Ipamorelin

Ipamorelin is a synthetic pentapeptide classified as a selective growth hormone secretagogue. It functions primarily through activation of the ghrelin (GHS-R1a) receptor, stimulating endogenous growth hormone (GH) release in experimental models.

In research settings, ipamorelin has been studied for its effects on pulsatile GH secretion, insulin-like growth factor 1 (IGF-1) modulation, and anabolic-related signaling pathways. It is often examined for its receptor selectivity and comparatively minimal influence on cortisol or prolactin levels in controlled studies.
