Ipamorelin vs GHRP-6
Both activate the GHS-R1a receptor, but their selectivity profiles diverge significantly. GHRP-6 produces robust GH release but also drives substantial increases in cortisol, prolactin, and appetite. The appetite stimulation from GHRP-6 is particularly pronoun

- Both activate the GHS-R1a receptor, but their selectivity profiles diverge significantly. GHRP-6 produces robust GH release but also drives substantial increases in cortisol, prolactin, and appetite. The appetite stimulation from GHRP-6 is particularly pronounced, a direct consequence of strong ghrelin receptor agonism in the hypothalamus. Ipamorelin achieves comparable GH output without these off-target effects, which is why it largely replaced GHRP-6 in modern stacking protocols.
