| Property | AOD-9604 | Semaglutide |
|---|---|---|
| Category | Weight Loss | Weight Loss |
| Also known as | Anti-Obesity Drug 9604, Tyr-hGH Fragment 177-191 | Ozempic, Wegovy, Rybelsus |
| FDA approved | No | Yes |
| Clinical status | Clinical trials completed without FDA approval; source also reports Sept 2024 FDA Category 2 removal, expected Category 1 reclassification activity in 2026, and GRAS status.
| FDA-approved status recorded by the supplied source; it also reports several 2025-2026 indication and formulation updates.

| What to expect | Fat loss, body composition, localized fat reduction | Weight loss, appetite control, blood sugar management |
| How it works | AOD-9604 is described as a modified fragment of human growth hormone designed around the hormone's fat-metabolism region rather than the broader growth-hormone activity profile. The source reports lab and animal findings consistent with increased lipolysis and reduced lipogenesis. It also reports no meaningful IGF-1 increase, no glucose-metabolism harm in reviewed human safety evidence, and no settled receptor explanation, so the mechanism remains proposed rather than confirmed. | According to the supplied description, semaglutide stimulates the GLP-1 receptor. Reported downstream effects include increased insulin secretion when glucose is elevated, decreased glucagon, slower gastric emptying, and hypothalamic appetite signaling. A fatty-acid modification is described as promoting albumin binding and as associated with an approximately 160 hour (about 160 hours) half-life, supporting weekly administration. |

| Typical duration | 12-24 weeks in studies | Long-term / chronic use |
| Administration | Subcutaneous injection or oral administration reported in studies | Subcutaneous injection weekly, or oral (Rybelsus) |
| Timing | Morning, fasted Empty-stomach use reported | Morning, same day each week With or without food |

| Research summary | The supplied source presents a mixed evidence picture. It describes supportive cell and animal findings for fat-metabolism effects, then reports roughly six randomized, double-blind, placebo-controlled human trials involving about 900 participants. A cited safety review is summarized as finding good tolerability, no IGF-1 elevation, no glucose-metabolism harm, and no detectable antibodies. However, the source also states that the largest Phase IIb obesity trial did not beat placebo on its main weight-loss endpoint and that Metabolic Pharmaceuticals halted development around 2007. | The source characterizes the clinical literature as extensive. It reports that the SUSTAIN program established blood-sugar control in type 2 diabetes and that SUSTAIN 6 reduced cardiovascular events. For STEP 1, published in the New England Journal of Medicine in 2021, the source describes nearly 2,000 adults without diabetes in a randomized trial: at a 68 week endpoint, semaglutide 2.4 mg had 14.9 % mean weight loss versus 2.4 % with placebo, and most participants lost at least 5 %. It characterizes this as large randomized, placebo-controlled research rather than pilot data. Gastrointestinal effects, including nausea, vomiting, and constipation, were reported as most prominent during escalation; the source also reports an oral weight-management version as approved. |
