GHRP-2 vs GHRP-6 Hunger side effect
I've read a lot of contradicting information regarding GHRP-6 and GHRP-2 specifically with regard to the hunger side effect. I hope that this will provide some clarification regarding the matter!


GHRP-6 is sloppier in that it activates a wider array of effects beyond GH release. It causes intense hunger and gastic motility. It can have a mild (lower effect) effect on cortisol and prolactin. It is a first generation GHRP.

GHRP-2 is less sloppy with a more intense GH release, no gastric motility and less hunger effect. It can have an effect within the normal range (greater effect)on prolcatin and cortisol. It is a second generation peptide.

Ipamorelin is not sloppy at all. It does not release as much GH as GHRP-2 but it causes virtually no hunger or gastric motility and for the most part does not effect cortisol or prolactin. It is a third generation peptide

You would choose GHRP-2 unless you wanted GHRP-6 for the hunger effect or for the lower release profiles.

You would choose GHRP-2 normally as the most bang for the buck.

If you are very sensitive to perturbations in cortisol or prolactin you would choose the more expensive Ipamorelin.
