Tesamorelin vs Sermorelin
| Attribute | Tesamorelin Stabilized GHRH analog | Sermorelin GHRH(1-29) |
|---|---|---|
| Category | Muscle Growth & Performance | Muscle Growth & Performance |
| Best known for | Visceral fat reduction research | Endogenous GH-release research |
| In plain English | Tesamorelin is the GH peptide with the strongest data for shrinking visceral (belly) fat specifically. | The original GH peptide. Sermorelin is shorter-acting and milder than CJC-1295 — researchers consider it the gentle introduction to GH peptide research. |
| How it works | Activates GHRH receptors, increasing GH and IGF-1 with documented preferential effects on visceral adipose tissue. | Stimulates pituitary GH release by binding the GHRH receptor. |
| Researchers study | Visceral fat reduction, lipid metabolism, and cognitive function in older adults. | Age-related GH decline, body composition, sleep, and pediatric GH deficiency. |
| Internet discussion | Discussed by people specifically targeting belly fat. | Older audience favors it for being well-studied with a long history. |
Tesamorelin
Visceral fat reduction research
Tesamorelin is the GH peptide with the strongest data for shrinking visceral (belly) fat specifically.
Activates GHRH receptors, increasing GH and IGF-1 with documented preferential effects on visceral adipose tissue.
Visceral fat reduction, lipid metabolism, and cognitive function in older adults.
Discussed by people specifically targeting belly fat.
Tesamorelin is the GHRH analog with strongest data for reducing visceral fat specifically.
Sermorelin
Endogenous GH-release research
The original GH peptide. Sermorelin is shorter-acting and milder than CJC-1295 — researchers consider it the gentle introduction to GH peptide research.
Stimulates pituitary GH release by binding the GHRH receptor.
Age-related GH decline, body composition, sleep, and pediatric GH deficiency.
Older audience favors it for being well-studied with a long history.
Sermorelin is the original GHRH analog with the longest research history in GH peptide work.
