Research Comparison
Ipamorelin and Tesamorelin both influence the growth-hormone axis but through different mechanisms. Ipamorelin is a GH secretagogue acting on GHSR-1a, whereas Tesamorelin is a stabilized GHRH (GRF 1-44) analog acting on the GHRH receptor.
| Attribute | Ipamorelin | Tesamorelin |
|---|---|---|
| Receptor target | GHSR-1a | GHRH receptor |
| Class | GH secretagogue | GHRH analog |
| Research focus | Pulsatile GH release | GH axis + lipid metabolism |
| Signaling | Short, pulsatile | GHRH-receptor mediated |
No. Tesamorelin is a GHRH analog acting on the GHRH receptor, while Ipamorelin is a secretagogue acting on GHSR-1a. The two act on different receptors of the same axis.
