02How They Differ
Tesamorelin
A stabilized GHRH(1-44) analog studied for growth-hormone-axis and lipid metabolism.
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.
Hexarelin
A growth-hormone-releasing hexapeptide studied for GHS-R and CD36 signaling.
Hexarelin is a synthetic hexapeptide growth-hormone secretagogue. It activates the ghrelin receptor (GHS-R1a) to stimulate growth-hormone release, and is distinctive in the research literature for additional interaction with the CD36 receptor, studied in cardiac-signaling models.

03Selecting for a Research Model
Because Tesamorelin and Hexarelin are both endocrine research compounds, they are frequently evaluated against one another. Selection depends on the research question, model system, and endpoints. Both are supplied strictly for laboratory research and are not for human or veterinary use.
