Comparative receptor selectivity research has used MT-2 alongside Melanotan 1, PT-141, and selective MC4R agonists to dissect the relative contributions of each melanocortin receptor subtype to the full biological profile of broad melanocortin activation with studies examining how selective vs non-selective receptor engagement influences melanogenic, behavioural, and metabolic outcomes
