Tesamorelin vs HGH 191AA
GHRH analog vs exogenous recombinant GH.
| Attribute | Tesamorelin Stabilized GHRH analog | HGH 191AA Recombinant Human Growth Hormone |
|---|---|---|
| Category | Muscle Growth & Performance | Muscle Growth & Performance |
| Best known for | Visceral fat reduction research | Reference growth hormone research |
| In plain English | Tesamorelin is the GH peptide with the strongest data for shrinking visceral (belly) fat specifically. | The real thing. Where peptides stimulate the body to make more GH, HGH 191AA is the GH molecule itself. |
| How it works | Activates GHRH receptors, increasing GH and IGF-1 with documented preferential effects on visceral adipose tissue. | Binds the GH receptor across tissues, stimulating IGF-1 production, lipolysis, and protein synthesis. |
| Researchers study | Visceral fat reduction, lipid metabolism, and cognitive function in older adults. | GH deficiency, body composition, recovery, and longevity. |
| Internet discussion | Discussed by people specifically targeting belly fat. | Long-running anti-aging discussion topic. |
