Tesamorelin and Ipamorelin are synthetic peptides commonly studied for their complementary actions on the growth hormone (GH) axis. Tesamorelin, a stabilized growth hormone–releasing hormone (GHRH) analog, acts at the pituitary level to stimulate endogenous GH signaling, while Ipamorelin, a selective ghrelin (GHS-R1a) receptor agonist, augments GH pathway activation with minimal interaction with cortisol or prolactin signaling. When evaluated together, this peptide combination is investigated for its ability to support physiologic, pulsatile GH-axis signaling and downstream IGF-1–associated pathways in experimental models focused on metabolic regulation, recovery signaling, and aging-related research.
