Tesamorelin
Tesamorelin is a synthetic 44-amino acid GHRH analog with a trans-3-hexenoic acid group added to the N-terminus of native GHRH(1-44). This modification enhances metabolic stability. It stimulates the GHRH receptor, promoting endogenous GH synthesis and pulsatile release from the anterior pituitary.
