- Ipamorelin represents the selectivity end of the GHRP spectrum while hexarelin occupies the potency end. Ipamorelin was developed specifically as a selective GH secretagogue, meaning it releases growth hormone without significantly affecting cortisol, prolactin, or other hormones.
- Research demonstrates ipamorelin does not release ACTH or cortisol at levels significantly different from natural GHRH stimulation, even at doses over 200 times higher than the effective dose for GH release. Hexarelin, conversely, produces dose-dependent elevations in both cortisol and prolactin alongside its more powerful GH release.
- For researchers prioritizing clean GH elevation without hormonal disruption, ipamorelin offers advantages. For those seeking maximum GH amplitude and willing to manage additional hormonal effects, hexarelin delivers superior potency. The choice depends on research priorities rather than one being categorically better.
