Question: what is the difference between ghrp-6 and ghrp-2?
Answer: GHRP-2 was found to stimulate GH release from rat pituitary cells via the same receptor, with a slight variation when compared to GHRP-6. GHRP-2 increases intracellular adenosine 3,5-monophosphate cAMP concentration like that of Growth Releasing Factor (GRF) while GHRP-6 causes a decrease in cAMP levels.
