised by then-Essendon coach, James Hird, in particular for his courage around the ball. Playing the next seven matches, he missed the round seventeen match against Adelaide at AAMI Stadium due to a hamstring injury. After playing the first five matches for the 2012 season, he suffered a hamstring injury during the first quarter of the Anzac Day clash against Collingwood in round five, which forced him to miss six weeks of football. He made his return from injury through the Victorian Football League (VFL), playing for Essendon's affiliate team, Bendigo. After playing two matches in the VFL, he returned to the AFL side for the twenty-four point win against Fremantle at Patersons Stadium in round thirteen. He played the next three matches before injuring his quad in the fifty point win against Port Adelaide at AAMI Stadium in round sixteen. He missed three weeks due to the injury and returned to the side for the twenty-four point loss against North Melbourne at Etihad Stadium in round twenty.
The eighth generation was released for the Japanese domestic market in June 1994 with front-wheel drive. The saloon version was again sold as the "Mazda Protegé" in North America, as the Mazda Artis in some South American markets, as the "Mazda Étude" in South Africa and as Mazda Allegro in Colombia. Originally there was a three-door coupé (323C/Familia Neo) available, but after sluggish sales, a hatchback version based on the facelifted Familia saloon replaced it. This generation grew considerably, with the four-door saloon's wheelbase only 5 millimetres short of the then-current Mazda 626, a mid-size car. The car was not originally offered with a 1.3-litre engine in Japan, with the lineup beginning with the bigger 1.5-litre. To close this gap in the lineup, the BG hatchback with the 1.3-litre engine was kept available until October 1996, when the new hatchback model was introduced (323P) and the smaller engine was made available. An unusual JDM station wagon model appeared in September 1994, with the discontinuation of the 1985-generation station wagon. The Mazda Familia Van offered after this year was a rebadged Nissan AD/Wingroad/Sunny California, which was essentially the station wagon version of the Nissan Sunny/Sentra/Pulsar (N14). A new model appeared in the same month, when a lean-burn version called the GS-L arrived: its Z5-DEL engine produces 94 PS (69 kW), three down on the regular Z5-DE, but gas mileage improved by ten to fifteen percent. Another loan was the 1.7-litre intercooled turbo-diesel engine purchased from Isuzu for use in saloons since October 1994.
=== Manipulating the interactions === The protein–DNA interactions can be modulated using stimuli like ionic strength of the buffer, macromolecular crowding, temperature, pH and electric field. This can lead to reversible dissociation/association of the protein–DNA complex.
=== Abortion === Kennedy is "strongly opposed" to abortion. He supported the 2022 overturning of Roe v. Wade, saying, "today's decision to return the issue of abortion to the American people and the states corrects a legal and moral error."
== Manufacturing == It is frequently sold as a sulfate salt known as hydroxychloroquine sulfate. In the sulfate salt form, 200 mg is equal to 155 mg of the pure form. Brand names of hydroxychloroquine include Plaquenil, Hydroquin, Axemal (in India), Dolquine, Quensyl, and Quinoric.
