What are the main differences between GHRP-6 and GHRP-2?

GHRP-2 and GHRP-6 are both growth hormone releasing peptides, but they differ in several key ways. GHRP-2 demonstrates higher potency and stronger binding affinity to the GHS-R receptor, while GHRP-6 causes significantly more appetite stimulation shortly after dosing. GHRP-2 works by increasing intracellular cAMP levels, whereas GHRP-6 acts through an alternative pathway and has a longer half-life in circulation.
