- Broadening the comparison clarifies hexarelin’s position. GHRP-2 (pralmorelin) is another potent GH releaser, generally regarded as slightly less appetite-stimulating than GHRP-6 but still a meaningful trigger of cortisol and prolactin; the GHRP-2 research overview details its profile. Ipamorelin is the outlier: developed by Raun and colleagues at Novo Nordisk as “the first selective growth hormone secretagogue,” it releases GH with potency comparable to GHRP-6 but, remarkably, did not raise ACTH or cortisol even at doses more than 200-fold above its GH-releasing ED₅₀ in swine.[6] That selectivity is the key contrast: hexarelin is potent but “dirty” (it moves cortisol, prolactin, and CD36), whereas ipamorelin is potent and “clean” (GH-selective). Researchers weighing the family often frame it exactly this way, and the ipamorelin mechanism guide develops that selectivity argument in full.
