cAMP/PKA Steroidogenic Signalling In primary mouse Leydig cell cultures, hCG was found to be approximately 10-fold more potent than LH in cAMP recruitment, and slightly but significantly more potent in cAMP-dependent Erk1/2 phosphorylation though no significant differences were observed at the level of downstream steroidogenic events including Creb phosphorylation, Stard1 gene expression, and testosterone synthesis
During a three-week treatment period, both Cagrilintide and salmon calcitonin (sCT), another amylin receptor agonist, produced an acute reduction in food intake in WT mice on day 1 by 53% and 42%, respectively, but not in RAMP1/3 KO mice

The absence of direct comparative data means that claims of superiority for any one peptide over another are not supported by current evidence
