Description
Tesamorelin is a synthetic analogue of endogenous growth hormone-releasing hormone (GHRH 1–44) bearing a trans-3-hexenoic acid modification at the N-terminus that confers markedly improved proteolytic stability compared to native GHRH. Research applications have focused on its potent and selective stimulation of pituitary somatotrophs to secrete growth hormone in a physiologically pulsatile pattern, closely mimicking endogenous hypothalamic signaling.
Animal and in vitro studies have examined tesamorelin’s downstream effects on insulin-like growth factor-1 (IGF-1) production, lipid oxidation, and visceral adipose tissue remodeling. It serves as a key reference compound for investigators examining growth hormone axis biology, metabolic dysregulation models, and the pharmacodynamic distinctions between GHRH analogues of varying structural stability. Its high receptor selectivity makes it a preferred research tool when systematic dissection of GH axis signaling is required. For laboratory research use only. Not for human or veterinary use.
