1. Tesamorelin vs Ipamorelin: Mechanism of Action



Both peptides are designed to influence growth hormone (GH) dynamics, but they do so through distinct pathways.





Tesamorelin is a synthetic analogue of growth-hormone-releasing hormone (GHRH). It binds directly to the GHRH receptor on pituitary somatotrophs, stimulating endogenous GH secretion. The released GH then activates insulin-like growth factor-1 (IGF-1) production in peripheral tissues, promoting lipolysis and metabolic benefits.



Ipamorelin is a selective growth hormone secretagogue that targets the ghrelin receptor (GHSR). Unlike ghrelin itself, Ipamorelin does not trigger significant appetite stimulation. Instead, it activates the GHSR to provoke GH release in a more physiologic, pulsatile pattern, which can enhance muscle anabolism and recovery.



The differing receptor targets mean that Tesamorelin’s action is more linear and potent per dose, whereas Ipamorelin offers a subtler, potentially safer profile for regular use.

Tesamorelin is primarily approved for reducing excess abdominal fat in HIV-associated lipodystrophy but has broader applications in metabolic health.
