Ipamorelins selectivity for GH release over cortisol, ACTH, and prolactin co-stimulation is conferred primarily by its Aib (-aminoisobutyric acid) substitution a non-natural alpha-methyl amino acid that constrains the peptide backbone conformation in a manner that optimises GHS-R1a engagement at somatotrophs while reducing interactions with GHS-R1a expressing hypothalamic CRH neurons responsible for ACTH/cortisol co-stimulation
