Regulation of metabolic pathways by supplementation of structural analogs of metabolites (antimetabolites) inhibiting metabolic reactions is used to search for limiting steps of biosynthesis and ways to overcome them, including development of strain antimetabolite resistance (Schmidt et al., 1996
Such circumstances may be permissive to the orexigenic effect of GHRP which otherwise would be blocked by its low-dose, GH secretagogue activity
