- vs. Ipamorelin: Ipamorelin is far more selective (no cortisol/prolactin elevation, minimal tachyphylaxis). Hexarelin trades selectivity and sustained responsiveness for greater acute GH pulse amplitude and the unique CD36 cardiovascular research profile.
- vs. GHRP-2: GHRP-2 has similar GHSR-1a potency and also elevates cortisol/ACTH, but lacks hexarelin's CD36 binding. GHRP-2 tachyphylaxis is somewhat less pronounced than hexarelin.
- vs. GHRP-6: GHRP-6 is the classical reference GHRP, with the most extensive literature base, significant appetite stimulation through peripheral ghrelin-like activity, and lower potency than hexarelin. CD36 activity is not a significant feature of GHRP-6.
