Tesamorelin vs AOD9604: What’s the Difference?
The main difference between Tesamorelin and AOD9604 is mechanism: Tesamorelin is studied for visceral fat reduction research — Stabilized GHRH analog. AOD9604 is studied for lipolysis without gh side-effects — Modified C-terminus fragment of HGH.
Visceral-fat GHRH analog vs C-terminal GH fragment.
Key differences between Tesamorelin and AOD9604
- •Mechanism: Tesamorelin — Stabilized GHRH analog. AOD9604 — Modified C-terminus fragment of HGH.
- •Primary research focus: Tesamorelin is studied for visceral fat reduction research; AOD9604 is studied for lipolysis without gh side-effects.
- •Depth of human research: Tesamorelin — Strong; AOD9604 — Strong.

| Attribute | Tesamorelin Stabilized GHRH analog | AOD9604 Anti-Obesity Drug 9604 |
|---|---|---|
| Category | Muscle Growth & Performance | Weight Loss & Metabolism |
| Best known for | Visceral fat reduction research | Lipolysis without GH side-effects |
| Mechanism of action | Stabilized GHRH analog. Notably effective at reducing visceral (abdominal) fat. | Modified C-terminus fragment of HGH. Stimulates lipolysis without affecting blood sugar or IGF-1. |
| Human research | Strong | Strong |
| Animal research | Moderate | Strong |
| Mechanistic research | Established | Established |
| Study cadence cited | Daily, typically evening | Daily, typically AM fasted |
| In plain English | Tesamorelin is the GH peptide with the strongest data for shrinking visceral (belly) fat specifically. | AOD9604 isolates the fat-burning effect of growth hormone without the muscle-building or blood-sugar effects. |
| How it works | Activates GHRH receptors, increasing GH and IGF-1 with documented preferential effects on visceral adipose tissue. | Stimulates lipolysis and inhibits lipogenesis without significant effect on IGF-1, insulin sensitivity, or glucose. |
| Researchers study | Visceral fat reduction, lipid metabolism, and cognitive function in older adults. | Obesity, body composition, and osteoarthritis (intra-articular use). |
| Internet discussion | Discussed by people specifically targeting belly fat. | Discussed for targeted fat loss. |
