Subsequently, more potent GHRPs were developed by chemical modifications.17 GHRPs have no sequential homology with GHRH and are more effective for inducing GH release even at the same dose of GHRH.18 Many studies have found that GHRPs have GH releasing activity in several species via their own receptors known as GHS receptor, not GHRH receptor.19 Recently, to overcome the limit of low oral bioavailability, peptide-mimicking and non-peptidyl GHS, which can be administered orally, were developed.4, 5, 20 SM-130686, an orally active non-peptidyl GHS, was developed and was confirmed to have GH-releasing activity
