What is the difference between GHRP-2 and GHRP-6?
Both switch on the ghrelin receptor to set off growth hormone release, and both cost about the same in this site's data. But GHRP-6 is well known for making people very hungry. GHRP-2 was made to give a similar growth hormone effect with less hunger. GHRP-2 also has an approval in Japan as a diagnostic test. GHRP-6 has no approval anywhere, and only animal work and small lab-style studies in people behind it.
