02Mechanism of Action
Tesamorelin is a stabilized analog of the full-length growth-hormone-releasing hormone GHRH(1-44). As a GHRH-receptor agonist it is studied for stimulation of endogenous growth-hormone secretion and downstream IGF-1 signaling.
Research models also examine its relationship to visceral-lipid and metabolic endpoints associated with the GH–IGF-1 axis.

05Frequently Asked Questions
What is Tesamorelin?
Tesamorelin is a stabilized GHRH(1-44) analog studied for growth-hormone-axis stimulation and IGF-1 signaling in research models. It is a research-use-only compound.
How is Tesamorelin different from Sermorelin?
Tesamorelin is based on the longer GHRH(1-44) sequence with stabilizing modifications, while Sermorelin is the GHRH(1-29) fragment; both are GHRH-receptor agonists used as research tools.
What is Tesamorelin's molecular weight?
Tesamorelin has an approximate molecular weight of 5,135.9 g/mol and CAS number 218949-48-5.
