AOD-9604 is a synthetic peptide fragment corresponding to a portion of the C-terminal region of human growth hormone. It has been promoted in some experimental and commercial settings for potential roles in fat metabolism and weight-related endpoints.

Regulatory positions and claims about AOD-9604 vary widely by region and product type. Many uses described in marketing materials are more expansive than what is supported by formal, high-quality clinical evidence.

Proposed mechanisms for AOD-9604 are based largely on preclinical work and focus on potential effects on lipid metabolism and adipose tissue. High-level themes include:

• Acting on pathways involved in fat breakdown and energy expenditure

• Attempting to separate certain metabolic effects of growth hormone from its broader endocrine footprint

How these mechanistic findings translate into meaningful, clinically relevant outcomes in humans is an area of ongoing debate and research.

In many jurisdictions, AOD-9604 is not an approved medicine for weight management or metabolic disease. It may appear in experimental protocols or in wellness-oriented products marketed around fat loss.

Because regulatory status, product quality, and evidence strength vary, any consideration of AOD-9604 should be grounded in local regulations and a clear understanding of the difference between exploratory research and established obesity or metabolic treatments.

AOD-9604 is classified as a prohibited substance by WADA under category S0 (Unapproved Substances).

Notable doping cases involving AOD-9604 include:

• Essendon Football Club (AFL): The most famous case involving AOD-9604. While players admitted to being injected with the substance, the final WADA-imposed bans were technically for Thymosin Beta-4 due to legal complexities. However, the saga highlighted AOD-9604's prohibited status.

Reported experiences include local injection-site reactions and nonspecific symptoms such as headache, fatigue, or GI upset. Robust, long-term safety data across diverse populations are relatively sparse.

As with other experimental peptides, careful attention to product sourcing, regulatory guidance, and individual risk factors is important. High-level summaries cannot substitute for rigorous safety evaluation.

AOD-9604 is a fragment of HGH (Tyr-hGH177-191) believed to influence lipid metabolism without the insulin-desensitizing effects of full HGH.

In catalogs, AOD-9604 usually appears as a lyophilized powder for reconstitution and may be positioned alongside other peptides associated with body composition themes.

Structural listings in this catalog are organizational and should not be read as endorsements of specific combinations, regimens, or use cases.

Research on AOD-9604 has examined its effects on fat metabolism and related markers in preclinical models and limited human studies. Results have generated interest but also raised questions about effect size, study design, and reproducibility.

Because the evidence base is evolving and sometimes mixed, claims about AOD-9604 should be interpreted cautiously. High-level overviews are not a substitute for critical appraisal of primary data.

Future FAQs may cover high-level questions such as how AOD-9604 relates conceptually to full-length growth hormone, what regulators have said about its marketing, and how clinicians think about experimental peptides in the context of established obesity treatments. Answers will remain educational and non-prescriptive.
